PROSPECTIVE PRE-OPERATIVE EVALUATION OF HEPATIC VASCULAR ANATOMY IN LIVER TRANSPLANT DONORS, RECIPIENTS AND HEPATIC RESECTION CANDIDATES BY SIXTEEN-ROW MULTIDETECTOR COMPUTED TOMOGRAPHY ANGIOGRAPHYMishra A, El Usta A, Shwayesh T, Ehtuish EF
To assess the accuracy of sixteen-row multidetector computed tomography angiography (MDCTA) in preoperative evaluation of hepatic vascular anatomy, 52 liver donors, 12 liver recipients and 11 patients for hepatic resection underwent MDCTA with sixteen-row CT scanner during 11-month period. 0.625 mm. axial images were acquired in arterial, portal and hepatic venous phases with 50% overlap. Post-processing included multiplanar reconstructions, maximum-intensity projection and volume-rendering techniques. Findings were analyzed by two radiologists and compared with surgical findings in 23 patients. MDCTA examinations were technically satisfactory in all patients for arterial scan but for venous phases in only 47 (90.4%) donors, 5 (41.7%) recipients and 10 (90.9%) patients for hepatic resection. Arteries up to tertiary branches were identified in 73 (97.3%) patients. Segment IV artery was seen originating from right hepatic artery in 26 (34.7%) patients. 21 (28%) patients showed right hepatic artery arising from superior mesenteric artery while 13 (17.3%) had an accessory artery from superior mesenteric artery to segment IV.
