1Department of Neurological Surgery, Wakayama Medical College; Wakayama, Japan.
Summary
Electrically detachable coils safely treated intracranial aneurysms in 19 patients. While effective, careful attention is needed for wide-necked, small, or complex aneurysms to ensure complete occlusion.
Area of Science:
- Neurosurgery
- Interventional Neuroradiology
- Vascular Neurology
Background:
- Intracranial aneurysms pose significant risks, necessitating effective treatment options.
- Endovascular coiling offers a minimally invasive approach to aneurysm management.
Purpose of the Study:
- To evaluate the safety and efficacy of electrically detachable coils for intracranial aneurysm treatment.
- To assess angiographic outcomes and complication rates associated with this technique.
Main Methods:
- Nineteen patients with intracranial aneurysms were treated using electrically detachable coils (GDC or IEDC).
- Angiographic results, including occlusion rates and neck remnants, were assessed.
- Complications such as hemorrhage and thromboembolism were monitored.
Main Results:
- Complete occlusion was achieved in 11 of 18 treated aneurysms (61%).
- Neck remnants occurred in 17% and dome filling in 22% of cases.
- No hemorrhagic or thromboembolic complications were observed in the 19 patients.
Conclusions:
- Electrically detachable coil embolization is a safe and useful procedure for intracranial aneurysms.
- Careful consideration is required for wide-necked, small (<3mm), or complex-shaped aneurysms to prevent incomplete occlusion.
