[6 cases of CABG post coronary stent]

In recent years, percutaneous transluminal coronary angioplasty (PTCA) has been actively carried out as a therapeutic method of the ischemic cardiopathies, and Stent therapy has been clinically applied as settlement method of problematical points of the acute occlusion and dissection of the coronary artery by PTCA. We experienced 6 cases necessitated coronary artery bypass graft (CABG) after insertion of Palmaz-Schatz Stent until March 1992. The emergent bypass was carried out in 3 of 6 cases because thrombotic occlusion developed although Stent was inserted in thrombotic occlusion after PTCA, while 2 cases were not life-saved because of the cardiac function was worsened before operation. Other 3 cases were life-saved by expectant treatment even though stenosis developed again after Stent therapy. Stent therapy is a useful method, while severity in cases using CABG and operative complexity are expected by development of new problematical point in the future.
