What does this research mean for the field?

Preoperative segment-specific endoluminal internal carotid artery (ICA) stent reinforcement is a feasible adjunct for carotid preservation during repeat resection of irradiated skull-base tumors with circumferential ICA encasement and balloon test occlusion failure. Novelty: ClaimNovelty.METHODOLOGICAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To assess the feasibility of staged, segment-specific endoluminal internal carotid artery (ICA) stent reinforcement to allow carotid-preserving re-resection in recurrent irradiated skull-base malignancies.

Overview

Prospective series demonstrates feasible carotid-preserving resection using endoluminal stents in recurrent skull-base tumors, suggesting an alternative to high-flow bypass.

Key Points

To assess the feasibility of staged, segment-specific endoluminal internal carotid artery (ICA) stent reinforcement to allow carotid-preserving re-resection in recurrent irradiated skull-base malignancies.
Prospective single-center study evaluating patients with recurrent skull-base tumors previously treated with surgery and radiotherapy who exhibited 360° ICA encasement and failed balloon test occlusion.
High-resolution MRI fused with 3D-rotational angiography guided segment-specific deployment of balloon-expandable covered stents (petrous, lacerum, and cavernous ICA) or open-cell/flow-diverting stents (clinoidal ICA).
Patients received dual antiplatelet therapy for 3 months prior to tumor re-resection under aspirin monotherapy.
Resection outcomes included gross-total resection in two patients, near-total in one, and subtotal in one (with complete clearance of ICA-adjacent disease).
One patient (25%) developed delayed postoperative carotid occlusion from in-stent stenosis following required antiplatelet interruption, complicated by iatrogenic injury during thrombectomy, both resolved endovascularly.
Zero cases of intraoperative carotid rupture or permanent stent-related neurological deficits occurred.
