Long-term outcome after renovascular surgery. Comparison between thoracoretroperitoneal/saphenous vein and transabdominal/Dacron prosthesis bypass grafting.

The outcomes of 16 patients operated on for renovascular hypertension (RH) are analyzed. Eight had undergone surgery by the thoracoretroperitoneal approach with saphenous vein bypass grafting, and 8 by the transabdominal approach with a Dacron prosthesis. Distinct differences in favour of the former group were found after an average of 6 years of follow-up.
