Analysis of anatomical variations of the main arteries branching from the abdominal aorta, with 64-detector computed tomography
BACKGROUND: Great variability in the vasculature of the abdominal organs makes the pre-operative evaluation of arterial anatomical conditions extremely important and helpful. The aim of our study was to establish the prevalence of anatomical variations of the arteries branching from the abdominal ao...

description | BACKGROUND: Great variability in the vasculature of the abdominal organs makes the pre-operative evaluation of arterial anatomical conditions extremely important and helpful. The aim of our study was to establish the prevalence of anatomical variations of the arteries branching from the abdominal aorta and to compare the results with the ones presented in the literature. MATERIAL/METHODS: The material included computed tomography angiographies (CTA) of 201 patients (91 women and 110 men) performed between September 2007 and December 2008. The CTA examinations were conducted with a 64-detector CT scanner at the Department of Radiology of University Hospital in Wrocław. Images were obtained during the arterial phase and were analyzed for the presence of potential anomalies of the branches of the abdominal aorta. RESULTS: In 88 patients (43.8%), there were anatomical variations of the arteries branching from the abdominal aorta. Variations of the renal arteries were observed in 83 (41.3%) patients, anomalies of the celiac trunk in 9 patients (4.5%), including variations of the superior mesenteric artery in 4 (2%) patients. No anatomical anomalies of the inferior mesenteric artery were shown in this study. The most frequent anomaly of the renal vasculature was the presence of at least one additional renal artery, observed in 65 (32.3%) patients. This concerned the inferior renal polar artery mainly – in 30 (14.9%) patients. Presence of bilateral additional renal arteries was visualized in 10% (20/201) of the cases. The most frequent anomalies of the celiac trunk were the celiacmesenteric trunk (in 3 patients – 1.5%) and the hepatosplenic trunk (in 3 patients – 1.5%). The celiac-mesenteric trunk was also the most frequent variation of the superior mesenteric artery in our material. CONCLUSIONS: A large part of population – 43.8% of our patients – demonstrated variations of arteries branching from the abdominal aorta. The anomalies were significantly more often found within the renal arteries than within the celiac trunk or the superior mesenteric artery. Sixty-four detector CTA reveals a high sensitivity in the detection of anomalies of the arteries branching from the abdominal aorta. |
