Interventional therapy is a mini-invasive therapy that under the guidance of medical image equipment. It mainly has two categories: vascular interventional therapy and non-vascular interventional therapy or diagnosis. With a 1-2 millimeter cut, paracentesis could be performed with the lead of medical image equipment like CT. Then the special tube, transend or other sophisticated apparatus are introduced into human body for diagnosing the conditions or draw some tissues for topical therapy at the same time or any other time. Interventional therapy is applied vastly in tumor diagnosis and treatments because of its advantages like no operation, small wounds, fast recovery and good effect.
In vascular interventional therapy, anti-tumor medicines are injected into different tumors of various parts of body and embolism is done to tumor and its feeding arteries. Drug concentration of regional perfusion is 2-8 times higher than intravenous drip. Embolotherapy is to cut the tumor blood vessels that the tumor dies out of blood supply; it plays an important role in tumor treatments. Embolic agent can take the anti-cancer medicines into tumor that mitigating effect would happen in tumor.
Non-vascular interventional therapy is performed with the guidance of type-B ultrasonic, CT, nuclear Magnetic Resonance and DSA. The therapy is including biopsy, drainage like drainage for liver abscess, stenting such as esophageal stent implantation, orientation like surgical excision for breast lesions performed under the guidance of orientation, etc.
Nutrition and oxygen supplied by blood vessels are the bases for tumor to survive while capillary growing is the foundation for tumor growing. Because there are many blood vessels in a tumor that delaminate the blood vessel can control the tumor growing and diffusing, then starve the tumor to death.
Antiangiogenic therapy combines with TCM and western medicines can control and kill the rumor by stopping the new tumor blood vessels development. It features specific targeting, no drug resistance, small toxicity and side effect since some Chinese Medicinal components can retard the new tumor blood vessels grow.
Ultra selective arterial embolism and chemoembolization starve the tumor to death by blocking feeding artery and nutrition supply of tumor with vascular occlusive agent. Occlusive agent combines chemotherapeutic medicines to stop the blood feeding while topical chemotherapy can be taken without side effect like whole-body chemotherapy.
In order to make sure chemotherapeutic medicine and embolism agent could be injected to tumor lesions, a minimally-invasive intervention doctor should possesses following 3 points: 1. Skilled centesis that can perform puncture exactly in one time. 2. Knows blood anatomical knowledge very well. 3. h3 imageologic foundation. None of these three can be excluded in interventional therapy. Guangzhou Modern Hospital rolls all above points in one to ensure the success of interventional therapy.
