Excellent outcomes with angiographic subsegmentectomy in the treatment of typical hepatocellular carcinoma: a retrospective study of local recurrence and long-term survival rates in 120 patients with hepatocellular carcinoma.

Background: The authors successfully adopted an interesting and effective treatment for hepatocellular carcinoma (HCC) referred to as angiographic subsegmentectomy (AS). This treatment involved simultaneous embolization of the peripheral feeding artery and the portal vein. The result was that almost all of the HCC and peripheral liver parenchyma developed complete anatomic necrosis.
