がん患者における深部静脈血栓症の内科的血管内治療

Venous thromboembolism (VTE) remains a significant cause of morbidity and mortality in cancer patients. Although anticoagulation is the mainstay therapy, select patients may benefit from interventional radiology (IR)-guided procedures to address acute, chronic, or refractory thrombotic disease. This article outlines a comprehensive approach to managing cancer-associated VTE using a wide array of IR techniques, including inferior vena cava (IVC) filter placement, catheter-directed thrombolysis, and mechanical thrombectomy for deep venous thrombosis, pulmonary embolism, portal vein thrombosis, and tumor thrombus.
