Cangrelor is an intravenous P2Y12 receptor inhibitor with a rapid onset/offset of action and a short half-life (3-6 min). The objective was to present a preliminary experience regarding the safety and effectiveness using cangrelor, in combination with aspirin, in acute ischemic stroke patients requiring acute stenting.
Retrospective analysis for patients who underwent stenting (intracranial and/or extracranial) in the setting of acute ischemic stroke with cangrelor and aspirin as antiplatelet therapy.
Cangrelor was used in 12 patients, 4 (33%) with extracranial stenting, 6 (50%) with intracranial stenting and 2 (17%) with combined extracranial and intracranial stenting. The mean age was 67 years (44-88) and 9 patients (75%) were female. The median National Institutes of Health Stroke Score at admission was 15 (IQR: 8-22). Of the patients, six (50%) received intravenous thrombolysis. All patients (100%) obtained modified thrombolysis in cerebral infarction score ≥2b. Good clinical outcome, defined as modified Rankin scale score ≤2 at 3‑months follow-up, was observed in 7 patients (58%). None of the patients experienced intraprocedural thromboembolic complications. Postprocedural stent thrombosis after cessation of cangrelor infusion due to emergency craniotomy surgery to manage malignant cerebral infarction occurred in one patient (8%). Of the patients, two (17%) experienced asymptomatic intracranial hemorrhage (ICH), one patient (8%) experienced symptomatic ICH and one (8%) retroperitoneal hematoma was observed, which was managed conservatively.
Cangrelor might be a safe and effective antiplatelet medication owing to its on/off activity for acute stenting in the setting of acute ischemic stroke. Further investigations through randomized studies with larger samples are necessary.
坎格雷洛是一种静脉内 P2Y12 受体抑制剂,具有快速起效/消除作用和较短的半衰期(3-6 分钟)。本研究旨在介绍在需要急性支架置入的急性缺血性脑卒中患者中,联合应用坎格雷洛和阿司匹林的安全性和有效性的初步经验。
回顾性分析了接受支架置入术(颅内和/或颅外)的急性缺血性脑卒中患者,这些患者接受了坎格雷洛和阿司匹林作为抗血小板治疗。
12 例患者使用了坎格雷洛,其中 4 例(33%)接受了颅外支架置入术,6 例(50%)接受了颅内支架置入术,2 例(17%)接受了颅外和颅内联合支架置入术。平均年龄为 67 岁(44-88 岁),9 例(75%)为女性。入院时的国立卫生研究院卒中量表中位数为 15 分(IQR:8-22)。其中 6 例(50%)患者接受了静脉溶栓治疗。所有患者(100%)均获得改良脑梗死溶栓评分≥2b。7 例(58%)患者在 3 个月随访时获得良好的临床转归(改良 Rankin 量表评分≤2)。1 例(8%)患者因恶性脑梗死行紧急开颅手术而停止输注坎格雷洛后出现术后支架内血栓形成。2 例(17%)患者出现无症状性颅内出血(ICH),1 例(8%)患者出现症状性 ICH,1 例(8%)患者出现腹膜后血肿,均保守治疗。
由于坎格雷洛具有快速起效/消除作用,因此在急性缺血性脑卒中患者中进行急性支架置入时,可能是一种安全有效的抗血小板药物。需要通过更大样本量的随机研究进一步证实。
