Endovascular Therapy for Erectile Dysfunction-Who Benefits Most? Insights From a Single-Center Experience.

Purpose: To report the 1-year outcomes of a single-center, all-comers registry aimed to assess effectiveness and safety of endovascular revascularization for atherosclerotic erectile dysfunction (ED) in an unselected patient cohort.

Materials And Methods: Between April 2016 and October 2017, 50 consecutive patients (mean age 59.6±10.

Morphometric analysis of lumbar pedicles in patients with spinal dysraphism.

Background: In patients with open neural tube defects, the incidence of scoliosis and requirement for spinal fusions are increased. Historically, there has been no standardized measurement of vertebral morphometry in these patients. However, anecdotally, patients with open neural tube defects have a more medially oriented lumbar pedicle trajectory than the average population.

Magnetic resonance imaging appearance and changes on intracavitary Gliadel wafer placement: A pilot study.

Aim: To investigate changes on magnetic resonance imaging (MRI) which occur with intracavitary Gliadel wafer placement in patients with glioblastoma multiforme (GBM).

Methods: This retrospective Health Insurance Portability and Accountability Act-compliant study was approved by the institutional review board, with a waiver of informed consent. A total of eight patients aged 29-67 years with GBM underwent Gliadel wafer placement.

Analysis of visual toxicity after gamma knife radiosurgery for treatment of choroidal melanoma: identification of multiple targets and mechanisms of toxicity.

Objectives: Identification of the targets of radiation damage after radiosurgical treatment of ocular melanoma will potentially allow for sparing of vision with improved treatment planning.

Materials And Methods: Six patients with ocular melanoma, who had useful vision before therapy, were treated with gamma knife stereotactic radiosurgery with curative intent. Dosimetric analysis of functional targets of radiation damage including the fovea, optic nerve, lens, and iris was carried out.

Crescent sign on magnetic resonance angiography revealing incomplete stent apposition: correlation with diffusion-weighted changes in stent-mediated coil embolization of aneurysms.

Object: Few data are available on how closely stents appose the luminal vessel wall in stent-mediated coil embolization of intracranial aneurysms and on the effect of incomplete stent apposition on procedural thromboembolic complications.

Methods: Postprocedural 3-T MR diffusion-weighted imaging and time-of-flight angiography were obtained in 58 patients undergoing stent-mediated coil embolization of aneurysms using the Enterprise closed-cell and Neuroform open-cell self-expanding intracranial microstents.

Results: A distinctive semilunar signal pattern, identified using 3-T MR angiography, represented flow outside the confines of the stent struts in patients in whom Enterprise but not Neuroform devices were used.
