Summary
Routine computerized cerebral tomography (CCT) scans in patients with transient ischemic attack (TIA) undergoing carotid endarterectomy (CEA) did not alter management or outcomes. The study questions the routine use and cost-effectiveness of CCT in these patients.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Transient ischemic attack (TIA) is a critical warning sign for stroke.
- Carotid endarterectomy (CEA) is a common procedure to prevent stroke in TIA patients.
- The utility of routine neuroimaging, such as CCT, in guiding CEA management is debated.
Purpose of the Study:
- To evaluate the impact of routine computerized cerebral tomography (CCT) on patient management and outcomes following carotid endarterectomy (CEA) for transient ischemic attack (TIA).
Main Methods:
- Retrospective review of 140 patients with TIA undergoing CEA over 11 years.
- All patients had carotid duplex scanning and CCT prior to CEA.
- Data analyzed included patient demographics, risk factors, CCT findings, and postoperative outcomes.
Main Results:
- CCT revealed abnormalities in 24% of patients (lacunar infarcts, old infarcts, cortical infarcts).
- These CCT findings did not influence the management decisions for CEA.
- The postoperative stroke rate was 2.9%.
Conclusions:
- Routine CCT scanning in TIA patients undergoing CEA does not impact patient management or outcomes.
- The routine use of CCT in this context is not cost-effective and is therefore questioned.
