作者报道4例急性胰腺炎或慢性胰腺炎急性发作病人CT示单发性肠系膜上静脉(SMV)血栓。男3例,女1例。年龄35～54岁。全部扫描于团注射造影剂30～90s后进行,发现有SMV血栓后还作延迟扫描。胰腺和胰周围区域用3～5mm层厚。 4例SMV内血栓表现为SMV内的低密度充盈缺损,周围有明亮的边缘即环样表现,为血管壁增强所致。血栓限于SMV内,脾、门静脉没有血栓。2例3月后,另2例分别为1月和4年后随访CT扫描均示SMV内血栓溶解消失。4例CT在示有SMV内血栓的同时分别有胰周水肿所致的肺周低密度区;腹水和既往胰腺炎留下的胰尾圆形低密度区;慢性
The authors report four cases of acute pancreatitis or acute pancreatitis in patients with CT showed single superior mesenteric vein (SMV) thrombosis. 3 males and 1 female. Age 35 to 54 years old. All scans were performed 30 to 90 seconds after group injection of contrast medium and delayed scanning was found after SMV thrombus. Pancreas and pancreas around the area with 3 ~ 5mm layer thickness. Four cases of SMV thrombus showed SMV within the low-density filling defect, surrounded by a bright edge that ring-like performance, due to increased vascular wall. Thrombosis within SMV, spleen, portal vein no thrombus. Two cases after 3 months, the other two cases were followed up for 1 month and 4 years after CT scan showed thrombolytic disappearance of SMV. 4 cases of CT showed thrombus in SMV at the same time with peripancreatic edema caused by peritoneal low density area; ascites and pancreatitis left pancreatic tail circular low density area; chronic
