Pancreatic cancer is one of the common malignant tumors of the digestive system, and its incidence has been on the rise in recent years. The main clinical manifestations are abdominal pain, loss of appetite, emaciation and jaundice, etc. The most common age of onset is 45-65 years old. The pancreatic gland is rich in blood vessels and lymphatic vessels, and there is no envelope, so early metastasis should occur, which can spread directly to the stomach, duodenum, spleen, etc., and to the liver, lung, bone and brain through blood circulation. The treatment of pancreatic cancer is mainly based on surgery, but its early diagnosis is difficult, and most patients are already in the middle and late stages when they are diagnosed, and most of them have metastases to other organs and lymph nodes, so surgery is often unable to remove them radically. As a palliative treatment for pancreatic cancer, interventional therapy has unique advantages in improving patients’ quality of life, improving clinical symptoms and prolonging survival time.
