Gamma Knife radiosurgery for vestibular schwannomas: Evaluation of planning using the sphericity degree of the target volume.

Introduction: This study explores the possibility of a relationship between the sphericity degree of a target volume with the dose distribution. This relationship is evaluated based on the ratio isodose volume / target volume (IV/TV) and the metrics coverage, i.e.

The role of diffusion tensor imaging tractography for Gamma Knife thalamotomy planning.

OBJECTIVE The role of tractography in Gamma Knife thalamotomy (GK-T) planning is still unclear. Pyramidal tractography might reduce the risk of radiation injury to the pyramidal tract and reduce motor complications. METHODS In this study, the ventralis intermedius nucleus (VIM) targets of 20 patients were bilaterally defined using Iplannet Stereotaxy Software, according to the anterior commissure-posterior commissure (AC-PC) line and considering the localization of the pyramidal tract.

Fetal Myelomeningocele Repair through a Mini-Hysterotomy.

Objective: To present the feasibility of fetal myelomeningocele (MMC) repair through a mini-hysterotomy and to describe the perinatal results from our initial experience.

Methods: A descriptive study of cases of fetal MMC correction via mini-hysterotomy performed between 2014 and 2016.

Results: Forty-five women underwent fetal surgery and 87% (39/45) delivered.
