OBJECTIVE: To evaluate technical aspects and clinical results of transcatheter arterial embolization (TAE) for delayed postoperative arterial bleeding after pancreatic surgery. MATERIAL AND METHODS: There were 821 pancreatectomies between 2012 and 2020. Delayed bleeding occurred in 106 (12.9%) patients; 74 patients were included in the study. Previous pancreatic head resection was carried out in 75.7% of cases, pancreatic body resection - in 17.6% of cases, pancreatic tail resection - in 6.8% of patients. Primary endpoint was technical success of TAE, secondary endpoints - complications after TAE, as well as recurrent bleeding after embolization. RESULTS: Angiography of celiac-mesenteric arterial system was performed in 74 patients (91 procedures). The most common sources of bleeding were gastroduodenal and superior mesenteric arteries (35.7%), jejunal arteries (13.1%), common hepatic artery (11.9%). Combination of embolization agents was applied for TAE (metal coils and non-calibrated PVA particles, 48.6%). In 11 (14.9%) patients, we applied stent-grafts. Technical success rate was 100%. Recurrent bleeding occurred in 13 (17.6%) patients. In-hospital mortality was 12.2% (n=9). CONCLUSION: TAE is an effective treatment procedure in patients with arrosive bleeding. This method is characterized by high technical efficiency and low in-hospital mortality, but it does not affect recurrence of bleeding.

Pancreatic surgery is complex and associated with a risk of complications including bleeding. Bleeding after pancreatic surgery is rare, but characterized by high mortality. This review is devoted to classification, diagnosis and treatment strategies for bleeding after pancreatic surgery. Methods and results of endovascular surgery are of special attention.
