Transplant renal artery stenosis: experience and comparative results between surgery and angioplasty.
One hundred thirty-eight patients with transplant renal artery stenosis (TRAS) were identified among 1200 patients undergoing renal transplantation in our university hospital. Severe systemic hypertension was the main symptom leading to a diagnosis of TRAS. Only 88 TRAS patients were given interventional treatment consisting of percutaneous angioplasty (PTA; n = 49) or surgical repair (SR; n = 39). The immediate success rate was 92.1% for SR and 69% for PTA. The long-term success rate was 81.5% for SR and 40.8% for PTA, with a follow-up period of 56.7 +/- 22.4 months (SR group) and 32 +/- 28.1 months (PTA group). PTA morbidity reached 28%, compared to 7.6% in the SR group. In spite of these results, we still favor PTA as a first line interventional treatment when TRAS is recent, linear, and distal and primary SR in cases of kinking and proximal TRAS.
