Kasabach-merritt phenomenon: case series and retrospective review of the mayo clinic experience

Abstract

Kasabach-Merritt phenomenon (KMP) is a rare thrombocytopenic consumption coagulopathy associated with an enlarging tufted angioma or kaposiform hemangioendothelioma. We report a case series of patients with KMP and discuss the treatment options and outcomes. Nine patients with a diagnosis of KMP were identified through retrospective chart review-6 had "definite KMP" and 3 had "less likely KMP." The hematologic features of KMP and those of chronic coagulopathy seen with other vascular malformations can be similar, which makes KMP difficult to distinguish.
