Last week I had an ultrasound to try and determine the source of the blockage that is causing me to retain fluid in my abdomen, legs and ankles. I was able to see most of the action on the screen.
The kidneys seems to be clear and the lower vena cava (the major vein that runs behind the liver) was also flowing well. They could not see the hepatic vein so when I reported to the hospice with a view to having the fluid in my abdomen drained I had some more tests and these seemed to indicate that perhaps one of the metastases in the liver is applying pressure to that hepatic vein and causing a partial blockage.
They did not drain the abdomen because it is still reasonably soft and some of the swelling is caused by gas. It is a bit risky at this stage so I agreed with their suggestion that as it is not causing major problems, I should wait until it is absolutely necessary before I go down that track. Instead they have increased the diuretic medication and referred me to the physiotherapist at the hospital who specializes in lymphatic drainage. This should at least bring some relief to the swelling to the legs and ankles.
