Middle cerebral artery (MCA) aneurysm is a serious medical condition mainly occurring in the proximal and bifurcation tracts. Evidence has indicated that endovascular treatment is an effective surgical method for patients with MCA aneurysm. In the present study, the efficacy of endovascular treatment with low-profile visualized intraluminal support (LVIS) stent for MCA aneurysms was evaluated in comparison with that using a non-LVIS stent device. A total of 92 patients who underwent endovascular treatment of MCA aneurysms with LVIS stent or non-LVIS stent were included in the present study. The clinical presentation, aneurysmal characteristics, technical feasibility, procedural complications, as well as angiographic and clinical follow-up results were analyzed. The computed tomography scan demonstrated that endovascular treatment with LVIS stent markedly reduced pre-operative and intra-operative ruptures. It was indicated that endovascular treatment with LVIS stent resulted in less post-operative symptoms and cases of disability according to the modified Rankin scale score. In conclusion, the present outcomes provide evidence that endovascular treatment with an LVIS stent is an efficient method for the treatment of MCA aneurysm.

“…38 A previous study applying a Rasch (1parameter IRT) model to GOSE data collected from patients with remote mild-to-moderate TBIs suggested that the GOSE does not precisely measure the effect of injury on day-to-day activities and participation in this population. 41 However, this study had a small sample size for analyses of this nature (N = 89), studied patients much farther out from injury than is typical for clinical trials endpoints (M = 2.7 years), and did not consider a broader array of IRT models. In particular, whereas 1-parameter models only quantify item difficulty (e.g., level of severity of TBI-related disability needed to expect an item to be endorsed), 2parameter models additionally allow items to vary in the degree to which they differentiate (discriminate) between patients differing in disability at the item's severity level.…”

The Glasgow Outcome Scale -Extended (GOSE) was designed to assess global outcome following traumatic brain injury (TBI). Since its introduction, several empirically founded criticisms of the GOSE have been raised, including poor reliability; an insensitivity to small but potentially meaningful changes; a tendency to produce ceiling effects; inconsistent associations with neurocognitive, psychological, and quality of life measures; and an inability to assess the multidimensional nature of TBI outcome. The current project took a diagnostic approach to identifying the underlying causes of reported limitations by exploring the internal construct validity of the GOSE at 3 and 6 months post-injury using item response theory (IRT) techniques. Data were from the TRACK-TBI Pilot Study, a large (N = 586), prospective, multisite project that included TBI cases of all injury severity levels.To assess the level of latent functional "impairment" captured by GOSE items independent of the assigned outcome category or GOSE total score, items were modified so that higher scores reflected greater impairment. Results showed that although the GOSE's items capture varying levels of impairment across a broad disability spectrum at 3 and 6 months, there was also evidence at each time point of item redundancy (multiple items capturing similar levels of impairment), item deficiency (lack of items capturing lower levels of impairment), and item inefficiency (items only capturing minimal impairment information).The findings illustrate the value of IRT to illuminate strengths and weaknesses of clinical outcome assessment measures and provide a framework for future measure refinement.
