The LFCN may emerge from the lateral border of the psoas major above or below the IC. The AC/AB ratio can help surgeons to find the LFCN in patients with different body types.

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.

During our routine dissection course for students we found a complex variation of the femoral artery on the left side of a 72-year-old male cadaver. The deep femoral artery was originating from the anterior aspect of the femoral artery; the inferior epigastric and the external pudendal arteries were arising from the deep femoral artery. Besides, the lateral circumflex femoral artery was arising from the lateral aspect of the femoral artery and distal to the origin of the deep femoral artery.

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.

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.
