The dual microcatheter technique is an alternative treatment for stent-assisted coiling in acutely ruptured wide-necked aneurysms because of no antiplatelet therapy. We assessed the safety and efficacy of this technique in ruptured wide-necked aneurysms. Between March 2008 and March 2016, 56 acutely ruptured aneurysms were treated with the dual microcatheter technique. The angiographic results, treatment-related complications, and clinical outcome were documented. Angiographic follow-up was available in 37 patients at a mean of 20...

OBJECTIVE: Accurate identification of patients who will achieve a favorable outcome is almost impossible preoperatively or postoperatively in poor-grade (Hunt and Hess Grade IV and V) aneurysmal subarachnoid hemorrhage (SAH). Whether characteristics of blood pressure profiles during the first 24 hours after endovascular coiling could predict prognosis in poor grade patients was explored. METHODS: Data were retrospectively obtained on all patients undergoing endovascular treatment with poor-grade SAH from Nov...

OBJECTIVE: Spontaneous subarachnoid hemorrhage is mostly caused by the rupture of an aneurysm. Neurogenic stunned myocardium (NSM) is one of the most frequent complications caused by aneurysmal subarachnoid hemorrhage (aSAH). The possible pathogenesis of NSM may be that the catecholamine peak resulting from aSAH leads to subendocardial ischemia or coronary artery spasm. We designed this meta-analysis to find out whether beta-blockers (BB) can significantly reduce the incidence of NSM and improve the outcomes of aSAH...

Fatal abusive head trauma is a major cause of death in children and toddlers who suffer from cruel physical abuse. Postmortem differentiation of fatal abusive head trauma from accidental head trauma can be a complicated process. This consecutive case series study aimed to determine the role of subdural optic nerve sheath hemorrhage (ONSH) in 70 autopsy cases of children ≤3 years old in making this differentiation. The study took place over a 13 year period (between August 1st 2003 and July 31st 2016) at a tertiary hospital in Thailand...

OBJECTIVE: After aneurysmal subarachnoid hemorrhage (aSAH), prognosis is affected heavily by the presence of delayed cerebral ischemia (DCI). There is growing recognition of ultra-early angiographic vasospasm (UEAV) occurring within 48 hours of aSAH; however, its relationship with DCI and ultimately prognosis remains unclear. METHODS: Various databases limited to the English language through September 2016 were searched systematically. Eligible studies were those comparing UEAV with control non-UEAV outcomes and follow-up...

Successful endovascular coiling of ruptured tiny saccular intracranial aneurysms (⩽3mm) is technically challenging and traditionally has been associated with technical failures, as well as morbidity related to thromboembolic events and high intraoperative rupture rates. This study analyzes the feasibility, technical efficacy, and clinical outcomes of coil embolization of ruptured tiny intracranial aneurysms using current coil and microcatheter technology and techniques. We performed a retrospective review of 20 patients with 20 ruptured tiny aneurysms treated with endovascular coil embolization from 2013 to 2016 at a single high-volume academic tertiary care practice...

Tobacco smoke increases the risk of aneurysmal subarachnoid hemorrhage (SAH), as well as complications such as vasospasm. Most patients presenting with aneurysmal SAH smoke, and many survivors continue to smoke after discharge. Neurosurgeons often hesitate to use nicotine replacement therapy (NRT) during hospitalization of patients with SAH due to concerns of inducing vasospasm. We aimed to evaluate the safety and efficacy, and patterns of use of NRT in smokers hospitalized for SAH. We performed a systematic review of MEDLINE, CENTRAL, Embase, and unpublished sources of literature to October 2016 for randomized and observational studies comparing exposure to non-exposure of smoking cessation products in the acute phase of aneurysmal SAH...

BACKGROUND AND PURPOSE: Recent studies have suggested that the use of low-dose aspirin may reduce the risk of aneurysmal subarachnoid hemorrhage (aSAH). We aimed to evaluate any association between aspirin use and risk of aSAH based on the literature, and whether this is influenced by duration or frequency of aspirin use. METHODS: A search of electronic databases was done from inception to September 2016. For each study, data on risk of aSAH in aspirin versus nonaspirin users were used to generate odds ratios and 95% confidence intervals, and combined using inverse variance-weighted averages of logarithmic odds ratios in a random-effects models...

Balloon angioplasty is often performed for symptomatic vasospasm following aneurysmal subarachnoid hemorrhage. Angioplasty of the anterior cerebral artery (ACA), however, is perceived to be a challenging endeavor and not routinely performed due to technical and safety concerns. Here, we evaluate the safety and efficacy of balloon angioplasty of the anterior cerebral artery for vasospasm treatment. Patients with vasospasm following subarachnoid hemorrhage who underwent balloon angioplasty at our institution between 2011 and 2016 were retrospectively reviewed...

BACKGROUND: Subarachnoid hemorrhage (SAH) is associated with higher mortality in the acute phase than other stroke types. There is a particular risk of early and devastating re-bleeding. Patients therefore need urgent assessment in a neurosurgical department, and the shorter the time from symptom onset to diagnosis the better. CASE PRESENTATION: The Norwegian Acute Stroke Pre-hospital Project (NASPP) has developed a Mobile Stroke Unit (MSU) model, which is staffed with anesthesiologists also trained in pre-hospital clinical assessment of acute stroke patients and interpretation of computerized tomography (CT)...

OBJECTIVE: Many new endovascular devices have been used under the guidance of the International Subarachnoid Aneurysm Trial (ISAT). Clipping still offers higher occlusion rates, and its technique continues to evolve, resulting in smaller exposures and reduced manipulation to brain tissue. We sought to evaluate the routine use of the minisphenoidal approach to manage intracranial aneurysms in a high-volume institution. METHODS: We retrospectively reviewed our database of aneurysm patients from October 2013 to May 2016...
