What is Devascularization procedure?
Devascularization procedures aim to control bleeding from varices in the esophagogastric region. They do not control bleeding from ectopic varices, nor do they treat the underlying disease. However, splenectomy, which is part of most described devascularization procedures, can effectively treat hypersplenism.
What varices mean?
Varices are veins that are enlarged or swollen. The esophagus is the tube that connects the throat to the stomach.
What is a Rex shunt?
The Rex shunt is a potentially curative surgical procedure that reestablishes physiologic hepatopetal portal flow. It is typically accomplished by interposing a vascular conduit between the superior mesenteric vein to the still patent intrahepatic portal venous system.
Where are varices located?
Varices are large or swollen blood vessels, which can be located around the esophagus. The most common cause of esophageal varices is scarring of the liver. Varices may be small or large, and the bigger they are, the more serious they become.
What causes varices to bleed?
Cause of Bleeding Varices It’s often due to scarring of the liver, or cirrhosis. This increased pressure in the portal vein causes blood to be pushed away from the liver to smaller blood vessels, which are not able to handle the increased amount of blood.
What does BRTO stand for in radiology?
Balloon-occluded retrograde transvenous obliteration. Balloon-occluded retrograde transvenous obliteration (BRTO) is a technique used by interventional radiologists in the treatment of gastric varices, particularly those with prominent infra-diaphragmatic portosystemic venous shunts (e.g. gastro-renal and gastro-caval shunts).
What are the indications for BRTO in the treatment of variceal bleeding?
The primary indications for BRTO is gastric variceal bleeding (or potential bleeding) and refractory encephalopathy in the presence of a gastrorenal shunt.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The effectiveness of BRTO in controlling bleeding gastric varices is 91–100% in two studies evaluating 20 patients (N = 19/20, controlled: 95%)., The gastric
What is BRTO and what are the advantages and risks?
One of the greatest advantages of BRTO is its preservation of liver function. Moreover, the increase of blood flow in BRTO can also improve liver function in cases where the patient has cirrhosis (scarring of the liver). What are the risks? Procedure-related complications are minor and include bleeding and infection.
What is the difference between BRTO and Parto?
PARTO was first described by Gwon et al.5 and involves the use of a permanent vascular plug instead of a temporary occlusion balloon as in BRTO. The advantages of PARTO include decreased procedure time, decreased post-procedure monitoring and removes the risks associated with an indwelling balloon catheter, i.e. rupture.
