Apr 25, Author: Ali Nawaz Khan, MBBS, FRCS, FRCP, FRCR; Chief Editor: They are native veins that serve as collaterals to the central varice eliminate circulation when flow through the portal venous system or superior vena cava SVC is obstructed. Esophageal varices are collateral veins within the wall of the esophagus that project directly into the lumen. The veins are of clinical concern because they are prone to hemorrhage.

Varice eliminate varices are collateral veins beyond the adventitial surface varice eliminate the esophagus that parallel intramural esophageal veins. Paraesophageal varices are less prone to hemorrhage. Esophageal and paraesophageal varices are slightly different in venous origin, but they are usually found together.

Using a thin-barium technique, radiographic appearances of esophageal varices were described first by Wolf varice eliminate his paper, "Die Erkennug von osophagus varizen im rontgenbilde," or "Radiographic detection of esophageal varices. Today, more sophisticated imaging with computed tomography CT scanning, magnetic resonance imaging MRImagnetic resonance angiography MRAand varice eliminate ultrasonography EUS plays an important role in varice eliminate evaluation of portal hypertension and esophageal varices.

Endoscopy is the criterion standard for evaluating esophageal varices and assessing the bleeding risk. The esophageal varices are also inspected for red wheals, which are dilated intra-epithelial veins under tension which carry a significant risk for bleeding.

Varice eliminate is also used for interventions. The following pictures demonstrate band ligation of esophageal varices. CT scanning and MRI are identical in their usefulness in diagnosing and evaluating the extent of esophageal varices. These modalities have an advantage over endoscopy because CT scanning and MRI can help in evaluating the surrounding anatomic structures, both above and below the diaphragm.

CT scanning and MRI are also valuable in evaluating the liver and varice eliminate entire portal circulation. These modalities are used in preparation for a transjugular intrahepatic portosystemic shunt TIPS procedure or liver transplantation and in evaluating for a specific etiology of esophageal varices.

These modalities also have an advantage over both endoscopy and angiography because they are noninvasive. CT scanning and MRI do not have strict criteria for evaluating the bleeding risk, and they are not as sensitive or specific as endoscopy.

CT scanning and MRI varice eliminate be used as alternative methods in making the diagnosis if endoscopy is contraindicated eg, in patients with a recent myocardial infarction or any contraindication to sedation.

In the past, angiography was considered the criterion standard for evaluation of the portal venous system. However, current CT scanning and MRI procedures sekundГre țelină cu varice Erscheinungen become equally just click for source and specific varice eliminate the detection of esophageal varices and other abnormalities of the portal venous system.

Although the surrounding anatomy cannot be evaluated the way they can be with CT scanning or MRI, angiography is advantageous because its use may be therapeutic as well as diagnostic. In addition, angiography may be performed if CT varice eliminate or MRI findings are inconclusive.

Ultrasonography, excluding EUS, and nuclear medicine studies are of minor significance in the evaluation of esophageal varices. Although endoscopy is the criterion standard in diagnosing and varice eliminate esophageal varices, the anatomy outside of the esophageal mucosa cannot be evaluated with this technique.

Therefore, imaging modalities such as CT scanning, MRI, and EUS are also performed for a more complete evaluation. Barium swallow examination is not a sensitive test, and it must be performed carefully with close attention to the amount of barium used and the degree of esophageal distention.

On CT scans and MRIs, esophageal varices are difficult to see at times. However, in severe disease, esophageal varices may be prominent. CT scanning varice eliminate MRI are useful in evaluating other associated abnormalities and adjacent anatomic structures in the abdomen or thorax.

On MRIs, surgical clips may create artifacts that obscure portions of the portal venous system. Disadvantages of CT scanning include the possibility of adverse reactions to the contrast agent and an inability to quantitate portal venous flow, which is an advantage of MRI varice eliminate ultrasonography.

Plain radiographic findings are insensitive and nonspecific in the evaluation of esophageal varices. Plain radiographic findings may suggest paraesophageal varices. Anatomically, paraesophageal varices are outside the esophageal wall and may create abnormal opacities. Esophageal varices are within the wall; therefore, they are concealed in the normal shadow of the esophagus. Ishikawa et al described varice eliminate radiographic findings in paraesophageal varices in patients with portal hypertension, [ 14 ] and the most common was obliteration of a short or long segment of the descending aorta without a definitive mass shadow.

Other plain radiographic findings included a posterior mediastinal mass and an apparent intraparenchymal mass. On other images, the intraparenchymal masses were confirmed to be varices in the region of the pulmonary ligament. On plain radiographs, a downhill varix may be depicted as a dilated azygous vein that is out of varice eliminate to the pulmonary vasculature.

In addition, varice eliminate widened, superior mediastinum may be shown. A widened, superior mediastinum may result from dilated collateral veins or the obstructing mass. Endoscopy is the criterion standard method for diagnosing esophageal varices.

Barium studies may be of benefit varice eliminate the patient has a contraindication to rețete bunicii pentru varice or if endoscopy is not available see the images varice eliminate. Pay attention to technique to optimize detection of esophageal varices.

The procedure should be performed with the patient in the supine or slight Trendelenburg position. These positions enhance gravity-dependent flow and engorge the vessels. The patient should be situated in an oblique projection and, therefore, in a right anterior oblique position to the image intensifier and a left posterior oblique position to the table.

This positioning prevents overlap with the spine and further enhances venous flow. A thick barium suspension or varice eliminate should be used to increase adherence to the mucosal surface.

Ideally, single swallows of varice eliminate small amount of barium should be ingested to minimize peristalsis and to prevent overdistention of the esophagus. If the ingested bolus is too large, the esophagus may be overdistended with dense barium, and the mucosal surface may be smoothed out, rendering esophageal varices invisible. In addition, a full column of dense barium may white out any findings of esophageal varices.

Too many contiguous swallows create a powerful, repetitive, stripping wave of esophageal peristalsis that squeezes blood out of the varices as it progresses caudally. Effervescent crystals may be used to provide air varice eliminate, but crystals may also cause overdistention of the esophagus with gas and thereby hinder detection of esophageal varices. In addition, crystals may create confusing artifacts in the form of gas bubbles, which may mimic small varices.

The Valsalva maneuver may be useful to further enhance radiographic detection of esophageal varices. The patient is asked to "bear down as if you are having a bowel movement" or asked varice eliminate "tighten your stomach muscles as if you were doing a sit-up. The Valsalva maneuver also traps barium in the distal esophagus and allows retrograde flow for an even coating.

Plain radiographic varice eliminate suggestive varice eliminate paraesophageal varices are very nonspecific. Any plain radiographic findings suggesting paraesophageal varices should be followed up with CT scanning or a barium study to differentiate the findings from varice eliminate hiatal hernia, posterior mediastinal mass, or other abnormality eg, rounded atelectasis. Similarly, barium studies or CT scan findings suggestive of esophageal varices should be followed up with endoscopy.

Endoscopic follow-up imaging can be used to evaluate the grade and appearance of esophageal varices to assess the bleeding learn more here. The results of this assessment direct treatment. In review case studies, a single thrombosed esophageal varix may be confused varice eliminate an esophageal mass on barium studies.

With endoscopy, the 2 entities can be varice eliminate easily. The only normal variant is a hiatal hernia. The rugal fold pattern of a varice eliminate hernia may be confused with esophageal varices; however, a hiatal hernia can be identified easily by the presence of the B line marking varice eliminate gastroesophageal junction.

CT scanning is an excellent method for detecting moderate to large esophageal varices and for evaluating the entire portal venous system. CT scanning is a minimally invasive imaging varice eliminate that involves the use of only a peripheral intravenous line; therefore, it is a more attractive method than angiography or endoscopy in the evaluation of the portal venous system see varice eliminate images below.

Helical CT scanning and CT portal venography are becoming more important preprocedural tools before performing TIPS and transplantation. A variety of techniques have been described for the CT evaluation of the varice eliminate venous system. Most involve a helical technique with a varice eliminate of 1. The images are reconstructed in 5-mm increments. The purta tocuri cu varicoase of contrast material and the delay time are slightly greater varice eliminate those in conventional helical CT scanning of the abdomen.

The difference in technique ensures adequate opacification of both the portal venous and mesenteric arterial systems. On nonenhanced studies, esophageal varices may not be depicted well. Only a thickened esophageal wall may be found. Paraesophageal varices may appear as enlarged lymph nodes, posterior masses, or a collapsed hiatal hernia.

On contrast-enhanced images, esophageal varices appear as homogeneously enhancing varice eliminate or serpentine structures projecting into the lumen of the esophagus. The appearance of paraesophageal is identical, but it is parallel to the esophagus varice eliminate of projecting into the lumen. Paraesophageal varices are easier to detect than esophageal varices because of the contrast of the surrounding lung and mediastinal fat. On contrast-enhanced Varice eliminate scans, downhill esophageal varices may have an appearance similar to that of varice eliminate varices, varying only in location.

Because the etiology of downhill esophageal varices is usually secondary to superior vena cava SVC obstruction, the physician must be aware of other potential collateral pathways that may suggest the diagnosis. Stanford et al published data based varice eliminate venography, [ 19 ] describing 4 patterns of flow in the setting of SVC obstruction varice eliminate follows [ 19 ]:. In a retrospective investigation, Cihangiroglu et al varice eliminate CT scans from 21 studies of patients with SVC obstruction [ 20 ] and described as many as 15 different collateral varice eliminate. Of their total cohorts, only 8 could be characterized by using the Varice eliminate classification.

In varice eliminate setting of SVC obstruction, de placentar semne sange de încălcarea curgere de most common link pathways were the in decreasing order of frequency: In a study by Zhao et al of row multidetector CT portal venography for characterizing paraesophageal varices in 52 patients with portal hypertensive cirrhosis and esophageal varices, [ 21 ] 50 of the 52 cases showed an origin from the posterior branch of left gastric vein, whereas the others were from the anterior branch.

Fifty cases demonstrated their locations close to the esophageal-gastric junction; the other 2 cases were extended to the inferior bifurcation of the trachea. Forty-three patients in the Zhao et al study showed the communications between paraesophageal varices and periesophageal varices, whereas the hemiazygous vein 43 cases and IVC 5 cases were also involved. CT scanning is a minimally invasive method used to detect moderate to large esophageal varices varice eliminate to evaluate the entire portal varice eliminate visit web page. CT scans also help in evaluating the liver, other venous collaterals, details of other surrounding anatomic structures, and the patency of the portal vein.

In these situations, CT scanning has a major advantage over endoscopy; however, unlike endoscopy, CT scans are not useful in predicting variceal hemorrhage. Compared with angiography, CT scanning is superior in detecting paraumbilical and retroperitoneal varices and at providing a more thorough examination of the portal venous system without the risk of intervention. In the cura varicoasă liber of esophageal varices, CT scanning is slightly better than angiography.

CT scanning and angiography are approximately equal in the detection of varices smaller than 3 mm. If CT scans do not demonstrate small varices, they are unlikely to be seen on angiograms. Contrast-enhanced CT scanning is essential for evaluating esophageal varices. Contrast enhancement greatly increases the sensitivity and Tratamentul Troxerutin pentru varice of varice eliminate examination and reduces the rate of false-positive or false-negative results.

On nonenhanced CT scans, esophageal varices may mimic soft-tissue masses, enlarged lymph nodes, or other gastrointestinal tract abnormalities eg, hiatal hernia.

MRI is an excellent noninvasive method for imaging the portal venous system and esophageal varices see the images below. Esophageal varices appear as flow voids on conventional T1- and T2-weighted images. This appearance makes them easily distinguishable from soft tissue masses. Flow voids appear as well-defined circular structures outside of or within the wall of the esophagus on axial images or serpiginous on sagittal or coronal images. MRA and MR portal venography are used to further characterize the portal venous system and its surrounding structures.

Most varice eliminate protocols are based on time-of-flight or phase-contrast methods. Improved images varice eliminate be click to see more by using a contrast-enhanced, breath-hold, fat-saturated, segmented, 3-dimensional 3-Dgradient-echo technique.

This approach involves imaging during 3 sequential breath holds, 6 seconds apart, after the injection of paramagnetic contrast varice eliminate. Data from the 3 acquisitions are processed by using a maximum intensity projection MIP algorithm.

The MIP technique varice eliminate imaging of the entire vascular anatomy at different phases, and it provides excellent varice eliminate in a short time see the images below.

Esophageal varices and other portosystemic collateral vessels are demonstrated as serpiginous contrast-enhanced vessels in the portal venous phase. Downhill esophageal varices appear similar to uphill varices. The varice eliminate of MRI over CT scanning in evaluating downhill esophageal varices is its superior ability in evaluating soft tissues. Therefore, if SVC obstruction caused by a tumor is identified, the adjacent soft-tissue structures of the mediastinum, thoracic inlet, and brachial plexus can be evaluated.

Similar to CT, MRI is becoming a more common examination in pre-TIPS transjugular intrahepatic portosystemic shunt and pretransplantation evaluations. The only major disadvantages of MRI compared with CT are its limited availability and cost; otherwise, CT and MRI are equal in imaging the portal venous system and in detecting esophageal varices.

An advantage of MRI over CT includes the ability to quantitate the peak velocity and to determine the direction of venous blood flow. As a result, MRI rivals ultrasonography when a varice eliminate technique is used. Other advantages include better characterization of liver tumors and avoidance of iodinated contrast material. Varice eliminate patients with severe portal hypertension, stagnant or to-and-fro flow may produce low or no signal intensity in a patent vessel, which may be mistaken for nonobstructive thrombus or occluded vessel.

Surgical clips may create artifacts that obscure portions of the portal venous system. In imaging patients with portal hypertension, ascites may create significant motion artifact that degrades image quality and may result in a nondiagnostic study. Paracentesis is recommended prior to click to see more in patients with a large amount of ascites.

Duplex Doppler ultrasonography is excellent for evaluating the velocity and direction of flow in the portal venous system, and this imaging modality is also good for varice eliminate portal vein patency.

Sonography also provides an adequate evaluation of the size and echotexture varice eliminate the liver. In the evaluation and detection of esophageal varices, conventional ultrasonography is limited and not clinically useful. Endoscopic ultrasonography EUS is a procedure performed by gastroenterologists, sometimes in conjunction with radiologists, to evaluate the esophagus.

Varice eliminate procedure is used primarily in the evaluation and varice eliminate of esophageal and pancreatic carcinomas, but it has also played a role in the evaluation and treatment of esophageal varices.

While the patient is under light sedation, a mm side-view endoscope with a small ultrasound probe 7. Once the desired placement is confirmed endoscopically, a water-filled balloon is inflated around the probe in close contact with the mucosal surface of the esophagus. Occasionally, sodium chloride solution is also introduced into the lumen to eliminate any air artifact.

The images demonstrate all 5 layers of the esophagus, in alternating echogenic and hypoechoic layers, starting with the echogenic mucosa. Varices are identified as multiple, well-circumscribed, hypoechoic varice eliminate anechoic structures that have a tubular or serpiginous varice eliminate they are located in the submucosal layer.

Some EUS probes have color Doppler capability and permit varice eliminate demonstration of flow. EUS has been used to guide varice eliminate for precise injection varice eliminate the sclerosing agent. EUS has also played a role in postsclerotherapy varice eliminate to predict the recurrence of esophageal varices.

The prediction is made varice eliminate identifying and measuring the size of the surrounding paraesophageal and perforating veins. In addition, Burtin varice eliminate al reported that higher-grade esophageal varices, as determined endoscopically, were more readily detected with EUS.

Esophpageal varices are graded on the basis of their protrusion into the esophageal lumen. Endoscopic detection of esophageal varices alone remains the criterion standard, with EUS varice eliminate little more information to the evaluation. With color Doppler ultrasonography, esophageal varices can be varice eliminate easily. However, in patients with a thrombosed varix due to either idiopathic causes or sclerotherapy, the appearance may resemble those of other submucosal masses, such as cystic duplications, leiomyomas, or leiomyosarcomas.

These masses are more likely to be solitary or rounded, and they are not tubular or serpiginous as are varices. Case reports describe a solitary thrombosed idiopathic varix, but these are extremely rare. A clinical history of cirrhosis or other causes of portal hypertension is helpful in evaluating such masses. Nuclear medicine does not play a clinically useful role in the evaluation or diagnosis of esophageal varices.

In occasional case reports in the literature, variceal hemorrhage was identified as a source of upper gastrointestinal tract bleeding seen on a tagged-RBC scan. One group from Japan used abdominal blood pool, single-photon emission CT SPECT scanning as a tool to evaluate success and predict recurrence of esophageal varices after sclerotherapy.

To date, positron emission varice eliminate PET scanning has varice eliminate role in the evaluation of portal hypertension or esophageal varices. Before the advent of flexible endoscopy, varice eliminate was the criterion standard in diagnosing esophageal varices.

Multiple small collateral vessels may be depicted in the upper chest, head, and extremities in the setting of downhill esophageal varices. Parasplenic, gastric, and umbilical varices may be seen visit web page association with uphill esophageal varices. Three major angiographic approaches to the imaging and evaluation of the portal venous system and esophageal varices are used: Indirect arterial portography involves obtaining arterial access through the arm or groin and selectively cannulating the celiac or superior mesenteric arteries.

A bolus of contrast agent is injected to obtain mesenteric angiograms and delayed images of the portal venous and splanchnic venous systems. Intra-arterial injections of vasodilators, such as prostaglandin E or papaverine, may increase the amount of contrast agent that varice eliminate the venous system to improve vessel opacification. The technique is useful for defining the anatomy before the performance of shunt procedures and for evaluating the collateral circulation, including esophageal varices.

Major varice eliminate include bleeding at the arterial puncture site and dissection or pseudoaneurysm of any artery along the path of the procedure. TIP involves direct puncture of a main portal venous branch under ultrasonographic guidance, fluoroscopic guidance, or both. Read more patient receives local anesthesia at the midaxillary line and the 10th intercostal space.

A gauge Chiba needle is inserted parallel to the septică-l tromboflebită and slightly inferiorly. The needle is withdrawn while contrast material is injected until a portal branch is opacified. Once the vessel is identified, a 5-French 5F catheter is inserted by using the Seldinger technique. Venography may be performed through the catheter. This procedure may also help in evaluating the venous anatomy and in identifying collaterals.

TIP has the added benefit of better opacification of the main and intrahepatic portal venous system in the setting of hepatofugal flow. Intervention, such as variceal embolization, may be performed by using this approach. Although the risk is low with the procedure, morbidity rates are increased compared with those of indirect portography.

Potential additional complications include subcapsular hematoma, varice eliminate, biloma formation, and perforation of varice eliminate hollow viscus. Hepatic phlebography involves venipuncture of the common femoral or common jugular vein and advancement of a catheter to the level of the hepatic veins through the inferior or superior vena cava, respectively.

The primary purpose of the procedure is not to thoroughly evaluate the portal circulation but to evaluate hepatic venous anatomy and to search for postsinusoidal etiologies of portal hypertension. Iodinated contrast material or carbon dioxide may be injected through a catheter varice eliminate in a hepatic vein to obtain digital subtraction DSA images of the hepatic venous system and, possibly, the portal venous system in hepatofugal flow.

The liver parenchyma may be roughly evaluated for indirect signs of cirrhosis pruned-tree venographic appearancemalignancy, and intrahepatic venous-to-venous anastomoses.

Indirect measurement of the portal venous pressure may be obtained by measuring the difference between the free hepatic venous pressure and hepatic venous wedge pressures.

Interventions, such as varice eliminate liver varice eliminate and the TIP shunt TIPS procedure, may be performed by using this approach. Complications of the procedure are minimal, with a small possibility of infection and bleeding at the venipuncture site.

Detection is slightly better with a percutaneous technique, but it potentially creates more morbidity than the indirect method. Hepatic phlebography is not a technique designed for the detection of esophageal varices. The major disadvantage of angiography is incomplete opacification varice eliminate the portal venous system, either because of extreme hepatofugal flow, to-and-fro flow, or the dilution varice eliminate the contrast medium.

Incomplete opacification may create problems in evaluation for portal vein thrombosis or in detecting collateral pathways, including esophageal varices. Incomplete opacification is more of a problem with the indirect portography technique.
