[Monitoring of 4 patients with heparin-induced thrombocytopenia after complex congenital heart surgery].

From July 2013 to February 2015, 4 infant patients with complex congenital heart disease, who underwent open heart surgery in Xiangya Hospital of Central South University, were diagnosed as heparin-induced thrombocytopenia (HIT). After comprehensive treatments, such as intensive monitoring of the platelet count, close observation of thromboembolic skin lesions and close monitoring of argatroban therapy, 3 patients were cured and 1 died. HIT is rare but serious in patients who received heparin therapy. The incidence of mortality and thrombosis is very high. Early identification and diagnosis of high-risk groups can improve the prognosis.
