The endovascular approach is a minimally invasive medical technique used to access blood vessels within the body, particularly the brain, through the bloodstream. Instead of traditional open surgery, doctors use catheters inserted through small incisions, usually in the groin or arm, to navigate to the target area. This method is commonly employed to deliver implants, treat aneurysms, or remove blood clots, reducing recovery time and the risk of complications. In the context of neurology, the endovascular approach allows for precise treatment of brain conditions without the need for large surgical openings, offering patients a safer and more efficient alternative.
