Access product information about the Pipeline Flex embolization device, which redefines treatment for large or giant wide-necked aneurysms by diverting flow away from the aneurysm neck and by reconstructing the parent artery and restoring its natural course.
Sep 12th, 2019 - A defect in serine metabolism was found to be behind a rare macular disease, according to researchers reporting a new connection between central and peripheral neuropathies. Genetic mutations in SPTLC1 and SPTLC2, known to cause hereditary sensory and autonomic neuropathy type 1 (HSAN1), were also tied to macular telangiectasia type 2 from exome sequencing, according to a report by Martin Fried...
Apr 8th, 2019 - Angiotensin II antagonists may help prevent GI bleeding among heart failure patients with continuous-flow left ventricular assist devices (LVADs), a retrospective study suggested. Taking ACE inhibitors or angiotensin receptor blockers (ARBs) at any point within the first 30 days following LVAD placement was associated with a reduced subsequent risk of major GI bleeds (15% vs 31%, adjusted HR 0....
Dec 5th, 2018 - Two companies now owned by Medtronic have agreed to pay a total of $31 million to resolve US Department of Justice (DOJ) charges involving marketing violations and kickback schemes. Medical device maker ev3 has agreed to plead guilty to charges related to its neurovascular medical device Onyx Liquid Embolic System and pay $17.9 million, the DOJ said. The US Food and Drug Administration (FDA) ap...
Oct 17th, 2018 - It is clear that high levels of total homocysteine (tHcy) are a strong, graded risk factor for vascular disease. This is particularly true for cardioembolic stroke; high levels of tHcy quadruple the risk of stroke in atrial fibrillation. Vitamin therapy with folic acid, B6, and B12 can lower levels of tHcy, so it was logical to think that they should reduce the risk of cardiovascular events. No...

Jan 10th, 2018 - The two most common gastrointestinal conditions reported by people living with HIV/AIDS are diarrhea and nausea, according to Vincent Hall, PhD. Diarrhea has been reported in up to 60% of people living with HIV/AIDS, and is generally classified as being infectious or noninfectious.
Jan 9th, 2018 - Researchers have identified a genetic mutation in patients with an arteriovenous malformation (AVM) of the brain, a leading cause of hemorrhagic stroke in young adults and children. Results of their new study suggest that these malformations are a result of KRAS-induced activation of the mitogen-activated protein kinase–extracellular signal-regulated kinase (MAPK-ERK) signaling pathway in brain...
Jan 4th, 2018 - Action Points Note that this observational study found a high rate of KRAS mutations in tissue samples of brain arteriovenous malformations. Be aware that these mutations were not detected in peripheral blood, suggesting they are acquired at some point during life. Arteriovenous malformations of the brain may arise due to a genetic mutation, acquired later in life, that activates a cellular sig...
Sep 14th, 2017 - New guidelines for the diagnosis and treatment of cerebral venous thrombosis (CVT) have been issued by the European Stroke Organisation. The guidelines, published in the European Journal of Neurology, have also been endorsed by the European Academy of Neurology. "There has been a lot of uncertainty about the best treatments for CVT and several therapies used are unproven with little safety dat...
Jul 14th, 2017 - The case discussed here illustrates the clinical presentation and diagnostic complexities of CVT. Two days before coming to the ED, the patient presented to an outside facility and underwent a workup for nonspecific symptoms (eg, confusion, headaches).

Jun 5th, 2017 - Small intracranial aneurysms have a low risk for growth and rupture, and very small aneurysms have an even lower risk, although the quality of the evidence is not ideal, results of a new systematic review suggest. "The evidence is poor, but we are making clinical decisions based on this very same evidence," lead author, Ajay Malhotra, MD, associate professor, Department of Radiology and Biomedi...
Nov 17th, 2016 - Cardiovascular autonomic neuropathy (CAN) is associated with cardiovascular events in type 1 diabetes, new research shows. The findings, from 1251 participants in the randomized Diabetes Control and Complications Trial (DCCT) and its observational follow-up Epidemiology of Diabetes Interventions and Complications (EDIC) study, were published online November 1 in Diabetes Care by Rodica Pop-Busu...
Jul 7th, 2016 - Recent studies have helped clarify the natural history risks of intracranial hemorrhage (ICH) and seizure in patients with unruptured brain arteriovenous malformations (AVMs). In addition, researchers have completed the first randomized trial of interventional therapy versus conservative management for unruptured brain AVMs.
Mar 15th, 2016 - Women who are obese and are taking oral contraceptives have a significantly increased risk for cerebral venous thrombosis (CVT), a new study suggests. The study, published online in JAMA Neurology on March 14, was conducted by a group led by Jonathan M. Coutinho, MD, Academic Medical Centre, Amsterdam, the Netherlands. He explained to Medscape Medical News that CVT is a severe disease — much mo...
Mar 15th, 2016 - Action Points Note that this observational study found that among overweight and obese women, the use of oral contraceptives was associated with increased risk of central venous thrombosis. Be aware that the overall absolute risk was quite low. Women who are overweight or obese and using oral contraceptives had a significantly increased risk of cerebral venous thrombosis (CVT) compared with wom...
Mar 14th, 2016 - NEW YORK (Reuters Health) - Obese women who take oral contraceptives face a markedly increased risk of cerebral venous thrombosis (CVT), according to results from a case-control study in the Netherlands and Switzerland. "Physicians should have a lower threshold of suspecting CVT in an obese woman who uses oral contraceptives if they present with symptoms such as severe headache, focal neurologi...
Mar 14th, 2016 - Obese women taking oral contraceptives had a 30-fold increased odds for cerebral venous thrombosis (CVT), compared with normal-weight women, in an unmatched case-control study of 186 CVT cases and 6,134 controls. The association between a body-mass index of 30 kg/m2 or higher and increased odds of CVT “appears to be fully attributable to a strongly increased risk in women who use oral contracep.
