    Summary

    Adding side holes to Teflon catheters for translumbar aortography improves contrast flow and visualization of major vessels. This technique enhances diagnostic imaging of the aorta and brachiocephalic arteries.

    Area of Science:

    • Vascular imaging
    • Interventional radiology

    Background:

    • Translumbar aortography is a key diagnostic tool.
    • Standard catheters may have limitations in contrast delivery.

    Purpose of the Study:

    • To evaluate the impact of side holes on catheter performance.
    • To improve visualization of the aorta and its branches.

    Main Methods:

    • Modification of Teflon catheters with added side holes.
    • Performance assessment during translumbar aortography procedures.

    Main Results:

    • Enhanced flow of contrast material observed.
    • Improved visualization of the aorta and brachiocephalic vessels achieved.

    Conclusions:

    • Side-holed catheters offer superior contrast delivery.
    • This modification enhances diagnostic accuracy in aortography.
