Analysis of infective endarteritis in patent ductus arteriosus.

This study reports on infective endarteritis in 14 children with patent ductus arteriosus over a period of 6 years. Infective endarteritis mostly involved the small ducts and was previously undiagnosed. These patients were given antibiotic treatment for a variable period of 4 to 10 weeks, and all except 1 underwent subsequent closure.
