Single-Center Experience with the Optiblock Coil: An Efficient and Thrombogenic Solution for Targeted Vessel Takedown

Area of Science:

• Neurosurgery
• Interventional Radiology
• Vascular Surgery

Background:

• Coil technology traditionally focuses on aneurysm occlusion.
• Optiblock coils offer a volumetric system for targeted vessel takedown.
• These coils feature extended lengths and an anchor-basket-fill design for enhanced packing and thrombogenicity.

Purpose of the Study:

• To evaluate the safety, efficiency, and versatility of Optiblock coils.
• To assess their use in non-aneurysmal neurointerventional procedures.
• To analyze procedural characteristics and safety outcomes.

Main Methods:

• Single-center, retrospective study of 95 patients.
• Embolization procedures using Optiblock coils between March 2023 and December 2024.
• Indications included dural arteriovenous fistulas, internal maxillary artery embolization, venous diverticulum embolization, parent vessel sacrifice, middle meningeal artery embolization, and tumor feeder embolization.

Main Results:

• Mean age 56 years; 53% female; 62% transarterial approaches.
• Median of 5 coils used per procedure (mean total length 56 cm).
• No intraoperative or delayed complications; 4.2% mortality unrelated to procedure.

Conclusions:

• Optiblock coils show a favorable safety profile.
• Demonstrated technical versatility for vessel occlusion.
• Effective across diverse non-aneurysmal indications in this initial series.
