Background:
Hepatic arterial variations were fully elaborated in anatomical monographs. Here, we aimed to present a rare case with multiple arterial variations of the liver complicated laparoscopic pancreaticoduodenectomy.
Case Presentation:
We report a 67-year-old woman with a periampullary tumor underwent laparoscopic pancreaticoduodenectomy. Intraoperatively, the aberrant right hepatic artery derived from the gastroduodenal artery (GDA) was observed and had accidentally sacrificed due to untimely ligature of GDA. Three-dimensional reconstruction based on preoperative contrast-enhanced CT performed to better study the anatomy. It demonstrated a replaced right hepatic artery branched from the GDA and supplied right liver lobe. Meanwhile, the middle hepatic artery derived from the common hepatic artery and supplied hepatic segment IV. Additionally, the replaced left hepatic artery emerged from the left gastric artery and fed into left liver lobe.
Conclusions:
The origination and course of hepatic arterial anatomy should be thoroughly assessed in planning and performing hepatopancreatobiliary surgeries. Reconstruction images of contrast-enhanced CT are helpful to visualize the vascular variations and its spatial relation with adjacent structures.
