Eversion endarteriectomy has been proposed as a reliable and rapid method for operating on an ulcerated or stenosed internal carotid artery. The surgical technique is presented in detail. The perioperative course is appraised in a series of 60 operations. Irrespective of age and other diseases in the patients and the preoperative state of the ipsilateral and contralateral vessels, a perioperative morbidity of 1.6% (a temporary neurological deficit) and no lethal outcomes were found. Indication for operation on the carotid artery depends on the spontaneous prognosis based on the vascular morphology and the rate of perioperative complications. The method of surgery described establishes favorable conditions for endarteriectomy even in the asymptomatic stage as well as in exulcerative lesions of the carotid wall.

The influence of controlled ischemia on myocardial ultrastructure was investigated in isolated, metabolically supported canine hearts. Recovery of functionally normal tissue as indicated by the reversibility of morphological alterations was observed up to 60 minutes of anoxia. It was shown that prolonged reperfusion of the empty beating heart supports the recovery of normal cellular ultrastructure. Severe ischemic damage of mitochondria due to ischemia of 60 minutes was almost completely reversible after a reperfusion period of 50 minutes.
