Background: Splenic artery aneurysms are rare, but their occurrence is burdened by considerable mortality and morbidity rates. Although the indications to treatment are quite clear-cut, there is still debate on the first-choice technique of treatment (endovascular, open, or laparoscopic surgery). Recently, robotic surgery has been proposed as an alternative option in patients at high surgical risk. The present case series aims to assess the value of robotic treatment of splenic artery aneurysms in patients unfit for surgery. Methods: All cases of splenic artery aneurysms treated by robotic surgery at our center between 2014 and 2018 were retrospectively reviewed. Primary endpoints were clinical and technical success and disease-free survival. Results: Robotic surgery was used to treat four patients affected by splenic artery aneurysms, with the guidance of 3D printed patient-specific models. All patients, after aneurysm excision, received reconstruction of the splenic artery by direct anastomosis. All cases were treated successfully without mortality. Reintervention-free survival at 24-month mean follow-up is 100%, and no systemic complication of clinical relevance was reported. The mean time of organ ischemia was 45 min. Conclusions: Robotic surgery is a safe and effective option in treating visceral aneurysms, providing the possibility to reconstruct the splenic artery after aneurysm excision.
