Five hundred consecutive carotid endarterectomies: emphasis on vein patch closure

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine
• Surgical Outcomes

Background:

• Carotid endarterectomy is a critical procedure for preventing stroke.
• Optimizing surgical techniques, including arteriotomy closure, is essential for improving patient outcomes.
• Vein patch angioplasty is a common method for carotid arteriotomy closure.

Purpose of the Study:

• To evaluate the safety and durability of vein patch closure in carotid endarterectomy.
• To assess short- and long-term complications associated with this technique.
• To analyze outcomes in a large cohort of patients undergoing carotid endarterectomy.

Main Methods:

• Retrospective review of 500 consecutive carotid endarterectomies in 429 patients over 12 years.
• Data collection included patient demographics, surgical indications, procedural details, and postoperative complications.
• Follow-up included serial postoperative duplex scans to assess vessel patency and restenosis.

Main Results:

• The study involved 429 patients (57.1% male, mean age 68 years).
• Vein patch angioplasty was used in 85.8% of cases, with low complication rates (1% death, 0.2% stroke, 1.8% TIA).
• Long-term duplex scans showed no significant residual disease, with rare instances of restenosis (0.7%) and no aneurysms.

Conclusions:

• Vein patch closure is a safe and effective technique for carotid endarterectomy.
• The technique demonstrates low short-term morbidity and excellent long-term durability.
• Contemporary surgical approaches emphasizing distal arteriotomy and patch closure are validated by this experience.
