{Abstract}: OBJECTIVE: This study aimed to assess the safety and efficacy of endovascular treatment of unruptured pancreatic arcade aneurysms in a single-center series.
METHODS: The electronic medical records of patients who underwent endovascular treatment for unruptured pancreatic arcade aneurysms between 2011 and 2022 at our tertiary center were retrospectively reviewed. The presence of celiac artery stenosis/occlusion; aneurysm number, location, and size; endovascular technique; procedure-related complication incidence; and clinical outcomes were assessed.
RESULTS: Twenty-three patients (12 men and 11 women; mean [range] age, 63.8 [45-84] years) with 33 unruptured pancreatic arcade aneurysms were identified. Celiac artery stenosis/occlusion coexisted in 17 (74%) patients. Five (21%) patients had multiple aneurysms. The median aneurysm size was 9.3 mm (range, 4-18 mm). Seven, 6, 6, 5, 4, 3, and 2 aneurysms were located in the gastroduodenal, dorsal pancreatic, anterior superior pancreaticoduodenal, inferior pancreaticoduodenal, posterior inferior pancreaticoduodenal, posterior superior pancreaticoduodenal, and anterior inferior pancreaticoduodenal arteries, respectively. Four (15%) and 22 (85%) aneurysms were treated with endosaccular packing alone and coil embolization with endosaccular packing and parent artery occlusion, respectively, with resulting exclusion from arterial circulation. The remaining 7 aneurysms coexisting with larger aneurysms in other peripancreatic arteries were observed without embolization because they were small and for preserving collateral blood flow to the celiac artery. The treated aneurysms did not rupture or recur during the follow-up period (median, 40 months).
CONCLUSIONS: Endovascular treatment is a safe and effective treatment for unruptured pancreatic arcade aneurysms.
METHODS: 3, non-controlled retrospective cohort study.
