Fistula thrombosis

Normally, if we get injured a process of coagulation is activated. The body naturally uses platelets - also called thrombocytes - to form a layer which prevents blood loss.

If this happens internally the process is called thrombosis and means the formation of blood clots inside a blood vessel, which then interferes with the regular flow of blood in the circulatory system. The mechanism of thrombosis can be activated by so-called “haemodynamic mechanisms” such as low blood speed, change in temperature or changes in blood pressure.The fistula arm of a dialysis patient is particularly vulnerable to these phenomena for a number of reasons.

After repeated cannulations the fistula becomes sensitive and delicate. Additionally, when the plasmatic water is removed after each dialysis session, the concentration of blood cells grows, which means that the blood gets thicker. Sometimes the blood pressure drops, so the blood speed slows down.

However, by taking good care of the fistula arm in your daily routine, you can keep the potential thrombosis activation factors down to a minimum!
