[Disease of branches of the renal artery. Choice of a revascularization procedure].

In situ versus extra-corporeal and microvascular reconstruction are discussed in relation to the treatment of renal branch artery disease. Ten cases are reported: 4 aneurysms, 1 atherosclerosis, 1 trauma, 1 embolism and 1 dissection. In three cases, the disease involved only the segmental artery branches and in seven cases both the main artery and the branches. An in situ procedure was performed in 5 cases and extra-corporeal surgery was necessary in 5 others. Four of the kidneys were iliac autotransplanted. Anatomical and immediate functional results were good in ten cases, but there was one postoperative death by heart failure due to a mitral disease. In our series extracorporeal and microvascular surgery were not routinely used for the treatment of renal artery branch disease. But these procedures can widen the indications for renal revascularisation, which then replaces medical treatment or a nephrectomy.
