Summary

Carotid endarterectomy (CEA) can be safely performed without preoperative angiography in select patients. Reliable duplex scans are crucial for identifying suitable candidates and ensuring patient safety.

Area of Science:

  • Vascular Surgery
  • Neurology
  • Diagnostic Imaging

Background:

  • Cerebral angiography carries significant risks.
  • Duplex scanning offers a noninvasive alternative for evaluating extracranial cerebrovascular disease.
  • Carotid endarterectomy (CEA) is a common surgical intervention.

Purpose of the Study:

  • To evaluate the safety and efficacy of performing CEA without preoperative angiography.
  • To determine the outcomes of CEA performed based on clinical assessment and duplex scanning.
  • To identify criteria for selecting patients who can safely forgo preoperative angiography.

Main Methods:

  • Retrospective review of 227 CEAs performed between 1990-1995 without preoperative arteriography.
  • Analysis of patient indications, anesthesia types, and postoperative outcomes.

  • Comparison of duplex scan results with clinical findings.

    • Main Results:

    • Low stroke rate (1.56%) and mortality (1.04%) in patients undergoing CEA without angiography.
    • 91% of procedures were performed under local anesthesia.
    • Discrepancies in duplex evaluation were rare (2 cases).

    Conclusions:

    • CEA can be safely performed without preoperative angiography in patients with clear symptoms, physical findings, and reliable CT and duplex scans.
    • The reliability of the duplex scan laboratory is paramount.
    • Angiography remains indicated for atypical presentations or conflicting diagnostic data.
