Algorithm of investigation for choosing repeated surgery on aorta and arteries of the lower extremities

Aim: to estimate the diagnostic capabilities of ultrasound and angiographic methods in evaluation of the vascular bed in patients with occlusion and stenosis of arteries of lower extremities. The results of clinical investigation of 108 patients with relapse of chronic critical ischemia of lower extremities after reconstructive operations were analyzed. All patients were clinically and laboratory examined, the condition of the arterial system investigated by continuous wave Doppler (CW Doppler), color duplex scanning, X-ray angiography, magnetic resonance angiography, computed tomography, three-dimensional computed tomography in three-dimensional reconstruction. In 44 patients, an objective cause of thrombosis in re-development areas and relapse of chronic critical ischemia of lower limbs was detected. Based on the survey re Reconstructive surgery for each patient was elaborated. The optimal methods of preoperative diagnosis of complex lesions in lower limb arteries are Dopplerography, duplex scanning of main arteries, arteries of the foot, toes and angiography
