The outcome in 3225 patients with hepatocellular carcinoma (HCC) was studied in groups with equivalent prognosis treated with resection, transcatheter arterial embolization (TAE), and percutaneous transhepatic ethanol injection (PEI). Significant factors for better clinical background included a tumor diameter of < or = 30 mm, tumor number < or = 3 and(More)
OBJECTIVE We assessed the role of dynamic CT in the evaluation of the efficacy of transarterial chemoembolization with iodized oil for hepatocellular carcinoma. MATERIALS AND METHODS We examined 41 hepatocellular carcinoma lesions (mean diameter, 5.0 cm) in 40 patients (mean age, 60.6 years) who underwent transarterial injection of iodized oil alone (n =(More)
In 19 patients with chronic subdural hematoma, coagulation and fibrinolysis in venous blood taken at the time of surgery and in the hematoma contents aspirated from chronic subdural hematoma were studied. Compared with coagulation results for venous blood, the hematoma contents demonstrated marked prolongation of the recalcification time, prothrombin time,(More)
A randomized, controlled clinical trial was conducted to compare the use of epirubicin (EPI) and doxorubicin (DOX) in Lipiodol (Laboratoire Guerbet, Roissy-Charles-de-Gaulle Cedex, France)-transcatheter arterial chemoembolization as a treatment of hepatocellular carcinoma. One hundred ninety-two hospitals participated, and 415 patients were enrolled in the(More)
The recommended treatment for posterior fossa epidural hematoma has been prompt surgical evacuation. We report 2 patients who were treated conservatively. Both patients were younger than 10 years of age and developed subacute symptoms and signs. Serial computed tomography demonstrated complete resolution of the hematomas and no development of hydrocephalus(More)
Our multimodal treatment of hepatocellular carcinoma (HCC) has brought about a significant improvement of the survival rate. It consists of a combination of hepatectomy and transcatheter arterial embolization using lipiodol (L-TAE). In order to facilitate L-TAE, we have developed a special catheter with notches. A group of patients with HCC (124 cases),(More)
An intraoperative ultrasonographically guided introduction of a balloon catheter into labor or smaller branches of the portal vein within the liver parenchyma made it possible to temporarily occlude them and perform regional staining during resection for tumors. The technique minimized blood loss without hilar dissection for vascular control, and the(More)
The authors reviewed 22 cases of intracranial aneurysm of the anterior part of the circle of Willis. All patients presented with the signs and symptoms of subarachnoid hemorrhage (SAH) and were in good neurological condition on admission. In all cases, early operation was performed to obliterate aneurysm. Subarachnoid blood clots were extensively removed(More)
Four cases of the cheiro-oral syndrome are reported, with a review of the clinical symptoms and signs and the neuroradiological methods used to demonstrate the responsible lesion. In each case, angiography, computed tomography (CT) and magnetic resonance imaging (MRI) were performed. The lesion was found in the thalamus in three cases and in the pons in(More)
