title: Proximal duodenal obstruction associated with compression from a replaced right hepatic artery.
abstract: Replaced right hepatic artery is a well-described normal anatomical variant, not previously associated with acute or chronic abdominal symptoms or long-term sequelae. We report a 15-year-old girl presenting with nearly a decade of symptoms secondary to external compression of the proximal duodenum by the ventral passage of a replaced right hepatic artery. Surgical bypass of the duodenal obstruction significantly improved her symptoms. Replaced right hepatic artery related duodenal compression should be considered in the differential diagnosis of proximal duodenal obstruction. The presence of the replaced right hepatic artery should be clearly communicated to allow optimal presurgical planning.
