Background
Hemangiomas and vascular malformations are the most common congenital vascular dysplasias with disease rates as high as 2%. The most common hair-growing parts comprise facial parts, four limbs, trunk parts, internal organs, brains and the like, which have adverse effects on the anatomical structure, physiological function and appearance of a human body and bring great mental stress and even psychological disorder to patients. As the lesion progresses, hemangiomas and vascular malformations can lead to complications such as rupture, ulceration, infection, heart failure, and the like. The existing treatment methods are divided into two main categories of surgical open operation and interventional therapy. Because of the advantages of small wound, fast recovery, less complications and the like, interventional therapy is the most promising treatment mode at present, including sclerosing agent injection, laser treatment, spring coil embolization and the like. For aneurysms located in terminal and branch arteries and well-defined vascular malformations of the inflow and/or outflow tract, coil embolization is the most effective treatment. The principle of spring ring embolism is to use metal embolus to mechanically occlude the lumen of the diseased artery and induce secondary thrombosis to completely close the lumen, thereby achieving the purpose of treating hemangioma and vascular malformation.
