Garbani Ch. 8 Flashcards
"Testing Hepatoportal Circulation"
TIPS -
Transjugular Intrahepatic Portosystemic Shunt
portal hypertension results from…..
increased pressure in the portal venous system to the liver
Portal hypertension impedes flow from……….from entering the liver
splanchnic or digestive system
Main reason for hypertension?
cirrhosis
cirrhosis is characterized by portal venous pressure of at least…………….
10-12 mm Hg
normal is less than 5 mm Hg
normal portal venous pressure
less than 5 mm Hg
Varices around stomach and esophagus may lead to…
massive hemorrhage
Treatment of choice for reoccurring bleeding disorders
TIPS
What can cause prehepatic portal hypertension? (6)
- congenital narrowing aka atresia (of portal veins)
- thrombosis (of portal veins)
- compression (of portal veins)
- arteriovenous malformations (in parenchyma)
- thrombosis (of splenic vein)
- splenomegaly
What can cause hepatic portal hypertension? (4)
- cirrhosis (from liver fibrosis)
- Schistosomiasis (parasite)
- Chronic Hepatitis
- Tumors
What can cause posthepatic portal hypertension? (3)
- IVC occlusion
- Budd-Chiari syndrome
- some cardiac anomalies (from increased pressure in right atrium
thrombosed hepatic veins
Budd-Chiari syndrome
TIPS procedure is for….. (2)
alleviating portal hypertension (due to bleeding)
and
ascites (sometimes)
TIPS complications (4)
- stenosis (common), thrombosis, infection
- TIPS misplacement
- hepatic encephalopathy
- Infarction
accumulation of fluid within the peritoneal system
ascites
an enlarged, tortuous vein, artery, or lymphatic vessel.
varix / varices
an escape of blood from a ruptured blood vessel, especially when profuse (pouring)
hemorrhage
“blood” “bursting forth (of blood)”
local coagulation or clotting of the blood in a part of the circulatory system
thrombosis
