Hemangioma is a common benign tumor in human body, and liver is its favored organ. Usually, most hepatic hemangiomas (CHL) have no obvious clinical symptoms, even if the tumor is huge, but only some non-specific symptoms, such as epigastric discomfort, postprandial fullness, nausea and vomiting, etc., which are often found by patients during consultation or physical examination. For the treatment of CHL, surgical resection was the main treatment in the past, but the recurrence rate after surgery is high, mainly because the tumor is multiple and cannot be excised completely during surgery, or the tumor blood supply cannot be cut off after the establishment of side branches after simple hepatic artery ligation, and for those with multiple huge lesions and located in the hilar region, the surgery is complicated, difficult and easily complicated by fatal hemorrhage. With the rise of interventional medicine, a new pathway has been opened for the treatment of giant CHL, and the interventional treatment of CHL with pinyamycin-iodinated oil emulsion has been clinically applied. The treatment mechanism is: 1. Pingyangmycin has vascular sclerosing effect; 2. it can rapidly inhibit the proliferation of vascular endothelial cells; 3. it destroys the endothelium of blood sinus to make it degenerate, atrophy, degenerate and occlude. Iodized oil has the role of carrier guide, which can carry Pingyangomycin through the catheter to inject into the blood sinus of the tumor area, so that a large amount of local high concentration of drugs, which not only achieve the purpose of embolization of tumor vessels, but also through the slow release of Pingyangomycin can continue to act on CHL endothelial cells, so as to achieve a complete and thorough cure. Therefore, catheter intervention technique is a new method for non-surgical treatment of giant CHL.
