Objectives: To evaluate the effectiveness of surgical treatment in patients with visceral artery aneurysms using the da Vinci Xi robotic surgical system

Methods: The study included 42 patients who underwent robot-assisted treatment between 2022 and 2025: 38 (90%) subjects had true splenic artery aneurysms, 2 (5%) - had renal artery aneurysms, and 2 (5%) - had hepatic artery aneurysms. Among 38 patients with splenic artery aneurysms there were 26 (68%) females and 12 (32%) males. Preoperative assessment included contrast-enhanced computed tomography with 3D modeling.

Results: The surgical treatment strategy depended on the localization of the aneurysm, the tortuosity of the artery, the presence of calcification in the aneurysm wall, and the severity of adhesions to surrounding organs and tissues. Clipping of the splenic artery was performed in patients with multiple visceral aneurysms (n=5, 13%), aneurysms in the splenic hilum (n=9, 24%), as well as in cases with a calcified splenic artery and aneurysm wall (n=8, 21%), i.e. when vascular reconstructions were technically impossible. In cases of saccular aneurysms at the orifice or in the bifurcation area of the splenic artery, we performed aneurysm wall resection followed by edge-to-edge vascular suturing (n=7, 18%).
An end-to-end anastomosis after aneurysm resection was performed in 9 (24%) patients. The average diameter of the aneurysms was 35.2±1.8mm ranging from 18 to 71 mm. The average duration of the procedure was 73.8±12.5 minutes, the time required for forming the anastomosis was 18.5±1.5 minutes, and the occlusion of the splenic artery lasted 19.5±2.6 minutes. The average postoperative hospital stay was 4.5±1.5 days. In one case (2.6%) a conversion was required due to bleeding at the anastomotic site after aneurysm resection with and end-to-end anastomosis.
Two patients with renal artery aneurysm underwent aneurysm resection with an edge-to-edge vascular suturing. In one case, the patient developed intraoperative thrombosis, which required grafting using an autologous vein. Two patients with hepatic artery aneurysm underwent aneurysm ligation and grafting using a reversed great saphenous vein.

Conclusions: Robot-assisted surgery is an effective alternative to open procedures when endovascular treatment is not an option. The use of robotic techniques helps reduce the complication rates, decrease intraoperative blood loss, shorten hospital stays, and accelerate patient recovery.
