ANEURYSMS AND PSEUDOANEURYSMS OF SAPHENOUS-VEIN CORONARY-ARTERY BYPASS GRAFTS

Aneurysms of saphenous vein grafts to coronary arteries are unusual co mplications of coronary artery bypass graft (CABG) surgery Three patie nts (men aged 47, 62, and 68 years) are presented with spontaneous che st pains 10, 21, and 17 years after CABG surgery. In one case, the sap henous vein graft had eroded into the right atrium and had established a fistula between the graft and the right atrium. Diagnosis of saphen ous vein graft aneurysms was confirmed by echocardiography, computed t omography or magnetic resonance imaging, and by arteriography. Two pat ients were treated surgically, the third by percutaneous coil embolisa tion followed by balloon angioplasty of the right coronary artery.
