    Summary
    This summary is machine-generated.

    Intraoperative angiography revealed significant technical defects in vascular reconstructions, including thrombus and anastomotic stricture. Early detection and repair of these issues can reduce the rate of vascular graft occlusion.

    Area of Science:

    • Vascular Surgery
    • Diagnostic Imaging
    • Interventional Radiology

    Background:

    • Vascular reconstructions are critical for restoring blood flow.
    • Intraoperative assessment is essential to ensure the success of vascular procedures.
    • Technical defects can lead to early graft failure and complications.

    Purpose of the Study:

    • To evaluate the utility of intraoperative angiography in identifying technical defects in various vascular reconstructions.
    • To determine the incidence of specific defects and their correlation with vessel size.
    • To emphasize the importance of intraoperative angiography in improving surgical outcomes.

    Main Methods:

    • Intraoperative angiograms were performed on 131 patients undergoing various vascular reconstructions.

  • Patients were categorized into groups based on the type of vascular procedure (e.g., aortoiliac, aortofemoral, femoral artery, miscellaneous, carotid).
  • Abnormalities detected were documented and analyzed.

    • Main Results:

    • Twenty-three patients (17.5%) had abnormalities requiring correction, primarily thrombus (47.8%) and anastomotic stricture (39.1%).
    • Defect incidence varied by procedure group, ranging from 4.3% in aortoiliac to 30% in carotid angiograms.
    • A significant number of technical defects were identified, with incidence related to vessel size.

    Conclusions:

    • Intraoperative angiography is effective in detecting significant technical defects in vascular reconstructions.
    • Addressing these defects intraoperatively can potentially reduce early graft occlusion rates.
    • The findings underscore the value of routine intraoperative angiography in vascular surgery.
