Posterior Septal Resection

Local resection of posterior uveal melanoma.

Internal resection of posterior uveal melanomas.

AIMS To evaluate the safety and efficacy of internal resection in the treatment of malignant melanoma of the choroid. METHODS 32 consecutive patients with histopathologically proved malignant choroidal melanomas were treated with internal resection. 29 of the 32 (90.6%) tumours were within 2 disc diameters of the optic nerve or fovea. The surgery was performed at two university centres by one...

A single posterior approach for vertebral column resection in adults with severe rigid kyphosis

 Abstract Background: Correction of severe kyphosis is a challenging operation in spinal surgery. A two stage operation has been commonly used: anterior release and decompression followed by posterior correction and fusion. We describe the posterior vertebral osteotomy technique for correction of severe and rigid kyphosis through posterior-only approach. Methods: Twelve patients (six male and s...

Posterior deviation of left ventricular outflow tract septal components without ventricular septal defect.

OBJECTIVE To describe 11 patients with narrowing of the left ventricular outflow tract caused by angular posterior deviation of both the outlet septum and the upper part of trabecular septum, which was diagnosed by cross sectional echocardiography in all and confirmed by angiocardiography in seven. RESULTS Four patients had a subaortic systolic pressure gradient ranging from 23 to 70 mm Hg by...

Robotic trans-atrial and trans-mitral ventricular septal resection.

Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morro...
