门脉高压除常致食管胃底静脉曲张出血外,尚可引起十二指肠、膀胱、胆道等少见部位静脉曲张出血。后者称为异位静脉曲张出血,因其出血部位及方式不同,临床表现复杂,极易误诊误治。鉴此,特将有关文献作一综述。 1 消化系异位静脉曲张出血 1.1 十二指肠静脉曲张出血肝外门脉高压或门脉某一分支栓塞时,门脉血流可经胃结肠干和肠系膜上静脉的分支到胰十二指肠静脉,再经十二指肠后上静脉、幽门或胃网膜右静脉回流到门静脉,故易致十二指肠静脉曲张出血。王培英、宋建功
In addition to portal hypertension often caused by esophageal varices bleeding, can still cause duodenal, bladder, biliary tract and other rare parts of varicose bleeding. The latter is called ectopic varicose bleeding, because of the different parts and ways of bleeding, the clinical manifestations of complex, easy to misdiagnosis and mistreatment. In view of this, especially the literature review. A digestive system of ectopic varicose bleeding 1.1 Duodenal variceal extrahepatic portal hypertension or a branch of the portal vein embolization, portal blood flow through the stomach and the superior mesenteric vein of the branch to the pancreatic twelve Intestinal vein, and then through the duodenum after the upper veins, pyloric or gastro-omentum right venous return to the portal vein, it is easy to cause duodenal variceal bleeding.
