    A simple post mortem room angiography method for the investigation of traumatic basal subarachnoid hemorrhage.
    Forensic Sci Med Pathol 2017 Mar 17;13(1):4-9. Epub 2017 Jan 17.
    Forensic Pathology Unit, Department of Pathology, Royal Liverpool University Hospital, Liverpool, L7 8XP, UK.
    Identifying the site of vascular bleeding in fatal cases of traumatic basal subarachnoid hemorrhage (TBSAH) is important, but can be very difficult to achieve when there is extensive blood clot in the posterior cranial fossa. Post mortem angiography in these circumstances has been reported previously but with mixed results, and is rarely used in current practice within the United Kingdom. We have developed a simple and effective post mortem angiography method, using fluoroscopy and clear modern contrast medium, suitable for use in the autopsy room. Read More

    Vertebral artery dissection with compelling evidence on duplex ultrasound presenting only with neck pain.
    Neuropsychiatr Dis Treat 2016 1;12:2839-2841. Epub 2016 Nov 1.
    Department of Neurology, Carl Gustav Carus University Hospital, Technische Universität Dresden, Dresden, Germany.
    Vertebral artery dissection (VAD) is among the most common identifiable etiologies of stroke in young adults and poses a diagnostic challenge due to nonspecific symptoms and substantial variability of imaging results. Here, we present a case of unspecific neck pain as isolated symptom of VAD with unusually compelling evidence on duplex ultrasound. This observation has clinical relevance as the absence of any neurological symptoms in our patient highlights the necessity of considering cervical artery dissection in patients presenting with unspecific symptoms such as neck pain, even if isolated.

    Does case misclassification threaten the validity of studies investigating the relationship between neck manipulation and vertebral artery dissection stroke? No.
    Chiropr Man Therap 2016 5;24:43. Epub 2016 Nov 5.
    University of Western States, 2900 NE 132nd Avenue, Portland, OR 97230 USA.
    Background: The purported relationship between cervical manipulative therapy (CMT) and stroke related to vertebral artery dissection (VAD) has been debated for several decades. A large number of publications, from case reports to case-control studies, have investigated this relationship. A recent article suggested that case misclassification in the case-control studies on this topic resulted in biased odds ratios in those studies. Read More

    Does case misclassification threaten the validity of studies investigating the relationship between neck manipulation and vertebral artery dissection stroke? Yes.
    Chiropr Man Therap 2016 5;24:42. Epub 2016 Nov 5.
    Predictive Analytics and Comparative Effectiveness (PACE) Center, Institute for Clinical Research and Health Policy Studies (ICRHPS), Tufts Medical Center/Tufts University School of Medicine, Boston, MA USA ; Department of Neurology, Tufts Medical Center/Tufts University School of Medicine, 800 Washington St, Box 314, Boston, MA 02111 USA.
    Background: For patients and health care providers who are considering spinal manipulative therapy of the neck, it is crucial to establish if it is a trigger for cervical artery dissection and/or stroke, and if it is, the magnitude of the risk.

    Discussion: We discuss the biological plausibility of how neck manipulation could cause cervical artery dissection. We also discuss how case misclassification threatens the validity of influential published studies that have investigated the relationship between neck manipulation and dissection. Read More

Here, we report a case of bilateral vertebral artery dissecting aneurysm presenting with subarachnoid haemorrhage that was treated with stent-assisted coiling for the ruptured side. Read More
