Summary
Performing carotid endarterectomy (CEA) within 1 to 4 weeks after stroke shows similar safety outcomes to delayed procedures. This early intervention for symptomatic carotid stenosis is safe and effective, reducing stroke progression risks.
Area of Science:
- Vascular Surgery
- Neurology
- Stroke Medicine
Background:
- Delayed carotid endarterectomy (CEA) after acute stroke is common due to concerns about stroke progression.
- This delay can lead to significant interval stroke rates between 9% and 15%.
Purpose of the Study:
- To evaluate the safety and efficacy of performing CEA within 1 to 4 weeks after an acute stroke.
- To compare outcomes of early CEA with traditional delayed procedures.
Main Methods:
- Retrospective analysis of 228 patients undergoing CEA between 1980 and 2001.
- Patients were grouped by CEA timing: within the first, second, third, or fourth week post-stroke.
- Statistical analysis included chi-squared tests, logistic regression, and ANOVA.
Main Results:
- Perioperative permanent neurologic deficits occurred in 2.6% to 3.4% of patients across all early surgical intervals.
- No correlation was found between infarct location/size and surgical timing.
- Preoperative infarct size was the only factor correlating with postoperative neurologic deficit (P <.05).
Conclusions:
- Early CEA (within 1 month) after stroke demonstrates similar postoperative stroke exacerbation rates across all intervals.
- The incidence of adverse events is within acceptable limits for treating symptomatic carotid stenosis.
- CEA can be safely performed within 1 month of stroke without compromising patient outcomes.
