Superselective coaxial microballoon-occluded coil embolization for vascular disorders: a preliminary report

Area of Science:

• Interventional Radiology
• Vascular Surgery
• Medical Devices

Background:

• Vascular disorders present complex treatment challenges.
• Minimally invasive techniques are increasingly preferred for vascular interventions.

Purpose of the Study:

• To evaluate the safety and effectiveness of superselective coil embolization with coaxial microballoon occlusion (B-coiling).
• To assess B-coiling as a treatment for diverse vascular disorders.

Main Methods:

• Retrospective analysis of 16 patients undergoing B-coiling for conditions including aneurysms, arteriovenous malformations (AVMs), and varices.
• Utilized 0.010-0.014-inch detachable microcoils delivered via microballoon catheter.

Main Results:

• Complete primary occlusion was achieved in 87.5% (14/16) of patients without complications.
• Successful adjunctive treatments included transhepatic sclerotherapy and balloon-occluded injection for specific cases.

Conclusions:

• Superselective coaxial microballoon embolization with detachable microcoils is a safe and effective therapeutic option.
• B-coiling facilitates controlled, tight packing of coils for treating vascular disorders.
