Anatomical Variations of the Celiac Artery Detected by Multidecteor Computated Tomography

Abstract

Background: Multi detector computed tomography (MDCT) is form of computed tomography technology for diagnostic imaging for diagnosis of celiac trunk variations. Purpose: This study aims to describe the main anatomical variations of the celiac artery and its branches using Multi detector computed tomography. Patients and Methods: This study included 30 patients with signs and symptoms of various liver and other abdominal pathologies in which biphasic or triphasic contrastenhanced CT was indicated (to study early arterial phase). Results: The commonest variant in our study was Uflacker type II (hepato-splenic trunk) in which CHA and SA have common trunk and LGA arises separately from aorta representing 40% while Uflacker type V (gastro-splenic trunk) in which the origin of the CHA from either the SMA or the aorta was the second common variants representing 20%. Conclusion:Knowledge of the celiac trunk anatomical variants is very important presurgical, pre-laparoscopic or even pre-interventional and this can be achieved using MDCT to minimize and avoid the major vascular complications and decrease the morbidity of patients , late arterial phase of computed tomography is sufficient for assessing celiac trunk variants.

Prevalence of hepatic vascular anomalies in consecutive contrast-enhanced computed tomography images — a retrospective observational study

“…It has various threedimensional imaging techniques, such as multiplanar reconstruction (MPR), volume rendering, and maximum intensity projection (MIP), which have enhanced the imaging of venous structures. Faster imaging with high resolution and less need for contrast media has made MDCTs inevitable to interventional radiologists and surgeons for detailed evaluation of various anatomical structures before HPB surgeries and interventional procedures [2]. MDCTs precisely delineate the hepatic vascular anomalies preoperatively, which would assist the surgeon to avoid inadvertent vascular injury during surgery by anticipating the course of hepatic vascular variants and aids in preserving anomalous vessels unless their division or resection is required to get the oncological clearance.…”
