Endovascular therapy has been used as an alternative treatment for vasospasm following subarachnoid hemorrhage. The effectiveness and safety of endovascular therapy are still controversial. We performed a systematic review and meta-analysis to identify any advantage of endovascular therapy over traditional medical treatment. We systematically reviewed related English publications by searching PubMed, Ovid, Cochrane library, and Web of Science up to May 2017.The risk ratios (RR) and 95% confidence intervals (CI) were synthesized with fixed effect model...

A 33-year-old man presented with aneurysmal subarachnoid hemorrhage from a ruptured, blister-type sidewall internal carotid artery (ICA) aneurysm. Balloon-assisted coiling was performed with residual neck. He subsequently developed severe vasospasm requiring intra-arterial therapies on multiple occasions, during which it was noted that despite widespread vasospasm, a focal segment of the ICA at the site of the aneurysm showed no significant spasm, suggesting underlying vessel abnormality. He was discharged without deficit and scheduled for flow diversion given concern over this potentially pathologic segment of vessel...

INTRODUCTION: Prediction of vasospasm following aneurysmal subarachnoid hemorrhage (aSAH) remains imperfect and currently relies on clinical and radiographic characteristics. Whether early hemodynamic changes may refine risk stratification for delayed vasospasm (DV) after aSAH was analyzed. METHODS: Patients with aSAH (n=53) and a control of unruptured intracranial aneurysms (UIA) (n=12) with initial color-coding angiography at admission were included in this study (n=65)...

Intracranial aneurysms (IAs) that undergo rupture causing subarachnoid hemorrhage (SAH), are common in young patients with coarctation of the aorta (CoA), but rarer in middle-aged and elderly patients. The pathogenesis of IAs associated with CoA remains unclear. We report the case of a 50-year-old woman who presented with SAH. On evaluation, six IAs were distributed among the anterior communicating artery (ACoA) (ruptured), distal segments of both anterior cerebral arteries (ACA), the left internal carotid artery (ICA), the bifurcation of the left middle cerebral artery (MCA)/MCA early branch, and the inferior trunk of the left MCA...

BACKGROUND: Continuous electroencephalography (CEEG) is a sensitive, noninvasive surrogate monitor of cerebral blood flow (CBF). Changes in CBF can be seen as changes in the frequencies on the CEEG. This case series suggests that increase in CEEG frequencies may be used to detect improved CBF following pressure augmentation such as with treatment of vasospasm from subarachnoid hemorrhage (SAH) or acute thrombosis from ischemic stroke. The application of this observation to clinical decision-making has not been clearly defined and requires further study...

BACKGROUND: Transcranial Doppler ultrasound is a standard screening tool for vasospasm after subarachnoid hemorrhage. Prevention of vasospasm-induced delayed cerebral ischemia after subarachnoid hemorrhage depends on optimization of cerebral perfusion pressure, which can be challenged by neurogenic stress cardiomyopathy. Intra-aortic balloon pumps have been utilized to augment cerebral perfusion, but they change the transcranial Doppler waveform, altering its interpretability for vasospasm screening...

Lumbar spinal fluid drainage is a common procedure for treating hydrocephalus and alleviating vasospasm by egesting blood in the subarachnoid cavity after subarachnoid hemorrhage. Despite being an effective and safe procedure, cerebrospinal fluid overdrainage might result in serious complications. Here we report the case of a 49-year-old man who suffered from tonsillar herniation with subsequent cervicothoracic syringomyelia in the acute phase of subarachnoid hemorrhage due to vertebral artery dissection. About 2 weeks after lumbar drainage was switched from external ventricular drainage initiated on the day of subarachnoid hemorrhage, the recovery from the disturbance of consciousness revealed tetraplegia, and magnetic resonance imaging demonstrated tonsillar herniation and syringomyelia...

Pathophysiology of delayed cerebral ischemia and cerebral vasospasm following aneurysmal subarachnoid hemorrhage is still poorly recognized, however free radicals are postulated as one of the crucial players. This study was designed to scrutinize whether the concentration of free radicals in the peripheral venous blood is related to the occurrence of delayed cerebral ischemia associated with cerebral vasospasm. Twenty-four aneurysmal subarachnoid hemorrhage patients and seven patients with unruptured intracranial aneurysm (control group) have been studied...

OBJECTIVE Clipping of a ruptured intracranial aneurysm requires some degree of vessel manipulation, which in turn is believed to contribute to vasoconstriction. One of the techniques used during surgery is temporary clipping of the parent vessel. Temporary clipping may either be mandatory in cases of premature rupture (rescue) or represent a precautionary or facilitating surgical step (elective). The aim of this study was to study the association between temporary clipping during aneurysm surgery and the incidence of vasospasm and delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage (aSAH) in a large clinical series...

Intracranial aneurysm is a rare cause of seizure although few cases may develop new onset seizure following rupture of aneurysm. The causes of seizure in ruptured aneurysm may be caused due to presence of subarachnoid hemorrhage, intracerebral hematoma, infarct due to progressive vasospasm, worsening of hydrocephalus, or even after surgical craniotomy for clipping of aneurysm. However, incidental aneurysm solely presenting with complex partial seizure is not reported in literature. To the best of knowledge of authors, current case represents the first case as incidental aneurysm presenting with seizure and pertinent literature is briefly reviewed...

BACKGROUND: Cerebral vasospasm (CVS) is a major determinant of prognosis in patients with subarachnoid hemorrhage (SAH). Alteration in the vascular phenotype contributes to development of CVS. However, little is known about the role of microRNAs (miRNAs) in the phenotypic alteration after SAH. We investigated the expression profile of miRNAs and the chronologic changes in the expression of microRNA-15a (miR-15a) and Kruppel-like factor 4 (KLF4), a potent regulator of vascular phenotype modulation that modulates the expression of miR-15a, in the plasma and cerebrospinal fluid (CSF) of patients with SAH...

BACKGROUND: Symptomatic vasospasm is a major cause of morbidity and mortality in subarachnoid hemorrhage patients. Hyponatremia and dehydration due to natriuresis after subarachnoid hemorrhage are related to symptomatic vasospasm. Therefore, most institutions are currently targeting euvolemia and eunatremia in subarachnoid hemorrhage patients to avoid complications. We retrospectively investigated the predictors of symptomatic vasospasm with respect to water and sodium homeostasis, while maintaining euvolemia and eunatremia after subarachnoid hemorrhage...

OBJECTIVE: One of the most serious complications following subarachnoid hemorrhage (SAH) is delayed cerebral ischemia (DCI) secondary to symptomatic vasospasm. An animal model mimicking post SAH vasospasm is essential for enabling the translation of newer technologies from the conceptual phase to animal studies, and eventually to clinical trials. Various animal models of DCI following SAH have been reported, with canine models being the most common. Due to the similarity of the swine cardiovascular system and its dimensions to the human's system, the main objective of this study was to establish a consistent and quantitatively representative model of SAH-induced vasospasm in swine...
