The venous delay phenomenon in computed tomography angiography: a novel imaging outcome predictor for poor cerebral perfusion after severe aneurysmal subarachnoid hemorrhage.

The venous delay phenomenon in computed tomography angiography: a novel imaging outcome predictor for poor cerebral perfusion after severe aneurysmal subarachnoid hemorrhage. J Neurosurg. 2017 Nov 24;:1-7 Authors: Hsieh PC, Wu YM, Wang AY, Chen CC, Chang CH, Chin SC, Wu TE, Wu CT, Lee ST Abstract OBJECTIVE Diverse treatment results are observed in patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH). Significant initial perfusion compromise is thought to predict a worse treatment outcome, but this has scant support in the literature. In this cohort study, the authors correlate the treatment outcomes with a novel poor-outcome imaging predictor representing impaired cerebral perfusion on initial CT angiography (CTA). METHODS The authors reviewed the treatment results of 148 patients with poor-grade aSAH treated at a single tertiary referral center between 2007 and 2016. Patients with the "venous delay" phenomenon on initial CTA were identified. The outcome assessments used the modified Rankin Scale (mRS) at the 3rd month after aSAH. Factors that may have had an impact on outcome were retrospectively analyzed. RESULTS Compared with previously identified outcome predictors, the venous delay phenomenon on initial CTA was found to have the strongest correlation with posttreatment outcomes on both univariable (p

In conclusion, isoflurane protected against BBB disruption caused by carbogen inhalation in mice and rats, but unlike isoflurane-mediated protection against ischemic BBB disruption, the effect could not be explained by anesthesia-induced hypothermia.

ConclusionBPV during transport was not associated with mortality. However, high standard deviation in systolic blood pressure during transport was associated with lower HD5GCS in patients with intraparenchymal hemorrhage. Further studies are needed to confirm our observations.

CONCLUSION: Early embolization of tiny cerebral aneurysms within 72 h of subarachnoid hemorrhage is safe and effective compared with ruptured large aneurysms treated in the same manner. PMID: 31930939 [PubMed - as supplied by publisher]

There is a substantial elevation in serum sLOX ‐1 levels after aSAH. There is an intimate correlation of serum sLOX‐1 levels with hemorrhagic severity. There is an independent association of serum sLOX‐1 levels with delayed cerebral ischemia. AbstractObjectiveDelayed cerebral ischemia (DCI) greatly contributes to the high morbidity and mortality of aneurysmal subarachnoid hemorrhage (aSAH) patients. Expression of lectin ‐like oxidized low‐density lipoprotein receptor‐1 (LOX‐1) was substantially raised in the basilar arterial wall of SAH rabbits. We attempted to ascertain the relationship between serum soluble...

Conclusions Our case report highlighting the clinical course and autopsy findings of a fatal SAH shortly after stenting this giant basilar artery aneurysm adds to the few previously reported fatal cases of IA rupture after endovascular treatment. Our macroscopic and histologic findings suggested that multimodal changes of inflammation, wall sheer tress (mechanical), and recanalization were involved.

AbstractBackgroundCritically ill aneurysmal subarachnoid hemorrhage (aSAH) patients suffer from systemic complications at a high rate. Hyperglycemia is a common intensive care unit (ICU) complication and has become a focus after aggressive glucose management was associated with improved ICU outcomes. Subsequent research has suggested that glucose variability, not a specific blood glucose range, may be a more appropriate clinical target. Glucose variability is highly correlated to poor outcomes in a wide spectrum of critically ill patients. Here, we investigate the changes between subsequent glucose values termed “int...

Background/objective: Subarachnoid hemorrhage (SAH) is a devastating neurologic event for which markers to assess poor outcome are needed. Elevated cerebrospinal fluid (CSF) protein may result from inflammation and blood-brain barrier (BBB) disruption that occurs during SAH. We sought to determine if CSF protein level is associated with functional outcome after SAH. Methods: We prospectively collected single-center demographic and clinical data for consecutive patients admitted with spontaneous SAH.

Abstract Human infection with the trematode Fasciola occurs with a worldwide prevalence of up to 17 million. Sheep and cattle are the normal host. Infection typically results in hepatobiliary disease, but extrahepatic manifestations are occasionally reported. Here, we present the case of a previously healthy 31-year-old Kurdish woman, admitted to hospital with a subarachnoid hemorrhage, eosinophilic meningitis, and lung and liver disease. A diagnosis of Fasciola infection was made based on strongly positive serology in blood and cerebrospinal fluid. The patient improved following treatment with triclabendazole and...
