What is Devascularization?
Medical Definition of devascularization : loss of the blood supply to a bodily part due to destruction or obstruction of blood vessels.
What causes Esophagogastric varices?
Causes of esophageal varices include: Severe liver scarring (cirrhosis). A number of liver diseases — including hepatitis infection, alcoholic liver disease, fatty liver disease and a bile duct disorder called primary biliary cirrhosis — can result in cirrhosis. Blood clot (thrombosis).
What varices mean?
Varices are veins that are enlarged or swollen. The esophagus is the tube that connects the throat to the stomach.
What are Perigastric varices?
Gastric varices are dilated submucosal veins in the lining of the stomach, which can be a life-threatening cause of bleeding in the upper gastrointestinal tract. They are most commonly found in patients with portal hypertension, or elevated pressure in the portal vein system, which may be a complication of cirrhosis.
What is stepwise Devascularization?
Study design: Stepwise uterine devascularization was performed for 103 patients to control intractable postpartum hemorrhage not responding to classic management. This technique entails five successive steps, so if bleeding is not controlled by one step the next step is taken until bleeding stops.
What is Mesocaval shunt?
Mesocaval shunts are stent grafts placed by interventional radiologists between the mesenteric system, most often the superior mesenteric vein, and the inferior vena cava. This allows flow to bypass the congested hepatic system, reducing portal pressures.
How long can you live with portal hypertension?
These complications result from portal hypertension and/or from liver insufficiency. The survival of both stages is markedly different with compensated patients having a median survival time of over 12 years compared to decompensated patients who survive less than 2 years (1, 3).
How long can someone live with esophageal varices?
Varices recurred in 78 patients and rebled in 45 of these patients. Median follow-up was 32.3 months (mean, 42.1 months; range, 3–198.9 months). Cumulative overall survival by life-table analysis was 67%, 42%, and 26% at 1, 3, and 5 years, respectively.
What are Perisplenic varices?
PERISPLENIC VARICES AND SPLENORENAL AND SPLENOCAVAL/SPLENOAZYGOS SHUNTS. Splenic varices usually traverse the splenocolic ligament and are seen as dilated veins in the anteroinferior aspect of the spleen[20]. Perisplenic collaterals can communicate with the gastric veins.
What is the difference between gastric varices and esophageal varices?
The basic differences between esophageal and gastric varices are the layers in which the varicose veins form: the lamina propria mucosae and submucosa in the esophageal varices and the submucosa in gastric varices.
What is the medical definition of devascularization?
Medical Definition of devascularization. : loss of the blood supply to a bodily part due to destruction or obstruction of blood vessels.
What is the principle of devascularization procedures for variceal bleeding?
The principle of devascularization procedures for variceal bleeding is based on anatomic features. The coronary vein and gastric veins are anastomosed with tributaries of the superior vena cava by collateral channels in the submucosa of the esophagus, between the two muscular layers, and in the periesophageal region.
What is devascularization of esophagogastric veins?
Devascularization being a variceal-directed ablative surgery aims at obliteration of varices or disconnection of the esophagogastric veins from the hypertensive portal tributaries. From: Blumgart’s Surgery of the Liver, Biliary Tract and Pancreas, 2-Volume Set (Sixth Edition), 2017
What is the pathophysiology of ureter devascularization?
Devascularization of the ureter is a rare complication of routine hysterectomies and is more often encountered after extensive retroperitoneal dissection. Lymph node sampling and radical hysterectomy are the two most common offending surgeries.
