Summary

Carotid artery thrombosis is a common cause of stroke after carotid endarterectomy. Early detection with OPG/Gee and prompt exploration improve patient outcomes.

Area of Science:

  • Vascular Surgery
  • Neurology
  • Diagnostic Imaging

Background:

  • Management of acute carotid artery thrombosis post-endarterectomy remains controversial.
  • This study retrospectively analyzes stroke etiology and management strategies following carotid endarterectomy.

Purpose of the Study:

  • To review the causes of stroke after carotid endarterectomy.
  • To analyze the effectiveness of different management options for post-endarterectomy stroke.
  • To evaluate the diagnostic accuracy of Oculopneumoplethysmography (OPG/Gee) in detecting carotid thrombosis.

Main Methods:

  • Retrospective review of patients experiencing stroke post-carotid endarterectomy.
  • Diagnosis utilized Oculopneumoplethysmography (OPG/Gee), duplex ultrasound, CT scanning, and carotid exploration.

  • Management strategies included selective exploration, mandatory exploration, and medical treatment.

    • Main Results:

    • Carotid thrombosis was identified as the cause of stroke in 59% of patients.
    • OPG/Gee demonstrated 95% accuracy in detecting postoperative thrombosis (100% sensitivity, 89% specificity).
    • Thrombectomy and patch angioplasty improved neurological status in 7/12 patients, especially when performed within two hours of stroke onset.

    Conclusions:

    • Carotid artery thrombosis is the primary cause of stroke following carotid endarterectomy.
    • OPG/Gee is a reliable diagnostic tool for identifying carotid thrombosis.
    • Prompt carotid exploration and thrombectomy for Grade I or II strokes significantly improve recovery.
