Dynamic assessment of venous anatomy and function in neurosurgery with real-time intraoperative multimodal ultrasound: technical note.

The relevance of the cerebral venous system is often underestimated during neurosurgical procedures. Damage to this draining system can have catastrophic implications for the patient. Surgical decision-making and planning must consider each component of the venous compartment, from the medullary draining vein to the dural sinuses and extracranial veins.

Use of Iliac Branch Device for Endovascular Treatment for Abdominal Aorta Aneurysm with Small Diameter Neck.

We present the case of a 78-year-old woman with a 4.5-cm symptomatic abdominal aortic aneurysm with a small diameter (13-mm diameter) infrarenal aortic neck who underwent endovascular treatment using an iliac branch device as a bifurcated aortic stent-graft.

Abdominal aorta aneurysm with hostile neck: Early outcomes in outside instruction for use in patients using the treovance stent graft.

Purpose: The efficacy and safety of endovascular aneurysm repair (EVAR), in patients outside instruction for use (IFU), is very challenging and widely debated. The aim of this study was to evaluate the placement of the Treovance abdominal aorta stent-graft in patients with hostile proximal necks considered outside IFU.

Materials And Methods: Between May 2013 and August 2014, 5 patients with outside IFU underwent EVAR with the Treovance stent-graft.

Endovascular treatment of a symptomatic thoracoabdominal aortic aneurysm by chimney and periscope techniques for total visceral and renal artery revascularization.

Conventional endovascular therapy of thoracoabdominal aortic aneurysm with involving visceral and renal arteries is limited by the absence of a landing zone for the aortic endograft. Solutions have been proposed to overcome the problem of no landing zone; however, most of them are not feasible in urgent and high-risk patients. We describe a case that was successfully treated by total endovascular technique with a two-by-two chimney-and-periscope approach in a patient with acute symptomatic type IV thoracoabdominal aortic aneurysm with supra-anastomotic aneurysm formation involving the renal and visceral arteries and a pseduaneurismatic sac localized in the left ileopsoas muscle.

Two-dimensional and quasi-three-dimensional dosimetry of hadron and photon beams with the Magic Cube and the Pixel Ionization Chamber.

Two detectors for fast two-dimensional (2D) and quasi-three-dimensional (quasi-3D) verification of the dose delivered by radiotherapy beams have been developed at University and Istituto Nazionale di Fisica Nucleare (INFN) of Torino. The Magic Cube is a stack of strip-segmented ionization chambers interleaved with water-equivalent slabs. The parallel plate ionization chambers have a sensitive area of 24 x 24 cm2, and consist of 0.
