    Area of Science:

    • Vascular Imaging
    • Interventional Radiology
    • Medical Device Innovation

    Background:

    • Digital angiography is crucial for diagnosing vascular conditions.
    • Traditional venous access methods can be challenging in certain patient populations.
    • Improved catheter design is needed for efficient and effective angiography.

    Purpose of the Study:

    • To describe a modified 5-F dilating catheter for venous injection digital angiography.
    • To evaluate the catheter's ease of placement and image quality.
    • To assess its utility in patients with difficult venous access.

    Main Methods:

    • A 5-F dilating catheter was modified with side holes.
    • The catheter was used for venous injection digital angiography.
    • Placement was attempted in the antecubital vein, often without fluoroscopy.
    • Over 100 carotid artery studies were performed using this method.

    Main Results:

    • The modified catheter was rapidly placed in the antecubital vein in most patients.
    • Successful placement was achieved even in patients with inadequate arm veins.
    • Diagnostic quality images of carotid arteries were regularly obtained.
    • The technique proved effective without routine fluoroscopy.

    Conclusions:

    • The modified 5-F catheter with side holes is an effective tool for venous injection digital angiography.
    • It offers a rapid and reliable method for venous access, particularly in challenging cases.
    • This approach yields high-quality diagnostic images, enhancing diagnostic capabilities.
