ABSTRACT
Background: With ever increasing load of liver disease on population of developed as well as developingcountries, it has become mandatory to have a detailed knowledge about hepatic arteries. Since adequate literatureregarding hepatic arteries and its variation e in people living in and around Eluru is not available, a study ofhepatic arteries ad its variation is carried out in our ASRAM medical college, Andhra Pradesh, India.Aims and objectives: To study the variations in the origin, course of right hepatic arteryMaterials and methods: This study was conducted in 60 embalmed adult cadavers of both sexes of age groupbetween 50 to 80 years. The common hepatic artery and its branch gastroduodenal artery were identified. Properhepatic artery in the hepatoduodenal ligament was traced and the relation of the common hepatic artery and theproper hepatic artery were noted. Origin of the RHA was traced and the presence of aberrant right hepaticarteries: (i) Replaced; (ii) Accessory were noted. To identify the presence of aberrant right hepatic arteries,abdominal aorta was exposed from the level of origin of the coeliac trunk to the level of origin of the inferiormesenteric artery.Results: In this study, the right hepatic artery originates from the proper hepatic artery in 24 (60%) specimens.Theaberrant, accessory and replaced right hepatic artery were found to be 20%, 12.5%, and 7.5% respectively. 5% ofspecimen showed caterpillar hump in right hepatic artery.Conclusion: Right hepatic artery is subject to anatomical variation in its origin and course. Because of anatomicvariations in the RHA, surgical injuries in the liver can occur even by the most experienced surgeon. A thoroughknowledge of the RHA anatomy is necessary while performing hepatic surgery and hepatic arteriography
ABSTRACT
Background and Aims: The thoracic duct is the major lymphatic duct in the human body, the variations in theorigin, course and termination of the thoracic duct are of great clinical importance during surgeries related tothe upper abdomen, posterior mediastinum and in cervical region, but still now a detailed study had not beendone in Andhra Pradesh state, it was decided to undertake this present study. Isolation of the thoracic duct andtracing the origin, course and termination were done to know more about it than already documented andthereby hoping to add more information to guide the radiologists and operating surgeons.Materials and methods: A total number of 45 cadavers were studied, of these 15 were female and 30 were malecadavers. The material consisted of adult cadavers between the ages of 42-81 from the dissection halls ofdepartment of anatomy of 3 different medical colleges in costal Andhra Pradesh.Results: The observations of the formation, course, length, vertebral levels, types of cisterna chili, and variationsin the termination in cervical region are documented in this study. Conclusion: The present findings showed agreat variability compare the previous studies. The findings noted in the present study regarding thoracic ducthad contributed to a better understanding of the anatomy of the thoracic duct and will prove definitely useful tosurgeons during surgical procedures related to the thoracic duct.
