Information for the public
This procedure can only be done as part of a research study. This is because there is not enough evidence to be sure how well it works or how safe it is.
Your healthcare professional should talk to you about the research.
High blood pressure (hypertension) can be caused by overactivity of nerves that help the kidneys (renal) control blood pressure. Sometimes, it does not get better with medicines (resistant). This procedure involves inserting a device through the skin into an artery in the thigh and then into a renal artery. Three small needles are pushed out from inside the device. They go through the artery wall into the fluid-filled space that surrounds it (perivascular). The needles release small amounts of alcohol that destroy the renal nerves (sympathetic denervation). The aim is to lower blood pressure.
