What is Cathflo used for with a port?
Cathflo is the brand name for alteplase (tPA), a clot-busting medicine. With implanted ports (and other central venous catheters), it’s used when the line becomes blocked by a clot, making it hard or impossible to draw blood or infuse through the port. Alteplase works by breaking down fibrin in the clot so blood flow can return.
How do you know your port needs Cathflo?
Clinicians typically consider a thrombolytic (like Cathflo) when there are clear signs of catheter occlusion, such as:
- The port won’t give a blood return
- Fluids or medication won’t infuse properly (or flow is very sluggish)
Cathflo is used as a treatment for a suspected or confirmed occlusion from a clot rather than a routine maintenance step.
How is Cathflo given to a blocked port?
Cathflo is instilled directly into the catheter/port lumen (not given by mouth or as a typical IV infusion). The medication stays in the line for a dwell time so it can dissolve the clot, then the line is tested again for blood return and adequate flow.
How long does Cathflo take to work?
The goal is to restore patency after the dwell period and subsequent flushing/aspiration attempts. Exact timing depends on the protocol used by the treating facility and the circumstances of the occlusion, but it’s generally managed on a same-visit basis for an access problem.
Are there risks or side effects when using Cathflo in a port?
Because alteplase can affect blood clotting, the main risks are bleeding and bruising at the port site or elsewhere. Patients with certain bleeding risks or recent major bleeding may need extra caution or an alternative plan. Clinicians also watch for allergic reactions and monitor catheter function after treatment.
What if Cathflo doesn’t restore flow?
If the port still won’t work after thrombolytic treatment, next steps can include:
- Confirming the line is positioned and not mechanically obstructed
- Trying an alternative occlusion-management approach per the care team
- Considering catheter intervention or replacement if the problem isn’t clot-related
How much does Cathflo cost (and is there a cheaper alternative)?
Prices can vary widely by dose and setting.
