title: [The usefulness of intra-operative angiography during off-pump CABG].
abstract: BACKGROUND
  Recently OPCAB has become more and more common in CABG, although one problem of OPCAB like the quality of anastomosis has not been solved yet. We discussed the usefulness of intra-operative angiography during OPCAB.
  
  
  METHODS
  During March 1997-July 2000, 55 patients underwent OPCAB (including 35 MIDCAB cases) in our institute. Graft flow and anastomosis were examined by intra-operative or immediate post-operative angiography.
  
  
  RESULTS
  Immediate postoperative angiography was performed in 22 MIDCAB cases. In 15 cases an excellent graft flow without stenosis could be confirmed, in 7 cases the native LAD was so small, which caused a poor flow of the LITA and three cases needed additional PTCA because of anastomosis stenosis. Intra-operative angiography was done in 9 MIDCAB and 17 OPCAB. As a result, re-anastomosis was performed in one case of MIDCAB because of severe anastomosis stenosis, one case of OPCAB had confirmed poor flow because of a small LAD, but in 24 cases an excellent graft flow could be seen on time. In 2 cases OPCAB was combined with PTCA to achieve complete revascularization.
  
  
  CONCLUSIONS
  Intra-operative angiography is a useful strategy to confirm the surgical results quickly in OPCAB (included MIDCAB). Using such a strategy, combination of OPCAB and PTCA as a new approach for complete revascularization can be performed safe and smooth.
