Infants who have severe anemia and/or thrombocytopenia can be given blood products; for those who have cardiac failure, diuretics and digoxin are often given. To stop further growth and to speed regression of lesions in infants with more significant clinical sequelae, treatment with corticosteroids or interferon-α-2a is administered. To slow the growth of tumors that are rapidly enlarging, chemotherapy and radiation therapy have been used. Surgical resection, partial hepatectomy, and embolization of afferent vessels should be considered for severe cases. Treatment
Treatment is varied and depends on the site and extent of tumor involvement, sites of metastasis, and specific individual factors. Surgical resection, radiotherapy, and chemotherapy have all been used to treat these masses, although studies on survival have yet to be conducted to delineate various treatment regimens. Kaposiform hemangioendothelioma might respond to chemotherapy or antiangiogenic therapies. Recently propanolol and steroids have been shown to be very effective in kaposiform hemangioendothelioma.

In 2019, it was the 203rd most commonly prescribed medication in the United States, with more than 2 million prescriptions. Synthesis

Reaction of piperazine with 2-furoyl chloride followed by catalytic hydrogenation of the furan ring leads to 2. This, when heated in the presence of 2-chloro-6,7-dimethoxyquinazolin-4-amine (1) undergoes direct alkylation to terazosin (3). == References ==
