A retrospective study of carotid endarterectomy
Insights
This study analyzed 85 carotid endarterectomies, finding a low mortality rate but a 3.6% stroke rate. Delays in surgery after referral were common, especially for non-asymptomatic lesions.
Area of Science:
- Vascular Surgery
- Cerebrovascular Disease
Background:
- Carotid endarterectomy is a surgical procedure to remove plaque from the carotid arteries.
- Assessing the outcomes and patient selection factors for this procedure is crucial for improving patient care.
Purpose of the Study:
- To determine the immediate mortality and morbidity associated with carotid endarterectomy.
- To identify factors influencing patient selection for the procedure.
Main Methods:
- Retrospective review of 85 carotid endarterectomy case histories.
- Categorization of indications, referral sources, and neurological conditions.
Main Results:
- One perioperative death (1.2%) and a 3.6% stroke rate were recorded.
- Over two-thirds of operations for non-asymptomatic lesions were delayed beyond 2 weeks post-referral.
- Half of all operations experienced a delay exceeding 1 month from initial referral.
Conclusions:
- Carotid endarterectomy demonstrated acceptable immediate safety during the study period.
- Significant delays in surgical intervention were observed, particularly for non-asymptomatic cases, warranting further investigation into patient selection and referral pathways.
Abstract:
85 carotid endarterectomies were performed by the vascular unit at the Princess Alexandra Public Hospital between 1 July 1973 and 30 June 1978. The case histories of the patients undergoing the procedure were studied and the immediate mortality and morbidity associated with the procedure during the period were determined. 1 patient died following the procedure and 3.6% of operations resulted in a completed stroke. The indication for the operation, the referral source and the neurological condition of the patient undergoing the procedure were categorised in an attempt to determine the factors governing the selection of patients for this procedure. Excluding asymptomatic lesions, more than two-thirds of the operations were performed later than 2 weeks after the time of first referral to the hospital. Half the operations were performed after a delay of more than 1 month.
