Introduction
The ductus arteriosus connects the main pulmonary arteries and the aortic arch and always closed within 2 days of birth1. If the ductus remains open, then it is called patent ductus arteriosus. PDA occur around 5% to 10% in all congenital heart disease where the male to female ratio is 1 to 32. We categorized treatment of PDA to two groups: drug induction and external assistant. Drug induction insisted of intravenous injection of indomethacin or ibuprofen and external assistant insisted of transcatheter coil occlusion or surgical ligation. Treatments lead to high recovery rate and we are interested in evaluating the publication pattern of treatment related documents and to denote any significant patterns.
Methodology
Documents were
Extracted from Science Citation Index (SCI)
Published from 1981 to 2002
Drug induction included keywords: indomethacine or ibuprofen
External assistant included keywords: coil or surgical ligation
Results
Document Type distribution of two treatment categories were very different
External assistance documents were published in three other language beside English where drug induction documents just in one other language
Document Type
External Assistance
Drug Induction

Conclusion
Steady yearly publication of external assistance suggest satisfaction with present method or communications were conducted but not indexed by SCI
Drug induction total production was very minute compare to PDA and the other
Treatment documents production dominated by different countries but both were main-stream countries
Indicated English was the most often language used in Science Research
Suggested small group collaboration was often
International Collaboration was not popular
