[Angioscopy as intraoperative outcome control after reconstructive surgery of the renal arteries: presentation of a...

Main reasons for obstruction of renal arteries are atherosclerosis and fibromuscular dysplasia. In our clinic transaortic renal endarterectomy and interposition of a vein segment are preferred for arterial reconstruction. The surveillance of the distal intimal ridge after blind transaortic endarterectomy is still an unsolved problem, and the distal anastomosis of a vein graft must be checked, as it is performed under difficult conditions, if the suture is done in situ. We introduce angioscopy as a means of intraoperative surveillance.
