What is interventional therapy? vInterventional therapy is a minimally invasive technique for diagnosing or treating diseases in the body through small puncture points or incisions using specialized interventional instruments such as needles, guide wires and catheters under the guidance of medical imaging (e.g., X-ray fluoroscopy, CT, ultrasound, magnetic resonance imaging) technology. Since its development in the 1970s, more and more patients have been treated with this technology, which has now become one of the third major clinical treatments after medical and surgical treatments. v What diseases are suitable for interventional therapy? v Vascular interventional therapy, refers to transvascular drug infusion and embolization therapy, such as liver cancer and other malignant tumors in various parts of the body and various causes of acute bleeding (such as bronchial hemoptysis, vomiting blood, etc.); hypersplenism, uterine fibroids and hepatic hemangiomas; Bugatti’s Syndrome, cirrhosis, esophagogastric fundal vein embolization, cirrhosis, transjugular intrahepatic portal-caval shunt, arterial thrombolytic surgery; spine, Pelvis and limbs and other orthopedic benign and malignant diseases, nasopharyngeal fibroangioma and other preoperative embolization; peripheral vascular stenosis diseases, such as renal artery stenosis, carotid artery stenosis, vertebral artery stenosis, pulselessness, diabetes mellitus caused by ischemic disease of the lower limbs, angiography of various organs and vena cava filters placement. Non-vascular interventional technology refers to the treatment and diagnostic operation outside the blood vessels, such as percutaneous hepatic puncture choledochotomy (PTCD) or biliary stenting, esophageal stenting, and various benign and malignant tumors, such as argon helium knife, radiofrequency ablation therapy. vWhat are the advantages of interventional therapy? 1.It is minimally invasive. 2, Repeatability. 3, accurate localization. 4, high efficacy, quick effect. 5, low complication rate. 6.The combined application of multiple techniques is simple and easy to perform.
