Decreased recurrent carotid stenosis by routine patching and intraoperative scanning

Area of Science:

• Vascular Surgery
• Diagnostic Imaging
• Cardiovascular Medicine

Background:

• Carotid endarterectomy (CEA) is a procedure to remove plaque from carotid arteries.
• Recurrent stenosis after CEA can lead to stroke.
• Optimizing CEA outcomes requires effective surgical techniques and postoperative monitoring.

Purpose of the Study:

• To evaluate the outcomes of CEA using Dacron patch angioplasty combined with intraoperative color-flow duplex scanning (CFS).
• To assess the incidence of perioperative morbidity and recurrent stenosis in patients undergoing this combined approach.

Main Methods:

• A review of 212 CEAs performed with Dacron patch angioplasty and intraoperative CFS over a 3-year period.
• Exclusion of patients with primary closure, vein patch, or redo endarterectomy.
• Serial CFS follow-up at specific intervals post-surgery to detect stenosis.

Main Results:

• Low perioperative morbidity: 1.4% stroke, 0.94% transient ischemic attacks, 1.4% hypoglossal nerve paresis.
• Intraoperative CFS identified major defects requiring revision in 2.8% of cases.
• A significantly low rate of recurrent stenosis (1.4%) was observed, compared to previous studies.

Conclusions:

• The combination of Dacron patch angioplasty and intraoperative CFS in CEA is associated with low perioperative complications.
• This combined strategy effectively reduces the incidence of recurrent carotid stenosis in the early postoperative period.
