[Coronary endarterectomy associated with coronary artery bypass in severe coronary artery disease. 50 cases]. / L'endartériectomie coronaire associée au pontage dans les lésions coronariennes sévères. A propos de 50 observations.

The surgical indications of coronary endarterectomy were defined from a study of 50 cases in which endarterectomy was associated with aorto-coronary bypass surgery. This total represented 6 p. 100 of all the aorto-coronary bypass operations performed in the same period. Coronary endarterectomy was performed "on principal" for the right coronary artery, and "of necessity" for the left anterior descending artery. The special techniques of endarterectomy on the left anterior descending artery are described. Endarterectomy does not increase the operative risk and enables revascularisation of vessels unsuitable for bypass surgery. 85 p. 100 patients are asymptomatic with an average follow up period of 2 years after endarterectomy and aorto-coronary bypass graft of the right coronary artery.
