Safety and Efficacy Analysis of Stent-assisted Coil Embolization in the Treatment of Acute Ruptured Intracranial Aneurysms in the Perioperative Period.

To determine the perioperative safety and efficacy of stent-assisted coil embolization of intracranial aneurysms in the acute phase. Intravenous antiplatelet drugs that are clinically easy to administer, have good reproducibility and good controllability are used.The program focuses on exploring the safety of emergency stent-assisted embolization of intracranial wide carotid aneurysms, and then determines the effectiveness of treatment in preventing rebleeding and preventing aneurysm recurrence in the long term.

Inclusion Criteria: * Patients aged 18-80 with a single ruptured cystic aneurysm at the center, or multiple aneurysms with a clear responsible lesion, only treat the responsible lesion * Aneurysms with a wide neck, neck ≥4mm, or neck/body ratio \>1/2 * Treatment performed within 7 days of the last hemorrhage * Patients undergoing interventional treatment using a stent, including cases of remedial stent use.5. Hunt \& Hess grade 1-3 Exclusion Criteria: * Exclude patients who meet the inclusion criteria but fail to undergo successful SAC embolization * Exclude non-cystic aneurysms, such as dissection, pseudoaneurysm, and distal aneurysm patients * Patients with other cerebrovascular diseases, including AVM, DAVF, Moyamoya disease, and arterial stenosis greater than 50% * Patients unable to use intravenous antiplatelet drugs * Patients with poor condition prior to aneurysm rupture, mRS ≥ 2 * Exclude pregnant patients * Exclude patients with other severe preoperative diseases, such as malignant tumors or cardiopulmonary and renal diseases * Patients with multiple aneurysms where the responsible lesion cannot be identified and treatment is done for all
