ABSTRACT
Objective To investigate the perioperative complications of stenting with symptomatic intracra-nial artery stenosis and study the mechanism and prevention of complications. Methods 63 patients were collect-ed from Stroke Center of Guangxi. They were proved intracranial artery stenosis and performed intracranial stents. Patients′ age,with hypertension,diabetes and hyperlipidemia or not,smoking or not,types and occurrence time of complications were registered. Results 63 patients were registered and 2 patients terminated operation due to blood vessels circuity or serious vessel spasm. Operation success rate reached 96.83％. 5 patients had complications among 63 cases,with complication incidence of 8.20％. 3 patients experienced cerebral hemorrhage and two cere-bral infarction in peri-operation period. 2 patients died of complications and mortality rate was 3.28％. Conclu-sions The incidence rate of complications of intracranial stenting with symptomatic intracranial artery stenosis is relatively high and it can be reduced by preoperative sufficient assessment and prudent selection ,careful operation and strict management after operation.
ABSTRACT
Objective To explore the risk factors of poststroke infection after cerebral infarction. Methods We consecutively included 283 patients with acute ischemic infarcts confirmed by diffusion-weighted imaging (DWI) within 72 hours from Guangxi stroke center. Based on infection status, patients were divided into Not infection group(n=198) and infection group (n=85). The serum cortisol and plasma IL-4 were assessed using chemiluminescent system and double antibody sandwich enzyme linked immunosorbent assay at admission and seventh day later,respectively. Results Compare to no infection group, smoking, mechanical ventilation, diabetes mellitus, dysphagia, COPD,level of consciousness, cortisol and IL-4 at admission, NIHSS, middle area and large area infarction, large atherosclerosis and cardiogenic infarction, left side,both side and subtentorial infarction are more liable to infection(P<0.05);After a Single-factor and Multivariate analysis,we found that cortisol(OR 3.26)and IL-4(OR 2.83)at admission,large area infarction(OR 2.67),left side(OR 3.78)and subtentorial infarction(OR 3.12)were significant correlated with infection, suggesting that they might be the independent risk factors for infection after cerebral infarction. Conclusion Immunological factors and different regional cerebral infarction may increase susceptibility to infection after stroke.
