Abstract
From April 1979 to March 1981, percutaneous transluminal angioplasty was attempted in 27 patients with atherosclerotic renal artery stenosis. In 13 patients, percutaneous transluminal angioplasty was considered successful with a decrease in blood pressure and/or improvement in renal function. Dilation of the stenosed renal artery was not technically possible in 4 patients and was unsuccessful in 10. Eight patients required surgical intervention after percutaneous transluminal angioplasty, including 4 elective operations and 4 done on an emergency basis. Five patients sustained intimal tears of the renal artery during percutaneous transluminal angioplasty with intramural dissection and/or thrombosis. Continued multidisciplinary evaluation of percutaneous transluminal angioplasty in the treatment of renal artery stenosis is recommended.
