Endoscopic Transorbital Approaches to Anterior and Middle Cranial Fossa: A Laboratory Investigation on Surgical Anatomy and Potential Routes.

 Transorbital neuroendoscopic (TONES) approaches promise to open up new horizons for skull base surgery, offering alternative routes to reach the anterior and middle cranial fossa (ACF and MCF, respectively).  The aim of this anatomical study is to acquire new surgical anatomy knowledge and exploit it for the refinement of TONES approaches, as an alternative to open surgery, to reduce the distance to the target, and the risk of neurovascular lesions in pathological conditions extending beyond the orbital cavity.  Six head specimens (12 orbits) were studied/dissected.

A new method of real-time skin dose visualization. Clinical evaluation of fluoroscopically guided interventions.

Introduction: We have conducted a prospective study to clinically evaluate a new radiation dose observing tool that displays patient's peak skin dose (PSD) map in real time.

Methods: The skin dose map (SDM) prototype quantifies the air kerma based on exposure parameters from the X-ray system. The accuracy of this prototype was evaluated with radiochromic films, which were used as a mean for PSD measurement.

Cannabis use, ischemic stroke, and multifocal intracranial vasoconstriction: a prospective study in 48 consecutive young patients.

Background And Purpose: Our objective was to evaluate the relationship between cannabis use and ischemic stroke in a young adult population.

Methods: Forty-eight consecutive young patients admitted for acute ischemic stroke participated in the study. First-line screening was performed, including blood tests, cardiovascular investigations, and urine analysis for cannabinoids.

Relevance of the anatomical location of the Adamkiewicz artery in spine surgery.

Purpose: The aim of this study was to describe the preoperative topography of the Adamkiewicz artery and the blood supply of the lumbosacral spinal cord in patients who underwent spinal surgery. The relevance for anterior approaches of the thoracolumbar spine was then analyzed.

Methods: One hundred consecutive spinal angiographies were reviewed.

[Chronic fever revealing an urachal cyst].

In the adult, the urachus remains as a non-specific fibrous formation extended from the bladder dome to the Retzius space. This urachal remnant is commonly asymptomatic or may be revealed by a cyst. This later may also be asymptomatic or lead to local inflammation or inflammatory pseudo-tumor.
