Knotted ventriculoatrial catheter. Case report

D F Dean

    Journal of Neurosurgery
    |March 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    A knotted infant feeding tube and atrial catheter in a patient were successfully removed. The complex knotting required surgical intervention, but both devices were ultimately retrieved and repositioned.

    Area of Science:

    • Vascular surgery
    • Medical device complications
    • Interventional radiology

    Background:

    • Central venous catheters and feeding tubes are common in clinical practice.
    • Complications such as device malposition and knotting can occur.
    • Management of these complications requires careful consideration.

    Observation:

    • A No. 5 French infant feeding tube became knotted with an atrial catheter.
    • The knotting occurred between the superior vena cava and the left common facial vein.
    • The atrial catheter stretched, allowing knot excision via an antecubital incision.

    Findings:

    • Surgical intervention successfully resolved the knotting complication.
    • A shuntgram confirmed the ventriculoatrial catheter's position in the axillary vein post-excision.

  • The catheter later repositioned itself into the atrial position.

    • Implications:

    • This case highlights the potential for complex knotting between different types of venous access devices.
    • Successful management involved a combination of surgical technique and radiological imaging.
    • Awareness of such rare complications is crucial for preventing patient harm.
