Endovascular surgery is a form of minimally invasive surgery that was designed to access many regions of the body via major blood vessels. Endovascular techniques were originally pioneered for diagnostic purposes by radiologists. Basic techniques involve the introduction of a catheter percutaneously into a large blood vessel. Typically the blood vessel chosen is the femoral artery or a vein found near the groin. Access to the femoral artery for example, is required for coronary, carotid, and cerebral angiographic procedures. The catheter is injected with a radio-opaque dye that can be seen on live X-ray or fluoroscopy. As the dye courses through the blood vessels, characteristic images are seen by experienced viewers and can assist in the diagnosis of diseases such as atherosclerosis, vascular trauma, or aneurysms. In recent years, however, the development of intravascular balloons, stents and coils have allowed for new therapies as alternatives to traditional surgeries such as Coronary artery bypass surgery, carotid endarterectomy and aneurysm clipping.
