The knowledge of variations in the superficial veins is of clinical importance for the anatomist, radiologists, clinical practitioners and surgeons in order to plan about the operative procedures. Usually cephalic vein drains into the axillary vein. In this case report study the left cephalic vein communicates with the left external jugular vein and made a common trunk at the superior surface of the clavicle, and then opened into the subclavian vein posterosuperior to the clavicle. The aim of this report was to discuss about the presence of an abnormal communication between external jugular and cephalic vein.

This case study reports a rare variation of the superior laryngeal artery (SLA), which is the principal arterial supply of the larynx. The knowledge of the arterial variations is essential for the surgeons to prevent blood loss and postoperative complications. During routine dissection of an adult male cadaver, a rare arterial variation in the SLA was seen. In this case, the SLA passed through the thyroid foramen. The present study provides significant information about the SLA. We hope that it helps describe the arterial bleeding that may happen during laryngeal surgery.

The sciatic nerve is a largest single nerve of the lumbosacral nervous plexus. This nerve innervates all muscles of the leg and foot as well as the flexor muscles of the knee joint. Many variations in the direction and relations of sciatic nerve were described. The current case report presented a thick septum situated posterior to the sciatic nerve and its branches spread throughout the back of the thigh. The well identification of such variations is necessary for surgeons to consider them while scheduling clinical interventions.

An unusual origin of the common interosseous artery is reported in the paper. During educational dissection of a 37-year-old male, a rare variation in the origin of common interosseous artery of the right upper limb was observed. The common interosseous artery directly separated from radial artery. The right anterior interosseous artery is continued from common interosseous artery. Anterior and posterior ulnar recurrent arteries arising from common interosseous artery were noted on the right side of upper limb. In the present case, the median artery was replaced with anterior interosseous artery. Additionally, the ulnar artery passed superficially on flexor digitorum superficialis. In the cadaver, there was no other arterial or muscular variation. The embryological interpretation of this variation may be attributed to arising of the artery as a result of modifications to the normal pattern of capillary vessel maintenance and regression. Regarding the above mentioned variations, practical medical experiences are necessary to identify the variations of arterial pattern of upper limb vessels.
