ABSTRACT
Multiple venous anomalies have been observed during dissection of the posterior abdominal wall in a 65-year-old, white male cadaver. The left testicular and suprarenal veins united inferior to the superior mesenteric artery, coursed anterior to the abdominal aorta and drained into the inferior vena cava (IVC). Further the left renal vein coursed retroaortically and divided into three branches. The superior branch coursed on the vertebral column and drained into the azygos vein while middle and inferior branches drained into the IVC. The right renal vein was double and both drained into the IVC separately. Due to implications for numerous therapeutical and diagnostic procedures in the retroperitoneal region knowledge of these variations could be useful for clinicians in its recognition and protection.

The variability of the arteries in the upper extremity is considerable. This case is a report of a trifurcation of the brachial artery that divided into radial, ulnar, and superior ulnar collateral arteries high in the arm; the length of the brachial artery was only 4.9 cm. Because the upper extremity is a frequent site of injury, various surgical and invasive procedures are performed in this region; consequently, it is of utmost importance to be aware of arterial variations. For some medical procedures, there may be an increased risk of complications because of variant vessels; however, for other procedures, they may be beneficial. In addition to presenting a detailed anatomic study of the case, the clinical significance of the variation has been addressed.

Variant sensory branches of the ulnar nerve were encountered during a routine dissection of the palmar aspects of a cadaver hand. The variant branches were distributed to the ulnar half of the index, ulnar half of the middle, and radial half of the ring fingers. The communicating branch between the superficial ulnar branch and the third common digital branch of the median nerve was absent. Distribution of the median nerve sensory branches was normal. The clinical significance of this variation is discussed.
