STUDY OF ABERRANT LEFT HEPATIC ARTERY FROM LEFT GASTRIC ARTERY AND ITS CLINICAL IMPORTANCE
Author: Suman Tiwari, Roopashree R., Padmavathi G., Varalakshmi K. L., Sangeeta M
Objectives: Variations of the hepatobiliary region are frequent and are of concern to the radiologists and gastroenterological surgeons. The variations reported in the literature are of several kinds such as accessory hepatic arteries, replaced hepatic arteries and additional branches. The present study describes the incidence of origin of aberrant left hepatic artery from left gastric artery and its clinical importance. Methods: 50 adult embalmed human cadavers of both the sexes were studied by dissection method at the Department of Anatomy, MVJ Medical College and other medical colleges in and around Bangalore. Results: In 4(8%) specimens, the aberrant left hepatic artery had its origin from left gastric artery. Out of the 4 specimens, the aberrant left hepatic branch was accessory in 3(6%) specimens and replaced in 1(2%) specimens. Conclusion: The knowledge about variations in the anatomy of subhepatic region is of immense significance to hepatobiliary surgeons since bleeding from aberrant vessels may increase the risk of intra-operative complications.
