JOURNAL OF VASCULAR SURGERY. Endovascular treatment of hepatic artery stenosis after liver transplantation

Blake A. Hamby, MD , Daniel E. Ramirez, MD , George E. Loss, MD, PhD , Hernan A. Bazan, MD , Taylor A. Smith, MD , Edward Bluth, MD , W. Charles Sternbergh III, MD

Background: Hepatic artery stenosis (HAS) after orthotopic liver transplantation is a significant risk factor for subsequent hepatic artery thrombosis (HAT). HAT is associated with a 30%-50% risk of liver failure culminating in retransplantation or death. Traditional treatment of hepatic artery complications has been surgical, with hepatic artery revision or retransplantation. Endovascular therapy of HAS, described primarily in the interventional radiology literature, may provide a less-invasive treatment option.

JOURNAL OF VASCULAR SURGERY. Comparative analysis of celiac versus mesenteric artery outcomes after angioplasty and stenting

Sadaf S. Ahanchi, MD , Christopher L. Stout, MD , Tyler J. Dahl, BBmE , Rebecca L. Carty, MD , Cory A. Messerschmidt, BS , Jean M. Panneton, MD

Background: Open bypass is the gold standard for treatment of mesenteric ischemia. With the refinement of endovascular therapy, visceral stenting is an attractive minimally invasive alternative, but the data are limited and which vessel responds best to stenting has not been addressed. This study compares the outcomes of superior mesenteric artery (SMA) and celiac artery (CA) stenting.
