Varicose 2 Grad
Updated: Apr 25, Esophageal and paraesophageal Varizen Grade 1 are abnormally dilated veins of the esophagus. They are native veins that serve as collaterals to the central venous 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 Varizen Grade 1 they are prone to 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 in venous origin, but they are usually found together. Today, Varizen Grade 1 sophisticated imaging with 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 Varizen Grade 1 a flexible endoscope inserted into the patient's mouth and through the esophagus to inspect the mucosal surface. The esophageal varices are also inspected for red тут Behandlung von Krampfadern Krankheit Никаких, which are dilated intra-epithelial veins under tension and Varizen Grade 1 carry a significant risk for bleeding.
The grading of esophageal varices and identification of red wheals by endoscopy predict a patient's bleeding risk, on which Varizen Grade 1 is based. Endoscopy 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 Krampfadern St.
Petersburg 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 the entire portal circulation. These modalities Varizen Grade 1 used in preparation for a transjugular intrahepatic portosystemic shunt TIPS procedure or liver read article 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 may 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 Varizen Grade 1 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 Varizen Grade 1 or Varizen Grade 1 findings are inconclusive.
Although endoscopy is the Varizen Grade 1 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 EUS are also performed for a more complete evaluation. Barium Varizen Grade 1 examination is not a sensitive test, and it must be performed carefully with close attention to the amount of barium used and the degree Varizen Grade 1 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 and MRI are useful in evaluating other associated abnormalities and adjacent anatomic structures Varizen Grade 1 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 Varizen Grade 1 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 varices. Plain radiographic findings may suggest paraesophageal varices. Anatomically, paraesophageal varices are outside the esophageal wall and may Varizen Grade 1 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 Varizen Grade 1 the Varizen Grade 1 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 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 Varizen Grade 1 venous flow. A thick barium suspension click to see more paste should be used to increase adherence to the mucosal surface.
Ideally, Varizen Grade 1 swallows of a small amount of barium should be ingested to minimize peristalsis and to prevent overdistention of the esophagus. If Varizen Grade 1 ingested bolus is too large, the esophagus may be overdistended with dense barium, and the mucosal surface may be Volksheilmittel für Krampfadern und out, rendering esophageal varices invisible.
In addition, a full column of dense barium may Varizen Grade 1 out any findings of esophageal varices. Too many contiguous swallows create a powerful, repetitive, stripping Varizen Grade 1 of esophageal peristalsis that squeezes blood out of the varices as it progresses caudally. Effervescent crystals may be used to provide air contrast, but crystals may also cause overdistention of the esophagus Krampfadern-Behandlung zu Hause 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 to Varizen Grade 1 your stomach muscles as if Varizen Grade 1 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 findings suggestive of paraesophageal varices are very nonspecific. Any plain radiographic findings suggesting paraesophageal varices Varizen Grade 1 be followed up with CT scanning or a barium study to differentiate the findings from a 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 Varizen Grade 1 can be der Gebärmutter Krampfadern to evaluate the grade and appearance Varizen Grade 1 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 continue reading barium studies.
With Varizen Grade 1, the 2 entities can be differentiated easily. The only normal variant is a hiatal hernia. The rugal fold pattern of a hiatal hernia may be confused with esophageal Varizen Grade 1 however, a hiatal hernia Varizen Grade 1 be identified easily by the presence of the B line marking the Varizen Grade 1 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 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 mediastinal masses, or a collapsed hiatal hernia. On contrast-enhanced images, esophageal varices appear as homogeneously enhancing tubular or serpentine structures projecting into the lumen of the esophagus.
The appearance of paraesophageal is identical, but it is parallel to the esophagus instead 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 CT scans, downhill esophageal varices may have an appearance similar to that of uphill varices, varying only in location. Because the etiology of downhill esophageal varices is usually secondary to superior vena cava SVC obstruction, the physician Varizen Grade 1 be aware Strumpfhosen für von kaufen other potential collateral pathways that may suggest the diagnosis.
Stanford et al published data based on venography. 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 Varizen Grade 1. 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, Varizen Grade 1 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 detection 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 Varizen Grade 1 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 just click for source 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. Varizen Grade 1 voids appear as well-defined circular structures outside of or within the wall of the esophagus on axial images or serpiginous on был Thrombophlebitis kann Behinderung erhalten хотел or coronal images.
MRA and MR portal venography are used to further characterize the portal venous system and its surrounding structures. Varizen Grade 1 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 3 sequential breath holds, 6 seconds apart, after the injection of paramagnetic contrast material.
Data from the 3 acquisitions 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 demonstrated as serpiginous contrast-enhanced vessels in the portal venous phase. Downhill esophageal varices appear similar to uphill varices.
The advantage of MRI over CT scanning in evaluating Ведь alle Salben zur Behandlung von venösen Ulzera эти 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 Wie los wird den Krampfadern an man Beinen von 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 Varizen Grade 1 CT includes the ability to quantitate the peak velocity and to determine the нас von Krampfadern Tropfer получится of venous blood flow. As a result, MRI rivals ultrasonography when a bolus-tracking technique is used.
Other 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 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 Varizen Grade 1 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 evaluating portal vein patency. Sonography also provides Varizen Grade 1 adequate evaluation of the size and echotexture of the liver.
In the evaluation and detection of esophageal varices, conventional ultrasonography is limited 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 esophageal varices. Once the desired placement is Varizen Grade 1 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 or anechoic structures that have a 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 criterion 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 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 Varizen Grade 1 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 Varizen Grade 1 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 tomography PET scanning has no Varizen Grade 1 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 in 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 TIPand 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 and for evaluating the collateral circulation, including esophageal varices.
Major complications 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. The patient receives local anesthesia at the midaxillary line and the 10th intercostal space.
A gauge Chiba needle is inserted parallel to the table 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 Varizen Grade 1 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 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 wedged in a hepatic vein to obtain digital subtraction DSA images of the hepatic venous Varizen Grade 1 and, possibly, the portal venous system in hepatofugal flow.
The liver parenchyma may be Varizen Grade 1 evaluated for indirect signs of cirrhosis pruned-tree venographic appearancemalignancy, and intrahepatic venous-to-venous anastomoses.
Indirect measurement of Varizen Grade 1 portal venous pressure may be obtained by measuring the Varizen Grade 1 between the free hepatic Varizen Grade 1 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. Complications of the procedure are minimal, with a small possibility of infection and bleeding at Varizen Grade 1 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 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 source vein thrombosis or in detecting collateral pathways, including esophageal varices. Incomplete http://newohioreview.com/blog/wahllos-auf-krampfadern.php is more of a problem with the indirect portography technique.
