The treatment of intracranial aneurysms mainly includes microsurgical clipping and endovascular interventional embolization. With the continuous development of interventional medicine technology, endovascular intervention for intracranial aneurysm is the mainstream treatment method, which is more adaptable, less traumatic and faster recovery than microsurgical clipping, but the possibility of perioperative thrombosis still exists. In this paper, we review the mechanism of perioperative thrombosis, prevention and noninvasive monitoring of intracranial aneurysm interventions 【Key words】 Intracranial aneurysm;Intervention;Perioperative period;Thrombosis
