Abstract:
Objective To compare the clinical efficacy of intraoperative intravenous tirofiban versus preoperative loading dose dual antiplatelet therapy in the acute phase LVIS stent-assisted coil embolization treatment for ruptured wide-necked intracranial aneurysms.Methods Patients with acutely ruptured,wide-neck intracranial aneurysms underwent LVIS stent-assisted coil embolization in the Department of Neurosurgery at Heze Municipal Hospital were retrospectively and consecutively enrolled from January 2017 to June 2023.According to the Chinese expert consensus on antiplatelet therapy for intracranial aneurysms,patients were divided into two groups based on the types of antiplatelet therapy they received:the loading-dose dual antiplatelet therapy(DAPT)group and the tirofiban group.Baseline and clinical data were collected and compared between the two groups,including age,sex,hypertension,diabetes mellitus,coronary artery disease,history of cerebral hemorrhage,preoperative Hunt-Hess grade,maximum aneurysm diameter,aneurysm neck width,and aneurysm location.Perioperative ischemic and hemorrhagic complications were collected and compared between the two groups.Perioperative ischemic complications included:intraoperative stent thrombosis(defined as filling defects in the parent artery,and,occlusion of the parent artery or stented branch during the procedure),and symptomatic ischemic infarction within 24 h postoperatively(confirmed by imaging with corresponding neurological deficits).Perioperative hemorrhagic complications included:intraoperative rupture of the target aneurysm(contrast extravasation or acute hemorrhage during embolization)and intracranial hemorrhage within 24 h postoperatively(new or worsened subarachnoid hemorrhage or intraparenchymal hemorrhage on CT).Clinical outcomes at 90 days were collected via telephone or outpatient follow-up,and evaluated using favorable prognosis defined as modified Rankin scale(mRS).A mRS score of 0-2 were defined as favorable prognosis and 3-6 as poor prognosis.Six-month postoperative imaging follow-up were collected,angiographic outcomes were categorized into four groups based on comparison with immediate post-embolization results:complete occlusion,total absence of contrast filling in the aneurysm sac;improved,reduced contrast filling;stable,unchanged contrast filling;and,recurrence,increased contrast filling.Results Totals of 108 patients with intracranial aneurysms treated by LVIS stent-assisted coiling were enrolled,with 30 males and 78females,aged32-75years(median age63[50,66]years).Among the108cases,55cases were assigned into the DAPT group,and 53 cases were included in the tirofiban group.(1)No statistically significant differences were observed between the tirofiban group and the DAPT group in baseline and clinical characteristics(all P＞0.05).(2)All patients underwent successful LVIS stent-assisted coiling,with a technical success rate of 100%.The total perioperative ischemic complications were 12.0%(13/108),including 4.6%(5/108)intraoperative stent thrombosis and 7.4%(8/108)symptomatic ischemic infarction within 24h after surgery.The total perioperative hemorrhagic complications rate was 1.9%(2/108),including 1 case of intraoperative aneurysm rupture and 1 case of postoperative intracranial hemorrhage within24h.92.6%(100/108)of the patients exhibited favorable prognosis and 7.4%(8/108)showed poor prognosis at the 90-day follow-ups.78.7%(85/108)of the patients accomplished at 6-month imaging follow-ups,the complete occlusion ratio was 94.1%(80/85)and the recurrence ratio was 2.4%(2/85).(3)The overall perioperative ischemic complication rates were 13.2%(7/53)in the tirofiban group and 10.9%(6/55)in the DAPT group,with no statistically significant difference(P=0.720).Intraoperative stent thrombosis occurred more frequently in the DAPT group(9.1%[5/55]vs.0,P=0.025),while symptomatic ischemic infarction within 24 h post-procedure was lower in the DAPT group(1.8%[1/55]vs.13.2%[7/53],P=0.028).The hemorrhagic complications occurred only in the DAPT group,with a rate of 3.6%(2/55),while no events observed in the tirofiban group.At the 90-day follow-up,the proportion of patients with favorable outcomes was 94.3%(50/53)in the tirofiban group and 90.9%(50/55)in the DAPT group,with no statistically significant difference between the groups(P=0.754).Conclusions Both intraoperative intravenous tirofiban and preoperative loading-dose DAPT demonstrated comparable safety profile and favorable clinical efficacy in the acute-phase treatment of ruptured wide-necked intracranial aneurysms with LVIS stent-assisted coil embolization.The results require further validation through large-scale prospective studies.
