What happens to the debris created from an orbital atherectomy?

The debris created from an orbital atherectomy is specifically designed to be smaller than 5 micrometers in size. This microscopic size is critical because it allows the debris to pass easily through the circulatory system without causing obstruction or significant downstream effects. The orbital atherectomy technique focuses on removing plaque from the artery while minimizing the risk of complications, such as embolization of larger debris that could lead to ischemic events.

By reducing the size of the debris to be smaller than 5 micrometers, the procedure enables the safe passage of these particles through the bloodstream. This is particularly important in interventional radiology, where patient safety and the prevention of complications are paramount. The design of the procedure aims to ensure that the debris can be flushed away naturally with the blood flow, instead of remaining trapped within the vessel or causing blockages, which is why this particular size is highlighted as being favorable.
