Insights
Carotid endarterectomy under regional anesthesia is safe for patients with cardiac risk factors. This procedure showed comparable neurological and cardiovascular outcomes across different risk groups, suggesting its viability.
Area of Science:
- Vascular Surgery
- Anesthesiology
- Cardiology
Background:
- Carotid artery disease frequently coexists with cardiac conditions.
- Patients with cardiac risk factors undergoing carotid endarterectomy face increased complication risks.
- Regional anesthesia presents a potential alternative for managing these challenging cases.
Purpose of the Study:
- To evaluate the safety and efficacy of carotid endarterectomy performed under regional anesthesia in patients with cardiovascular risk factors.
- To compare outcomes among patients stratified by cardiovascular risk levels.
Main Methods:
- A retrospective analysis of 129 carotid endarterectomies (± patch plasty) performed between 2006 and 2014.
- Patients received combined cervical plexus block anesthesia.
- Outcomes were compared across high, moderate, and low cardiovascular risk groups.
Main Results:
- The overall rate of cerebrovascular accident was 5.55% (7 patients), with no significant inter-group differences.
- Mortality occurred in 4.76% (6 patients), higher in the high-risk group but not statistically significant.
- Bleeding requiring revision occurred in 3.17% (4 patients); no postoperative surgical infections were reported.
Conclusions:
- Carotid endarterectomy can be safely executed using regional cervical anesthesia across all cardiovascular risk strata.
- Further comparative research between general and regional anesthesia for this procedure is warranted.
Background:
Carotid artery disease is not rare in cardiac patients. Patients with cardiac risk factors and carotid stenosis are prone to neurological and cardiovascular complications. With cardiac risk factors, carotid endarterectomy operation becomes challenging. Regional anesthesia is an alternative option, so we aimed to investigate the operative results of carotid endarterectomy operations under regional anesthesia in patients with cardiac risk factors.
Methods:
We aimed to analyze and compare outcomes of carotid endarterectomy under regional anesthesia with cardiovascular risk groups retrospectively. Between 2006 and 2014, we applied 129 carotid endarterectomy ± patch plasty to 126 patients under combined cervical plexus block anesthesia. Patients were divided into three groups (high, moderate, low) according to their cardiovascular risks. Neurological and cardiovascular events after carotid endarterectomy were compared.
Results:
Cerebrovascular accident was seen in 7 patients (5.55%) but there was no significant difference between groups (P > .05). Mortality rate was 4.76% (n = 6); it was higher in the high risk group and was not statistically significant (P = .180). Four patients required revision for bleeding (3.17%). We did not observe any postoperative surgical infection.
Conclusion:
Carotid endarterectomy can be safely performed with regional cervical anesthesia in all cardiovascular risk groups. Comprehensive studies comparing general anesthesia and regional anesthesia are needed.
