Vertebral arterial reconstruction: a nineteen-year experience.

A M Imparato

    Journal of Vascular Surgery
    |July 1, 1985
    PubMed
    Summary

    Direct vertebral artery operations, though infrequent (5.6%), demonstrated a 71% survival rate and a low stroke incidence (1.5% per year). These procedures addressed severe bilateral blockages or occluded carotid arteries.

    Area of Science:

    • Vascular Surgery
    • Cerebrovascular Disease
    • Neurosurgery

    Background:

    • Vertebral artery operations are less common than carotid artery procedures.
    • Indications for vertebral artery surgery include bilateral flow-restricting lesions or occluded carotid arteries with neurological symptoms.

    Purpose of the Study:

    • To evaluate the outcomes of direct vertebral artery operations.
    • To assess the safety and efficacy of various surgical techniques for vertebral artery disease.

    Main Methods:

    • A retrospective review of 109 direct vertebral artery operations performed between 1964 and 1983.
    • Analysis of surgical procedures including angioplasty, reimplantation, bypass, and decompression.
    • Evaluation of long-term survival and stroke rates.

    Main Results:

    • An overall survival rate of 71% was observed over an average follow-up of 9.9 years.
    • The stroke rate was 1.5% per average year of follow-up.
    • The operative mortality rate was 3%, with common complications including transient phrenic nerve paralysis and Horner's syndrome.

    Conclusions:

    • Direct vertebral artery operations can be performed with acceptable mortality and morbidity.
    • These procedures offer a viable treatment option for specific complex cerebrovascular conditions.
    • Long-term follow-up indicates a favorable survival rate for patients undergoing vertebral artery surgery.
