Abstract
Because renal venous variations possess potential hazards during abdominal aortic surgery or laparoscopic donor nephrectomy, the detailed preoperative evaluation of the renal vessels with angiography should be performed to avoid vascular injuries. We present multidetector row computed tomography (MDCT) findings of the retroaortic left renal vein (RLRV) with other vascular variations. Twenty-two patients with RLRV were evaluated with MDCT using multiplanar images, MIP images, and 3D volume rendering. The RLRVs with accessory renal vessels and other variant veins draining into the left renal vein were effectively evaluated in all patients. MDCT angiography is an effective technique for evaluating abdominal vessels, and it presents adequate images of renal vessels and vascular variations, which pose importance before abdominal surgery.
Highlights
Renal vessels may show many variations with respect to their origins and drainage patterns; these variations become important in surgical and endourologic procedures and vascular interventions
Amaç: Böbrek veni varyasyonları, abdominal aortik cerrahi veya laparoskopik donör nefrektomisi esnasında potansiyel tehlike taşıdığından dolayı, damar yaralanmalarını önlemek için böbrek damarlarının operasyon öncesi anjiografi ile değerlendirilmesi gerekir

Summary
Renal vessels may show many variations with respect to their origins and drainage patterns; these variations become important in surgical and endourologic procedures and vascular interventions. The most commonly encountered renal vascular variations are the numbers of the renal arteries [1], more uncommon variations are the renal vein variations with their numbers, course, origins, and drainage sites. These variations can be detected in modern imaging techniques. We present multidetector row computed tomography (MDCT) findings of the retroaortic left renal vein (RLRV) with other associated vascular variations
