The application of prostaglandin E1 indirect portal vein angiography and color Doppler ultrasound in patients with post-devascularization portal hypertension.

The selection of proper treatment is based on identification of the causes of massive hemorrhage of gastrointestinal tract after pericardial devascularization. The combined use of prostaglandin E1 indirect portal vein angiography, DSA of celiac artery and color Doppler can provide detailed information about portal vein system, including the presence of embolism, spongioid changes and devascularization of left gastric vein and left gastric artery and the direction of blood flow. If these techniques failed to reveal the causes of digestive tract bleeding, the endoscopy may show lesions of gastric mucosa, which could be accountable for the bleeding.
