    Summary

    Vascular endoscopy offers a quick and effective way to check carotid endarterectomy results during surgery. This technique identified issues in 71% of cases, improving patient safety and surgical outcomes.

    Area of Science:

    • Vascular Surgery
    • Medical Instrumentation
    • Diagnostic Techniques

    Background:

    • Carotid endarterectomy is a common procedure to prevent stroke.
    • Intraoperative evaluation is crucial for ensuring successful outcomes.
    • Optical instrumentation advances enable new diagnostic methods.

    Purpose of the Study:

    • To evaluate the efficacy and practicality of vascular endoscopy for intraoperative assessment of carotid endarterectomy.
    • To determine the diagnostic yield of vascular endoscopy in identifying potential complications.
    • To assess the time efficiency of the procedure.

    Main Methods:

    • A prospective study involving 35 carotid endarterectomies.
    • Utilized the Hopkins Optical System for vascular endoscopy.
    • Examined the external and internal carotid arteries post-procedure.

    Main Results:

    • Vascular endoscopy identified positive findings in 71% of external carotid endarterectomies (intimal flaps/shreds).
    • Intimal shreds capable of embolization were found in 6% of internal carotid artery examinations.
    • The procedure took less than 10 minutes in all cases.

    Conclusions:

    • Vascular endoscopy provides a precise and complete intraoperative evaluation of carotid endarterectomy.
    • The technique is practical and efficient, aiding in the detection of potentially embolic material.
    • This method can enhance surgical confidence and potentially reduce postoperative neurologic deficits.
