[Modified revascularizing osteotrepanation]

Revascularizing osteotrepanation (ROT) was performed in 44 patients with chronic obliterating diseases of the lower extremity arteries. The modified technique consisted in putting opertures through and through both cortical plates but in the metaphyseal zones of the tibial bone, the muscles were not damaged, fascia was not sutured. A comparison was made of the data of local skin electrothermometry, index of regional systolic pressure (IRSP) on the femur, malleolus-humeral index (MHI) and the distance of painless walking before operation and on the 10th day. After using the modified ROT as compared with the classical one more pronounced rise of local skin temperature of the lower extremity was obtained. The increase of ASI after modified ROT in the II, III and IVth stages of ischemia was 0.26; 0.23 and 0.1 which was considerably higher than after the classical technique of operation. Postoperative increase of IRSP after using the modified technique of ROT was statistically reliable but at the II-III stages of ischemia. Growth of the distance of painless walking achieved 271% that was considerably higher than after the classical technique (172%).
