endovascular coiling
Minimally invasive treatment for cerebral aneurysms using detachable platinum coils inserted via catheter to promote aneurysm thrombosis.
Full Definition
Endovascular coiling is a neurointerventional procedure used to treat cerebral aneurysms by placing detachable platinum coils within the aneurysm sac through a catheter-based approach. The coils promote thrombosis and eventual fibrosis, effectively excluding the aneurysm from circulation while preserving the parent artery. This technique has largely replaced surgical clipping for many aneurysms due to its lower morbidity and mortality rates. Advanced techniques include balloon-assisted coiling, stent-assisted coiling, and flow-diverting devices for complex aneurysm morphologies. Post-procedural imaging surveillance is essential to monitor for coil compaction and aneurysm recurrence.
Usage
Usage note: Distinguish from other endovascular techniques when reporting.
