Patients receiving drug-eluting coronary stents (DES) require antiplatelet therapy for at least 12 months to prevent stent thrombosis (ST), a potentially calamitous event. Since interruption of antiplatelet therapy is the greatest risk factor for ST, it is imperative that the decision to discontinue these agents be based on an accurate assessment of the patient's risk for bleeding complications. Individuals who are regarded as being at a high risk are those undergoing intracranial, spinal or intraocular surgeries. These patients require alternative agents during the perioperative period to minimize both their risk of perioperative thrombosis and intraoperative hemorrhage. We report the case of a woman who required spinal surgery 3 months after she underwent placement of two drug-eluting stents. The patient's clopidogrel was stopped 5 days prior to surgery and an infusion of eptifibatide was used to "bridge" antiplatelet therapy during the perioperative period. Postoperatively, anticoagulation therapy was reinstituted using aspirin with clopidogrel. This case serves as a successful example of bridging therapy using a short acting and gycoprotein (GP) IIb/IIIa inhibitor as a means of maintaining antiplatelet therapy during the perioperative period to minimize the risk of stent thrombosis and the risk of intraoperative bleeding.
接受药物洗脱冠状动脉支架(DES)治疗的患者需要至少 12 个月的抗血小板治疗,以预防支架血栓形成(ST),这是一种潜在的灾难性事件。由于中断抗血小板治疗是 ST 的最大风险因素,因此必须根据患者出血并发症风险的准确评估来决定是否停止使用这些药物。被认为有高风险的个体是正在接受颅内、脊柱或眼内手术的患者。这些患者在围手术期需要替代药物,以最大限度地降低围手术期血栓形成和术中出血的风险。我们报告了一例在接受两个药物洗脱支架置入 3 个月后需要进行脊柱手术的女性患者。患者在手术前 5 天停止使用氯吡格雷,并在围手术期使用依替巴肽输注来“桥接”抗血小板治疗。术后,使用阿司匹林和氯吡格雷重新开始抗凝治疗。该病例成功地使用了一种短作用的糖蛋白(GP)IIb/IIIa 抑制剂作为桥接治疗,在围手术期维持抗血小板治疗,以最大程度地降低支架血栓形成的风险和术中出血的风险。
