The cost of interventional procedures consists of three main components: i. The cost of treatment, i.e., the cost of the procedure. The cost of the procedure is usually around 2,000-4,000 yuan, which varies from region to region. Second, the cost of consumables. That is, the materials used in the surgery, including catheter guide wire, etc.. Usually, the catheter guidewire of the .35 system we use is relatively inexpensive, about 1000 yuan is enough. If you need to use a microcatheter for some more delicate operations, the cost may increase by another 3,000-10,000 RMB. If the embolization material uses more expensive materials such as drug-laden microspheres, the cost may be increased by another 20,000 yuan or so, and these need to be determined according to the specific surgical plan. Third, the cost of drugs. In the treatment of liver cancer, the cost of chemotherapy drugs used is about 1500-2000 RMB. Taking liver cancer as an example, the cost of our whole surgery adds up to about$5,000-10,000. If the more expensive materials such as drug-laden microspheres are used, the cost will add another$20,000 or so. Since interventional surgery is a minimally invasive procedure performed under local anesthesia and does not require general anesthesia, there is no big item of anesthesia cost. These are the general information about the cost of interventional procedures.
