Knowledge of variations of renal vessels is of utmost importance in retroperitoneal surgeries and kidney transplant surgeries. We report concurrent variations of the right renal vessels, observed in an adult male cadaver during dissection classes. The right kidney was supplied by three renal arteries, out of which two entered the kidney through the hilum and the other one entered through the lower pole of the kidney. There were five renal veins, emerging independently from the hilum and opening separately through five openings into the inferior vena cava. Among the veins, only one emerged anterior to the renal pelvis and the other four emerged behind it. Four of them terminated into the posterolateral aspect of the inferior vena cava, whereas one terminated into its anterior aspect. Fourth vein from above, received the right testicular vein. The renal hilum was clogged with the presence of seven vessels and renal pelvis.
Multiple venous variations at the abdominopelvic region: a case report

Knowledge of vascular variations of the abdominopelvic junction is of importance to surgeons, radiologists, orthopaedic surgeons and other medical disciplines. We report a rare combination of venous variations observed at the abdominopelvic junction of an adult male cadaver. The right common iliac vein was absent. The inferior vena cava was formed by the union of the right external iliac vein and the left common iliac vein. The right internal iliac vein was a tributary of the left common iliac vein. The left common iliac vein was larger than usual in size and its wall was adhered to the right common iliac artery. We discuss the functional, developmental and clinical issues related to the case.
Terminal bifurcation of the external jugular vein: a rare variation

Variations of external jugular vein are common. Here, we present a rare terminal bifurcation of the left external jugular vein. The left external jugular vein was formed by the union of entire retromandibular vein and posterior auricular vein. One inch above the clavicle, it bifurcated into medial and lateral divisions. The medial division terminated into the internal jugular vein and the lateral division terminated into the subclavian vein. Medial division received a common vein formed by the union of anterior jugular vein and an anonymous vein lying under the sternocleidomastoid muscle. The lateral division received a common vein formed by the union of suprascapular and transverse cervical veins. The knowledge about this variation could be useful to head and neck surgeons, radiologists and plastic surgeons.
Vascular variations of liver and gallbladder: a case report

Vascular variations in and around the porta hepatis are common. A sound knowledge of possible variations at these sites is vital for surgeons during laparoscopic cholecystectomy and surgical resection of the liver lobes. We report the case of several variations of the hepatic and cystic arteries in which, the common hepatic artery trifurcated into the gastroduodenal, right hepatic, and left hepatic arteries. The right gastric artery arose from the left hepatic artery and divided into a left and a right branch. The left branch entered the liver through the porta hepatis, while the right branch passed behind the common hepatic duct into the Calot's triangle, provided 2 branches to the gallbladder, and continued to supply the right hepatic lobe. Ligation of the right branch of the right hepatic artery in Calot's triangle during cholecystectomy could cause avascular necrosis of the liver segments it supplies.
