[Roentgenomorphological features of coronary artery lesions and coronary shunts in patients with relapse of myocardium ischemia after coronary bypass surgery].

The relapse of ischemia was detected in 127 patients in clinical series after coronary bypass surgery. It was noted in terms from 1 month till 204 months. The basic clinical manifestation or the relapse of ischemia was the recurrence of heart stroke in 74.8%. According to the data of coronary bypass angiography, the main cause of the ischemia relapse appears to be the dysfunction of early formed shunts in 64.6% patients. The development of early thrombosis of autografts is substantially determined by the pool and degree of stenosis of shunt coronary arteries.
