Four patients became symptomatic 12 hours after the procedure but in one haemolysis was detected three months later. Resolution of ongoing haemolysis was achieved within 48 hours of detection with further coil implantations, but haematuria persisted for up to 10 days. In one patient the extensive destruction of erythrocytes resulted in acute renal failure requiring peritoneal dialysis.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Haemolysis is an important complication after duct coil implantation. It occurred in 3.6% of 137 procedures in this series and is most likely to occur in young patients with relatively large ducts. Further coil implantation to occlude the duct completely is not only successful but technically relatively straightforward and should be undertaken early if major complications such as severe anaemia and renal failure are to be avoided.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/hrt.81.2.160","type":"journal-article","created":{"date-parts":[[2014,10,22]],"date-time":"2014-10-22T15:31:45Z","timestamp":1413991905000},"page":"160-161","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":25,"title":["Haemolysis following implantation of duct occlusion coils"],"prefix":"10.1136","volume":"81","author":[{"given":"O","family":"Uzun","sequence":"first","affiliation":[{"name":"Department of Paediatric Cardiology, The Yorkshire Heart Centre, Leeds General Infirmary, Great George Street, Leeds LS1 3EX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G R","family":"Veldtman","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, The Yorkshire Heart Centre, Leeds General Infirmary, Great George Street, Leeds LS1 3EX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D F","family":"Dickinson","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, The Yorkshire Heart Centre, Leeds General Infirmary, Great George Street, Leeds LS1 3EX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J M","family":"Parsons","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, The Yorkshire Heart Centre, Leeds General Infirmary, Great George Street, Leeds LS1 3EX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M E C","family":"Blackburn","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, The Yorkshire Heart Centre, Leeds General Infirmary, Great George Street, Leeds LS1 3EX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J L","family":"Gibbs","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, The Yorkshire Heart Centre, Leeds General Infirmary, Great George Street, Leeds LS1 3EX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1999,2,1]]},"reference":[{"key":"2025100704352666000_81.2.160.1","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.76.3.269"},{"key":"2025100704352666000_81.2.160.2","doi-asserted-by":"crossref","first-page":"220","DOI":"10.1136\/hrt.79.3.220","article-title":"Residual and recurrent shunts after implantation of Cook detachable duct occlusion coils.","volume":"79","author":"Uzun","year":"1998","journal-title":"Heart"},{"key":"2025100704352666000_81.2.160.3","doi-asserted-by":"crossref","first-page":"450","DOI":"10.1093\/oxfordjournals.eurheartj.a015265","article-title":"Transcatheter closure of patent arterial ducts using controlled-release coils.","volume":"18","author":"Celiker","year":"1997","journal-title":"Eur Heart J"},{"key":"2025100704352666000_81.2.160.4","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.76.6.531"},{"key":"2025100704352666000_81.2.160.5","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0304(199612)39:4<410::AID-CCD19>3.0.CO;2-G"},{"key":"2025100704352666000_81.2.160.6","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0304(199611)39:3<287::AID-CCD17>3.0.CO;2-C"},{"key":"2025100704352666000_81.2.160.7","first-page":"173","article-title":"Severe intravascular haemolysis following coil occlusion of patent ductus arteriosus.","volume":"48","author":"Kapoor","year":"1996","journal-title":"Indian Heart J"},{"key":"2025100704352666000_81.2.160.8","unstructured":"Fieldman AL (1996) Crush injury, rhabdomyolysis and pigment nephropathy. in Pediatric critical care (Acute renal disease). eds Fuhrman BP Zimmerman JJ (Mosby Year Book, St Louis), pp 732\u2013734."}],"container-title":["Heart"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/hrt.81.2.160","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,7]],"date-time":"2025-10-07T11:35:34Z","timestamp":1759836934000},"score":1,"resource":{"primary":{"URL":"https:\/\/heart.bmj.com\/lookup\/doi\/10.1136\/hrt.81.2.160"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1999,2,1]]},"references-count":8,"journal-issue":{"issue":"2","published-online":{"date-parts":[[1999,2,1]]},"published-print":{"date-parts":[[1999,2,1]]}},"alternative-id":["10.1136\/hrt.81.2.160"],"URL":"https:\/\/doi.org\/10.1136\/hrt.81.2.160","relation":{},"ISSN":["1355-6037","1468-201X"],"issn-type":[{"value":"1355-6037","type":"print"},{"value":"1468-201X","type":"electronic"}],"subject":[],"published":{"date-parts":[[1999,2,1]]}}}
