Transarterial catheter embolization of a sarcoma for preoperative conditioning.

This paper presents a case of an undifferentiated pleomorphic sarcoma/NOS (not otherwise specified; former pleomorphic - storiform malignant fibrous histiocytoma) of the lower leg, of a huge tumor causing ulceration of the cutaneous surface. To improve preoperative conditions, selective transarterial devascularization of the tumor feeders was performed. At operation the tumor was completely ischaemic allowing for clear tumor demarcation with little blood loss during surgery.
