Recently, a patient with squamous cell carcinoma of the left tongue who was hospitalized in our oncology radiotherapy ward had recurrent oral bleeding, which was once improved and stabilized after treatment with hemostasis and local compression. After understanding the condition, Dr. Yu judged that the bleeding was most likely caused by tumor damage to the artery, and immediately decided to perform external carotid arteriography and arterial embolization with Dr. Yankang Pan, the attending physician. The left external carotid artery angiogram immediately confirmed the judgment of Director Yu, the left lingual artery ruptured and bled like a fountain, the bleeding quickly flowed into the oral cavity, now time is life, immediately block the bleeding artery with embolic agent, and the bleeding stopped immediately with another angiogram, “immediate effect”. “After that, Director Chen A-Xin of radiotherapy ward and attending physician Peng Lu-Xing, the supervising physician, designed a precise radiotherapy plan for the patient’s condition again, and the interventional technique applied to tongue cancer bleeding not only saved the patient’s life by stopping the bleeding through embolization, but also reduced tumor nutrients through tumor The interventional technique applied to tongue cancer bleeding not only saved the patient’s life through embolization, but also reduced the tumor nutrient supply through tumor supply artery embolization to achieve the effect of tumor treatment. Interventional arteriography and arterial embolization can achieve very good efficacy in treating ruptured arterial bleeding in various parts, such as bleeding caused by gastrointestinal tract, respiratory tract, urinary tract, biliary tract, trauma, postpartum and tumor invasion of blood vessels in various parts. Radiation therapy is an important means of tumor treatment to kill tumor cells through radiation, and about 70% of tumor patients need radiation therapy during treatment. The improvement of radiotherapy technology and the clinical application of image guided precise radiotherapy (IGRT), together with the escort of interventional therapy, will greatly improve the effect of tumor treatment in the district hospital.
