A Rare Variation of Hepatic Arteries (Michels Type IV): MDCT Angiographic Findings.
نویسندگان
چکیده
Recently, evaluation of hepatic artery variations has become increasingly important as liver transplantation from live donors gains in popular. Many diagnostic tools can be used to evaluate hepatic artery anatomy. Multi-detector computed tomography angiography (MDCTA) is one these methods. In this case report, we represent MDCTA findings of Michel type IV variation, which is a very rare condition of hepatic arteries.

Rare variations of hepatic arteries in association with variable origin of gastroduodenal artery found in multidetector computed tomography angiography.
Three rare anatomical variations were found during study on hepatic arterial vascularisation in multidetector computed tomography angiography. In the first described variation the common hepatic artery (CHA) arises from the celiac trunk (CTr) and supplies right hepatic lobe. The left lobe of the liver is supplied by aberrant left hepatic artery originating as a common trunk with the left gastri...

متن کاملSurgical relevance of liver arterial blood supply reconstruction by CT scan before a Whipple procedure.
Anatomical arterial vascular supply to the liver is varied [1]. Establishing the exact variant of this blood supply is important before pancreatic surgery. Identifying the exact vascular anatomy may help in decision-making during surgery. In 1955, Michels [2] published a study on hepatic arterial anatomy which was based on 200 autopsies. The classification was revised in 1966 by Michels and the...
متن کاملCase Report: Variation of the Gallbladder Vasculature Including Double Cystic Arteries
Acquaintance with the different anatomical variations of the arterial supply of the gallbladder is of great importance in hepatobiliary surgical procedures. A rare variation of the hepatobiliary arterial system was found during anatomical dissection of a female Iranian cadaver. Two cystic arteries were present, the first arising directly from the right hepatic artery and the second from the gas...
متن کاملMDCT angiography of right-sided aortic arch with aberrant left subclavian artery and duplicated left vertebral artery
Introduction Congenital variations of the aortic arch and its branches are commonly encountered in radiological practice [13]. A right-sided aortic arch (RAA) with an aberrant left subclavian artery (ALSA) is a rare variation that occurs in 0.05% of the population. The most common vertebral artery variation is the left vertebral artery (LVA) arising from the aortic arch with a reported prevelan...
