AIM: To evaluate the spectrum of hepatic arterial variants in unselected patients undergoing computed tomography (CT) of the abdomen at the main regional referral centre in the northern Anglophone Caribbean. MATERIALS AND METHODS: Two radiologists independently reviewed 309 CT angiographic studies performed over 2 years between 1 July 2010 and 30 June 2012 at a regional hepatobiliary referral centre for the Northern Caribbean. The anatomical variations were described according to a conventional classification proposed by Michels et al. RESULTS: In this Caribbean population, the majority of patients had conventional Michels' type 1 vascular anatomy (63.4%). However, a statistically significantly greater incidence of Michels' type 2 variations (20.4%) were found than that reported in the international literature and a lower incidence of type 3 (5.2%), type 6 (0.6%), and type 9 (0) patterns than previously reported. One case with variations not previously described in this classification was also encountered. CONCLUSION: Although 63.4% of persons in a Caribbean population have conventional vascular anatomy, the distribution of anatomical variants is quite different to that seen in North American and European centres. Interventional radiologists and hepatobiliary surgeons practicing in the Caribbean must be cognizant of these differences in order to minimize morbidity and mortality during invasive procedures.
