Treatment of aneurysms in the splenic and renal arteries in a single operation: case report and review

Abstract Visceral and renal artery aneurysms are rare (0.01 to 2%) and their risk of rupture varies between different types and depending on their anatomy and patient context (comorbidities, pregnancy, and liver transplant history). Mortality due to rupture of these aneurysms is around 25%. New techniques and materials derived from neurointervention seem to be promising options for treatment of these aneurysms. In this context, we report the case of a patient undergoing endovascular treatment of both splenic artery and renal artery aneurysms during the same procedure, using Solitaire stents and controlled release coils in both repairs. The patient recovered well with both aneurysms adequately treated. In conclusion, endovascular treatment of splenic and renal artery aneurysms during the same operation is feasible and has proved safe and effective in the case reported.

摘要：内脏动脉与肾动脉动脉瘤（Visceral and renal artery aneurysms）属于罕见病变，发病率为0.01%至2%，其破裂风险因病变类型、解剖特征及患者个体情况（合并症、妊娠、肝移植病史）而异。此类动脉瘤破裂引发的死亡率约为25%。源自神经介入领域的新技术与新材料，为这类动脉瘤的治疗提供了颇具前景的方案。在此背景下，本文报告1例患者在同一手术中同期接受脾动脉与肾动脉动脉瘤血管内治疗，术中双侧修复均使用了Solitaire支架（Solitaire stents）与可控释放弹簧圈（controlled release coils）。该患者术后恢复良好，两处动脉瘤均得到妥善处理。综上，同期开展脾动脉与肾动脉动脉瘤血管内治疗具备可行性，且在本次报告病例中被证实安全有效。
