Complications of carotid artery stenting for ischemic cerebral vascular diseases

Objective To analyze the complications and treatment of carotid artery stenting for ische-mic cerebral vaseuladisease. Methods 52 patients with 61 carotid artery stenosis were performed stenting an-gioplasty. 40 Wallstent stents and 20"Z" type stents were implanted successfully. Results All 52 patients were observed sysmetieally during the periproee-dural time. 1 ease was diagnosed definitely hyperperfusion syndrome and 6 eases with temporarily headache or giddy. Carotid sinus reactions were observed during the operation of 12 eases. Transient cerebral isehemia attaeted one ease with botearotid artery serve stenosis during the operation an dcerebral infarction did harm to another ease. 12 eases were provokevaseular spasm. There were 6 eases wit hpuncture hematoma(ineluding 2 pseudoaneurysms)and 1 ease with fistula between the feromal artery and vein. Conclusion The results suggest that the sufficient prepare, standard procedure and correct treatment might sig-nificantly decrease the incidence of CAS complications and improve its prognosis.
