Abstract
Celiac artery (CA) occlusion, or stenosis, is not uncommon, and most cases are asymptomatic. If the CA is occluded, collateral circulation from the superior mesenteric artery (SMA) is maintained through the pancreaticoduodenal arcade. However, the pancreaticoduodenal arcade is removed if pancreaticoduodenectomy (PD) is performed, which results in ischemia of the liver, stomach, and residual pancreas. Thus, these patients require CA revascularization, which can include antegrade endovascular reconstruction and retrograde reconstruction using vascular anastomosis from the SMA system to the CA system. Both methods carry risks of restenosis or anastomotic thrombosis. We report a technique that involves a combination of both revascularization methods in an 89-year-old man who underwent PD for lower bile duct cancer. Preoperative endovascular stent placement in the CA preserved antegrade blood flow to the liver, and intraoperative vascular anastomosis of the jejunal artery and right gastroepiploic artery achieved retrograde blood flow. Although we confirmed both stent and anastomosis patency and blood circulation in our case, obstruction of 1 of these revascularization pathways would not likely lead to ischemia of the liver. Thus, our 2-way revascularization technique for managing celiac artery stenosis during PD may reduce the risk of organ ischemia.
