Accessory Inferior Sulci of the Liver in an Afro-Caribbean Population
[摘要] Introduction: Therehave been no previous reports on the anatomic variations that exist on inferiorsurface of the liver in Caribbean populations. This information is important tooptimize radiology and hepatobiliary surgical services in the region. Methods:Two investigators independently observed 69 cadaveric dissections over fiveyears and described the variations in surface anatomy. Results: Inthis population 88% of cadaveric livers had conventional hepatic surfaceanatomy. However, 12% had accessory sulci present on the visceral surface ofthe liver, with a 7:1 male preponderance. When present, there was 100%correlation between the presence of Rouvière’s sulcus and the right branch ofportal pedicle. Conclusion: Abnormalsurface anatomy is present in 12% of unselected specimens in this Caribbeanpopulation. Interventional radiologists and hepatobiliary surgeons practicingin the Caribbean must be cognizant of these differences in order to minimizemorbidity during invasive procedures.
