PURPOSE: Using high-quality CT-on-rails imaging, the daily motion of the prostate bed clinical target volume (PB-CTV) based on consensus Radiation Therapy Oncology Group (RTOG) definitions (instead of surgical clips/fiducials) was studied. It was assessed whether PB motion in the superior portion of PB-CTV (SUP-CTV) differed from the inferior PB-CTV (INF-CTV). PATIENTS AND METHODS: Eight pT2-3bN0-1M0 patients underwent postprostatectomy intensity-modulated radiotherapy, totaling 300 fractions...

BACKGROUND: It is believed that most of thrombi form in the left atrial appendage (LAA)before they emboli. Different surgical and percutaneouse approaches were suggested to manage the LAA. In this study we are evaluating the safety of clipping the LAA via minithoractotomy approach. METHOD: All consecutive patients who had minimally invasive mitral valve surgery with concomitant LAA clipping between December 2012 and February 2014 were included in the study. LAA exclusion was performed using AtriClip® LAA Exclusion System (Cincinnati, Ohio, AtriCure®)...

Posterior cerebral artery (PCA) aneurysms are rare, and direct surgery of these is considered difficult. Coil embolization of PCA aneurysms is becoming popular. However, it is difficult to completely obliterate the aneurysm while preserving the flow of the parent artery in large or giant PCA aneurysms with a wide neck with this technique. We report a case of a large and wide-necked PCA aneurysm with multiple recurrences following successful surgical clipping and coil embolization.A 77-year-old man with a large unruptured right PCA (P2) aneurysm was successfully treated by surgical clipping...

OBJECTIVE: Partial-breast irradiation (PBI) with external-beam radiotherapy has produced higher than expected rates of fair-to-poor cosmesis. Worsened outcomes have been correlated with larger volumes of breast tissue exposed to radiation. A novel breast-specific stereotactic radiotherapy (BSRT) device (BSRTD) has been developed at our institution and has shown promise in delivering highly conformal dose distributions. We compared normal tissue sparing with this device with that achieved with intensity-modulated radiation therapy (IMRT)-PBI...

The anterior petroclinoid fold (APF) is a ligamentous structure consisting of collagen fiber and extends from the petrous apex to the anterior clinoid process. During the surgical clipping of some posterolaterally projecting posterior communicating artery aneurysms, it may pose a technical challenge due to obscuration of the aneurismal neck by the APF. Herein, the authors describe a simple and effective technique utilizing fenestration of the APF to facilitate visualization and surgical clipping of these aneurysms...

Spinal cord injury (SCI) causes permanent changes in motor, sensory and autonomic functions. Unfortunately, there are not a stable cures and current treatments include surgical decompression, methylprednisolone and hemodynamic control that lead to modest function recovery. Fumaric acid esters (FAEs) were firstly used in the management of an immunological skin disorder, such as psoriasis. Because of their potent anti-inflammatory effects, they have been introduced in multiple sclerosis. Investigation shown not only anti-inflammatory, but also supposed neuroprotective mechanism of action...
