POST EMBOLISATION REDUCTION IN VASCULARITY

Endovascular techniques or direct puncture techniques are used to reduce the blood supply of certain tumours to reduce or eliminate intraoperative blood loss during the resection of highly vascular tumours. These are commonly done for hypervascular tumours of the head and neck like juvenile nasopharyngeal angiofibroma, glomus tumours, vertebral body hemangiomas and renal tumours like angiomyolipoma and renal cell carcinoma.
