Suzuki classification : a useful adjunct to michel and hiatt hepatic arterial classification systems
Journal Title: Journal of the Indian Medical Association - Year 2018, Vol 116, Issue 2
Abstract
Multidetector Computed Tomography (MDCT) allows non-invasive and accurate preoperative evaluation of hepatobiliary anatomy. Clinician is well versed with relevant hepatobiliary anatomy and can meticulously plan treatment in conveyance with radiologist. We highlight importance of Suzuki classification as a useful adjunct to Michel and Hiatt hepatic arterial classification systems. Hepatic arterial classification was first given in 1955 by Michel NA. Mitchell classification covered almost all hepatic artery variations except few like hepatic artery arising directly from aorta. Second clinically significant contribution was by Hiatt JR and coworkers who modified Michel classification system in 1994 and defined 6 types of hepatic artery variations. Hiatt JR simplified hepatic arterial classification system and was easy to follow. A new classification system was proposed in 1971 by Suzuki T and coworkers. They defined three groups based on number of hepatic arteries at hilar region. Our case series of three cases highlights the complimentary role of three hepatic arterial classification systems given by Michel NA, Hiatt JR and coworkers and Suzuki T and coworkers. We conclude that introduction of Suzuki classification is useful for describing rare variants of hepatic arterial pattern not covered in already known hepatic arterial classification systems. It is our firm believe that Suzuki classification would act as an adjunct to already known classification systems by Michel and Hiatt and should not replace already known classification systems.
