Clinical characteristics and therapy of Kawasaki disease with giant coronary artery and thrombosis / 中华实用儿科临床杂志

ABSTRACT

Objective To summarize the clinical characteristics of children with coronary artery aneurysms (CAA) and thrombosis in Kawasaki disease (KD),in order to explore the safe and effective thrombolytic therapy and its prognosis.Methods The clinic,treatment and follow-up data of 210 patients with KD between January 2006 and December 2016 were retrospectively reviewed in the Department of Pediatrics,Union Hospital,Tongji Medical College,Huazhong University of Science and Technology.The clinic signs and laboratory data for CAA with thrombosis were analyzed.The characteristics of CAA were monitored by tltrasound.All KD patients with thrombus received intravenous antithrombotic therapy,including urokinase,heparin,and oral Warfarin,and anti-platelet treatment.The effectiveness of antithrombotic treatment was evaluated by measuring the ability to dissolve the thrombus.Results Fourteen cases in 210 patients with KD developed CAA,and had associated thrombosis.In these 14 patients,the largest diameter of CAA was 18.5 mm,and the average value was 12.6 mm.There was no special blood analysis in CAA with thrombus.Moreover,typical KD symptoms and acute myocardial infarction were not found in CAA with thrombosis.Thrombus occurred in giant aneurysms,and 2 patients had multiple thrombosis.After thrombolytic therapy,12 cases in the 14 patients had successful thrombolysis,2 patients had thrombus organization and coronary artery stenosis.Conclusions Neither clinical features nor laboratory data could reliably predict CAA associated thrombosis.Thrombus was easily formed in giant CAA.Frequent and periodly follow-up are important to detect thrombosis in KD patients with giant coronary artery.Therapy with adequate intravenous antithrombotic therapy and anti-platelet treatment earlier can effectively dissolve thrombus in KD patients,and avoid deterioration.
