RESUMO
Objective To report one case of the children's acute rhabdomyolysis(RM) with myocardial hypertrophy for the first time and the related data in order to improve the clinical diagnose and the treatment efficacy.Methods Clinical data of the patient with myocardial hypertrophy and pericardial effusion treated in the Heart Center of Beijing Children's Hospital Affiliated to Capital Medical University were retrospectively analyzed.According to the symptoms,signs,laboratory examination,the diagnosis was made and related literature was reviewed.Results A 7-years-old girl was characterized by myalgia,weakness,and dark urine.Physical examination showed extremity swelling,clammy skin,lower extremity muscle tenderness positive.Creatine kinase (CK) and myoglobin levels increased.So she was clearly diagnosed of acute RM undoubtedly.Without physical,metabolic and autoimmune factors,the patient was only had positive mycoplasma antibodies and might be coursed by mycoplasma infection.The muscular involvement was so severe that the patient had the heart failure,myocardial hypertrophy and pericardial effusion was conformed to ultrasound cardiogram(UCG).After treatment with hydration,alkalization,anti-infection,support and symptomatic therapy for a few days,the clinical symptoms improved obviously,CK returned to normal,myocardial hypertrophy and pericardial effusion disappeared.One-year-follow-up study indicated that the child's animal force and body movements were norrmal,and CK and UCG were negative.Conclusions Acute RM is a rare disorder and less recognized in children,and myocardial hypertrophy and pericardial effusion may be caused by acute RM.If the diagnosis and treatment are done earlier,the prognosis will be good,without permanent complications.
RESUMO
Intracardial thrombus in children is induced by multiple etilolgies. The most common reasons are chronic heart failure and restrictive cardiomyopathy. Intracardial thrombus lack specific symptom and sign. More than 90% intracardial thrombus of left heart are localized at apex. The two-dimensional echocardiogramgram, especially transesophageal echocardiography and heart computer scan are the common methods to check out intracardial thrombus. The therapy of intracardial thrombus include anticoagulation, thrombolysis and operation. This review summarized recent studies about intracardial thrombus in terms of etiology, diagnosis and treatments.
