Robot-assisted laparoscopic reconstructed management of multiple aneurysms in renal artery primary bifurcations: a case report and literature review

摘要

BACKGROUND: Renal artery aneurysm (RAA) is rare and its incidence in the general population remains elusive. There have been few reports on the repair of multiple aneurysms conducted with the Da Vinci robot-assisted surgical platform (Intuitive Surgical Inc., Sunnyvale, CA, USA), especially for those located in renal artery primary bifurcations. CASE PRESENTATION: We report our experience in the surgical management of two expanding right-sided RAAs in a 64-year-old man using a robot-assisted laparoscopic approach. Two aneurysms were located in renal artery primary bifurcations, whose diameter was 1.8 and 1.2 cm. The aneurysms were resected and the renal artery branch reconstructed by in situ arteriorrhaphy. The operation lasted for 2 h and 35 min with a warm ischemia time of 26 min and estimated blood loss of 150 ml. The hospital stay was 6 days. The computed tomography (CT) scan performed 2 months after the surgery showed resolution of the aneurysms. Additionally, split renal function indicated the preservation of right renal function in the follow-up period. CONCLUSIONS: The robot-assisted laparoscopic procedure is a safe and effective surgical technique, which may be considered as an alternative to open surgery for complex multiple RAAs in the future.
