Summary
Follow-up ultrasound of carotid endarterectomy patients revealed significant rates of recurrent stenosis, particularly in females. This highlights the need for vigilant monitoring after surgical intervention for carotid atherosclerosis.
Area of Science:
- Vascular Surgery
- Neurology
- Diagnostic Imaging
Context:
- Atherosclerosis of the internal carotid artery poses a risk of stroke.
- Carotid endarterectomy is a common surgical intervention to mitigate this risk.
- Long-term surveillance is crucial to assess the durability of surgical outcomes.
Purpose:
- To evaluate the long-term efficacy and safety of carotid endarterectomy.
- To assess the rate of restenosis and occlusion after carotid endarterectomy using Doppler ultrasonography.
- To identify patient demographics and factors associated with adverse outcomes.
Summary:
- This study followed 83 patients (mean age 64) who underwent carotid endarterectomy, with a mean follow-up of 50.6 months.
- Ultrasound revealed 15% of patients with >50% restenosis, requiring reoperation in 8 cases, and 7.6% experienced postoperative occlusions.
- Recurrent stenoses were more common in females and associated with minor symptoms, while acute occlusions led to severe deficits.
Impact:
- Ultrasonography is confirmed as a valuable tool for monitoring patients post-carotid endarterectomy.
- The high incidence of recurrent stenosis raises concerns about the long-term effectiveness of endarterectomy.
- Findings emphasize the importance of regular follow-up to detect and manage post-surgical complications.
