Abstract Variations of the testicular veins are relevant in clinical cases of varicocele and in other therapeutic and diagnostic procedures. We report herein on a unique variation of the left testicular vein observed in an adult male cadaver. The left testicular vein bifurcated to give rise to left and right branches which terminated by joining the left renal vein. There was also an oblique communication between the two branches of the left testicular vein. A slender communicating vein arose from the left branch of the left testicular vein and ascended upwards in front of the left renal vein and terminated into the left suprarenal vein. The right branch of the testicular vein received an unnamed adipose tributary from the side of the abdominal aorta. Awareness of these venous anomalies can help surgeons accurately ligate abnormal venous communications and avoid iatrogenic injuries and it is important for proper surgical management.

Purpose. Thorough understanding of biliary anatomy is required when performing surgical interventions in the hepatobiliary system. This study describes the anatomical variations of right bile ducts in terms of branching and drainage patterns, and determines their frequency. Methods. We studied 73 samples of cadaveric material, focusing on the relationship of the right anterior and posterior segmental branches, the way they form the right hepatic duct, and the main variations of their drainage pattern. Results. The anatomy of the right hepatic duct was typical in 65.75% of samples. Ectopic drainage of the right anterior duct into the common hepatic duct was found in 15.07% and triple confluence in 9.59%. Ectopic drainage of the right posterior duct into the common hepatic duct was discovered in 2.74% and ectopic drainage of the right posterior duct into the left hepatic duct in 4.11%. Ectopic drainage of the right anterior duct into the left hepatic ductal system and ectopic drainage of the right posterior duct into the cystic duct was found in 1.37%. Conclusion. The branching pattern of the right hepatic duct was atypical in 34.25% of cases. Thus, knowledge of the anatomical variations of the extrahepatic bile ducts is important in many surgical cases.

This case report pertains to a variant termination of the right testicular vein into a large lower tributary of the right renal vein, instead of opening into the inferior vena cava. Since the lower vein in which the right testicular vein opened did not join the inferior vena cava directly, therefore there is no real duplication of the right renal vein which has been found in some previous case reports. The right renal vein had its normal termination into the inferior vena cava. Embryological explanation of the anomalous termination of the right testicular vein has been given.Journal of Universal College of Medical Sciences (2016) Vol.04 No.01 Issue 13, Page: 36-37

Developmental venous anomalies (DVA) drain normal neural tissue and are mostly discovered incidentally. We describe a young patient with a left hemisphere superficial to deep DVA and right hemisphere venous outflow restriction presenting with a seizure. The right hemisphere drainage variation is not typical of a DVA but represents another drainage pattern on the border of normality.

Abstract Background and aims : The development of the renal veins is a complex process with many possible alternative patterns of formation. Variations of renal veins are usually clinically silent until discovered during venography, operation or autopsy. In the era of renal transplantation, a meticulous knowledge of anatomy and variational patterns of renal vein is mandatory. The present study is aimed at finding out the incidence of variations in the drainage pattern of renal vein and gonadal vein and to correlate its clinical and embryological significance. Materials and methods : Twenty cadavers (twelve males and eight females) of adult age procured from Mahatma Gandhi Medical College and Research Institute, Puducherry were included in the study. Renal and gonadal veins on both sides were dissected and the pattern of termination of the renal and gonadal veins were observed and studied on both sides. Results : Out of twenty cadavers, two male cadavers showed the presence of termination of right testicular vein into right renal vein and both right kidneys showed multiple right renal veins. In the remaining 18 cadavers both renal and gonadal veins terminated in normal pattern. Conclusion: In present study 10% incidence of variation of right testicular vein draining into right renal vein was found, with the associated presence of multiple renal veins. The knowledge of these variations would be of definite help to renal transplant surgeons and clinicians.

The macroscopic features of the venous drainage of the reproductive system of the male ostrich were studied in six pre-pubertal and three sexually mature and active birds. Each testis was drained by one to four testicular veins. The right testicular veins drained the right testis and epididymis and its appendix to the caudal vena cava and to the right common iliac vein, whereas the left testicular veins drained the left testis and epididymis and its appendix exclusively to the left common iliac vein. A number of variations in the drainage pattern based on the point of entry and number of testicular veins were observed. The cranial aspect of the testis was also linked to the caudal vena cava or common iliac vein via the adrenal veins. The cranial, middle and caudal segments of the ductus deferens (and ureter) were drained by the cranial, middle and caudal ureterodeferential veins respectively, to the caudal testicular veins, the caudal renal veins and pudendal / caudal part of the internal iliac veins. In some specimens, the caudal ureterodeferential veins also drained into the caudal mesenteric vein. The surface of the phallus was drained by tributaries of the pudendal vein. The basic pattern of venous drainage of the reproductive organs of the male ostrich was generally similar to that described for the domestic fowl. However, important differences, including the partial fusion of the caudal renal veins, drainage of the cranial aspect of the testes via the adrenal veins, drainage of the caudal ureterodeferential veins into the caudal mesenteric vein and the presence of veins draining the surface of the phallus, were observed. Although significant, these differences may simply reflect variations in the normal pattern of venous drainage of the reproductive tract of birds which could be verified by studying more specimens and more species.
