Embolizations
Portal Vein Embolization
Recently, preoperative percutaneous portal vein embolization has been used to induce
hypertrophy of the future liver remnant before surgery. This technique is currently
used in patients in which a complex extended hepatectomy is anticipated and the
future liver remnant is small or functionally compromised. The recent advent of
helical computed tomography (CT) allows accurate 3 dimensional measurements before
and after portal vein embolization preoperatively.
Chemoembolization
Chemoembolization is the administration of antineoplastic agent together with an
embolizing vehicle. This allows slow release of the agent as well as obstruction
of the blood supply to the neoplasm.
