Microembolization techniques of vascular occlusion: radiologic, pathologic, and clinical correlation

Vascular occlusion is described using microemboli of a predetermined size for the treatment of neoplastic conditions with a "capillary barrier." Particulated microemboli of either 40--60 micron Gelfoam powder or 200--1,000 micron polyvinyl alcohol foam (PVA) are best. Fluid embolic agents...

Description
Summary:Vascular occlusion is described using microemboli of a predetermined size for the treatment of neoplastic conditions with a "capillary barrier." Particulated microemboli of either 40--60 micron Gelfoam powder or 200--1,000 micron polyvinyl alcohol foam (PVA) are best. Fluid embolic agents such as silicone fluid are used in lesions without a capillary barrier. The radiographic, pathologic, and clinical results in three patients are described in detail. Microembolization is useful in the treatment of neoplastic conditions for it produces tumor necrosis in addition to hemostasis.
