CELIAC TRUNK – HEPATIC ARTERIAL SYSTEM AND RENAL ARTERIES, ANATOMICAL VARIATIONS IDENTIFICATION, PREVALENCE AND ASSOCIATION : ANALYSIS USING MDCT

Dr. P. Sneha Madhavi, Dr. R. Ramesh Kumar

Abstract :

AIMS AND OBJECTIVES:

� Aim of this study is to determine the anatomical variants of celiac trunk, hepatic arterial system and renal arteries , their pervasiveness with the use of contrast enhanced Multi detector computed tomography (MDCT) and post processing techniques like Multiplanar reconstruction(MPR), Maximum intensity projection(MIP) and Volume rendering technique (VRT).

� The variations are individually described and the association between occurance of renal artery and celiac–hepatic artery variations is statistically evaluated.

METHODS AND MATERIALS:

We conducted a retrospective analysis in 521 patients referred to the Department of Radio diagnosis from December 2016 to December 2017 for various abdominal pathologies.

The imaging (CE MDCT) was performed using GE Bright Speed Elite 16 Slice CT Scanner.

All the patients have undergone plain CT followed by triphasic CECT abdomen with multiplanar reconstruction, maximum intensity projection and volume rendering post processing.

RESULTS :

In our retrospective study in 521 patients, comprising 276 (53%) men and 245 (47%) women between the age of 9 to 72 years (Mean age of 31.5 years) celiac trunk variations were present in 44 patients (8.4%), Hepatic artery variations were present in 128 patients (24.6%) and renal artery variations were seen in 232 patients (44.5%).

Celiac trunk and/or hepatic artery variation was present in 63 (21.8%) of 289 patients without renal artery variation and in 95 (40.9%) of 232 patients with renal artery variations.

There is an increased prevalence of celiac–hepatic artery variations in individuals with accessory renal arteries.

CONCLUSION :

Prior evaluation of arterial variations is of paramount importance before abdominal interventional and surgical procedures.

Contrast enhanced MDCT with Multiplanar reformation (MPR), Maximum intensity projection (MIP) and Volume rendering technique (VRT) post processing is a noninvasive diagnostic technique of high preference holding prime importance in accurate detection and characterization of anatomical vascular variants of celiac trunk, hepatic artery and renal arteries.
