[Endovascular stenting for a recurrent angina patient]

We report successful Palmaz-Schatz stenting for recurrent angina. Coronary arteriography in a 65-year-old man with recurrent angina six months after coronary artery bypass grafting (CABG) showed stenosis in the right coronary artery and in the saphenous vein graft to the left anterior descending artery. For both stenotic lesions, balloon dilatation was performed. However, both lesions recoiled after dilatation. Therefore, Palmaz-Schatz stents were inserted in both stenotic lesions. After stenting, the patient did not experience any further chest pain. Three months later coronary arteriography showed the stents remained patient. Balloon angioplasty for post-CABG angina is technically easier than additional surgery. However, angioplasty by balloon dilatation alone can induce dangerous complications during the acute phase and restenosis frequently develops. This method is not sufficiently effective or safe for recurrent angina. To prevent these problems, the stent was developed as a useful adjunct to balloon dilatation for the native artery. Using this new device, angioplasty for recurrent angina will be safer and more effective than additional surgery.
