Background. Intracranial artery dissections are rare and many controversies exist about treatment options. The aim of this study was to evaluate the efficacy and safety of the endovascular approach in patients with an intracranial dissection presenting with different symptoms. Methods. We prospectively evaluated the clinical features and treatment outcomes of 30 patients who had angiographically confirmed nontraumatic intracranial dissections over 4 years. Patients were followed up for 17 months, and their final outcomes were assessed by the modified Rankin Score (mRS) and angiography. Results. Sixteen (53.3%) patients had a dissection of the anterior circulation, whereas 14 (46.7%) had a posterior circulation dissection. Overall, 83.3% of the patients suffered a subarachnoid hemorrhage (SAH). Grade IV Hunt and Hess score was seen in 32% of the SAH presenting cases. Parent artery occlusion (PAO) with coil embolization was used in 70% of the cases. The prevalence of overall procedural complications was 23.3%, and all were completely resolved at the end of follow-up. No evidence of in-stent occlusion/stenosis or rebleeding was observed in our cases during follow-up. Angiography results improved more frequently in the PAO with coil embolization group (100%) than in the stent-only-treated group (88.9%) (P = 0.310) and the unruptured dissection group (5/5, 100%) in comparison with the group that presented with SAH (95.8%) (P = 0.833). Conclusion. Favorable outcomes were achieved following an endovascular approach for symptomatic ruptured or unruptured dissecting aneurysms. However, the long-term efficacy and durability of these procedures remain to be determined in a larger series.
Hydrocephalus is a known disease from ancient times. Despite ongoing attempts to achieve optimal management of the disorder, there are still challenges for cerebrospinal fluid shunting procedures. The etiologies, diagnostic studies, surgical treatment, and a historical review of hydrocephalus are presented. ANATOMY AND PHYSIOLOGYUnder normal circumstances, ultrafiltration through capillary endothelial walls of choroids plexus produces CSF. Na/K ATPase, on the apical membrane of choroids plexus epithelium plays the decisive role in CSF secretion. 9-11 Much of the secreted fluid is reabsorbed
Background & Aim: Traumatic brain injury is one of the main causes of death and disability. The aim of this study is to systematically review the articles which assessed some serum factors of traumatic brain injury patients in relation to their outcomes. Methods & Materials/Patients: Databases were searched for relevant publications from 2005 to 2014. Selection criteria were:Studies which evaluate the factors affecting the outcome after TBI, TBI defined as "acute changes in brain function resulting in a strong external force to the head".Resultswere measured by Glasgow Outcome Score or a comparable measure.Factors were measured in first month after injury and the prognosis was addressed. All papers were checked and approved by a specialist and expert in that field. A systematic review was performed for prognostic factors. Results: Sixty-three studies were included. Most studies used Glasgow Outcome Score at 6 months post-injury as outcome measure, sometimes in combination with other outcome measures. Strong evidence for predicting outcome was found for serum concentration of S100 protein, NSE, MBP, NF-H, GFAP, UCH-L1, blood glucose levels, serum levels of LDH, sodium level, prothrombin time, partial thromboplastin time, platelet count, D.dimer, HSP 70, serum levels of IL-8, number of circulating EPCs, and DNA levels in serum. Moderate evidence for predicting outcome was found for high serum MMP9. Strong evidence of no association was found for WBC count and serum cortisol levels. Moderate evidence of no association was found for serum total cholesterol for other determinants, inconclusive or no evidence or limited evidence was found. Conclusion: S100 protein, NSE, MBP, NF-H, GFAP, UCH-L1, blood glucose levels, serum levels of LDH, sodium level, prothrombin time, Partial thromboplastin time, platelet count, D.dimer, HSP 70, serum levels of IL-8, number of circulating EPCs, and DNA levels in serum predicted outcome after traumatic brain injury. WBC count, serum cortisol levels, total cholesterol and MMP9 did not have predictive value.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
