Abstract
Objectives:
To report the technical success and clinical outcomes of catheterβbased therapy (CBT) for acute ischemic stroke in patients ineligible for intravenous thrombolysis.
Background:
Acute ischemic stroke is common but undertreated. CBT for acute ischemic stroke is a therapeutic option in selected patients who are not candidates for intravenous thrombolysis.
Methods:
Consecutive stroke patients who were ineligible for intravenous thrombolysis and underwent CBT were identified by retrospective chart review. Demographic information, National Institutes of Health Stroke Scale (NIHSS), procedural characteristics, and clinical outcomes during hospitalization and at 90 days follow up were collected. Experienced interventional cardiologists with the consultative support of stroke neurologists were on call for acute strokes.
Results:
A total of 33 acute ischemic stroke patients underwent emergency cerebral angiography, with 26 patients undergoing CBT. Successful βculpritβ artery recanalization was achieved in 23 (88%) of the 26 patients. Inβhospital adverse events occurred in 4 (15%) patients, with intracerebral hemorrhage (ICH) (12%) representing the most common adverse event. The baseline NIHSS for patients who underwent intervention was 16.5 Β± 9.9 (median 16) and improved significantly to 9.9 Β± 8.7 (median 9) (P < 0.001) at hospital discharge. A modified Rankin score of two or less (indicating mild disability) was achieved in half (n = 13) of the CBT treated patients. All cause mortality at 90 days was 8% (2/26).
Conclusions:
In selected patients, CBT provided by qualified interventional cardiologists supported by stroke neurologists, offers a safe and effective option for patients with acute stroke who are not eligible for intravenous thrombolysis. Β© 2008 WileyβLiss, Inc.
