Embolization to reverse severe recurrent hepatic encephalopathy.

Five patients with porto-systemic shunts, four spontaneous and one surgically created, presenting severe recurrent hepatic encephalopathy rebel to clinical treatment were angiographically examined. A spontaneous splenic-renal veins shunt was observed in four cases and a mesocaval shunt was identified in the remaining patient. Two thirds embolization of the spleen was able to control hepatic encephalopathy in two patients. Percutaneous transhepatic portography and selective embolization of the shunt was performed in two other patients with good results. Percutaneous transcaval embolization of the mesocaval shunt succeeded to control hepatic encephalopathy in the remaining patient. Splenic embolization is able to control hepatic encephalopathy in patients with splenomegaly and spontaneous porto-systemic shunt. Direct embolization of the shunt is also able to control hepatic encephalopathy as should be expected.

Chronic portosystemic encephalopathy: embolization of portosystemic shunts.

Operative ligation of portosystemic shunts is effective in controlling chronic portosystemic encephalopathy (CPSE) but is associated with significant mortality. Review of the records of five patients with CPSE treated with radiologic occlusion procedures showed that these are suitable alternatives to surgery. Three patients had alcoholic cirrhosis, one had hepatic fibrosis from schistosomiasis, and one had post-necrotic cirrhosis. All had CPSE with progressive, severe cerebral impairment refractory to clinical treatment. Four patients had a spontaneous splenorenal shunt, and one had a surgically created mesocaval shunt (MCS). Partial splenic embolization was performed in two patients, direct shunt embolization was performed via percutaneous transhepatic portography in two other patients, and an MCS embolization was performed in one patient through the inferior vena cava. In four patients embolization controlled the CPSE. In the remaining patient it could not be evaluated because of his premature death from intraabdominal bleeding, a late complication of the procedure. Interventional radiologic procedures are effective in the control of CPSE in selected patients.

[Hepatic hemangiomas. The importance of the image].

In the authors' experience, 0.24% of the patients submitted to liver imaging (ultrasound or computerized tomography) have hemangiomas. These are shown as solid nodular lesions, mostly found by chance. Sometimes they do not appear as typical solid vascular lesions. The authors' experience and the literature are discussed. A clear and concise approach to this benign neoplasm is suggested.
