The increased pressure within the short gastric vein causes submucosal venous dilatation in gastric fundus.
PV, portal vein; SMV, superior mesenteric vein; CV, coronary vein; IMV, inferior mesenteric vein; SA, splenic artery; SV, splenic vein; LGEA, left gastroepiploic artery; LGEV, left gastroepiploic vein; SGA, short gastric artery; SGV, short gastric vein.
Thrombosed splenic vein with intact splenic artery induces hypertensive short gastric veins that can develop into varices in the gastric fundal submucosa.
After SAE, blood pressure in short gastric veins is decreased because the blood inflow to spleen is decreased.
We found that the pancreatic body and tail carcinomas were all located within the pancreatic capsule and no sign of metastasis, normal liver, splenomegaly, and short gastric vein
, gastroepiploic vein, gastric coronary vein dilated in gastrosplenic region.
