Real time CEUS was performed after a bolus injection of SonoVue\n                    <jats:sup>\u00ae<\/jats:sup>\n                    (1.6\u20132.4 ml, Bracco, Imaging Germany) followed by 10 ml of saline solution. Using contrast harmonic imaging (CHI) technique (Logiq 9, GE) with a 2.5\u20134-MHz transducer, a low mechanical index was chosen to avoid early destruction of the microbubbles (MI 0.1\u20130.2). In order to confirm the results, the patients underwent contrast-enhanced MRI or CT.\n                  <\/jats:p>\n                  <jats:p>Results: Complications were identified in 16 of 36 patients (44.4%). Five transplants (14%) had hepatic artery thrombosis (n=2) or significant stenosis (n=3). Six transplants (16%) developed portal vein stenosis (n=4) or portal vein thrombosis (n=2). MRI or CT confirmed the findings of the CEUS in all 11 cases. Biliary stricture at the anastomotic site was detected in 5 patients. MR-CP confirmed the findings of all strictures.<\/jats:p>\n                  <jats:p>Conclusion: Due to advances in contrast-enhanced US, vascular and biliary complications in the postoperative period following liver transplantation can be reliably diagnosed non-invasively on the intensive care unit. CEUS shows vascular as well as biliary complications in the postoperative patient with a high degree of accuracy.<\/jats:p>","DOI":"10.3233\/ch-2009-1223","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T13:01:50Z","timestamp":1575291710000},"page":"83-94","source":"Crossref","is-referenced-by-count":21,"title":["Contrast-enhanced ultrasound in liver transplant: First results and potential for complications in the postoperative period"],"prefix":"10.1177","volume":"43","author":[{"given":"D.-A.","family":"Clevert","sequence":"first","affiliation":[{"name":"Department of Clinical Radiology, University Hospitals \u2013 Grosshadern, Ludwig-Maximilians-University, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Stickel","sequence":"additional","affiliation":[{"name":"Department of Surgery, Klinikum Grosshadern, University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Minaifar","sequence":"additional","affiliation":[{"name":"Department of Clinical Radiology, University Hospitals \u2013 Grosshadern, Ludwig-Maximilians-University, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"L\u00f6he","sequence":"additional","affiliation":[{"name":"Department of Surgery, Klinikum Grosshadern, University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Graeb","sequence":"additional","affiliation":[{"name":"Department of Surgery, Klinikum Grosshadern, University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.W.","family":"Jauch","sequence":"additional","affiliation":[{"name":"Department of Surgery, Klinikum Grosshadern, University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Reiser","sequence":"additional","affiliation":[{"name":"Department of Clinical Radiology, University Hospitals \u2013 Grosshadern, Ludwig-Maximilians-University, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,1]]},"container-title":["Clinical Hemorheology and Microcirculation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/CH-2009-1223","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/CH-2009-1223","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T15:08:06Z","timestamp":1777388886000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/CH-2009-1223"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,1]]},"references-count":0,"journal-issue":{"issue":"1-2","published-print":{"date-parts":[[2009,10]]}},"alternative-id":["10.3233\/CH-2009-1223"],"URL":"https:\/\/doi.org\/10.3233\/ch-2009-1223","relation":{"is-cited-by":[{"id-type":"doi","id":"10.3748\/wjg.v22.i4.1607","asserted-by":"object"},{"id-type":"doi","id":"10.3748\/wjg.v22.i4.1617","asserted-by":"object"}]},"ISSN":["1386-0291","1875-8622"],"issn-type":[{"value":"1386-0291","type":"print"},{"value":"1875-8622","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,1]]}}}
