Treatment of Hemangiomas by Embolization

摘要: Hemangiomas are high-flow tumors and thus amenable to arterial embolization. However, due the invasive nature of embolization in infants, transcatheter therapy is usually reserved for patients with life-threatening symptoms who failing appropriate medical treatment. Indications include high-output cardiac failure, bleeding, severe coagulopathy kaposiform hemangioendothelioma, control vascularity prior resection. Embolization rapidly involuting congenital hemangiomas typically results rapid improvement volume overload. Improvement sustained because tumor involutes rapidly. Infantile respond initially embolization, but response less dramatic than RICH, recur ongoing proliferation. Infants hemangioendothelioma also increase platelet counts, level drops again a few weeks later.
