Thirty children who had undergone patent ductus arteriosus ligation (group 2, 9 boys and 21 girls; mean age at study, 5.7 +\/- 4.9 years; mean follow-up after ligation, 44 +\/- 58 months) were evaluated in the same way. The prevalence of residual ductal shunting and the main pulmonary arterial flow patterns were recorded. Residual ductal shunting in group 1 was 38% on day 1, decreasing slowly to 31% at 3 months, 27% at 6 months, and 19.7% at 1 year or more due to further spontaneous shunt resolution. The residual shunting rate in group 2 (6%) was significantly lower than that at 1 year or more in group 1 (p less than 0.001). Successful reocclusion in 5 of 6 in a subset of patients in group 1 followed for 1 year or less reduced further the prevalence of residual shunting. Residual shunting after patent ductus arteriosus occlusion is more common than after ligation, but continues to decrease during follow-up.<\/jats:p>","DOI":"10.1161\/01.cir.80.6.1706","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T16:29:13Z","timestamp":1308328153000},"page":"1706-1710","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":73,"title":["Two-dimensional echocardiographic and color flow Doppler evaluation of ductal occlusion with the Rashkind prosthesis."],"prefix":"10.1161","volume":"80","author":[{"given":"N N","family":"Musewe","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Hospital for Sick Children, Toronto, Ontario, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L N","family":"Benson","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Hospital for Sick Children, Toronto, Ontario, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J F","family":"Smallhorn","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Hospital for Sick Children, Toronto, Ontario, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R M","family":"Freedom","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Hospital for Sick Children, Toronto, Ontario, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","container-title":["Circulation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ahajournals.org\/doi\/pdf\/10.1161\/01.CIR.80.6.1706","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T12:06:36Z","timestamp":1715515596000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.CIR.80.6.1706"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1989,12]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[1989,12]]}},"alternative-id":["10.1161\/01.CIR.80.6.1706"],"URL":"https:\/\/doi.org\/10.1161\/01.cir.80.6.1706","relation":{},"ISSN":["0009-7322","1524-4539"],"issn-type":[{"value":"0009-7322","type":"print"},{"value":"1524-4539","type":"electronic"}],"subject":[],"published":{"date-parts":[[1989,12]]},"assertion":[{"value":"1989-12-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
