OBJECTIVES: The aim of the present study was to evaluate variations in celiac trunk and hepatic artery with multi-detector computed tomography (MDCT).

PATIENTS AND METHODS: Totally 820 patients who underwent angiography of the abdominal aorta were evaluated. Anatomical findings were grouped according to the Michels classification.

RESULTS: Several variations and/or anomalies were noted in 33.2% of the patients (n=272). The most common abnormality was Michels type III (10.1%), followed by type V (7.3%), type II (4.7%) and others. Type X was not observed in our series. We have noted additional, previously unclassified variations in 12 cases (1.5%).

CONCLUSIONS: Preoperative knowledge of variant anatomy may assist in the selection of treatment options and surgical planning, which in turn facilitates surgical dissection and helps avoiding iatrogenic injury. MDCT angiography allows detailed visualization of the vascular anatomy.
