Alcohol-mediated perivascular renal sympathetic denervation for resistant hypertension
Closed for comments This consultation ended on at Request commenting lead permission
Description
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 within 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 nerves (sympathetic denervation). The aim is to lower blood pressure.
