Posttransplant renal artery stenosis: angiographic study in 32 children

Renal artery stenosis was identified in 32 children who either developed or had an exacerbation of hypertension after renal transplantation. One child developed renal artery stenosis in two sequential transplants. Renal artery stenosis occurred only in those patients who received transplants from cadavers. In 14 of the 15 patients with end-to-end renal artery anastomoses, the stenosis was at the anastomosis. In 14 of the 18 patients with end-to-side anastomoses, the stenosis was distal to the anastomosis.
