Intraoperative fluorescence diagnostics upon recurrent operations for brain gliomas.

Unlabelled: The method of fluorescent diagnosis (FD) using 5-ALA has been widely employed in surgery of primary intracerebral tumors over the last years. The issue of FD application in surgery of gliomas with continued growth has remained less studied.

Objective: To investigate the efficacy of using FD with 5-ALA and laser spectral analysis in surgery of brain gliomas with continued growth.

Intraoperative combined spectroscopy (optical biopsy) of cerebral gliomas.

Clinical studies have revealed high selectivity of 5-ALA-induced protoporphyrin IX accumulation in different brain tumors. Modern methods of evaluation of tissues visible fluorescence are based on the qualitative analysis of the images. Up-to-date methods of combined spectral analysis allow fulfilling the intraoperative quantitative evaluation of the protoporphyrin IX content, as well as the scattering and absorption properties of a tissue.

[Modern technology in the surgical treatment of head injury sequelae].

The paper presents main types of surgically relevant posttraumatic lesions in 4136 patients with skull vault as well as skull base defects, craniofacial deformities, recurrent CSF leaks, arterio-venous fistulas, aneurysms and pseudoaneurysms etc. Classification of TBI sequelae and complications as well as its clinical course grading is presented. The use of modern neuroimaging techniques for studying pathophysiologic mechanisms and complications of TBI has been demonstrated.

[First experience of photodynamic diagnosis and laser spectroalanysis in surgery of intracranial meningiomas].

Photodynamic diagnosis (PDD) has been actively implemented into neurooncological practice, especially in cerebral gliomas surgery. This paper describes our first experience of PDD combined with laser spectroanalysis in intracranial meningiomas. The study included 21 patients (8 male and 13 female patients, mean age was 58 years, range--between 37 and 74 years) with intracranial meningiomas operated with PDD in Burdenko Neurosurgical Institute between 2008 and 2011.

[Monosymptomatic clinical course of posttraumatic normal pressure hydrocephalus].

Triad of Hakim--Adams is well known for normal pressure hydrocephalus (NPH): dementia, gait disturbances and urinary incontinence. Variability of intensity of these symptoms is obvious. However in clinical practice all classic signs are present.
