Hepatomesenteric trunk.

An hepatomesenteric trunk, formed by the common hepatic and superior mesenteric arteries, was found in a 50-year-old male cadaver. The left gastric and splenic arteries arose as a common trunk, the gastrosplenic trunk, from the abdominal aorta; no typical celiac trunk was present. In addition, the hepatomesenteric trunk passed posterior to the portal vein. A knowledge of variations of the common hepatic artery may be important in pancreaticoduodenectomy, as well as during hepatic artery infusion chemotherapy.

Double superior gemellus together with double piriformis and high division of the sciatic nerve.

We report a case with double superior gemellus and double piriformis mm. associated with the sciatic n. dividing high and passing between the two piriformis mm. in the same lower extremity. This abnormality has not previously been described in the literature. As many musculoskeletal structures may be involved in sciatica, the supernumerary superior gemelli and piriformis mm. may exert pressure on the sciatic n. and this should be taken into account by clinicians.

An anatomic study of the lateral femoral cutaneous nerve.

In this study, the course of the lateral femoral cutaneous n. was examined bilaterally in 22 cadavers. Seven of these 44 lateral femoral cutaneous nn. showed variations in their course, especially in their number of branches under the inguinal ligament. During operations where the lateral femoral cutaneous n. may be demaged or in its decompression surgery, the nerve is to be found under the inguinal ligament. 1.52 +/- 0.84 cm medial to the anterior superior iliac spine. This nerve can be found passing through the inguinal ligament in as many as four branches.

A complicated variation of the upper extremity vascularisation.

In the right upper extremity of a cadaver, the radial artery originated from the medial side of the brachial artery at a higher level than usual, which was 16.7 cm below the coracoid process. Then, this artery crossed over the brachial artery, passed to its lateral side and ran to the forearm in front of the aponeurosis of the biceps brachii muscle. The brachial artery ended 1 cm distal to the elbow joint by dividing into the ulnar, anterior interosseous and posterior interosseous arteries. The common interosseous artery was absent. As the radial and ulnar arteries may be used as microvascular donor or recipient vessels, a good knowledge of the arterial vascularisation of the upper extremity is essential in planning surgical and reconstructive procedures in this area. Secondly, the course of the radial artery in our cadaver may be mistaken for a vein and an intravenous injection in such an artery can result in the loss of the hand or forearm.
