My port mostly worked for round 5 of chemo

Last week I blogged about the catheter connected to my port being retracted. The surgeon didn’t think this would be an issue for receiving my chemo infusion. Yesterday had I round 5 of my chemo infusion and the port worked fine for receiving drugs from the IV, but not for taking blood draws. In this post I will share that story.

The chemo appointment started as it normally does. One of the nurses accessed my port by connecting a needle contraption through my skin into the port. She then proceeded to flush the port, which the surgeon said might actually undo the retraction. The port flushed fine and there didn’t seem to be any resistance. That was good. But then the nurse went to take a blood draw from the port and she was unable to get anything to return. Her and another nurse tried multiple flushes, I think around eight or so. For some of those tries they had me move my neck into different positions to see if that would help. Nothing made a difference. The flush would go through the catheter fine, but no blood would come back when trying to get a blood sample. After speaking to the surgeon over the phone, the nurse said we would get an x-ray to see what was going on with the catheter now.

As a recap this is the picture previously posted to recreate what my x-ray looked about a month and a half ago. In this picture the catheter is correctly going from the port, up to the neck and down through my jugular, and stopping just outside of the heart.

This next picture is how the port looked about a week and a half ago. Looking at this picture is shows the catheter being retracted into a loop. The end of the catheter is also further away from the heart due to the loop.

Finally, here is a recreation of the x-ray from yesterday. The loop is gone, but now the catheter is in a J shape in the jugular.

After viewing the x-ray I received a visit from the surgeon. He believed flushing the port must have caused the end of the catheter to straighten out. But it was not strong enough to completely extend the catheter. Since the catheter is still in the jugular and not in a smaller vein, the surgeon decided it was OK to proceed on to chemo with the catheter as it is. He noted the blood draw would have to be done on my arm. He also did a couple of flushes to ensure there was no resistance. He also verified blood draws were not possible. At the end of his visit he said we would look at this again in a few weeks after round 6 of chemo is done. After that he would be comfortable fixing the catheter, since I will hopefully be done with chemo treatments. My PET scan after the sixth round will decide if I have to go a full eight treatments. But my PET scan after round three looked good, so I hopeful the next PET scan will show no active cancer in my bones. If I have to go a full eight rounds I’ll speak with the surgeon to see what the plan will be then.

After the surgeon left, a tech from the lab came to take my blood. As usual my numbers were looking good. Each round of chemo my blood numbers have looked good and recovered well from the previous round of chemo.

Finally it was time to receive the drugs through my port. The saline bag flowed fine. Then the antibiotics were put through the IV and they ran fine. All of the drugs the nurse put in through the IV flowed fine.

Hopefully the catheter will be fine for round six of chemo, which happens to be scheduled for the day after Christmas. Fluids flowing from the port to the jugular are working good. The only problem right now is that the port cannot be used to do blood draws. Basically my ports catheter is acting as a check valve. Of all the problems one can have with a catheter or port this one isn’t so bad. But it is something that will eventually have to be dealt with. After I’m done with chemo I’ll have two years of rituximab maintenance infusions.

My port catheter has retracted. Huh?

This week I had to visit my surgeon due to a retracted catheter coming from my port. It ended up not being a big deal. But I will have to keep an eye on it in case the surgeon has to do a repair. In this post I will share how I found out about the retracted port and my experience to figure out what the heck that even means.

My current adventure began last week; specifically on Tuesday, November 22, when I went to see the pulmonary doctor. Actually this adventure really started a few months ago I had been referred to a Pulmonologists for my breathing problems (some of which are documented here). I had to wait a few months in order to see the pulmonary specialist. Of course in the meantime a CT scan found my windpipe was being restricted by a lymph node. Additionally, just a few days after my first round of chemo the lymph node pushing on my windpipe had shrunk and allowed me to breathe again (hallelujah!). Even though my breathing was better I decided not to cancel the appointment with the pulmonologist. I still have some breathing problems, sleeping problems, and questions about how my lungs will recover from the cancer that spread into one of them.

The appointment with the pulmonary doctor actually went pretty quick. He looked at what was done so far and wanted to start off with a sleep study (which I’ll do in a about a month or so) and an X-Ray. After those steps are done he will decide what more should be done about my breathing problems. Thinking back I completely forgot to ask him about the effects of the cancer on my lung; oh well, I’ll save that for next time I see him.

Later that afternoon the nurse called me back to let me know the x-ray had come back looking good. Fluid that had been in my lungs in the past was gone. That was good news. All I had to do now in regards to the pulmonary doctor was wait to have my sleep study. It never occurred to me that having an X-Ray would lead to a visit with another doctor.

Late Friday of that week the results of the x-ray were released to my online chart. I don’t actually get to see the scan, but I can view the lab tech notes. Out of curiosity I decided to log on and review these notes. Here is part of what I saw in the impression section:

1. The catheter of the right chest wall port has retracted and the tip now projects in the region of the confluence of the right IJ vein and innominate vein.

Huh? My catheter had retracted? I couldn’t help but wonder what that meant. It sounded potentially bad. The catheter being referred to in the notes goes from the port just under the skin on my chest, up into the jugular in my neck, and down to just outside the heart. It is through that port and catheter that I receive my chemo treatments. I began to worry that a problem with my port would cause a problem with my chemo IV infusions.

I did try calling the oncology office, but it was late and they were already gone for the day. So I set up an appointment to speak with the surgeon who put in the port. There were problems with my port install originally, so I though it would be best to hear from him what was going on. Plus I like the surgeon. He knows how to explain things to people who don’t have a medical degree (something not all doctors are able to do).

On Wednesday of this week I had my appointment with the surgeon. I am glad I chose to speak with him. He was quickly able to reassure me there wasn’t a major problem. To explain the retracted catheter he first showed an x-ray of my chest that had been done about a month and a half ago. Below is my attempt to draw what I saw on this x-ray.

The triangle is the port, which is just under the skin on my chest. Connected to the port is the catheter. It runs under the skin up to the base of my neck, where it enters the jugular and travels to the heart. The surgeon said in this x-ray the port and catheter look exactly like they are supposed to.

Below I have attempted to draw what I saw on the new x-ray.

portretracted

This x-ray shows there is a loop in the catheter between the neck and heart. The formation of this loop means the catheter is no longer right next to heart. Or in medical speak it is apparently “retracted”.

The surgeon noted catheters can retract, but he hadn’t seen one retract this far before. It could have been caused by scar tissue. We also talked about whether my lymph nodes shrinking had caused issues. I had a LOT of lymph nodes in my chest which had grown large and hard due to the cancer. When those lymph nodes shrunk the very topology of my body would have changed. It’s possible we will never figure out exactly why the retraction occurred.

Of course then I asked what had to be done about it. He noted the catheter did not appear to be pinched at all and it should work fine. If needed he can do a simple procedure to straighten out the catheter. Basically that would mean a small incision by the port, where he would stick a wire down the catheter to force it back into its original position. Even though that would be a minor procedure, he really didn’t want to do it while I’m still in chemotherapy. The surgeon also noted that when my port gets flushed during the next round of chemo the catheter may be forced to straighten out. He didn’t think that was likely, but it is possible.

In the short-term the surgeon said we wouldn’t do anything about this retraction. If problems with flow are seen during chemo then he would fix it. But if the chemo IV flows fine he would rather wait and do an x-ray in six months to see how the catheter looks then. In the short-term he said a retraction such as this really isn’t a big deal. However over the long-term, such as ten years, if I am still using the same port he will want it fixed sooner rather than later. He explained that as times goes on the bend in the catheter’s rubber could begin to degrade and cause a leak. It really depends on how long I will keep this port and catheter in. Right now I have one or two months of chemo left, plus two years of maintenance infusions. Hopefully after that this port comes out.

I guess I am back to my rambling ways as this post went longer than planned. In this post I shared my experience of finding out about a retracted catheter. More importantly I shared my experience learning what the heck a retracted port even is. Its times like this I miss the days when I would go years without seeing a doctor.
