title: [Reoperative off-pump coronary revascularization via left thoracotomy using the PAS-Port system to the descending thoracic aorta: report of a case].
abstract: We performed redo-off-pump coronary artery bypass grafting( OPCAB) via a left thoracotomy using the PAS-Port system for proximal vein graft anastomoses in a patient with posterolateral myocardial ischemia. The patient was a 76-year-old man who had undergone coronary artery bypass grafting (CABG)[ left internal thoracic artery( LITA)-left anterior descending artery( LAD), saphenous vein graft(SVG)-posterior descending artery( 4PD), and SVG-postero-lateral branch( PL)] 14 years previously. Coronary angiogram showed that the LITA-LAD graft was patent but that the SVG-PL, left main trunk( LMT) and proximal right coronary artery(RCA) were occluded, and that there were 90% stenoses of LAD #7 and SVG-4PD anastomotic site. With catheter intervention therapy, stenosis of the SVG-#4PD was dilated. We then performed revascularization from the descending aorta to the second diagonal (D2) and PL with a saphenous vein graft via left thoracotomy using off-pump technique. To avoid descending aortic clamping, we used the PAS-Port system for proximal anastomosis. The postoperative course was uneventful and the patient was discharged on postoperative day 28. A redo-CABG is thought to be with high risk. Our procedure, however is safe and useful and can be an option for redo-CABG in the posterolateral area.
