Summary
Selecting the anterior entry point for guidewire penetration in endovascular revascularization of internal carotid artery (ICA) occlusions improves procedural success. This technique aids in accessing the true lumen, facilitating treatment for cervical ICA occlusions.
Area of Science:
- Vascular Surgery
- Interventional Neurology
- Medical Devices
Background:
- Endovascular revascularization of cervical internal carotid artery (ICA) occlusions can be challenging.
- Lesion penetration is a critical step, and selecting the correct pathway is key.
Purpose of the Study:
- To evaluate the impact of initial guidewire entry point location on the success of endovascular revascularization for subacute and chronic cervical ICA occlusions.
Main Methods:
- Retrospective analysis of 11 patients undergoing endovascular revascularization for symptomatic cervical ICA occlusion.
- Guidewire penetration location (anterior vs. posterior stump) and procedural outcomes were analyzed.
Main Results:
- Eight out of 11 patients had successful revascularization.
- Anterior entry point (5 cases) resulted in smoother guidewire advancement compared to posterior entry (3 cases).
- Posterior entry was associated with guidewire advancement resistance and contrast stasis.
Conclusions:
- Targeting the anterior side of the occluded stump facilitates guidewire access to the true lumen.
- Initial anterior guidewire penetration is associated with favorable outcomes in endovascular revascularization of cervical ICA occlusions.
