Objective To investigate the incidence, clinical features of pulmonary embolism (PE) secondary to nephrotic syndrome(NS) in Chinese children.Methods Pulmonary perfusion imaging (PPI) and chest radiography was performed on 20 NS patients with elevated plasma D dimer. The patients with PE were given anticoagulative therapy with heparin and persantine.Results Among 20 NS patients, eight cases, aged from 5 to 12 years, 6 boys and 2 girls, were found to have PE. Of them 5 were primary NS and 3 were secondary NS. PPI showed an involvement of 1 pulmonary segment in 3 cases, of 2 pulmonary segments in 2, of 3 pulmonary segments in 2 ,and of 6 pulmonary segments in 1. Most patients did not present clinical signs and symptoms. Two weeks after the administration of intravenous heparin for anticoagulative therapy, 6 out of 8 cases showed a recovery or an improvement. Conclusion The results of this study suggest that PE be not a rare complication in NS children. Most patients had no obvious clinical manifestation and their prognose was favorable if diagnosed and treated in time.
