Chronic cerebrospinal venous insufficiency in Ménière disease.

Objectives: The aim of this study was to focus on patients suffering from cochleo-vestibular disorder with and without Ménière disease (MD) in order to verify whether chronic cerebrospinal drainage abnormalities could play a role in the etiopathogenesis of endolymphatic hydrops.

Methods: Fifty-two volunteers were enrolled and subdivided into two groups: 24 definite MD and 28 not-MD. Both magnetic resonance venography imaging with contrast-enhanced imaging of the venous cerebrospinal system (MRV) and venous echo-color Doppler (ECD) were performed.

Small nodular hepatocellular carcinoma treated by laser thermal ablation in high risk locations: preliminary results.

Objectives: To demonstrate the effectiveness and the safety of laser thermal ablation (LTA) in patients with unresectable hepatocellular carcinoma (HCC) deemed not accessible for other percutaneous procedures (radiofrequency ablation, sclerotherapy).

Methods: From September 2003 to August 2008, 140 patients with HCC nodules were treated. In 49 patients, the lesions were localized in "critical sites".
