to five percent, whereas reported incidence of severe cases ranges from 0.18 to 1 percent of patients receiving tPA for ischemic CVA. Angiotensin-converting enzyme (ACE) inhibitors and middle cerebral artery distribution have been associated with a higher risk of developing angioedema. The aim of this study is to evaluate the incidence of severe tPA-induced angioedema and its effects on length of stay (LOS) and death.A retrospective chart review of patients receiving tPA for ischemic CVA from January (...) Institutional Incidence of Severe tPA-Induced Angioedema in Ischemic Cerebral Vascular Accidents Tissue plasminogen activator (tPA) is commonly used in ischemic cerebral vascular accidents (CVAs). tPA is generally well tolerated; however, orolingual angioedema is a well-documented adverse effect. Angioedema is generally mild, transient, and unilateral but can manifest as severe, life-threatening upper airway obstruction requiring intubation. Reported incidence for all severities ranges from one

there, it is carefully threaded to the site of arterial narrowing in the neck or elsewhere. Once in proper position, the stent is mechanically expanded so that it can serve as a scaffold to prop open the artery. With carotid angioplasty, transcranial Doppler recordings from the ipsilateral middle cerebral artery found that that blood flow velocity falls transiently during passage of the balloon catheter through the stenosis in the artery or during balloon inflation.

10. Should patients have follow up carotid dopplers to monitor plaque progression if they have had a CVA?

: “ BACKGROUND AND PURPOSE: Patients with symptomatic intracranial atherosclerotic stenosis have a high rate of recurrence. We conducted a prospective study to determine which factors are associated with the progression of symptomatic middle cerebral artery (MCA) stenosis and to evaluate the relationship between progression and clinical recurrence. METHODS: Between January 1996 and February 2000, of a total of 2564 consecutive first-ever transient ischemic attack (TIA) or stroke patients admitted to our (...) risk factors and markers, were independent predictors of recurrent CVD events.” [5] References 1.
