ABSTRACT

Background: The liver is the largest gland in the body and has a wide variety of functions . It  receives  a double blood supply via the hepatic artery and the portal vein. The portal vein provides about  50% to 70% of the liver’s oxygenation and the hepatic artery gives about  30% to 50% oxygenation to the liver. Unlike portal vein anatomy, the hepatic arterial anatomy  is  extraordinarily variable . The incidence of aberrant hepatic artery is quite high . So the knowledge about hepatic vascular distribution and its variations is important to plan and to make trans arterial embolization therapy successful in the patients with metastatic liver tumors.

Aim : To find out the incidence of aberrant  arterial  variation  of  right hepatic artery  and  left hepatic artery  in  cadavers .

Materials and Methods: 60  adult specimens   from   cadavers   were   studied   by   using   conventional  dissection method   in  Institute of Anatomy , Madras  medical  college , Chennai .  Age & sex   of these cadavers were not determined.

Results:  4 specimens were showing both aberrant right hepatic artery and aberrant left hepatic artery. In addition to these, one specimen had an aberrant left hepatic artery only.  Middle hepatic artery  was  seen  in  three of these five specimens.

Conclusion : Knowledge about the aberrant hepatic arteries is important in the field of trans arterial embolization therapy  in  hepatic tumours .

Key words: Aberrant right hepatic artery, Aberrant left hepatic artery, Middle hepatic artery, Trans arterial embolization therapy.
