Prosthetic valve thrombosis, although rare, is a life-threatening complication of valve replacement surgery. The authors present an atypical case of a modified Bentall procedure with the CarboSeal Valsalva™ conduit complicated by an early mechanical prosthetic aortic valve thrombosis and coronary embolism. The patient was successfully treated with an emergency percutaneous coronary angioplasty and intracoronary thrombus aspiration of the left anterior descending artery, followed by a systemic 10 mg bolus of tissue plasminogen activator followed by ultraslow (25 h) infusion of low-dose (25 mg), while supported with venoarterial extracorporeal membrane oxygenation.
人造瓣膜血栓形成虽然罕见,但却是瓣膜置换手术后危及生命的并发症。作者介绍了一例采用改良 Bentall 手术和 CarboSeal Valsalva™ 导管的不典型病例,该手术出现早期机械性人造主动脉瓣血栓形成和冠状动脉栓塞。该患者通过紧急经皮冠状动脉成形术和左前降支冠状动脉内血栓抽吸术成功治疗,随后全身给予 10mg 组织型纤溶酶原激活剂(tissue plasminogen activator)冲击量,随后以超慢(25 小时)输注低剂量(25mg),同时辅以静脉-动脉体外膜肺氧合(venoarterial extracorporeal membrane oxygenation)。
