Despite the adverse effects and unclear benefit of the complete 21-day course of nimodipine therapy, The Joint Commission mandates adherence to nimodipine treatment for 21 days after hemorrhage or after hospital discharge if discharged within 21 days for Comprehensive Stroke Center (CSC) certification. We hereby present a 67 year-old male patient with Hunt-Hess grade 2 and Fisher grade 3 non-aneurysmal spontaneous subarachnoid hemorrhage who was discharged with oral nimodipine as stipulated by the CSC guidelines, and subsequently developed symptomatic hypotension...

It is very difficult to predict some complications after subarachnoid hemorrhage (SAH), despite rapid advances in medical science. Herein, we introduce a label-free cellulose surface-enhanced Raman spectroscopy (SERS) biosensor chip with pH-functionalized, gold nanoparticle (AuNP)-enhanced localized surface plasmon resonance (LSPR) effects for identification of SAH-induced cerebral vasospasm and hydrocephalus caused by cerebrospinal fluid (CSF). The SERS biosensor chip was implemented by the synthesis reaction of the AuNPs, which were charged positively through pH level adjustment, onto a negatively-charged cellulose substrate with ξ = -30...

The anterior communicating artery is a common location for intracranial aneurysms. Compared to surgical clipping, endovascular coiling has been shown to improve outcomes for patients with ruptured aneurysms and we have seen a paradigm shift favoring this technique for treating aneurysms. Access to the anterior cerebral artery can be challenging, especially in patients with tortuous anatomy or subarachnoid hemorrhage or in patients presenting with vasospasm. We present a technique for cannulating the anterior cerebral artery using a balloon inflated in the proximal middle cerebral artery as a rebound surface...

Non-traumatic subarachnoid hemorrhage (SAH) affects an estimated 30,000 people each year in the United States, with an overall mortality of ~30%. Most cases of SAH result from a ruptured intracranial aneurysm, require long hospital stays, and result in significant disability and high fatality. Early brain injury (EBI) and delayed cerebral vasospasm (CV) have been implicated as leading causes of morbidity and mortality in these patients, necessitating intense focus on developing preclinical animal models that replicate clinical SAH complete with delayed CV...

OBJECTIVE: A growing number of non-aneurysmal subarachnoid hemorrhage (NaSAH) were found in clinical practice. However, the precise mechanisms in which D-dimer level is associated with clinical condition in patients with NaSAH remain unclear. But even more, the data assessing the risk of clinical course in the patients with NaSAH are scarce. Our objective was to investigate whether D-dimer levels correlated with complication and outcome in patients with NaSAH. METHODS: Between February 2013 and May 2017, 92 patients suffering from NaSAH were treated in our hospital...

Blood-brain barrier (BBB) dysfunction has been implicated in ischemic risk following aneurysmal subarachnoid hemorrhage (aSAH), but never directly imaged. We prospectively examined whether post-bleed day 4 dynamic contrast-enhanced magnetic resonance (DCE-MR) BBB permeability imaging could predict development of delayed cerebral ischemia (DCI). Global MR-derived BBB permeability ( Ktrans ) was significantly higher in aSAH patients who subsequently developed DCI (five patients; 2.28 ± 0.09 × 10-3 min-1 ) compared to those who experienced radiographic vasospasm only (three patients; 1...

BACKGROUND: Milrinone is an inotropic and vasodilatory drug proven safe for use in the treatment of cerebral vasospasm. Despite its reported safety profile, its use is not free of side effects. Milrinone-associated cardiomyopathy and arrhythmia can occur in patients with cerebral vasospasm. CASE DESCRIPTION: This is a retrospective chart review of a patient who presented with aneurysmal subarachnoid hemorrhage and developed clinical vasospasm twice over a period of two weeks...

We retrospectively compared the outcome of aneurysmal subarachnoid hemorrhage (aSAH) patients treated in a neurosurgical ICU (nICU) between 1990 and 2005 with that of patients treated in a general ICU (gICU) between 2005 and 2013 with almost identical treatment strategies. Among other parameters, we registered the initial Hunt and Hess grade, Fisher score, the incidence of vasospasm, and outcome. A multivariate analysis (logistic regression model) was performed to adjust for different variables. In total, 755 patients were included in this study with 456 patients assigned to the nICU and 299 patients to the gICU...

Aneurysmal subarachnoid hemorrhage (aSAH) represents 3% of all strokes in the US. When the patient survives it can lead to permanent incapacity especially if the patient develops vasospasm. The vasospasm is a multifactorial disorder and can lead to delayed cerebral ischemia (DCI). Most of the drugs tested to treat vasospasm failed to improve outcome and the only exception is nimodipine. Areas covered: In this review, the authors describe the multifactorial process of vasospasm leading DCI after aSAH, discussing the treatments available based on the past and latest researches...

Background Delayed cerebral vasospasm (dCVS) following aneurysmal subarachnoid hemorrhage (aSAH) is (next to possible aneurysm rebleeding, cortical spreading depression and early brain injury) one of the main factors contributing to poor overall patient outcome. Since decades intensive research has been ongoing with the goal of improving our understanding of the pathophysiological principles underlying dCVS. Endothelin-1 (ET-1) and prostaglandin F2 alpha (PGF2a) seem to play a major role during dCVS. The synthesis of ET-1 is enhanced after subarachnoid hemorrhage (SAH) to mediate a long-lasting vasoconstriction, and PGF2a contributes to cerebral inflammation and vasoconstriction...

Patients presenting with spontaneous, non-aneurysmal subarachnoid hemorrhage (SAH) achieve better outcomes compared to patients with aneurysmal SAH. Nevertheless, some patients develop shunt-dependent hydrocephalus during treatment course. We therefore analyzed our neurovascular database to identify factors determining shunt dependency after non-aneurysmal SAH. From 2006 to 2016, 131 patients suffering from spontaneous, non-aneurysmal SAH were admitted to our department. Patients were stratified according to the distribution of cisternal blood into patients with perimesencephalic SAH (pSAH) versus non-perimesencephalic SAH (npSAH)...

OBJECTIVE: There has been controversy as to whether intraventricular hemorrhage (IVH) after aneurysmal subarachnoid hemorrhage (SAH) contributes to angiographic cerebral vasospasm (aCV) and delayed cerebral ischemia (DCI). CT-based SAH scales that did and did not consider IVH were compared in terms of ability to predict aCV, DCI, and outcome. METHODS: We reviewed 390 patients with ruptured aneurysms who had been treated surgically by day 3 by the same surgeon (T...

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...

BACKGROUND: Delayed cerebral ischemia (DCI) is the major cause of lethality and neuronal damage in patients who survived the primary subarachnoid hemorrhage (SAH). Asymmetric and symmetric dimethylarginines (ADMA and SDMA) inhibit nitric oxide production from L-arginine via distinct mechanisms. Elevated ADMA levels are associated with vasospasm after SAH. We aimed to study the time course of ADMA and SDMA in plasma and ventricular cerebrospinal fluid (CSF) and their associations with DCI and outcome...

In recent years, the so-called primary or preventive decompressive craniectomy (DC) has been increasingly used in patients with aneurysmal subarachnoid hemorrhage (SAH). The main goal of the technique is prevention of refractory intracranial hypertension (ICH) and its consequences. PURPOSE: The study purpose was to define the CT criteria for reasonability and efficacy of DC as well as clarification of the indications for preventive DC in patients with SAH after microsurgical aneurysm exclusion...

Objective Cerebral vasospasm(CVS) after Subarachnoid hemorrhage (SAH) can cause delayed cerebral ischemia,secondary cerebral infarction, and rehemorrhage, which are the leading causes of mutilation and death. Nimodipine has been shown to prevent CVS. Magnesium ion (Mg2+ ) can competitively inhibit the influx of calcium (Ca2+ ) and prevent vasospasm. There is evidence that magnesium sulfate can prevent CVS and reduce infarct volume after SAH. In this study, we evaluated the efficacy and safety of intravenous magnesium sulfate combined with oral nimodipine on CVS, delayed cerebral ischemia, secondary cerebral infarction, and rehemorrhage after SAH...

Despite advancements in treating ruptured cerebral aneurysms, an aneurysmal subarachnoid hemorrhage (aSAH) is still a grave cerebrovascular disease associated with a high rate of morbidity and mortality. Based on the literature published to date, worldwide academic and governmental committees have developed clinical practice guidelines (CPGs) to propose standards for disease management in order to achieve the best treatment outcomes for aSAHs. In 2013, the Korean Society of Cerebrovascular Surgeons issued a Korean version of the CPGs for aSAHs...

PURPOSE: Perimesencephalic hemorrhage (PMH) is a benign subtype of nonaneurysmal subarachnoid hemorrhage (SAH). We aimed to investigate if cerebral perfusion in PMH is less affected than in aneurysmal SAH (aSAH). METHODS: From a prospective cohort of 80 patients with spontaneous SAH, we included PMH patients (n = 15) and selected aSAH patients (n = 39) with similar clinical grade at admission (World Federation of Neurosurgeons Scale-WFNS I/II). Computed tomography (CT) perfusion was performed at < 72 h and/or at 8-10 days...
