Summary
A new technique using a soft coil and microcatheter allows for super-selective embolization in complex neurovascular cases. This method proved safe and effective for treating intracranial aneurysms, AVMs, AVFs, and tumors.
Area of Science:
- Interventional Neuroradiology
- Vascular Surgery
- Neurosurgery
Background:
- Endovascular coil embolization is a key treatment for intracranial vascular lesions.
- Navigating microcatheters in small, tortuous vessels presents a significant challenge.
Purpose of the Study:
- To present a novel technique for super-selective coil embolization.
- To evaluate the safety and efficacy of using a specific soft coil and microcatheter system.
Main Methods:
- A case series involving 16 patients with various intracranial vascular pathologies.
- Utilized the Marathon® liquid embolic delivery microcatheter and ED extrasoft® coils.
- Achieved coil embolization in target lesions within tiny, tortuous vessels.
Main Results:
- Successful super-selective coil embolization was achieved in all 16 patients.
- The treated conditions included arteriovenous malformations (AVMs), distal aneurysms, dural arteriovenous fistulas (AVFs), and meningiomas.
- The technique demonstrated safe and efficient delivery of coils even in challenging anatomy.
Conclusions:
- The described technique enables safe and efficient super-selective coil embolization.
- This method is particularly beneficial for treating complex intracranial vascular lesions in tortuous vessels.
- The combination of the Marathon® catheter and ED extrasoft® coils offers a valuable option for interventional neuroradiology.
