The absence of the common hepatic artery and its implications for surgical practice. Results of a systematic review and meta-analysis
Introduction: The common hepatic artery (CHA)is the main arterial supply to the liver. Common classifications of the anatomical variations of the celiac trunk have only marginally described the CHA. Currently, the only classification addressing anatomical variants in cases of CHA absence from the celiac trunk is that reported by Huang et al. In this systematic review, the prevalence of these variations, according to Huang's classification, have been analyzed. Methods: The review was registered in PROSPERO (CRD 42018096679). The risk of bias was assessed using the AQUA tool.
