Post-pancreaticoduodenectomy hemorrhage is a life threatening complication reported to occur in 2-7% of patients. Historically, treatment required an exploratory laparotomy. Introduction of endovascular embolization has broadened the available treatment options. The most common location for a post-pancreaticoduodenectomy hemorrhage is the gastroduodenal artery stump. Nonetheless, unusual sources of hemorrhage exist and are hard to localize, thus they are often treated with open surgery. Here we report two cases of CTA proven hemorrhage from the dorsal pancreatic arcade and transverse pancreatic artery, which were successfully located with conventional angiography and treated with endovascular arterial coil embolization. Both patients were status post-pancreaticoduodenectomy (Whipple procedure) and presented with a sentinel bleed and a drop in hematocrit levels.
