Dynamic Intraductal Endoscopic Visualization of Right Hepatic Artery Pulsation Underlying Minor Vascular Impression of the Proximal Bile Duct

Right hepatic artery (RHA) syndrome is a well-recognized, though an uncommon cause of benign bile duct stricture, potentially simulating malignancy. Albeit the latter was not the case in this unique clinical report after cholangitis resolution and clearance of biliary sludge and debris, high-quality direct cholangioscopy (DC) illustration of the RHA overriding the proximal common bile duct with well visible arterial pulsation has not yet been reported before. Beyond its potential visual informativeness, this uncommon cholangioscopic documentation may provide key didactic advances in terms of intraductal visualization of the anatomy of the biliary tree.
