Venous variants and anomalies on routine abdominal multi-detector row CT

“…21- 23 Koc et al reported that the incidence of left IVC and double IVC in 1,120 patients who underwent routine abdominal MDCT was 0.2% and 0.2%, respectively. 21 Aljabri et al reported that the incidence of left IVC and double IVC was 0.17% and 0.39%, respectively, on contrast-enhanced CT during preoperative evaluation before aorto-iliac surgery. 22 In our study, the incidence of IVC anomalies with horseshoe kidney was 5.7%, which is higher than the incidence in patients without horseshoe kidney.…”

Background: Several cases of horseshoe kidney with anomalous inferior vena cava (IVC) have been described, but there have been no reports of the incidence and variation of anomalous IVC in patients with horseshoe kidneys detected using multidetector row computed tomography (MDCT). Methods and Results:105 patients with horseshoe kidneys were evaluated with MDCT and a variety of venous anomalies were identified in 30 patients (28.6%). Anatomical variations of the renal vein were identified in 24 patients (22.9%), which was no higher than the reported incidence in the general population. However, variations of the IVC were identified in 6 patients (5.7%), which was a higher incidence than expected to be found in the general population: 1 pre-isthmic IVC with retrocaval ureter, 2 double IVCs posterior to the horseshoe kidney, 2 left IVCs posterior to the horseshoe kidney, and 1 azygos continuation of the IVC. Conclusions:Horseshoe kidneys are frequently found in patients with other venous, and particularly IVC, anomalies, which should be evaluated using MDCT as part of treatment planning.

“…Some anatomic variations in the renal veins may be correlated with clinical symptoms, as is the case of pain in the pelvic varices or varicocele. Furthermore, this multiplicity is more common in women than in men, as demonstrated by Arslan et al, Karazincir et al and Koc et al [20][21][22]., Therefore, description of the anatomic variations of the renal veins is necessary with regard to investigating the effects of these variations on hemodynamics and renal function, particularly in cases of surgical interventions in the retroperitoneal space [2], [23].…”

Context: Variations in renal vascular morphology are relatively common and involve both the renal arteries and the renal veins. Presence of supernumerary vessels is the variation most frequently encountered. Knowledge of such findings is valuable for urologists with regard to kidney transplantation, nephrectomy, vascular anastomosis, selective catheterization and many other surgical procedures on the kidneys. Objective: To report on a case of duplication of the right renal vein and its clinical and surgical implications. Case report: In one dissected specimen from a male cadaver, the presence of two right renal veins parallel to each other was observed in a position anteroinferior to the right renal artery. One vein emerged from the upper portion of the renal hilum, while the other emerged from the lower portion of the hilum. The two veins drained separately into the inferior vena cava, and neither of them received any tributaries. Conclusion: Knowledge of these vascular variations is important for urologists, vascular surgeons and radiologists, given that performing angiography prior to surgical interventions in the retroperitoneal space avoids complications, especially with regard to kidney transplantation.
