[An unusual indication of deep hypothermia with total circulatory arrest for myocardial revascularization surgery]

The authors relate a case of 69 years old patient with unstable angina and left main coronary artery disease, who underwent aggressive mediastinal radiotherapy for lymphoproliferative syndrome 20 years ago and who needed urgent myocardial revascularization. Due to great calcification and heavily heart adherences it was performed 20 degrees C deep hypothermic circulatory arrest to avoid aortic clamping and to make the anastomosis with better exposition of the aorta and coronary arteries.
