Acceptable. With skilled operator and suitably selected vessels, the risks are acceptable, especially if avoidance of open vascular surgery is a priority. Look for appropriate formal training and lots of clinical experience.
Dilation of blockage. Using a vascular catheter, not an open surgical procedure, a balloon is used to dilate a blocked artery. This may be followed by placing a stent, a metal alloy support scaffold, can be placed to hold the vessel open. Aggressive medications will be needed to control the risk factors that contributed to the blockage.
