Transarterial embolization therapy plays a significant role in tumor treatment, blocking the blood supply to tumor cells without affecting body tissues, causing tumors to naturally necrose due to nutrient deprivation, essentially "starving" tumor cells.
Characteristics of Arterial Embolization
Transcatheter arterial embolization (TAE) is a method of injecting embolic agents through a catheter into the target arteries supplying the tumor, causing arterial occlusion to achieve therapeutic goals. TAE is applicable for palliative and relatively curative treatment of liver cancer, renal cancer, pancreatic cancer, lung cancer, pelvic malignancies, and curative treatment of hepatic hemangioma. TAE is commonly used for embolic hemostasis and pre-operative embolization during major hemorrhage from liver, nasopharyngeal, lung, renal, gastrointestinal, and pelvic tumors, and can also be used for protective embolization to alter blood flow distribution. In tumor treatment, chemotherapy drugs and embolic agents are often combined for embolization, called transarterial arterial chemoembolization (TACE).
Advantages of Transarterial Embolization
A catheter is inserted into the femoral artery and advanced retrograde into the feeding artery, contrast agent is injected for angiography, to determine tumor location, size, number, and vascular distribution; then the catheter is inserted into the tumor-feeding artery to directly inject chemotherapy drugs or embolic agents, eliminating the tumor while blocking its blood supply, causing tumor ischemic necrosis and atrophy.
Transarterial embolization is a minimally invasive tumor treatment technology requiring no surgery, with less toxicity than systemic chemotherapy, increasing local drug concentration and prolonging drug-tumor tissue contact time. 是tumor patientsa commonly usedminimally invasive interventional treatmentmethod, andTreatment Outcomeseffective, can beeffectiveimprovetumor patientsquality of life。
