ABSTRACT

About 80% of hepatocellular carcinoma (HCC) patients are in advanced stages and ineligible for curative surgery. Palliative treatments just maintained limited survival, thus an effective downstaging therapy is badly needed. Here we report an initially unresectable patient who underwent radical hepatectomy after successful downstaging with selective internal radiation therapy (SIRT). A 34-year-old man was diagnosed with China Liver Cancer Staging (CNLC) IIIa HCC. Due to insufficient future liver remnant and vascular involvement, the patient was suggested to be unresectable. SIRT with yttrium-90 resin microspheres was given. At three months post-SIRT, a complete response was achieved. The tumor was downstaged to CNLC Ia stage. The patient underwent anatomical hepatectomy 5 months after SIRT. Histopathological examination of the resected specimen showed 4% viable tumor cells inside a necrotic mass. To our knowledge, this is the first case who underwent SIRT with yttrium-90 resin microspheres in China mainland. The success of the downstaging in this case renders a possible cure to be achieved in an initially unresectable patient. In addition, the nearly complete tumor necrosis in the resected specimen indicates a good prognosis post-surgery. This is the first case who underwent SIRT with yttrium-90 resin microspheres in China mainland. SIRT followed by anatomical hepatectomy is a potentially curative strategy for unresectable HCC, which deserves a confirmative trial in the future.

ABSTRACT

Hepatic arterioportal fistulae (APF) are abnormal communications between the hepatic artery and the portal vein. In this report, we present the second case in the literature of a symptomatic APF presenting as a gastric variceal bleeding. A 55-year-old female presented to our facility with hematemesis. Upper endoscopy revealed a bleeding gastric varix. A computed tomography scan identified a large left hepatic lobe APF between the left hepatic artery and the left portal vein. Through angiography coil embolization was performed and with resultant loss of arterial flow, the APF was decompressed. On hospital day 3, the patient developed new melena. Portovenogram was performed and a TIPS stent was deployed. The patient subsequently did well. Hepatic arterioportal fistulae can result in portal hypertension secondary to arterial blood flowing directly into the portal vein bypassing the hepatic sinusoids. Iatrogenic causes (e.g. percutaneous liver biopsy) represent more than 50% of published cases of APFs. Most APFs resolve spontaneously as they are small and peripherally located. In rare instances, when APFs are centrally located, clinical symptoms develop. There have been 30 reported cases of symptomatic intrahepatic APFs following percutaneous liver biopsy. Of those, only one case presented as a gastric variceal bleed. Digital subtraction angiography is the gold standard in the diagnosis and treatment of APFs. In addition to initial embolization, we elected to treat the patient with TIPS due to the magnitude of her bleed. Although rare, intrahepatic APF should be kept on the differential of a patient presenting with isolated gastric varices.
