    Area of Science:

    • Interventional Radiology
    • Vascular Imaging
    • Pancreatic Diseases

    Background:

    • Pancreatic venography is essential for diagnosing pancreatic conditions.
    • Existing arteriography methods have limitations in visualizing certain pancreatic tumors.

    Purpose of the Study:

    • To assess the feasibility and safety of retrograde pancreatic venography.
    • To evaluate transhepatic portal catheterization for pancreatic venous access.

    Main Methods:

    • Transhepatic portal catheterization was performed in 10 dogs via jugular and hepatic veins.
    • Catheters were used to access individual pancreatic veins for retrograde venography.
    • Contrast injection technique was optimized for detailed visualization.

    Main Results:

    • Detailed visualization of the pancreatic venous system was achieved without apparent injury.
    • Improper catheter wedging led to contrast extravasation and hemorrhagic pancreatitis.
    • The technique demonstrated potential for visualizing the pancreas.

    Conclusions:

    • Retrograde pancreatic venography is a feasible technique for pancreatic venous visualization.
    • Careful technique is essential to prevent complications such as hemorrhagic pancreatitis.
    • This method may offer diagnostic advantages for pancreatic cancer and islet cell tumors when safety is further established.
