A new technical alternative in the surgery for retroperitoneal fibrosis: the Gore-Tex surgical membrane

The case of a male patient with retroperitoneal fibrosis secondary to an abdominal aortic aneurysm which was surgically treated with success, is presented herein. What is considered technically new is the management of the ureters after surgical lysis. An expanded polytetrafluoroethylene Gore-Tex surgical membrane, initially developed for pericardial closure after open-heart surgery, was used to isolate the bifurcated aortofemoral graft from the duodenum and the ureters from the vascular prosthesis and surrounding retroperitoneal tissues. This is considered to be a simple and safe technique and a technical alternative when dealing with this complex situation. To date, there has been no other description of such a technique using this material. The potential value of this material to prevent reencasement in retroperitoneal fibrosis from other origins should be kept in mind.
