BACKGROUND AND PURPOSE The purpose of this study was to analyze the 3-month outcomes of patients with aneurysmal subarachnoid hemorrhage (SAH) treated from January 2005 to June 2006. This paper describes the outcomes after treatment of aneurysmal SAH and comparison between patients treated by clipping or coiling in a high volume center. MATERIALS AND METHODS A retrospective chart review was p...

Jugular venous compression by the Queckenstedt's test (Q-test) increases the intracranial pressure, but the effects of isolated jugular venous congestion are not well known. Intraventricular pressure (IVP) was compared during direct obstruction of the common jugular veins (bilateral CJV clipping) and during external compression of bilateral CJV flows (Q-test) in a rat model. Intracerebroventric...

BACKGROUND There is wide regional variation in the predominant treatment for unruptured cerebral aneurysms. We investigated the association of elective surgical clipping and endovascular coiling with mortality, readmission rate, length of stay, and discharge to rehabilitation. METHODS AND RESULTS We performed a cohort study involving patients with unruptured cerebral aneurysms, who underwent ...

BACKGROUND Publication bias and/or true heterogeneity can skew aggregate impressions from scientific literature. To better determine aggregate measures for unruptured intracranial aneurysm (UIA) treatment, we analyzed adverse outcome rates of surgical clipping and endovascular coil embolization. METHODS Two independent reviewers searched MEDLINE for studies publishing adverse outcome rates fo...

Mycorrbizal symbiosis is critical to growth of many warmseason prairie grass seedlings, but its effect on regrowth of rbizomes has not been determined. As forage species, the effect of grazing on the symbiosis is also important. when the impact of mycorrbizae on regrowth of Andropogon germ&i Vit. rhizomes was assessed, A. germ& rhizomes collected from the field and grown with mycorrbizal inocul...

INTRODUCTION Laparoscopic sleeve gastrectomy (LSG) is one of the most popular bariatric procedures. The procedure is associated with serious staple-line complications such as bleeding, leaks, and stenosis. AIM To determine whether oversewing the staple line, compared with clipping, in LSG reduces the incidence of postoperative bleeding. MATERIAL AND METHODS We conducted a parallel-group, pr...

A common approach for color image processing is to rst transform the RGB image to a new color space (such as LHS and YIQ), do the processing, and then transform back to RGB space. In many applications, only the luminance component is processed, and the hue and saturation are preserved. However, when the processed values in the new color system are transformed back to RGB, the transformed values...

BACKGROUND AND PURPOSE Practice patterns vary widely among centers with regard to the treatment of unruptured aneurysms. The purpose of the current study was to correlate outcome data with practice patterns, specifically the proportion of unruptured aneurysms treated with neurosurgical clipping versus endovascular coiling. MATERIALS AND METHODS Using the NIS, we evaluated outcomes of patients...

OBJECTIVE The purpose of this study was to determine the outcomes of surgical clipping in patients with unruptured middle cerebral artery (MCA) aneurysms. METHODS A retrospective single-center database of 125 consecutive patients with 143 small MCA aneurysms (< 10 mm) who underwent surgical clipping was reviewed from January 2007 to December 2010. Clinical outcomes were assessed based on surg...

BACKGROUND To report the authors' experience with recurrent aneurysms after primarily completely clipped cerebral aneurysms and discuss mechanisms of recurrence and recommended management. METHODS Data were available for 1016 consecutive patients who underwent clipping of ruptured and unruptured aneurysms in a 15-year period from 1993-2007. RESULTS Nine patients were treated for recurrent a...
