The purpose of the study is using a laser Doppler imaging device (Easy\u2010LDI) as an additional tool to assess perfusion. In this method, the changes in the frequency of the laser ligth provide information regarding perfusion of the monitored tissue.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and Methods<\/jats:title><jats:p>This study included seven patients (10 fingers; age of patients: 21\u201357 years) who suffered from a total (<jats:italic>n<\/jats:italic>\u2009=\u20096) or subtotal amputation (<jats:italic>n<\/jats:italic>\u2009=\u20094) due to accidents.

The mean LDI values before and after revascularization were 7.1\u2009\u00b1\u20092.85 and 65.30\u2009\u00b1\u200930.83 APU, respectively. For the successful revascularized fingers (8 of 10 fingers) values from 19 to 223 APU (mean 98.52\u2009\u00b1\u200915.48) were demonstrated. All of the replants survived, but due to venous occlusion two digits required revision 12 and 35 h after revascularization, respectively. In the two cases, Easy\u2010LDI also showed a constant and slow decline of the perfusion values. Furthermore, Pearson normalized correlation coefficient showed a positive significant correlation between temperatures of the replants and LDI\u2010values (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001, <jats:italic>r<\/jats:italic>\u2009=\u2009+0.392) and a negative significant correlation between \u0394temperature and LDI\u2010values (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001, <jats:italic>r<\/jats:italic>\u2009=\u2009\u20130.474).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The LDI\u2010device might be a promising additional monitoring technique in detection of perfusion disturbance in monitoring digital replantations.<\/jats:p><\/jats:sec>","DOI":"10.1002\/micr.30318","type":"journal-article","created":{"date-parts":[[2018,3,15]],"date-time":"2018-03-15T12:08:27Z","timestamp":1521115707000},"page":"627-633","source":"Crossref","is-referenced-by-count":3,"title":["Laser doppler imaging as additional monitoring after digital replanting: A prospective study"],"prefix":"10.1002","volume":"38","author":[{"given":"Marc","family":"Schmid","sequence":"first","affiliation":[{"name":"Department for Plastic, Reconstructive and Hand Surgery, Inselspital Bern University Hospital Bern Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6466-2199","authenticated-orcid":false,"given":"S.
