Abstract

To clarify the outcome of surgical reconstruction for renal artery in Takayasu arteritis-induced renal artery stenosis (TARAS). A retrospective chart review was conducted on 33 consecutive patients with TARAS, who underwent aortorenal bypass (ARB) with autologous saphenous vein graft. There were 9 male and 24 female patients, with a mean age of (25 ± 11) years. The effects on blood pressure and renal function were analyzed. Primary, primary assisted, and secondary patency rates were determined. The effects of various factors on primary patency rate were analyzed. All patients showed hypertension. The mean blood pressure was (175 ± 26)/(100 ± 19) mmHg (1 mmHg = 0.133 kPa). The mean antihypertensive dosage was (2.1 ± 0.6) defined daily dose (DDD). Seventeen patients showed intractable hypertension. Mean estimated glomerular filtration rate was (78 ± 5) ml/min. One patient was dialysis-dependent, and 3 patients were combined with congestive heart failure. ARB was performed for the 39 renal arteries, including 27 unilateral and 6 bilateral bypasses. Postoperative morbidity was 15.2%. All patients survived. During follow-up of mean (56 ± 18) months, two graft occlusions and four graft restenoses occurred. All graft restenoses were e...Continue Reading
