Abstract
INTRODUCTION: A good knowledge of arterial supply of the upper abdominal organ is very much essential for the surgeons, interventional radiologists and anatomists. During surgery, arterial variations cannot be ignored for the risk of ligating the wrong vessel or severing an essential artery resulting ischemia or bleeding. Identification of replaced arteries is more important because that may be the only blood supply for that region, ligation of which may lead to fatal necrosis. Knowledge of accessory arteries is also a must to anticipate the presence of an additional artery during surgery. The liver donor shortage and higher demand on liver transplantation lead to advanced liver surgical techniques for which the sound knowledge of arterial anatomy and its variation is very much mandatory. Sometimes the aberrant hepatic artery for the left lobe of the liver takes origin from the left gastric artery. Lack of awareness of this vessel may lead to severing of the only blood supply of the left lobe and lead to ischemic necrosis. AIM OF THE STUDY: The present study of the coeliac trunk and its branches in 50 specimens had been focused on to study the branching pattern of the coeliac trunk, presence of supernumery branches from coeliac trunk and its branches, presence of any aberrant vessels and to compare the findings with the results of the previous studies. MATERIAL AND METHODS: The study was conducted in the Institute of Anatomy, Madurai Medical College, Madurai. Sample Study: The study was done in 50 human cadaveric specimens. Of the 50 specimens, 22 were done in the dissection hall cadavers, 28 were collected from the post mortem among the Indian population irrespective of age and sex. Apart from these 50 specimens, a radiological study had been done in one patient. The radiological study was not included among the 50 specimens. Collection of Specimens: Post mortem specimens were collected from the Institute of Forensic Medicine, Madurai Medical College, Madurai. By an I-shaped incision extending from the suprasternal notch to pubic symphysis, anterior chest wall was opened. The heart and lungs were removed from the thorax. The thoracic aorta, thoracic part of inferior vena cava and oesophagus were tied, cut and removed proximally. Distally the abdominal aorta and inferior vena cava were tied and cut below the level of origin of the renal arteries and removed along with abdominal diaphragm, liver, spleen, stomach and pancreas in toto. The specimens were washed in the running water. 300 – 400 ml of 10%. CONCLUSION: The coeliac trunk took origin from the ventral surface of the aorta in all the 50 specimens. The various pattern of the trunk were normal hepatolienogastric trunk in 92%, lienogastric trunk in 2%, hepatolieno mesenteric trunk in 2%, coeliaco-colic trunk in 2%. In one specimen, coeliac trunk divided into common hepatic & splenic arteries, the left gastric artery took origin from the splenic artery. 96% of specimens had complete coeliac trunk and 4% had incomplete coeliac trunk. Tripod of Haller was seen in 38% of the specimens. The length ranged from 1.1 to 2.3 cm. The supernumery branches observed from the coeliac trunk were inferior phrenic artery in 32%, dorsal pancreatic artery in 12%, superior mesenteric artery in 2% and middle colic artery in 2%.
