PROTECTION OF CENTRAL AND PERIPHERAL ORGANS IN AORTIC SURGERY

Abstract

The introduction into clinical practice of hypothermic circulatory arrest, both in the non−perfusion version and with an artificial circulation, was the beginning of active use of systemic hypothermia as an effective element of cerebral and visceral protection during combined cardiac surgeries, including in aorta pathology. To evaluate ways of protecting visceral organs and spinal cord, namely the "no perfusion" technique with drainage of cerebrospinal fluid, lateral aortic compression, left−atrial−femoral bypass, deep hypothermia with cardiac arrest, i.e. hypothermic circulatory arest, bypass grafting, artificial blood circulation and moderate hypothermia in surgery for acute aortic syndrome the results of treatment of the patients with acute bundle aortic aortic abdominal localization were analyzed. There was characterized the proposed and implemented in practice original method of protection, consisting in an access to aorta, which is pressed above the aneurysm at the level of bifurcation, and selective perfusion into the mouth of vessels supplying the internal organs with a custodiol solution with a temperature of 3−4°. All the patients with combined occlusion−stenotic lesions of different arterial pools have aortic prostheses with the inclusion of visceral arteries into bloodstream in different variants. The tendency of the more favorable post−surgery period in the patients to whom the implemented methods of protection were applied. Key words: aortic aneurysm, surgical treatment, organ protection.
