Abstract
BACKGROUND: Hybrid and endovascular procedures maybe effective and less invasive alternatives to open surgery for treatment of extracranial carotid artery aneurysm (ECAA), but the optimal management of juxta-skullbase ECAA is controversial. OBJECTIVE: This study evaluated the long-term effects of hybrid and endovascular procedures in treating juxta-skullbase ECAA. METHODS: The records of 9 consecutive patients who underwent hybrid or endovascular interventions for juxta-skullbase ECAA in a single center from April 2014 to May 2020 were retrospectively reviewed. RESULTS: Four patients presented with a pulsating mass, 1 with dysphagia, 1 with pain in the left temporal region, 1 with dizziness and headache, 1 with cerebral infarction, and 1 with dizziness and cerebral infarction. Seven true aneurysms, 1 false aneurysm, and 1 dissecting aneurysm were diagnosed with CTA in the 9 patients (mean age, 50.8±20.3 years; 1 male). The aneurysms were divided into two subgroups: 4 type I, and 5 type IIb according to a recent classification. Per schedule, 7 patients (4 type I and 3 type IIb) were treated with endovascular intervention, and 2 (type IIb) were treated with hybrid procedures. The technique success rate was 88.9%. One patient (type IIb) who was scheduled to be treated with an endovascular procedure was transferred to a hybrid procedure because of failure of the endovascular procedure. Eleven covered stents were implanted to exclude the aneurysms. During follow-up (mean duration 31.2±23.2 months), all aneurysms were proven excluded, no significant complication occurred, and preoperative symptoms resolved. One patient (type I) in the endovascular group had occlusion of the internal carotid artery but no symptoms; the internal carotid artery was patent in the other 8 patients. CONCLUSIONS: Hybrid and endovascular procedures were found effective and durable alternatives to open operation for treatment of extracranial juxta-skullbase carotid aneurysm.
