    Summary

    Tomodensitometry successfully visualized most aorto-coronary grafts post-surgery. This non-invasive imaging method shows promise for assessing bypass patency and comparing favorably with other techniques.

    Area of Science:

    • Cardiovascular Surgery
    • Medical Imaging

    Context:

    • Assessing the long-term patency of aorto-coronary bypass grafts is crucial for patient outcomes.
    • Traditional methods like angiography can be invasive, necessitating exploration of alternative non-invasive techniques.

    Purpose:

    • To evaluate the efficacy of tomodensitometry in assessing the patency of aorto-coronary grafts.
    • To compare the findings from tomodensitometry with conventional angiography for graft evaluation.

    Summary:

    • Tomodensitometry was used to examine 24 aorto-coronary grafts.
    • 16 of 18 early post-operative grafts were visualized. Four older grafts were occluded, while two older grafts examined more than a year post-surgery were patent.
    • While limited by small sample size for definitive conclusions, tomodensitometry results appeared satisfactory and comparable to other non-invasive methods.

    Impact:

    • Tomodensitometry presents a potentially reliable non-invasive method for monitoring aorto-coronary graft patency.
    • This technique may offer a valuable alternative or adjunct to angiography in cardiovascular graft assessment.
