Visceral angiography and embolization.

Abstract

New aspects of both diagnostic and therapeutic angiography are reviewed in the context of tumor therapy, trauma, and portal hypertension. The use of intra-arterial administration of calcium gluconate as a diagnostic challenge for insulinomas, tumor embolization, and chemoembolization are reviewed. The use of angiography for proximity injuries and the therapeutic aspects of embolization in blunt hepatic, pelvic, and splenic trauma are also noted. Angiography in portal hypertension is emphasized as an adjunct to surgery. The use of the transjugular intrahepatic portosystemic shunt is reviewed and is noted to be of great promise.
