Surgical complications occurred in 8.7% (8\/92), which included pneumothorax (5\/8), recurrent laryngeal nerve palsy (2\/8), and chylothorax (1\/8). Morbidity outcome data were not available for all infants. The incidence of chronic lung disease was 88% (88\/99); intraventricular haemorrhage was 49% (49\/100); necrotising enterocolitis 39% (39\/99), and retinopathy of prematurity 42% (41\/97). The overall mortality rate in our study was 7.8% (8\/102). Mortality rate in infants who had patent ductus arteriosus ligation was 4.3% (4\/92). The 30-day survival rate after ligation was 99% (91\/92). Beyond 30 days post-ligation, three infants died from other causes that were not directly related to surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1047951112001795_abs4\" sec-type=\"conclusion\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Patent ductus arteriosus ligation in premature infants is associated with low mortality and complication rates; however, there is a high incidence of neonatal morbidity. Surgical capacity for patent ductus arteriosus ligation needs to be carefully planned nationally as the duration of \u201cwaiting time\u201d and transport to another surgical centre could adversely affect outcomes in this high-risk population.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1017\/s1047951112001795","type":"journal-article","created":{"date-parts":[[2012,11,20]],"date-time":"2012-11-20T08:44:18Z","timestamp":1353401058000},"page":"711-716","source":"Crossref","is-referenced-by-count":19,"title":["Outcome of patent ductus arteriosus ligation in premature infants in the East of England: a prospective cohort study"],"prefix":"10.1017","volume":"23","author":[{"given":"Sok-Leng","family":"Kang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salehuddin","family":"Samsudin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minju","family":"Kuruvilla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anshoo","family":"Dhelaria","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sue","family":"Kent","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wilfred A.","family":"Kelsall","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2012,11,20]]},"reference":[{"key":"S1047951112001795_ref35","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3468(93)90148-E"},{"key":"S1047951112001795_ref6","doi-asserted-by":"publisher","DOI":"10.1159\/000087582"},{"key":"S1047951112001795_ref34","doi-asserted-by":"publisher","DOI":"10.1136\/fn.85.2.F114"},{"key":"S1047951112001795_ref25","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2010.206052"},{"key":"S1047951112001795_ref17","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(78)80910-X"},{"key":"S1047951112001795_ref15","doi-asserted-by":"crossref","unstructured":"Herrera C , Holberton J , Davis P .
