Embolotherapy of liver tumors

Transarterial embolization (TAE) or chemoembolization (TACE) is performed through a microcatheter, using microspheres, drug-loaded particles, or an emulsion of ethiodized oil and chemotherapeutic agents. To preserve as much functional liver tissue as possible, a lobar TACE should be performed in cases of multiple tumors in one lobe, while a single lesion may require a selective or superselective (segmental or supersegmental) approach. Under fluoroscopic guidance all vessels supplying the target tumor are embolized as selectively as possible, until there is disappearance of tumor stain. Complete stasis in the par…
