“…In the studied patients, supernumerary right renal veins were more frequent than the left ones. This is con- firmed by recent analysis of Zhu et al [20], who observed right renal vein variations in 19.2%, and left renal vein variations in 7.1% of their population, with supernumerary veins on the left found in 2.7% and 18.7% on the right side. Similarly, Janschek et al [7] report more common variations on the right side (23%) than on the left (6.7%).…”

Background: Left renal vein (LRV) variations occur in 0.8%-10.2% of the population.The most common LRV variations are retroaortic left renal vein (RLRV) and circumaortic left renal vein (CLRV). The purpose of this study is to determine the frequency of LRV variations in a large series on computed tomography (CT) and to investigate the association between LRV and malignancy development. examination of 12,341 (5,505 female, 6,836 male) patients was evaluated retrospectively in this study. Patients clinical and demographic data were recorded using the Hospital Information System.Results: LRV variations were detected in 314 (2.54%) of the 12,341 patients within the study. Of the 314 cases found to have LRV variations, 227 (1.84%) had RLRV, and 87 (0.70%) had CLRV. There was no statistical difference in total LRV variations (p = .083) and CLRV variation (p = .96) groups in terms of gender. However, the RLRV variation was found to be 1.32 times higher in males than in females (p = .039). Of the 314 patients with LRV variations, 73 (23.2%) had any sort of concomitant malignancy. Conclusions:A high incidence of malignancy was detected in patients with LRV variations. Of the LRV variations, RLRV variation is more common than CLRV variation. The presence of total LRV variations and CLRV variations is not associated with gender. Whereas the presence of RLRV variation is more common in the male gender.

“…Their relations with the aorta and the neighboring structures also may show variations. In a study by Zhu et al .,[1] variations of renal veins was found in 24.7% of cases. In this study, the variations of LRV were seen in 19.2%, and variations of right renal vein were seen in 1.7% of cases.…”

“…The renal veins may be more than one in number may receive abnormal tributaries or may have variant relations. [1] The renal arteries also may vary in their number, point of entry into the kidney, source of origin, and distribution. The inferior phrenic arteries are also variable in position.…”

Introduction:Knowledge of vascular variations near the kidney is of importance to many clinical disciplines such as nephrologists, radiologists, gastroenterologists, and general surgeons. Variant branches of the abdominal aorta and renal arteries are the victims of iatrogenic bleeding during surgery. We found multiple vascular variations in the upper part of the abdomen during our dissection classes.Methods:During the dissection classes of the abdomen for undergraduate medical students, we observed multiple vascular variations in the abdomen of an adult male cadaver. The vessels and surrounding viscera were cleaned using dissection instruments. Variations observed were photographed.Results:The right kidney had its hilum directed posteriorly. There were two right renal veins and a partially doubled left renal vein (LRV). The left suprarenal and gonadal veins drained into the upper LRV. There were two right renal arteries. Upper right renal artery gave origin to the right inferior phrenic and middle suprarenal arteries. There were two renal arteries on the left side also. The left upper renal artery gave a polar branch to the left kidney and divided into two branches before entering the kidney. The left inferior phrenic artery (IPA) gave two gastric branches to the fundus of the stomach.Conclusions:The variations noted by us are of tremendous surgical application. The variant vessels might get damaged during surgical procedures if the surgeons are not aware of these variations. The most important among the variations reported here is the gastric branch of the IPA, which has not been reported yet.
