Full textPlatelet activation plays a crucial role in the pathogenesis of artherosclerosis. Circulating activated platelets are thought to trigger thrombotic events in patients with instable angina pectoris, myocardial infarction and transient ischaemic attacks as well as after coronary angioplasty and surgery. We studied the effect of peripheral arterial disease (PAD) on activation of circulating thrombocytes and evaluated the influence on platelet activation of intraarterial digital subtraction angiography (DSA) and percutaneous transluminal angioplasty (PTA) in the area of the lower extremities. Our study included sixteen control subjects with PAD, twenty-five healthy control subjects and thirty-six patients, fourteen of whom were undergoing DSA, twelve were undergoing PTA and ten we examined during both interventions. Blood samples were obtained from a peripheral vein or from the arterial and venous catheter introducer before and directly and four ours after the procedures. To characterize platelet activation, the expression of activation-dependent platelet antigens (CD62 and CD63) was measured using flow cytometry. Platelet sensibility was analysed by an additional in-vitro-activation. Four hours after DSA, we observed a decrease in activation and an increase in sensibility of thrombocytes in both arterial and venous circulation (p < 0.02), most likely due the contrast medium (CM). We assume, that the relative decrease of platelet activation is caused by a reduced life-time. The relative number of activated thrombocytes decreased in both arterial and venous circulation (p < 0.02) four hours after PTA. Furthermore, we observed reduced amounts of activated platelets in the arterial circulation (p = 0.021) immediately after PTA, in correlation with increased times of dilatation and larger ballon-catheters (p < 0.03). This could be explained by slight migration or shortened life-time of activated thrombocytes. The amount of CM and heparin did not have a pronounced effect. The influence of both interventions on the platelet features and functions seemed to attenuate in the four postinterventional hours. Our results show that angioplasty in peripheral vessels causes activation and presumably slight migration or reduced life-time of circulating thrombocytes immediately and four hours after PTA. We postulate that this is mainly induced by dilatation. DSA was also found to be associated with platelet activation, sensibilisation and presumptive minor migration or shortened life-time of circulating platelets. More activated and sensitized thrombocytes circulated in patients with PAD (clinical stage II according to Fontaine) with cardiovascular risk-factors compared to healthy control subjects (p = 0.001). This supports our assumption that preactivated platelets are particularly involved in activation, sensitizing and migration processes or affected by a reduced life-time.

Full textINTRODUCTION: Carotid angioplasty with stent (CAS) under cerebral protection is a therapeutic option in patients with carotid stenosis. There is a risk of embolism even with a filter, and changes in cerebral perfusion after treatment are not clearly understood. The purpose of this study was to evaluate changes in diffusion- (DWI) and perfusion- (PWI) weighted magnetic resonance imaging (MRI) sequences correlating them with the technical aspects of CAS, stenosis characteristics and patient demographic data. METHODS: Thirty-six carotid stenosis patients with an mean age of 72.08 years were submitted to MRI exam one day before and up to 72 hours after CAS with filter protection. All patients were asymptomatic after CAS. Areas of restriction on DWI were correlated to demographic aspects, technique of angioplasty as well the presence of previous stroke by MRI. The parameters, CBV - cerebral blood volume; MTT - mean transit time, and TTP- time to peak, are used for PWI analysis. RESULTS: Eighteen of the 36 patients (50.00%) presented new focus (NF) of restriction by DWI after CAS. All new focus were clinically silent. The NF were located in the cerebral area fed by the carotid artery submitted to CAS in 77.19% and smaller than 10mm in 91.53%. NF in cerebral area not irrigated by carotid artery submitted by angioplasty correspond to 22,81 %. The presence of previous ischemic lesion on MRI was the only factor which influenced the appearance of NF (p=0.037). Demographic factors and aspects related to angioplasty technique had no importance on NF genesis. Improvement in PWI timing parameters - TTP (p<0.001) and MTT (p=0.019) were observed in relation to the contralateral territory (normalized data). CONCLUSION: The restriction NF in the DWI after CAS are more common in the ipsilateral territory (77.19%), however there were some NF in the contralateral territory to the CAS (22.81%), possibly associated with diagnostic catheterization. Most of the NF were small in diameter (<10mm in 91.53%). Short-term improvement in PWI were demonstrated by normalized timing parameters (TTP and MTT).
