Ten re-interventions (43.4%) were performed based on the angiographic defects detected. During the follow-up period, computed tomography angiography of the attached grafts at a mean of 224\u2009days (range, 80\u2013318\u2009days) showed that all repaired grafts were patent. During surgery, the total mean dose of radiation was 1.848\u2009\u00b1\u20090.54\u2009mSv (range, 0.78\u20133.4\u2009mSv) per patient and investigation time was 19.4\u2009\u00b1\u20094.94\u2009minute (range, 9\u201331\u2009minute).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Intra-operative angiography is a powerful tool allowing the identification of graft defects, anastomotic defects and target vessel errors.
