脾靜脈血栓是胰臟炎一種少見的併發症，它常表現有胃靜脈瘤和脾腫大。脾靜脈血栓的診斷要靠血管攝影來確定，而都卜勒超音波檢查可以提供血管中血流速和血流量的測定。有些文獻報告在肝脾靜脈血栓中用都卜勒超音波來發現血栓。我們報告一個病例因高血酯症引起急性胰臟炎，在上消化道內視鏡中發現獨立胃靜脈瘤。因此我們用都卜勒超音波檢查，發現近端脾靜脈血流速為30.3 公分每秒但在遠端脾靜脈血流速降為17.1 公分每秒，其間差距為13.2 公分每秒，同時血管攝影檢查證實在脾門處有靜脈血栓。脾靜脈遠近端血流速差距似乎可以在胰臟炎病例中提供一種簡單的脾靜脈血栓篩檢方法。

Splenic vein thrombosis (SVT) is a rare complication of pancreatic disease, like pancreatitisor pancreatic cancer. Its common complications include gastric varices and splenomegaly. Adiagnosis of SVT should be kept in mind when a patient has acute or chronic pancreatitis, and adefinitive diagnosis is based on an angiographic examination. In some of the literature, Dopplerultrasound was mentioned in portosplenic vein thrombosis, but it was only related to thrombosisfound in the splenic vein or the absence of blood flow in the splenic vein.We report a case of SVTin the splenic hilum with isolated gastric varices due to acute pancreatitis, diagnosed by adecreased flow velocity of from 30.3 cm/s in the proximal splenic vein to 17.1 cm/s in the distalsplenic vein. The gradient between the proximal and distal splenic veins was 13.2 cm/s, which wasdefinitively proven by angiographic findings. The high gradient between the proximal and distalsplenic vein flow velocities may provide an easy method of screening for possible SVT in patientswith pancreatitis.
