[Surgical treatment for aortic aneurysms associated with coronary artery disease-selection of bypass conduit].
Graft replacement for arch aneurysms and concomitant coronary artery bypass grafting (CABG) were performed in four consecutive patients over a three-year period between March 1995 and October 1998. The etiology of the aneurysms was atherosclerosis in all the patients. One early death as a result of a cerebellar infarction occurred on the 74th postoperative day. In all cases, respiratory failure frequently occurred after surgery. In a recent case, the internal mammary artery was used as a graft conduit to the left anterior descending artery (LAD). Both artery and vein grafts were anastomosed to coronary arteries during the initial core cooling. Selective cerebral perfusion was carried out during the reconstruction of the transverse aortic arch and its branches. The left subclavian artery was anastomosed first to secure perfusion to the LAD. To achieve sufficient myocardial protection and obtain good postoperative hemodynamics, CABG was simultaneously performed at the time of aortic aneurysm repair in cases complicated with coronary artery disease.
