Abstract

INTRODUCTION:

There have been no previous reports on the anatomic variations that exist on inferior surface of the liver in Caribbean populations. This information is important to optimize radiology and hepatobiliary surgical services in the region.

METHODS:

Two investigators independently observed 69 cadaveric dissections over five years and described the variations in surface anatomy.

RESULTS:

In this population 88% of cadaveric livers had conventional hepatic surface anatomy. However, 12% had accessory sulci present on the visceral surface of the liver, with a 7:1 male preponderance. When present, there was 100% correlation between the presence of Rouvière's sulcus and the right branch of portal pedicle.

CONCLUSION:

Abnormal surface anatomy is present in 12% of unselected specimens in this Caribbean population. Interventional radiologists and hepatobiliary surgeons practicing in the Caribbean must be cognizant of these differences in order to minimize morbidity during invasive procedures.
