Summary
Overlapping stent-assisted coil embolization (OSCE) is a safe and effective treatment for vertebrobasilar dissecting aneurysms (VBDAs). This technique demonstrates favorable clinical and imaging outcomes in both ruptured and unruptured VBDA cases.
Area of Science:
- Neurology
- Interventional Neuroradiology
- Vascular Surgery
Background:
- Vertebrobasilar dissecting aneurysms (VBDAs) present significant treatment challenges due to high morbidity and mortality.
- Current treatment strategies for VBDAs lack definitive consensus.
Purpose of the Study:
- To evaluate the safety and efficacy of overlapping stent-assisted coil embolization (OSCE) for treating VBDAs.
- To assess clinical and radiological outcomes of OSCE in VBDA patients.
Main Methods:
- Retrospective analysis of 42 VBDA patients treated with OSCE between May 2015 and August 2019.
- Assessment of clinical and radiological parameters at discharge and follow-up.
- Evaluation of safety, technical feasibility, and long-term imaging results.
Main Results:
- Successful overlapping stent implantation in all patients.
- All patients achieved effective clinical outcomes (modified Rankin Scale 0-2).
- Favorable outcomes observed in 41 of 42 patients during a median 28-month follow-up; one perioperative death.
- Complete aneurysm occlusion achieved in all cases, with one instance of parent artery closure.
Conclusions:
- Overlapping stent-assisted coil embolization (OSCE) is a safe and effective treatment modality for vertebrobasilar dissecting aneurysms.
- The technique yields favorable clinical and imaging results for both ruptured and non-ruptured VBDAs.
- OSCE offers a promising therapeutic option for complex VBDA cases.
