Endovascular coils: properties, technical complications and salvage techniques

Area of Science:

• Neurosurgery
• Interventional Radiology

Background:

• Endovascular coil embolization is a primary treatment for intracranial aneurysms.
• Existing literature extensively covers general complications of endovascular therapy.
• Fewer reports focus specifically on technical and device-related complications of coiling.

Purpose of the Study:

• To review structural details of commonly used endovascular coils.
• To discuss technical complications encountered during coil deployment.
• To outline salvage techniques for managing coiling-related complications.

Main Methods:

• Literature review of endovascular coil embolization for intracranial aneurysms.
• Analysis of structural characteristics of various embolic coils.
• Examination of reported technical complications and their resolutions.

Main Results:

• Detailed examination of coil structures provides insight into potential failure modes.
• Common technical complications include coil migration, incomplete filling, and rupture.
• Effective salvage techniques exist for managing deployment-related issues.

Conclusions:

• Understanding coil structure and deployment nuances is crucial for minimizing complications.
• Prompt recognition and application of salvage techniques can improve patient outcomes.
• Further research into device innovation and standardized techniques is warranted.
