Cerebral aneurysms treatment: coil embolisation

Complications

• Incomplete aneurysm occlusion
• Aneurysm recurrence
• Aneurysm re-rupture
• Delayed leukoencephalopathy
• Intra-procedural re-rupture (IPR): this increases the risks of hydrocephalus and vasospasm
• Delayed recurrent enhancing white matter lesions

Predictors for acute re-rupture (within 3 days)
