Thrombocytopenia in Pediatric Congenital Heart Diseases Patient with the Transcatheter Closure

Background: Postoperative thrombocytopenia with congenital heart disease (CHD) after percutaneous transcatheter closure (PTC) has seldom been reported. We sought to investigate the treatments, severity and causes of postoperative thrombocytopenia among patients with CHD undergoing PTC.Methods: Six PTC patients undergoing postoperative thrombocytopenia in our department were included. Platelet count was measured at admission and daily after PTC at least for day 9.Results: Three patients had platelet counts below 30×10^9 /L while in the other two patients the counts were below 50×10^9 /L. All patients achieved a stable platelet count, ranging from 99×10^9 /L to 241×10^9 /L after day 9. The platelet counts recovered after being given intravenously the methylprednisolone (two patients), immunoglobulin (one patient) and platelet transfusions (two patients). During the whole course, the face and limbs of one patients were visible ecchymosis but no major bleeding events were recorded.Conclusion: In this report, the clinical outcome of our patients were satisfactory; they complaints regressed after above treatment.
