Hypothesis

The effect of carotid endarterectomy on the patency of the external carotid artery is unknown.

Conclusion

Carotid endarterectomy results in asymptomatic stenosis of the external carotid artery in a small percentage of patients.

Supporting Evidence

  • Carotid endarterectomy was performed on 255 occasions in 236 patients over ten years.
  • Stenosis of the external carotid artery occurred in 5.5% of patients and was totally asymptomatic.
  • The mean follow-up with duplex ultrasound scan was 3 years.

Takeaway

When doctors do surgery to clear blocked arteries in the neck, some patients might have a small blockage in another artery, but it usually doesn't cause any problems.

Methodology

A retrospective study was conducted using data from patients who underwent carotid endarterectomy between 1997 and 2006, with follow-up using duplex ultrasound.

Limitations

The study is retrospective and may not capture all complications or long-term outcomes.

Participant Demographics

The median age of participants was 72 years, with 143 males and 93 females.

Statistical Information

Confidence Interval

95% confidence interval 2.7–3.3 years
