Abstrakt		Background and purpose: Purpose of study was to estimate incidence, size and localization of spontaneous and iatrogenic brain embolism with MR imaging ( MR ) in 31 patients before and after percutaneous transluminal carotid angioplasty with stenting and distal protection ( PTAF ). Included patients had hemodinamically important carotid stenosis discovered by carotid ultrasound and fulfill criteria for PTAF. We analyze lesions properties on MR before and after PTAF and describe correlations with clinical data and ultrasound properties of stenosis and plaques. Methods: Study was prospective and nonrandomized. Carotid ultrasound was performed as a screening investigation for patients with suspected carotid disease on outpatient basis and before MR and PTAF. During PTAF through transfemoral approach adequate filter device was implanted before stenting, if possible without predilatation of carotid stenosis. First and control brain MR were performed in time window of 24 hours before and after PTAF. Results We examined 31 patients, 14 with known ultrasound result on a side of treated vessels and 17 patients with known ultrasound results on both sides. We discovered 360 brain lesions before PTAF or 11.6 lesions per pat accordingly. 279 (77.5%) were smaller than 1 cm, 81 (22.5%) measure r than 1 cm in diameter. Number of lesions greater than 1 cm was statisti different between groups of asymptomatic and symptomatic patients for both hemispheres (R : p < 0.05, L : p < 0.01). That was not the case if we compared number of all lesions. 94.6% of lesions were found in vascular territory of anterior cerebral artery (ACA) and medial cerebral artery (ACM) without any correlation between them regarding number and largeness of lesions. Lipid plaques were disclosed in 57.0% asymptomatic and 66.6% symptomatic patients. (Abstract truncated at 2000 characters).
