Summary

Extracranial internal carotid artery aneurysms (EICAAs) are rare. Both endovascular treatment and hybrid surgery offer feasible and satisfactory short-term outcomes for EICAAs.

Area Of Science

Vascular Surgery
Interventional Neuroradiology
Cerebrovascular Diseases

Background

Extracranial internal carotid artery aneurysms (EICAAs) are uncommon vascular lesions.
Treatment options for EICAAs include endovascular techniques and hybrid surgical approaches.

Purpose Of The Study

To evaluate the clinical outcomes of endovascular treatment versus hybrid surgery for EICAAs.
To assess the feasibility and efficacy of these interventions at a single institution.

Main Methods

Retrospective review of 28 patients with 30 EICAAs treated between January 2013 and June 2023.
Analysis of clinical characteristics, aneurysm features, perioperative outcomes, and follow-up data.

Main Results

Overall technical success rate was 90.0% (27/30).
One perioperative minor stroke occurred in the endovascular group (6.7%).
The overall patency rate was 93.1% (27/29) at a median follow-up of 17.5 months.

Conclusions

Endovascular treatment and hybrid surgery are viable treatment options for EICAAs.
Both approaches demonstrate satisfactory short-term clinical results.
