摘要: OBJECTIVE. The purpose of our study was to assess the variation in size acute necrosis and thermal map measured during cryoablation multiple organs using same ablation protocol for each organ.MATERIAL AND METHODS. Eight female pigs underwent one per organ kidney, lung, liver performed with open surgery a 2.4-mm cryoprobe. A 12- 8-minute double-freeze cycle used. Intratissue temperatures were monitored 16-gauge thermometers spaced at 5.0-mm increments from comparison results among tissues analysis variance. -20°C diameter correlated tissue damage. kidneys, lungs, removed examined histologically pathologic complete coagulative zone.RESULT. single cryoprobe had mean ice ball 38.5 ± 4.7, 35.5 3.6, 32.5 2.7 mm, respectively. achieved 24....
