Management of huge splenic artery aneurysm with new hybrid procedure including endovascular and open surgical approach: Case series

INTRODUCTION: Splenic artery aneurysms (SAAs) account for more than half of all visceral artery aneurysms. Small SAAs are usually asymptomatic, but giant aneurysms are more likely to cause symptoms and result in life-threatening complications; these aneurysms treatment can be challenging. Splenic artery aneurysms treatment includes laparotomy, laparoscopy, or endovascular techniques. CASE PRESENTATION: This case series reports the details of successful management of three patients with huge splenic artery aneurysms who underwent hybrid surgery, endovascular inflow control with a balloon, and open aneurysm resection. DISCUSSION: Although endovascular treatment options are increasingly favored, only selected aneurysms are suitable for these procedures, as marked tortuosity of the artery or SAA in the proximal splenic artery may not be suitable for endovascular management. CONCLUSION: Open surgery escorted by endovascular techniques can be considered an ideal treatment of SAA in the proximal region of the splenic artery.
