Axillary artery tumor embolism secondary to mitral valve myxosarcoma in a dog

Abstract

To the authors' knowledge, there is no report of myxosarcoma originating on the mitral valve in dogs, although it has been reported in the human literature. To the authors' knowledge, there are also no reports of tumor embolism of the axillary artery in a dog. This case demonstrates a unique presentation of a dog that had a myxosarcoma tumor embolism. It also describes the use of angiography for diagnosis and localization of the vascular obstruction and a variety of interventional techniques for the treatment of thromboembolism.

Diagnostic and therapeutic approach to cardiac myxosarcoma in a dog

“…Myxomas, benign tumors of connective tissue, are slow-growing tumors that cause organ-specific damage such as in the skin, kidney, joints, and heart (1). In dogs, there is little information on diagnostic approaches applied in myxosarcomas arising from the tricuspid valve (TV), despite a few previous histopathological examination reports (2,(4)(5)(6).…”
