Preoperative knowledge of the presence of major venous anomalies facilitates the safe performance of aortic surgery. The purpose of the study was to estimate the incidence, as detected by abdominal computed tomography (CT), of major left renal vein anomalies related to the abdominal aorta in an adult population.
Seven hundred and fifty abdominal CT examinations were reviewed retrospectively for the presence of left renal vein anomalies. Eleven CT scans were excluded from the study because of technical or patient- -related factors. The course of the left renal vein was assessed on the CT slices to detect any anomalies.
Left renal vein anomaly was detected in 23 (3.1%) of 739 cases. Seventeen (2.3%) of them were a retro-aortic, and six (0.8%) of them were a circumaortic left renal vein.
It is important to detect left renal vein anomalies before retroperitoneal surgery or interventional procedures. These anomalies can be identified in routine abdominal CT examinations with a careful inspection.
术前了解主要静脉异常情况有助于主动脉手术的安全进行。本研究的目的是评估成人中通过腹部计算机断层扫描（CT）检测到的与腹主动脉相关的主要左肾静脉异常的发生率。
回顾性分析750例腹部CT检查，以确定是否存在左肾静脉异常。由于技术或与患者相关的因素，11例CT扫描被排除在研究之外。在CT切片上评估左肾静脉的走行，以检测任何异常。
在739例病例中，23例（3.1%）检测到左肾静脉异常。其中17例（2.3%）为主动脉后左肾静脉，6例（0.8%）为主动脉周围左肾静脉。
在腹膜后手术或介入操作前检测左肾静脉异常很重要。通过仔细检查，这些异常可在常规腹部CT检查中被识别。
