    Summary

    This study on aortoiliac and aortofemoral bypass grafts found a high five-year patency rate of 88%. Additional procedures significantly increased complications and blood transfusions, suggesting careful surgical decision-making.

    Area of Science:

    • Vascular Surgery
    • Graft Patency

    Background:

    • Aortoiliac and aortofemoral bypass grafts are crucial for treating peripheral artery disease.
    • Assessing factors influencing graft patency and patient outcomes is essential for optimizing surgical strategies.

    Purpose of the Study:

    • To evaluate the five-year patency rates of aortoiliac or aortofemoral bypass grafts.
    • To compare outcomes based on graft laterality, inclusion of sympathectomy, and graft type (aortofemoral vs. aortoiliac).
    • To determine the impact of additional procedures on complications and blood transfusion requirements.

    Main Methods:

    • Retrospective review of medical records from 165 patients undergoing aortoiliac or aortofemoral bypass grafting.
    • Analysis of overall five-year patency rates.
    • Comparison of outcomes between different surgical approaches and the necessity of concomitant procedures.

    Main Results:

    • The overall five-year patency rate for bypass grafts was 88%.
    • No significant differences in operative duration, blood transfused, complications, or patency rates were observed between unilateral and bilateral grafts, with or without sympathectomy, or between aortofemoral and aortoiliac grafts.
    • Performing additional procedures alongside bypass grafting led to a significant increase in blood transfused and postoperative complications.

    Conclusions:

    • Surgical intervention for aortoiliac or aortofemoral bypass should be guided by patient symptoms.
    • Anatomical considerations should dictate the choice of anastomosis site.
    • Concomitant procedures should be limited to those with clear therapeutic benefits and essential for ensuring graft patency.
