A case of ischaemic proctitis apparently caused by adventitial fibromuscular dysplasia of the superior rectal artery is reported and the results of a survey of 50 superior rectal and marginal arteries from post mortem and surgical cases are described. Abnormal musculature was demonstrated in varying degree in the adventitia of 28 of 50 asymptomatic patients. Our findings indicate that a spectrum of this vascular abnormality exists in the elderly which is rarely severe enough to contribute to symptomatic large bowel ischaemia.
报告了一例明显由直肠上动脉外膜纤维肌发育异常引起的缺血性直肠炎，并描述了对50例尸检和手术病例的直肠上动脉和边缘动脉的调查结果。在50例无症状患者中，有28例在外膜中显示出不同程度的异常肌肉组织。我们的研究结果表明，老年人中存在一系列这种血管异常，其严重程度很少足以导致有症状的大肠缺血。
