Variations of the celiac trunk investigated by multi-detector computed tomography: systematic review and meta-analysis with clinical correlations
Abstrakt
INTRODUCTION: In recent years multi-detector computed tomography (MDCT) has been used to investigate vascular anatomy for scientific and diagnostic purposes. These studies allow for much larger sample sizes than traditional cadaveric studies.
The aim of this research was to perform a systematic review and meta-analysis on studies investigating the variations of the celiac trunk using MDCT. METHODS: Major medical databases were used to find studies investigating celiac trunk anatomy using MDCT.
Extracted information included demographic details, number of normal celiac trunks and number of each variant celiac trunk. Using a random effects meta-analysis the pooled prevalence of each variation was calculated.
RESULTS: A total of 36 studies from fourteen countries and four continents were included in the meta-analysis. The total number of subjects included was 17,391.
The total prevalence of variant celiac trunks was 10.85%. The different types of celiac trunk variations with their prevalences were: gastrosplenic trunk (3.46%), hepatosplenic trunk (3.88%), hepatogastric trunk (0.24%), absent celiac trunk (0.28%), celiacomesenteric trunk (0.46%), hepatosplenomesenteric trunk (0.26%), gastrosplenomesenteric trunk (0.07%), and celiacomesenteric anastomosis (0.09%).
A total of 61 cases (0.19%) were either not described or not described adequately to be included in our classification. CONCLUSION: Major variations of the celiac trunk are not uncommon and should be anticipated before radiological and surgical interventions.
Knowledge of celiac trunk anatomy is important in hepatopancreatobiliary surgery, transplantology and interventional radiology.
