What is Peripheral Vascular Intervention?
Interventional therapy is an emerging treatment method between surgery and medical treatment, including endovascular interventional and non-vascular interventional therapy. After decades of development, it is now called the three pillar disciplines along with surgery and internal medicine. The concept of interventional therapy refers to the technology of minimally invasive diagnosis and treatment of diseases by percutaneous puncture under the guidance of imaging equipment (angiography machine, fluoroscopy machine, CT, MR, B-ultrasound, etc.), using puncture needles, catheters, bracket etc.
1. What is peripheral vascular intervention?
A major branch of interventional therapy is peripheral vascular intervention, which refers to the technology of diagnosing or treating other blood vessels except intracranial blood vessels and coronary blood vessels through vascular puncture under the guidance of medical imaging equipment, excluding the technology of diagnosing or treating tumor diseases through vascular route.
2. Peripheral vascular disease
Peripheral vascular disease's incidence has increased significantly in recent years, such as arterial stenosis, arteriovenous thrombosis, aneurysm and so on. Occlusive lesions of peripheral arterial stenosis, commonly seen in atherosclerosis, diabetes, Takayasu arteritis, etc., mainly manifested as decreased skin temperature, muscle atrophy, palpable or weakened pulse, intermittent claudication, and in severe cases, distal limb necrosis occurs, and even amputation is required, and in severe cases, life-threatening; venous thrombotic disease can cause blood stasis and swelling in the affected limb, and there is a risk of fatal pulmonary embolism; aneurysmal disease is at any time with the risk of tumor rupture and massive bleeding and death.
Peripheral vascular disease has a high disability rate and a certain fatality rate. Medical treatment has little effect. Surgery is an invasive treatment method with limited effect. In 1964, American physicians D Yuba and ludkil. pioneered the peripheral vascular interventional treatment method without surgery. In 1972, Gnuntzig invented the double-lumen balloon catheter, which made this technology mature.
Since then, laser angioplasty, dynamic angioplasty, intravascular stent, ultrasonic angioplasty, gene therapy and intravascular radiation therapy have been developed successively to prevent postoperative restenosis.
With the continuous improvement of treatment methods, the indications are continuously expanded, and the treatment effect is significantly improved. The equipment will be compounded, biological and medicinal, and the operation will be simplified.
At present, balloon catheters like balloon dilatation catheters, high-pressure balloon catheters, and endovascular stents will still be the main treatment methods. In the future, intravascular radiation therapy and gene therapy may be the focus of development in the prevention of restenosis. Therefore, more and more diseases treated by peripheral vascular treatment can be treated by percutaneous vascular intervention, and its advantages cannot be replaced by drugs and surgical treatment.
