主动脉狭窄时的胃肠道出血少见,出血时常不能明确诊断,普通放射学检查往往不能确定出血来源,应用肠系膜血管造影术能很好识别病损,通常损害限于右结肠内某一畸形的血管,但胃肠道其他部位也可发生血管发育不良。作者自1973年2月～1976年7月遇到5例典型主动脉狭窄伴下消化道反复大量出血患者,常规 X 线检查不能确诊,经肠系膜血管造影发现出血灶,4例在右结肠、1例在空肠处有血管畸形,全部病例作了右侧半结肠切除术或部分空肠切除术,术后随访均无再
Gastrointestinal bleeding in aortic stenosis rare bleeding often can not be diagnosed, the general radiological examination often can not determine the source of bleeding, the application of mesenteric angiography can well identify lesions, usually damage is limited to a deformity in the right colon of blood vessels , But other parts of the gastrointestinal tract can also occur vascular dysplasia. From February 1973 to July 1976, the authors encountered five patients with typical aortic stenosis complicated with repeated massive bleeding in the lower gastrointestinal tract. Conventional X-ray examination could not be confirmed. Hemorrhage was detected by mesenteric angiography. Four cases were found in the right colon, 1 Cases of vascular malformations in the jejunum, all cases were made on the right side of the half colon resection or partial jejunostomy, no follow-up postoperatively
