Abstract

Background: Superficial temporal artery (STA) aneurysms are relatively rare diseases, and the treatment approach is based on factors such as the location of the aneurysm, curability, complications, and patient request. However, the detailed outcome of STA aneurysms treated with endovascular surgery remains unknown.

Case description: A 75-year-old woman found a pulsatile mass lesion at a preauricular region with gradual enlargement. Angiography showed a thrombosed aneurysm originating from STA. Endovascular trapping was selected because she rejected open surgery for cosmetic reasons. Intra-aneurysmal blood flow disappeared on postoperative angiography. However, the aneurysm had enlarged for 8 months after the initial embolization. A recurrent aneurysm was resected, and pathological examination revealed neovascularization within the thrombotic lesion, suggesting neovascularization and re-canalization.

Conclusion: Endovascular trapping for thrombosed STA aneurysm might include recurrent risk, and direct resection should be considered as the first-line treatment.

部分血栓形成的颞浅动脉瘤在血管内夹闭后复发：1例报告及文献复习。

背景：颞浅动脉（STA）动脉瘤是一种相对罕见的疾病，其治疗方法取决于动脉瘤的位置、可治愈性、并发症和患者要求等因素。然而，血管内手术治疗STA动脉瘤的详细结果尚不清楚。病例描述：一名75岁女性在耳前区发现搏动性肿块，逐渐增大。血管造影显示起源于STA的血栓性动脉瘤。选择血管内诱捕术是因为她因美观原因拒绝开放手术。术后血管造影显示动脉瘤内血流消失。然而，动脉瘤在最初栓塞后8个月扩大。一个复发的动脉瘤被切除，病理检查显示血栓病变内新生血管，提示新生血管和再通。结论：血管内夹闭治疗血栓性STA动脉瘤可能有复发风险，应考虑直接切除作为一线治疗。
