From the Guidelines

A normally placed Port-A-Cath can cause venous dissection or rupture due to excessive physical activity, although this is a rare complication. The risk of venous dissection or rupture is higher if the port has been in place for a long time, as the catheter material may become more rigid, or if the patient engages in activities involving extreme arm movements on the side where the port is placed 1. According to the ESPEN guidelines on parenteral nutrition, central venous catheters can be prone to mechanical complications, including damage to the external part of the catheter, which can occur due to inappropriate care of the catheter exit site or chemical damage to the silicone due to inappropriate use of organic solvents 1.

Key Considerations

  • Port-a-caths are designed to withstand normal body movements and moderate physical activity, but extreme movements or repetitive high-impact activities could potentially cause the catheter tip to damage the vessel wall.
  • Activities that might increase risk include weightlifting, contact sports, or repetitive overhead motions.
  • Patients with port-a-caths should generally avoid extreme physical exertion, particularly in the first few weeks after placement when tissue healing is still occurring.
  • If a patient experiences sudden chest pain, shortness of breath, swelling, or unusual sensations around the port site during or after physical activity, they should seek immediate medical attention as these could indicate catheter-related complications including vein damage.

Prevention and Management

  • Appropriate catheter stabilization plays a major role in reducing the incidence of local complications at the exit site and the risk of dislocations 1.
  • Stitches should not be used routinely, and whenever possible, the catheter should be stabilized using a manufactured catheter stabilization device 1.
  • The tip of a central venous catheter should be positioned in the lower third of the superior vena cava, or at the atrio-caval junction, or in the upper portion of the right atrium to prevent tip migration and secondary malposition 1.

From the Research

Venous Dissection or Rupture due to Excessive Physical Activity

There is limited evidence to suggest that a normally placed Port-A-Cath can cause venous dissection or rupture due to excessive physical activity.

  • The studies reviewed focus on complications related to Port-A-Cath placement, such as catheter occlusion, infection, and migration, but do not specifically address the risk of venous dissection or rupture due to physical activity 2, 3, 4, 5, 6.
  • One study mentions the importance of monitoring catheter position and obtaining chest radiographs to screen for possible complications, but does not discuss physical activity as a risk factor 4.
  • Another study describes a case of catheter migration into the ipsilateral jugular vein in a patient with severe cough, suggesting that vigorous changes in intrathoracic pressure may contribute to catheter migration, but does not address the specific issue of physical activity 6.
  • Overall, the available evidence does not provide a clear answer to the question of whether a normally placed Port-A-Cath can cause venous dissection or rupture due to excessive physical activity.

Possible Complications of Port-A-Cath Placement

While the studies do not address the specific question of physical activity, they do highlight other potential complications of Port-A-Cath placement, including:

  • Catheter occlusion and infection 5
  • Catheter migration and fragmentation 3, 6
  • Venous thrombosis and hemothorax 4
  • Pinch-off syndrome and device malfunction 3
