The "seagull cry" in a patient with a cerebral arteriovenous malformation.

ABSTRACT:

Introduction

The "seagull cry" is an acoustic phenomenon heard during duplex ultrasound. It is caused by harmonic covibrations of a vessel wall in the presence of high-velocity blood flow. It has been reported in a few cases of cerebrovascular disease, such as severe intracranial stenosis, vasospasm or carotid-cavernous fistula.

Material and methods

A 35-year-old man underwent transcranial color-coded sonography (TCCS) for work-up of a severe new-onset headache.

Results

Doppler spectral analysis of the right intracranial carotid bifurcation revealed multiple pairs of mirror-image parallel strings, and a high-frequency seagull cry was heard. Computed tomography-angiography and magnetic resonance imaging of the brain showed an arteriovenous malformation in the right temporal lobe.

Discussion

The seagull cry is a "musical murmur" with single or multiple frequency that sounds like a musical tone. This is the first report of this phenomenon in a cerebral arteriovenous malformation.

Patient-Specific Blood Flow Analysis for Cerebral Arteriovenous Malformation Based on Digital Subtraction Angiography Images.

Project description:Real-time digital subtraction angiography (DSA) is capable of revealing the cerebral vascular morphology and blood flow perfusion patterns of arterial venous malformations (AVMs). In this study, we analyze the DSA images of a subject-specific left posterior AVM case and customize a generic electric analog model for cerebral circulation accordingly. The generic model consists of electronic components representing 49 major cerebral arteries and veins, and yields their blood pressure and flow rate profiles. The model was adapted by incorporating the supplying and draining patterns of the AVM to simulate some typical AVM features such as the blood "steal" syndrome, where the flow rate in the left posterior artery increases by almost three times (∼300 ml/min vs 100 ml/min) compared with the healthy case. Meanwhile, the flow rate to the right posterior artery is reduced to ∼30 ml/min from 100 ml/min despite the presence of an autoregulation mechanism in the model. In addition, the blood pressure in the draining veins is increased from 9 to 22 mmHg, and the blood pressure in the feeding arteries is reduced from 85 to 30 mmHg due to the fistula effects of the AVM. In summary, a first DSA-based AVM model has been developed. More subject-specific AVM cases are required to apply the presented in silico model, and in vivo data are used to validate the simulation results.

Characterization of Endothelial Cells Associated with Cerebral Arteriovenous Malformation.

Project description:Introduction:Cerebral arteriovenous malformation (cAVM) is a disease characterized by the angiogenesis and remodeling of veins. However, whether vascular endothelial cells (ECs) exhibit morphological and functional changes during cAVM remains unclear. This study aimed to investigate the role of ECs in the pathogenesis of cAVM. Methods:Rat model of cAVM was established by anastomosing the common carotid artery with the external jugular vein. The digital subtraction angiography (DSA), HE, Masson and immunohistochemical staining were performed to evaluate the model. ECs were isolated from AVM rat model or control rats, and characterized by MTT, cell scratch, and tube formation assays. The secretion of vascular endothelial growth factor (VEGF) was detected by ELISA. Results:AVM rat model showed typical pathological characteristics of cAVM. In addition, the proliferation, migration and tube formation abilities of ECs of arterialized vein (AV-ECs) were significantly better than those of ECs of normal vein (NV-ECs). Moreover, the levels of secreted VEGF were significantly higher in AV-ECs than in NV-ECs. Conclusion:AV-ECs isolated from AVM rat model showed increased proliferation, migration and angiogenesis and may be potential target for the treatment of cAVM.

Computer simulation of Cerebral Arteriovenous Malformation-validation analysis of hemodynamics parameters.

Project description:ProblemThe purpose of this work is to provide some validation methods for evaluating the hemodynamic assessment of Cerebral Arteriovenous Malformation (CAVM). This article emphasizes the importance of validating noninvasive measurements for CAVM patients, which are designed using lumped models for complex vessel structure.MethodsThe validation of the hemodynamics assessment is based on invasive clinical measurements and cross-validation techniques with the Philips proprietary validated software's Qflow and 2D Perfursion.ResultsThe modeling results are validated for 30 CAVM patients for 150 vessel locations. Mean flow, diameter, and pressure were compared between modeling results and with clinical/cross validation measurements, using an independent two-tailed Student t test. Exponential regression analysis was used to assess the relationship between blood flow, vessel diameter, and pressure between them. Univariate analysis is used to assess the relationship between vessel diameter, vessel cross-sectional area, AVM volume, AVM pressure, and AVM flow results were performed with linear or exponential regression.DiscussionModeling results were compared with clinical measurements from vessel locations of cerebral regions. Also, the model is cross validated with Philips proprietary validated software's Qflow and 2D Perfursion. Our results shows that modeling results and clinical results are nearly matching with a small deviation.ConclusionIn this article, we have validated our modeling results with clinical measurements. The new approach for cross-validation is proposed by demonstrating the accuracy of our results with a validated product in a clinical environment.

BMP signaling modulation attenuates cerebral arteriovenous malformation formation in a vertebrate model.

Project description:Cerebral arteriovenous malformations (AVMs) are vascular anomalies that carry a high risk of stroke and death. To test potential AVM therapies, a reverse genetics approach was used to model AVMs in zebrafish. Antisense morpholino oligonucleotides were used to knockdown activin receptor-like kinase I (alk1), which encodes a transforming growth factor (TGF)-beta family type I receptor implicated in a subset of human AVMs. Knockdown of alk1 caused a spectrum of morphologic, functional, and molecular defects that resemble those seen in humans with AVMs. It was found that losartan, an angiotensin II receptor antagonist, attenuated abnormal blood vessel morphology and systemic manifestations of high-output arteriovenous shunting in vivo. SMAD1 phosphorylation was significantly decreased in alk1 morphants compared with uninjected organisms (0.189±0.0201, 0.429±0.0164, P=0.0002). After treatment, morphant SMAD1 levels approached uninjected levels (0.326±0.0360, P=0.0355) and were significantly higher than those seen in the morphant-control group (P=0.0294). These data suggest that modulating the BMP signaling pathway with losartan, a drug in widespread clinical use in humans as an antihypertensive, may have the potential to be further evaluated as a therapeutic strategy for patients with AVMs.

Untreated brain arteriovenous malformation: patient-level meta-analysis of hemorrhage predictors.

Project description:ObjectiveTo identify risk factors for intracranial hemorrhage in the natural history course of brain arteriovenous malformations (AVMs) using individual patient data meta-analysis of 4 existing cohorts.MethodsWe harmonized data from Kaiser Permanente of Northern California (n = 856), University of California San Francisco (n = 787), Columbia University (n = 672), and the Scottish Intracranial Vascular Malformation Study (n = 210). We censored patients at first treatment, death, last visit, or 10-year follow-up, and performed stratified Cox regression analysis of time-to-hemorrhage after evaluating hemorrhagic presentation, sex, age at diagnosis, deep venous drainage, and AVM size as predictors. Multiple imputation was performed to assess impact of missing data.ResultsA total of 141 hemorrhage events occurred during 6,074 patient-years of follow-up (annual rate of 2.3%, 95% confidence interval [CI] 2.0%-2.7%), higher for ruptured (4.8%, 3.9%-5.9%) than unruptured (1.3%, 1.0%-1.7%) AVMs at presentation. Hemorrhagic presentation (hazard ratio 3.86, 95% CI 2.42-6.14) and increasing age (1.34 per decade, 1.17-1.53) independently predicted hemorrhage and remained significant predictors in the imputed dataset. Female sex (1.49, 95% CI 0.96-2.30) and exclusively deep venous drainage (1.60, 0.95-2.68, p = 0.02 in imputed dataset) may be additional predictors. AVM size was not associated with intracerebral hemorrhage in multivariable models (p > 0.5).ConclusionThis large, individual patient data meta-analysis identified hemorrhagic presentation and increasing age as independent predictors of hemorrhage during follow-up. Additional AVM cohort data may further improve precision of estimates, identify new risk factors, and allow validation of prediction models.
