Part I: the thrombus was treated by the pulse-spray technique (PT) (urokinase 250,000 IU; n=7) or a rotatory basket catheter, Thrombolizer (MT) (activated with compressed air at 7 atm; n=5). Part II: Following placement of a Spring filter, the animal underwent PT (n=5) or MT (n=5). Based on the results of part I, the treatment protocol was modified (PT, urokinase 500,000 IU; MT, compressed air at 8 atm). Embolus volumes trapped by the filter and found in the lungs were calculated and the filtering efficacy quantified.<\/jats:p>\n                  <jats:p>Results: Part I: Pulmonary emboli (1 to 4 mm in diameter) were observed in 3 animals in the PT group and 1 animal in the MT group, respectively. Median reduction in thrombus volume was 21% and 4% by PT and MT, respectively. Part II: In the PT group, 58% and 100% of the total embolus load was trapped in 2 animals, while the filter failed to trap emboli (1 to 1.5 mm in diameter) in 1 animal. In the remaining 2 animals, no embolus was found trapped by the filter or in the lungs. In the MT group, 55\u201397% (median 83%) of the embolus load was trapped. Emboli found in the lungs did not exceed 4 mm in diameter.<\/jats:p>\n                  <jats:p>Conclusion: Preceding interventional treatment of venous thrombosis with placement of the Spring filter reduced the embolic burden on the lungs.<\/jats:p>","DOI":"10.3109\/02841859909175582","type":"journal-article","created":{"date-parts":[[2009,10,1]],"date-time":"2009-10-01T16:19:43Z","timestamp":1254413983000},"page":"545-551","source":"Crossref","is-referenced-by-count":5,"title":["Placement of a Spring Filter during Interventional Treatment of deep Venous Thrombosis to Reduce the Risk of Pulmonary Embolism"],"prefix":"10.1177","volume":"40","author":[{"given":"J.","family":"Hosaka","sequence":"first","affiliation":[{"name":"Section for Experimental Radiology, Institute for Surgical Research, the National Hospital, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Roy","sequence":"additional","affiliation":[{"name":"Section for Experimental Radiology, Institute for Surgical Research, the National Hospital, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Kuroki","sequence":"additional","affiliation":[{"name":"Section for Experimental Radiology, Institute for Surgical Research, the National Hospital, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Z.","family":"Xian","sequence":"additional","affiliation":[{"name":"Section for Experimental Radiology, Institute for Surgical Research, the National Hospital, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Kvernebo","sequence":"additional","affiliation":[{"name":"Department of Surgery, Ullev\u00e5l Hospital, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"Enge","sequence":"additional","affiliation":[{"name":"Section for Experimental Radiology, Institute for Surgical Research, the National Hospital, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"L\u00e6rum","sequence":"additional","affiliation":[{"name":"Section for Experimental Radiology, Institute for Surgical Research, the National Hospital, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1999,9,1]]},"container-title":["Acta Radiologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3109\/02841859909175582","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3109\/02841859909175582","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:44:29Z","timestamp":1777383869000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3109\/02841859909175582"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1999,9]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[1999,9]]}},"alternative-id":["10.3109\/02841859909175582"],"URL":"https:\/\/doi.org\/10.3109\/02841859909175582","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[1999,9]]}}}
