Embolization of wide-necked aneurysms with using three or more microcatheters

Area of Science:

• Neurosurgery
• Endovascular Therapy
• Cerebrovascular Diseases

Background:

• Cerebral aneurysms, particularly wide-necked ones, pose treatment challenges.
• Endovascular techniques are evolving for improved aneurysm management.

Purpose of the Study:

• To describe a new endovascular technique using multiple microcatheters for treating wide-necked cerebral aneurysms.
• To evaluate the safety and efficacy of this novel approach.

Main Methods:

• A series of eight patients with wide-necked cerebral aneurysms were treated using a multiple microcatheter technique with detachable coils.
• Three to four microcatheters were employed for coil delivery and stabilization within the aneurysm sac.
• Coils were deployed and intermingled to create a stable mass, followed by detachment.

Main Results:

• Successful treatment of all eight wide-necked aneurysms without any complications.
• Post-treatment angiography demonstrated 100% occlusion in five cases and a minimal residual neck in three cases.
• No procedure-related complications were observed.

Conclusions:

• The multiple microcatheter technique is a viable and safe technical option for the endovascular treatment of wide-necked cerebral aneurysms.
• This approach facilitates effective coil packing and stabilization in complex aneurysm anatomies.
