What Is Interventional Therapy

Interventional therapy refers to the use of percutaneous puncture and catheter technology under the guidance of medical imaging or endoscopy, through drug, physical, chemical and other means to directly eliminate or alleviate local lesions, so as to achieve the purpose of treatment.

Interventional therapy has the characteristics of minimally invasive, strong plasticity and accurate localization. For some diseases, its curative effect is better than traditional internal and surgical treatment.

Treatment techniques mainly include:

1 Vascular interventional techniques such as:

① Transcatheter vascular embolization;

(2) Transcatheter local drug perfusion;

③ Transcatheter transluminal angioplasty;

④ Percutaneous endovascular stent placement;

(5) Transjugular portotransluminal shunt;

⑥ Percutaneous removal of vascular foreign body and thrombus;

⑦ Percutaneous intravascular catheter box system implantation;

⑧ Heart valve plasty;

⑨ Radiofrequency ablation;

⑩ Selective angiography and drug-induced angiography.

2. Non-vascular interventional techniques such as:

① Percutaneous needle aspiration biopsy;

② Percutaneous puncture internal and external drainage;

③ Percutaneous discectomy;

④ fallopian tube recanalization;

(5) Ascites and venous bypass;

Hydrocephalus peritoneal cavity or venous bypass;

⑦ internal stent placement;

⑧ Percutaneous gastrostomy;

⑨ stone treatment technology;

⑩ T-tube replacement.

3 Endoscopic interventional techniques such as:

① Transgastroscopic intravenous treatment of esophageal varices;

② Transgastroscopic esophageal cancer stenting;

(3) Endoscopic resection of skull base tumors;

(4) Percutaneous nephrolithotripsy;

(5) Microendoscopic treatment of lumbar disc prolapse, etc.
