Coronary Artery Bypass Grafting In Patients With Essential Thrombocythemia

[Objective]The purpose of this study was to summarize the available literature and provide experience for patients with essential thrombocythemia undergoing coronary artery bypass grafting.[Methods]Combined with an ET case in our hospital,a systematic literature search was conducted in the databases such as CNKI,Wanfang Data,CQVIP,SinoMed and PUBMED to retrieve relevant documents and extract information.[Results]A total of 25 patients in 15 relevant case reports were ultimately enrolled,including 19 males and 6 females.CABG in 21 cases,AVR+CABG in 4 cases,Severe postoperative complications occurred in 5 patients,of which 4 of 5 had an immediate preoperative platelet count of 800 × 109/L or higher,Left ventricular assist device was implanted and heart transplantation was performed in 1 case,1 case died of ventricular fibrillation and cardiac arrest.[Conclusions]patients with ET undergoing cardiac surgery are at risk of perioperative thrombosis or bleeding complications or both,Perioperative management should include antiplatelet therapy,prophylaxis of thrombus and myocardial revascularization.
