Stenosis following carotid endarterectomy
The Journal of Cardiovascular Surgery
|May 1, 1985
Summary
Restenosis after carotid endarterectomy for atherosclerosis occurs in 12.5% of cases. Symptomatic restenosis is rare (1%), questioning the procedure
Area of Science:
- Vascular Surgery
- Neurology
- Cardiology
Background:
- Carotid endarterectomy is a standard treatment for carotid bifurcation atherosclerosis.
- The incidence of restenosis following this procedure is not well-established.
Purpose of the Study:
- To determine the incidence of restenosis after carotid endarterectomy.
- To evaluate the clinical significance of post-operative stenosis.
Main Methods:
- Prospective study of 80 carotid endarterectomies in 73 patients over four years.
- Post-operative assessment using Doppler ultrasound with spectral analysis.
- Digital venous angiography used when indicated.
Main Results:
- A 12.5% incidence of post-operative stenosis was observed.
- Symptomatic restenosis occurred in only 1% of patients.
- A significant proportion of stenosis cases were asymptomatic.
Conclusions:
- Carotid endarterectomy has a notable incidence of restenosis.
- The low rate of symptomatic restenosis challenges its routine use for asymptomatic carotid stenosis.
- Further evaluation is needed for asymptomatic cases.
