Interventional treatment of vascular disease is a method of treating vascular disease through vascular puncture and incision with the help of materials such as guidewires, catheters, stents, and embolic agents under radiological imaging or other imaging surveillance. It differs from traditional open surgical treatment in that it allows treatment of vascular disease at a site far from the lesion. Its advantages are less trauma, less blood loss and faster recovery. 1.Interventional treatment of vasodilatory diseases. Common vascular dilatation diseases such as: abdominal aortic aneurysm, thoracic aortic aneurysm, limb aneurysm and so on. Traditional methods of treating aneurysms require opening the chest, abdomen or cutting the corresponding part of the limb aneurysm, first performing blockage of the upper and lower ends of the vessel, then removing the diseased vessel and replacing it with a section of artificial or autologous vessel of corresponding size. Interventional treatment is completed by simply puncturing or incising the blood vessel at a superficial place in the normal body (most commonly the femoral or brachial artery), entering a guide wire into the location of the aneurysm, and placing a specially designed membrane stent (similar to an artificial vascular conduit) along the guide wire at the site of the aneurysm to connect the upper and lower normal vessels. 2.Interventional treatment for vascular stenosis: Stenosis or occlusion of an artery will lead to ischemia in the blood supply area of the artery and produce a series of symptoms, such as dizziness from carotid stenosis; angina from coronary stenosis; and pain or even necrosis in the limbs from stenosis or occlusion of the lower artery. Interventional treatment involves simply puncturing a normal vessel, passing a very thin guidewire through the stenosis, and then inserting a dilating balloon and inflating it for the purpose of relieving the stenosis. Of course, to prevent retraction of the dilated vessel, a metal support is placed in the dilated area, which is the best thing to do. 3.Interventional treatment of arteriovenous fistula: Normal arteries and veins communicate only through capillaries, and after the arteries supply oxygen and nutrients to the tissues, they flow back from the tiny capillaries. The presence of an abnormal channel between arteries and veins is called an arteriovenous fistula, which returns arterial blood to the heart prematurely and excessively, leading to ischemia and hypoxia in the supplied tissues and also increasing the burden on the heart. For smaller arteriovenous fistulas, the fistula can be quickly eliminated by using interventional methods to insert a spring steel coil, while larger fistulas may be closed by introducing a membrane stent (like a normal water pipe inside a ruptured water pipe), as in the case of dilated arteriopathies. 4.Interventional treatment of congenital vascular malformation. Some congenital vascular malformations grow in special locations, such as intracranial. Surgery is very traumatic, bleeding, and paralyzing or even life-threatening. Interventional treatment can be done by making a 2~3mm puncture from the femoral artery, sending the guidewire and catheter into the deformed vascular area and injecting a spring ring or iodine oil to embolize the vascular malformation, which will have an immediate effect. 5.Interventional treatment of bleeding diseases. Some internal bleeding diseases, such as bronchial dilatation hemoptysis, gastrointestinal hemorrhage, are unusually fierce and life-threatening at any time. Open surgery is difficult to find the bleeding site. By using the interventional method, we can make an angiogram of the internal organs to find out which blood vessel is ruptured and bleeding, and then embolize it, and the treatment effect is very fast. Of course, there are many other vascular diseases that can be cured by interventional treatment. Due to the limitation of space, it is impossible to go into all of them. In conclusion, interventional treatment of vascular disease is widely used, with little trauma, little bleeding, fast recovery and precise results.
