Updated: Apr 25, Esophageal and paraesophageal varices are abnormally dilated veins of the esophagus. They are native veins that serve as collaterals to the Probe Varizen venous circulation when flow through the portal venous system or superior vena cava SVC is obstructed. Esophageal Probe Varizen 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 Probe Varizen hemorrhage.
Paraesophageal varices are collateral veins beyond the adventitial surface of the esophagus that parallel intramural esophageal veins. Paraesophageal varices are less prone to hemorrhage. Esophageal and paraesophageal varices are slightly different Probe Varizen venous origin, but they are usually found Probe Varizen. Today, more sophisticated imaging Probe Varizen computed tomography CT scanning, magnetic resonance imaging MRImagnetic resonance angiography MRAand endoscopic ultrasonography EUS plays an important role in the evaluation of portal hypertension and esophageal varices.
The procedure involves using a flexible endoscope inserted into kaufen Strümpfe Krampfadern patient's mouth and through the esophagus to inspect the mucosal surface. The esophageal varices are also inspected for red wheals, which are dilated intra-epithelial veins under tension and which carry a significant risk Probe Varizen bleeding.
The grading of esophageal varices and identification of red wheals by endoscopy predict a patient's bleeding risk, on which treatment is based. Endoscopy is Probe Varizen 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 Probe Varizen and the entire portal circulation. These modalities are Probe Varizen in preparation for a transjugular intrahepatic portosystemic shunt TIPS procedure or liver transplantation and in evaluating for a specific etiology of esophageal Probe Varizen. 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 Probe Varizen specific as endoscopy. CT scanning and MRI may be used as alternative methods in making the diagnosis if Probe Varizen is contraindicated Probe Varizen, 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 have become equally sensitive and specific in 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 scanning or MRI findings are inconclusive. Although endoscopy is the criterion standard in diagnosing and grading esophageal varices, the anatomy outside of the esophageal mucosa cannot be evaluated with this technique.
Therefore, imaging modalities such as CT scanning, MRI, and Probe Varizen 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 Probe Varizen amount of barium used and the degree of esophageal distention. On CT scans and MRIs, esophageal varices Probe Varizen difficult to see at times. However, in severe disease, esophageal varices may be prominent.
CT scanning and MRI are useful in evaluating other associated Probe Varizen 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 and ultrasonography.
Plain radiographic findings are insensitive and nonspecific in the evaluation of esophageal Probe Varizen. Plain radiographic findings may suggest paraesophageal varices. Probe Varizen, 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 chest radiographic findings in paraesophageal varices in patients with portal hypertension. 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 proportion to the pulmonary vasculature.
In addition, a 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 if the patient has a contraindication to endoscopy or if endoscopy is not available see the images below.
Pay attention to technique to Probe Varizen 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 Probe Varizen. A thick barium suspension or paste should be used to increase adherence to the mucosal surface.
Ideally, single swallows of a small amount of barium should be ingested to Probe Varizen peristalsis and to prevent overdistention of the esophagus. If the ingested bolus is too large, the esophagus may Probe Varizen 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 Probe Varizen of esophageal peristalsis that squeezes blood Probe Varizen of the varices as it progresses caudally.
Effervescent crystals may be used to provide air contrast, but crystals may also Probe Varizen overdistention of the esophagus with gas and thereby hinder detection of esophageal Probe Varizen. 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 to "tighten your stomach muscles as if you were doing a sit-up.
The Valsalva maneuver also traps barium in Probe Varizen distal esophagus and allows retrograde flow for an even coating. Plain radiographic findings suggestive of paraesophageal varices are very nonspecific. Any plain radiographic findings suggesting paraesophageal varices should be followed up Diclofenac Thrombophlebitis CT scanning or a barium study to Probe Varizen the findings from a hiatal hernia, posterior mediastinal mass, or other abnormality eg, rounded atelectasis.
Similarly, barium studies or CT scan Probe Varizen 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 risk.
The results of this assessment direct treatment. In review case studies, a single thrombosed esophageal varix may be confused with an esophageal mass on barium studies. With endoscopy, the 2 entities can be differentiated easily. The only normal variant is a hiatal hernia. The rugal fold Probe Varizen of a hiatal hernia may be confused with esophageal varices; however, a hiatal hernia can be identified easily by the presence of the B line marking the 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 modality 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 the images below.
A variety of techniques have been described for the CT evaluation of the portal venous system. Most involve a helical technique with a pitch of 1. The images are reconstructed in 5-mm increments. The amount of contrast material and the delay time are slightly greater than those Probe Varizen conventional helical CT scanning of the abdomen. The difference in technique ensures adequate opacification of both the portal venous and mesenteric arterial systems.
Probe Varizen nonenhanced studies, Probe Varizen varices may not be depicted well. Only a thickened esophageal wall may be found. Paraesophageal varices may appear as enlarged lymph nodes, posterior mediastinal masses, or a collapsed hiatal hernia. On contrast-enhanced images, esophageal varices appear as homogeneously enhancing tubular or serpentine structures projecting into here lumen of the esophagus.
The appearance of paraesophageal is identical, but it is parallel to the esophagus instead Probe Varizen projecting into the lumen. Paraesophageal Probe Varizen are Probe Varizen to detect than esophageal varices because of the contrast of the surrounding lung and mediastinal fat.
On contrast-enhanced CT scans, downhill esophageal varices may have an appearance similar to that of uphill varices, varying only in Probe Varizen. Because the etiology of downhill esophageal varices is usually secondary to superior vena cava SVC obstruction, the physician must be Strümpfe Krampfadern mit Männer of other potential collateral pathways that may suggest the diagnosis.
Stanford et al published data based on Probe Varizen. Of their total cohorts, only 8 could be characterized by using the Stanford classification.
In the setting of SVC obstruction, the most common collateral pathways were the in decreasing order of frequency : 1 azygous vein, 2 thoracoepigastric vein, 3 mediastinal vein, and 4 internal mammary vein. 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. Fifty cases demonstrated their locations close to the esophageal-gastric junction; the other 2 cases were extended to the inferior bifurcation of the trachea.
CT scans also help in evaluating Probe Varizen liver, other venous Probe Varizen, 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 Probe Varizen 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 detection Probe Varizen esophageal varices, CT scanning is slightly better than angiography. CT scanning and angiography are approximately equal in the detection of Probe Varizen 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 specificity of the examination and reduces the rate of false-positive or false-negative results. On nonenhanced CT scans, esophageal varices may Krampfadern, der Arzt behandelt 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 Probe Varizen its surrounding structures. Improved images can be obtained by using a contrast-enhanced, breath-hold, fat-saturated, segmented, 3-dimensional 3-Dgradient-echo technique. This approach involves imaging during Probe Varizen sequential breath holds, 6 seconds apart, after the injection of paramagnetic contrast material. Data from the 3 Probe Varizen are processed by using a maximum intensity projection MIP algorithm.
The MIP technique provides imaging of the entire vascular anatomy at different phases, and it provides excellent resolution in a short time see the images below. Esophageal varices and other portosystemic collateral vessels are Probe Varizen as serpiginous contrast-enhanced vessels in Probe Varizen portal venous phase.
Downhill esophageal varices appear similar to uphill varices. The advantage of MRI over CT scanning in evaluating downhill esophageal varices is its superior ability in Probe Varizen soft tissues.
Therefore, if SVC Probe Varizen caused by a tumor is identified, the adjacent soft-tissue structures of the mediastinum, thoracic Probe Varizen, 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 Probe Varizen major Алистре Salbe zur Behandlung von Thrombophlebitis превосходное 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 bolus-tracking technique is used.
Probe Varizen advantages include better characterization of liver tumors and avoidance of iodinated contrast material. In patients with severe portal hypertension, stagnant or to-and-fro flow may produce low Probe Varizen no signal intensity in a patent vessel, which may be Probe Varizen 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 examination 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 Probe Varizen portal vein patency. Sonography also provides an adequate evaluation of the size and echotexture of the liver.
In the evaluation and detection of esophageal varices, conventional ultrasonography is Probe Varizen and not clinically useful.
The procedure is used primarily in the evaluation and staging of esophageal and pancreatic carcinomas, but it has also played a role in the evaluation and treatment of Probe Varizen varices. 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 Probe Varizen 5 layers of the esophagus, in alternating echogenic and hypoechoic layers, starting with the echogenic mucosa. Varices are identified as multiple, well-circumscribed, hypoechoic or anechoic structures that have go here tubular or serpiginous appearance; they are located in the submucosal layer.
Some EUS probes have color Doppler capability and permit the demonstration of flow. EUS has been used to guide sclerotherapy for precise injection of the sclerosing agent. EUS has also played a role in postsclerotherapy follow-up to predict the recurrence of esophageal varices. The prediction is made by identifying and measuring the size of the surrounding paraesophageal and perforating veins. In a study by Burtin et al of 58 patients with cirrhosis and 16 control subjects. In addition, Burtin et 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 Probe Varizen standard, with EUS adding little more information to the evaluation.
With color Doppler ultrasonography, esophageal varices can be identified easily. However, in patients with a thrombosed varix due to either idiopathic causes or Probe Varizen, the appearance may resemble those of other submucosal masses, such as Probe Varizen 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. 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 Probe Varizen used abdominal blood pool, single-photon emission CT SPECT scanning as a tool to evaluate success and predict recurrence http://newohioreview.com/blog/befreien-sie-sich-von-krampfadern-waehrend-der-schwangerschaft-zu-erhalten.php esophageal varices after sclerotherapy.
To date, positron emission tomography PET scanning has no role in the evaluation of portal hypertension or esophageal varices. Before the advent of flexible endoscopy, angiography was the criterion standard in diagnosing esophageal varices. Parasplenic, gastric, and umbilical varices may be seen Probe Varizen 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, percutaneous transhepatic portography Probe Varizenand hepatic phlebography.
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 reaches the venous system to improve vessel opacification.
The technique is useful for defining the anatomy before the performance of shunt procedures Probe Varizen for evaluating the collateral circulation, including esophageal varices. Major complications include Probe Varizen 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, Probe Varizen guidance, or both.
The patient receives local anesthesia at the midaxillary line and the 10th intercostal Probe Varizen. A gauge Chiba needle is inserted parallel to the table and slightly inferiorly. The needle is withdrawn while contrast material is injected continue reading 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 Probe Varizen setting of hepatofugal flow. Probe Varizen, 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, hemobilia, biloma formation, and perforation of a hollow viscus. Hepatic phlebography involves venipuncture of the common femoral or common jugular vein and advancement of a Probe Varizen to the level of the hepatic veins Probe Varizen 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 wedged 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 appearanceProbe Varizen, and intrahepatic venous-to-venous anastomoses. Indirect measurement of the portal venous pressure may be Probe Varizen by measuring the difference between the free hepatic Probe Varizen pressure and hepatic venous wedge pressures.
Interventions, such as transvenous liver biopsy and the TIP shunt TIPS procedure, may be performed by using this approach. Probe Varizen 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 Probe Varizen incomplete opacification of the portal venous system, either because of extreme hepatofugal flow, to-and-fro flow, or the dilution of the contrast medium. Incomplete opacification may create problems in evaluation for portal vein thrombosis or in detecting collateral pathways, including Probe Varizen varices.
Incomplete opacification is more of a problem with the indirect portography technique. Cotran RS, Kumar V, Collins T, eds. Robbins Pathologic Basis of Disease. Philadelphia, Pa: WB Saunders Http://newohioreview.com/blog/behandlung-von-krampfadern-kaluga.php Sherlock S, Dooley J.
