Interventional medicine is a discipline based on diagnostic imaging and the use of puncture needles, catheters and other interventional devices for the treatment or diagnosis of diseases under the guidance of medical imaging equipment. Compared with the traditional route of drug delivery and surgical methods, it has the characteristics of direct and effective, simple and minimally invasive. Interventional medicine was introduced to China in the early 1980s and has developed rapidly. It is an emerging edge discipline integrating medical imaging and clinical treatment, involving the diagnosis and treatment of many systems such as digestive, respiratory, orthopedic, urological, neurological, and cardiovascular diseases. It has opened up new avenues of treatment for conditions that were previously considered incurable or difficult to treat (various tumors, vascular diseases), and is simple, safe, less invasive, with fewer comorbidities and faster results. Since it is guided by imaging methods, percutaneous puncture and cannulation, drug infusion, vascular embolization or dilation and shaping, it has unique features (minimally invasive, reproducible, accurate positioning, high efficacy, rapid results, low complications, application of multiple technologies, simplicity and ease of use) that traditional medical and surgical sciences do not have, and has rapidly established its importance in the modern medical treatment field. The unique features of the In November 1996, the National Science Committee, the Ministry of Health and the State Administration of Medicine jointly held a seminar on strategic issues of interventional medicine in China, which officially listed interventional therapy as the third major treatment discipline alongside medical and surgical therapies, and called it InterventionalMedicine. The development and popularization of interventional medicine has given patients more opportunities for recovery, and it has become the first choice of treatment for people, which has been paid much attention and welcomed by patients.
Clinical application classification
I. Vascular and non-vascular diagnostic imaging of various parts of the body
1.Angiography: arteriography and venography of various systems.
2.Non-vascular angiography: such as parotid angiography, percutaneous transhepatic percutaneous cholangiography.
2.Interventional treatment of vascular diseases.
1.Intraluminal angioplasty (PTA)/stent (Stent) for the treatment of vascular stenosis or occlusion, such as stenosis or occlusion of blood vessels in various parts of the body caused by atherosclerosis or aortitis, diabetic foot.
2.Thrombolysis/thrombectomy for acute or subacute thrombosis.
3.Application of embolic material, Stent for aneurysm, arteriovenous fistula.
4.Application of puncture + PTA + Stent for treatment of portal hypertension, Buga’s syndrome.
5.Application of embolization or vasoconstrictive drugs to treat bleeding diseases, such as acute and chronic trauma bleeding, gastrointestinal bleeding, hemoptysis, postpartum hemorrhage, etc.
