Study of Anatomic Variation of Coronary Arteries for Sudanese Using Cardiac CT Scan Angiography CCA

Abstract

This descriptive analytic study aimed to study anatomic variation of coronary arteries among the Sudanese using cardiac CT angiography. The study done for 87 patients of cardiac CTA examination, data were collect from 3D reconstruction at optimal phase, the number diagonals, obtuse marginal were account. The presence of ramus intermediate and origin of the RCA coronary artery were reported. The study found the following results: 3 patients (3.4%) hadn’t diagonal, 29 patients (33.3%) had one D, 41 patients (47.1%) had two D, 11 patients (12.6%) had three D, 3 patients (3.4) had more. 7 patients (8%) hadn’t OM, 21 patients (24.1%) had one OM, 36 patients (41.4%) had two OMs, 22 patients (25.3%) had three OMs, one patient (1.1%) had more. 70 patients (80.5%) hadn’t ramus and 17 patients (19.5%) had ramus intermediate. 82 patients ( 94.3%) had RCA originate from RCS and 5 patients (5.7%) had ectopic originate from LCA. Also the study found positive significant correlation between pathological findings and presence of ramus intermediate. The study concluded that's wide variations on numbers of diagonals which arise from left anterior descending and obtuse marginal which arise from LCX of Sudanese. Ectopic originate of RCA was very rare. And the Sudanese con not different from other people. The study recommended more studies about numbers coronary artery branches and it's relation to the heart size with large sample of Sudanese population
