ABSTRACT
The knowledge of vascular variations, like other anatomical variations, is important during the operative, diagnostic and endovascular procedures in abdomen. This report describes variations in the celiac trunk and abnormal entry of hepatic arteries into the liver as found during routine dissection in approximately 65 years old female cadaver. The celiac trunk was two inches long and gave 2 inferior phrenic arteries, a left gastric artery, and then bifurcated into a splenic and a common hepatic artery. The common hepatic artery gave rise to left hepatic artery, which entered the liver through fissure for ligamentum venosum. The common hepatic artery then divided into right hepatic and gastroduodenal arteries. The cystic artery was a branch of the left hepatic artery. The porta hepatis of the liver was situated on the right side of the caudate lobe.The knowledge of variation reported here is important during endovascular procedures, cholecystectomy and liver transplantation from the living donors (Fig. 2, Ref. 18).

Although variations in the attachments of the lumbrical muscles have been commonly reported, these have been seen mainly in the Caucasian population. The present study has been undertaken in South Indian population. The upper extremities of 24 South Indian (20 male and four female) cadavers were examined. Three instances of variant origins of the lumbrical muscles (two instances of the second and one of the first lumbrical) were seen. The muscles were unusually long extending to the level of the proximal border of the flexor retinaculum and in two of the cases it was taking origin from the flexor digitorum profundus tendon and its accessory belly. In one case it was taking origin from the flexor digitorum profundus and superficialis tendons. An anomalous origin of the lumbrical from muscles in the forearm has the potential to cause compression of the median nerve in the carpal tunnel.
