Simultaneous bilateral carotid endarterectomies
Insights
Bilateral carotid endarterectomy in a single operation is safe for select patients with symptomatic internal carotid artery disease. This approach avoids risks associated with a second anesthetic and surgery, improving patient outcomes.
Area of Science:
- Vascular Surgery
- Neurology
- Anesthesiology
Background:
- Internal carotid artery disease poses a significant risk for stroke.
- Bilateral disease requires careful management strategies.
- Previous approaches often involved staged surgeries, increasing patient risk.
Purpose of the Study:
- To evaluate the safety and feasibility of performing bilateral carotid endarterectomy in a single operative session.
- To determine if a single-stage bilateral procedure is a viable alternative to staged operations.
Main Methods:
- Twelve patients with symptomatic bilateral internal carotid artery lesions underwent simultaneous bilateral carotid endarterectomy.
- Patients were selected based on neurological clearance and comprehensive angiography.
- General anesthesia was employed, with stump pressure measurements guiding collateral flow adequacy.
Main Results:
- The single-stage bilateral carotid endarterectomy was performed without complications in all twelve patients.
- Patients included those up to age 80 with comorbidities like prior myocardial infarction and stroke.
- Stump pressure monitoring proved a reliable predictor of safe outcomes.
Conclusions:
- Simultaneous bilateral carotid endarterectomy is a safe and effective procedure for carefully selected patients.
- This approach eliminates the need for a second anesthetic and operative procedure, reducing associated risks and delays.
- Single-stage bilateral surgery offers a streamlined and potentially safer management option for bilateral internal carotid artery disease.
Abstract:
Twelve patients with bilateral symptomatic lesions of internal carotid arteries have had bilateral carotid endarterectomy at single operations without complications. These were patients up to age 80 who had prior mycardial infarction, stroke with recovery, and hemispheric and nonhemispheric episodes. Neurologist's clearance and three- or four-vessel intracranial-extracranial angiography preceded all operations, which were performed with the patient under general anesthesia. Stump pressure measurements were the principal guideline of adequacy of collateral flow and predictor of safe outcome. The safety of this concept of bilateral operations during one anesthesia can eliminate uncertainties of sequence and timing, obviate delay and indecision, and avoid the hazards of a second anesthetic-operative experience.
