Endovascular refers to a minimally invasive medical procedure that involves accessing the inside of blood vessels to diagnose or treat various conditions. This technique often uses catheters, which are thin tubes inserted through small incisions, allowing doctors to reach areas of the vascular system without major surgery. Common applications of endovascular procedures include treating aneurysms, blockages, and varicose veins. These procedures can be performed in a hospital or outpatient setting, often resulting in shorter recovery times and less pain compared to traditional surgical methods.
