portosystemic anastomoses Flashcards
esophagus anastomosis: clinical sign?
esophageal varices
esophagus anastomosis: portal and systemic vein?
portal: left gastric
systemic: esophageal (drains into azygos)
esophagus anastomosis: where does the blood drain?
from left gastric (portal) towards esophageal vein (systemic)
leads to esophageal varisces
umbilicus anastomosis: clinical sign?
caput medusae
umbilicus anastomosis: portal and systemic vein?
portal: paraumbilical
systemic: small epigastric veins (branches of inferior and superficial epigastric veins)
where are the small epigastric veins located?
anterior abdominal wall
anastomosis of paraumbilical and small epigastric veins: clinical sign?
abdominal varices
abdominal varisces is suggestive of which anastomosis?
paraumbilical (portal) and small epigastric veins (systemic)
esophageal varisces suggestive of which anastomosis?
umbilicus
rectum anastomosis: clinical sign?
anorectal varisces
umbilicus anastomosis: which direction does the blood drain?
(in case of portal hypertension)
from paraumbilical vein (portal) to small epigastric veins (systemic)
rectum anastomosis: portal and systemic veins?
portal: superior rectal
systemic: middle and inferior rectal
blood flows from from paraumbilical vein (portal) to small epigastric veins (systemic): clinical sign?
(when portal hypertension)
caput medusae
rectum anastomosis: blood flows where?
from superior rectal (portal) to middle and inferior rectal (systemic)
which direction does the blood flow in portosystemic anastomoses?
(in case of portal hypertension)
from portal to systemic
