    Real-time ultrasound during arterial reconstruction surgery effectively supplements preoperative arteriography. This diagnostic tool detects vascular defects, including intimal flaps, improving surgical outcomes.

    Area of Science:

    • Vascular Surgery
    • Medical Imaging
    • Diagnostic Technology

    Background:

    • Preoperative arteriography provides essential but sometimes incomplete information for arterial reconstruction.
    • Timely intraoperative assessment is crucial for identifying and correcting vascular defects.
    • Real-time imaging can enhance surgical decision-making and patient safety.

    Purpose of the Study:

    • To evaluate the utility of real-time B-mode ultrasound during arterial reconstruction.
    • To assess its ability to supplement preoperative arteriography.
    • To detect vascular defects immediately after blood flow restoration.

    Main Methods:

    • Real-time B-mode ultrasound scanning was employed during 55 arterial reconstruction surgeries.
    • A total of 100 surgical sites were examined.

    Related Experiment Videos

  • Ultrasound findings were compared with preoperative arteriography and intraoperative events.

    • Main Results:

    • Ultrasound provided new, operation-altering information in 3 instances.
    • Intraoperative scanning detected vascular defects in over 20% of patients.
    • Intimal flaps were the most common defects identified, with one prompting vessel reentry.

    Conclusions:

    • Real-time ultrasound is a sensitive tool for intraoperative vascular assessment.
    • It effectively supplements preoperative arteriography in arterial reconstruction.
    • It aids in the immediate detection of post-reconstruction vascular defects.
