Introduction
Kaposiform hemangioendothelioma (KHE) is a rare vascular tumor. When the
Kasabach-Merritt phenomenon (KMP) is complicated, it can be serious and
requires aggressive treatment. Surgical resection is considered to be
the standard method for the treatment of vascular tumors, but it may be
difficult to perform due to acute bleeding and severe coagulopathy in
patients complicated with KMP. Medical treatments with corticosteroids,
vincristine, and sirolimus have been suggested for the management of
KHE; however, drugs take too long to correct coagulopathy with active
bleeding. Transcatheter arterial embolization may be an alternative
therapy for KHE with KMP.
