How is interventional operation to return a responsibility?

summary

Interventional therapy is a kind of minimally invasive treatment using modern high-tech means, that is, under the guidance of medical imaging equipment, special catheter, guide wire and other precision instruments are introduced into the human body to diagnose and locally treat the diseases in the body.

How is interventional operation to return a responsibility?

First, the application of digital technology in interventional therapy expands the doctor's vision. With the help of catheter and guide wire, the doctor's hands are extended. Its incision (puncture point) is only the size of a grain of rice. Without cutting human tissue, it can treat many diseases that can not be treated in the past and must be treated surgically or in internal medicine, such as tumor, hemangioma, various bleeding, etc. Interventional therapy has the characteristics of no operation, small trauma, quick recovery and good effect. It is the development trend of medicine in the future.

Second, DSA interventional fusion therapy is one of the relatively novel methods for the treatment of femoral head necrosis. It uses the superb arterial cannulation technology, and directly injects drugs into the blood vessels supplying the femoral head to relieve vasodilation and spasm, and dissolve the thrombus obstruction, so as to improve the blood supply of the femoral head, It can provide a good basis for drug absorption.

Third: regardless of any nature of femoral head necrosis, the basic pathology is that the vascular lesions on the surface of the femoral head lead to femoral head necrosis due to poor blood supply. According to the different degrees and causes of femoral head necrosis, experts from the special research group of femoral head necrosis have developed specific drugs for femoral head necrosis. DSA intervention and fusion therapy is based on the principle that drugs are directly injected into the blood supply artery of the femoral head through catheter, so as to maintain the high concentration of local drugs for a long time and make the diseased blood vessels unobstructed and the emergency blood vessels open, In order to increase the blood supply, the collateral circulation is increased, the nutrient vessels of the femoral head are dredged, and the elimination of metabolites is promoted, so that the necrotic bone is gradually absorbed. Drugs also make the new bone form slowly, so that the necrotic bone can be repaired, the pain is relieved, and the symptoms are improved.

matters needing attention

1. The operation has the advantages of small wound, less pain, quick recovery and definite curative effect. 2. The treatment is safe and reliable without any discomfort. 3. DSA intervention was not affected by season, and long-term medication and inconvenience were avoided after operation. 4. The drug dosage is small, the local drug concentration is high and there is no drug resistance.
