OBJECTIVE: More nonaneurysmal subarachnoid hemorrhage (NaSAH) are 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...

Purpose Repeat imaging in patients with non-aneurysmal subarachnoid hemorrhage (NASAH) remains controversial. We aim to report our experience with NASAH with different hemorrhage patterns, and to investigate the need for further diagnostic workup to determine the underlying cause of hemorrhage. Method We conducted a retrospective analysis of all spontaneous SAH with an initial negative computed tomography (CT) with angiography (CTA) and/or digital subtraction angiography (DSA) from October 2011 through May 2017...

OBJECTIVE: The number of patients with nonaneurysmal subarachnoid hemorrhage (naSAH) has increased during the last decade. Data regarding infarctions in naSAH are still limited. The aim of this study was to identify the rate of cerebral vasospasm (CVS)-dependent and CVS-independent infarctions and their influence on clinical outcomes. METHODS: Between 1999 and 2015, 250 patients suffering from naSAH were analyzed retrospectively. A delayed infarction was analyzed whether it was associated with CVS (CVS-dependent infarction) or not (CVS-independent)...

Background. The ideal management of SAH patients with negative initial DSA findings remains unresolved. Objective. (i) To present risk factors, clinical courses, and outcomes in different types of SAH patients with negative DSA findings; (ii) to explore the differences of basal vein between aSAH patients and NASAH patients; and (iii) to evaluate the value of repeated DSA for these patients. Methods. All SAH patients with negative initial DSA findings between 2013 and 2015 in our hospital were enrolled and were further categorized as perimesencephalic SAH (PMN-SAH) or nonperimesencephalic SAH (nPMN-SAH)...

BACKGROUND: Up to 15% of all spontaneous subarachnoid hemorrhages (SAH) have a non-aneurysmal SAH (NASAH). The evaluation of SAH patients with negative digital subtraction angiography (DSA) is sometimes a diagnostic challenge. Our goal in this study was to reassess the yield of standard MR-imaging of the complete spinal axis to rule out spinal bleeding sources in patients with NASAH. METHODS: We retrospectively analyzed the spinal MRI findings in 190 patients with spontaneous NASAH, containing perimesencephalic (PM) and non-perimesencephalic (NPM) SAH, diagnosed by computer tomography (CT) and/or lumbar puncture (LP), and negative 2nd DSA...

BACKGROUND: Stress-induced hyperglycemia (SIH) after acute cerebrovascular disease is common and is associated with adverse clinical outcomes. The incidence of SIH after spontaneous subarachnoid hemorrhage (SAH) and its role in shunt placement have not been systematically investigated. The present study is designed to investigate the incidence of SIH after spontaneous SAH and its determinants. The role of SIH and premorbid hyperglycemia (using glycated hemoglobin [HbA1c]) in predicting external ventricular drainage (EVD) and ventriculoperitoneal shunt (VPS) placement is also investigated...

OBJECTIVE: Recent data have shown increasing numbers of non-aneurysmal subarachnoid hemorrhage (NASAH). However, data are limited and often only small series have been published. Our objective was to analyze the rate of cerebral vasospasm (CVS), delayed cerebral infarction (DCI), and their influence on the clinical outcome, especially in patients with diffuse Fisher 3 bleeding pattern NASAH (Fi3). METHODS: Between 1999 and 2014, 225 patients had NASAH. CVS, DCI, and outcome (according to the modified Rankin Scale at 6 months) were analyzed retrospectively...

OBJECT Subarachnoid hemorrhage (SAH) is usually caused by a ruptured intracranial aneurysm, but in some patients no source of hemorrhage can be detected. More recent data showed increasing numbers of cases of spontaneous nonaneurysmal SAH (NASAH). The aim of this study was to analyze factors, especially the use of antithrombotic medications such as systemic anticoagulation or antiplatelet agents (aCPs), influencing the increasing numbers of cases of NASAH and the clinical outcome. METHODS Between 1999 and 2013, 214 patients who were admitted to the authors' institution suffered from NASAH, 14% of all patients with SAH...

Subarachnoid hemorrhage (SAH) is divided into two major types (aneurysmal [ASAH] and nonaneurysmal [NASAH]) because, in approximately 15% of the patients who experience SAH, no source of hemorrhage can be identified. Anecdotal evidence and contradictory research suggest that patients with NASAH experience some of the same health-related quality of life (HRQOL) issues as patients with ASAH. This quantitative survey design study compared 1-3 years after hemorrhage the HRQOL in patients who had experienced an NASAH with those who had experienced an ASAH...

Contrary to aneurysmal bleeding, non-aneurysmal non-traumatic subarachnoid hemorrhage (NASAH) is rarely associated with unfavorable clinical outcome, cerebral infarction and vasospasm. We aimed to identify independent predictors for a poor clinical course and outcome after NASAH. All patients with NASAH treated at our institution between January 2005 and December 2012 were retrospectively analyzed. Collected demographic, clinical and radiographic variables were divided into primary (admission) and secondary (follow-up) parameters...

BACKGROUND: Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PM-NASAH) is characterized by a benign course compared with aneurysmal SAH. While vasospasm (VS) after aneurysmal SAH is considered responsible for serious complications, VS post-PM-NASAH is not well documented. Our purpose was to characterize the incidence and course of VS among 63 patients--one of the largest databases of PM-NASAH patients with documented blood flow velocities in the literature. METHODS: Data from 63 patients that were admitted with PM-NASAH from 2000 to 2012 and underwent transcranial Doppler tests to assess cranial vessel flow velocity was analyzed...

OBJECTIVE: Subarachnoid haemorrhage (SAH) may present with coma and this is known to be associated with aneurysmal origin and blood load. Aneurysmal origin is associated with increased blood load and existing data do not allow us to determine if the association between coma and aneurysmal SAH is wholly due to blood load or if aneurysmal origin has an additional independent effect. The objective of our study is to find if an aneurysmal origin is a predictor of acute onset of coma independent of blood load...

BACKGROUND: Although, the relationship of spontaneous subarachnoid hemorrhage (SAH) to climatic or circadian factors has been widely studied, epidemiologic, circardian and climatic factors in non-aneurysmal SAH (naSAH), particularly perimesencephalic SAH (PMH), has not been reported before. OBJECTIVE: For the first time, demographic, climatic, and circadian variables are examined together as possible contributing factors comparing aSAH and naSAH. METHODS: We reviewed records for 384 patients admitted to University of Wisconsin Neurosurgery Service from January 2005 to December 2010 with spontaneous non-traumatic SAH...

A case-control study of 1358 pregnant and nonpregnant women with and without symptoms of a lower genital tract infection were investigated for evidence of venereal disease. The prevalence of gonorrhea, Trichomonas and Candida in pregnancy was 15.0%, 20.6% and 41.3%, respectively, while the equivalent percentages in the nonpregnant women varied from 16.5% to 21.6%, 2.4% to 22.8% and 33.3% to 39.3%. However, these differences are not statistically significant. The implications of the findings are discussed and a screening program suggested...
