CTA Supplemented by CTP Increases Interrater Reliability and Endovascular Treatment Use in Patients with Aneurysmal SAH.

Background And Purpose: Cerebral vasospasm is a common complication of aneurysmal SAH and remains a risk factor for delayed cerebral ischemia and poor outcome. The interrater reliability of CTA in combination with CTP has not been sufficiently studied. We aimed to investigate the reliability of CTA alone and in combination with CTP in the detection of cerebral vasospasm and the decision to initiate endovascular treatment.

Influence of rapidly oscillating inspired O and N concentrations on pulmonary vascular function and lung fluid balance in healthy adults.

Aircrew may experience rapidly oscillating inspired O2/N2 ratios owing to fluctuations in the on-board oxygen delivery systems (OBOG). Recent investigations suggest these oscillations may contribute to the constellation of physiologic events in aircrew of high-performance aircraft. Therefore, the purpose of this study was to determine whether these "operationally-relevant" environmental challenges may cause decrements in measures of pulmonary vascular physiology.

Single-Center Retrospective Comparative Study Evaluating the Benefit of Computed Tomography Angiography Prior to Prostatic Artery Embolization.

Purpose: To explore whether a computed tomography angiography (CTA) of the pelvis prior to prostatic artery embolization (PAE) is a beneficial preprocedural planning tool regarding the technical success.

Materials And Methods: Eighty patients with lower urinary tract symptoms treated with PAE were analyzed retrospectively. Forty of these patients received a CTA of the pelvis prior to the procedure (Group A) and were compared to 40 patients who were treated with PAE without prior CT imaging (Group B).

Relation of Intravascular Volume Profiles to Heart Failure Progression and Clinical Outcomes.

Heart failure (HF) commonly progresses over time and identifying differences in volume profiles may help stratify risk and guide therapy. The aim of this study was to assess the pathophysiologic and prognostic roles of volume profiles for HF progression in stable ambulatory and hospitalized patients. HF patients who had undergone quantitative intravascular volume analysis (185 outpatients and 139 inpatients) were retrospectively assessed for the combined end point of HF-related hospital admissions (outpatients), HF-readmissions (inpatients), and overall all-cause mortality.
