People who developed a type of aneurysm with a cervical artery dissection (a tear in the inner lining of the neck artery wall), a known cause of stroke, particularly in young adults, did not have an increased risk of stroke within the six months after diagnosis, according to a preliminary study presented at the American Stroke Association's International Stroke Conference 2026, held in New Orleans, Feb. 4–6, 2026. https://medicalxpress.com/news/2026-01-lining-neck-artery-months-diagnosis.html Thu, 29 Jan 2026 05:44:30 EST news688887841 Through a statewide partnership, hospitals in Michigan drastically increased the number of patients who receive follow-up imaging after undergoing aortic aneurysm repair, according to a recent study. https://medicalxpress.com/news/2026-01-hospital-partnership-scans-decreases-term.html Mon, 19 Jan 2026 08:22:23 EST news688033321 Older people with a history of chronic kidney disease or conditions affecting blood flow to the brain such as stroke face about double the risk of developing neuroinvasive disease that can lead to paralysis and death following infection with West Nile virus, new UCLA research finds. https://medicalxpress.com/news/2025-12-aging-population-escalating-west-nile.html Wed, 10 Dec 2025 11:00:02 EST news684583866 If you watched Kim Kardashian's latest health update and felt a jolt at the phrase "holes on the brain," you were not alone. It is a term that sounds catastrophic. Yet on the type of scan she had, a hole does not mean missing tissue. It signals a region working at a lower level because it is receiving less blood and oxygen, often due to age, stress or other long-term influences. That distinction matters. True holes look very different and usually arise from severe disease. https://medicalxpress.com/news/2025-12-stress-holes-regions-brain.html Mon, 08 Dec 2025 18:10:01 EST news684421145 Older adults who have a heart attack may be more likely to develop epilepsy later in life, according to a study published in Neurology. While the study shows a link between these conditions, it does not prove cause and effect. https://medicalxpress.com/news/2025-11-links-heart-late-onset-epilepsy.html Wed, 05 Nov 2025 16:00:01 EST news681555121 Endovascular aneurysm repair is a minimally invasive technique for the treatment of abdominal aortic aneurysms—life-threatening bulges in the aorta's abdominal section. However, it carries the risk of recurrence owing to endoleaks after stent graft implantation, necessitating regular follow-up, especially since these leaks cannot be easily linked to specific symptoms. https://medicalxpress.com/news/2025-10-sensor-endoleak.html Wed, 15 Oct 2025 14:31:04 EDT news679757462 Cleveland Clinic researchers have discovered a connection between elevated blood levels of TMAO (trimethylamine N-oxide)—a byproduct of gut bacteria digestion of nutrients found in red meat and other animal products—and a higher risk of abdominal aortic aneurysms. https://medicalxpress.com/news/2025-08-red-meat-gut-byproduct-linked.html Wed, 20 Aug 2025 11:00:12 EDT news674815831 High levels of triglycerides, the most common type of fat in the body and the foods we eat, directly cause abdominal aortic aneurysms, according to a study in mouse models led by Michigan Medicine. https://medicalxpress.com/news/2025-08-high-triglycerides-life-threatening-aortic.html Thu, 14 Aug 2025 09:54:52 EDT news674384090 To simulate blood flow inside brain aneurysms, researchers from Japan have developed a computational method that combines 4D flow MRI, computational fluid dynamics, and data assimilation, which provides greater accuracy and efficiency. By focusing only on the aneurysm region, this approach significantly reduces computational cost while improving flow estimation. When validated on patient data, it outperforms conventional models—offering a practical tool for patient-specific risk assessment and treatment strategies. https://medicalxpress.com/news/2025-07-smarter-simulation-blood-brain-aneurysms.html Fri, 11 Jul 2025 04:25:40 EDT news671426735 By creating artificial aging in mice, researchers at Lund University in Sweden have been able to track the formation of aneurysms in the walls of blood vessels. https://medicalxpress.com/news/2025-07-cell-pathway-shield-blood-vessels.html Wed, 02 Jul 2025 15:14:39 EDT news670688073 Using gene editing in a preclinical model, researchers at UT Southwestern Medical Center blocked the symptoms of a rare smooth muscle disease before they developed. Their findings, published in Circulation, could eventually lead to gene therapies for this and other genetic diseases affecting smooth muscle cells. https://medicalxpress.com/news/2025-06-gene-smooth-muscle-disease-preclinical.html Tue, 24 Jun 2025 10:04:04 EDT news669978242 The European Medicines Agency (EMA) has designated allopurinol as the first orphan drug for the treatment of Marfan syndrome, a rare connective tissue disease which has no cure to date. This disease causes an aortic aneurysm (an abnormal dilation of the aorta) and affects about 7 in 100,000 people in the European Union. Drugs known as orphan drugs are intended to treat such rare conditions that pharmaceutical companies need favorable conditions to market them. https://medicalxpress.com/news/2025-05-allopurinol-orphan-drug-marfan-syndrome.html Mon, 19 May 2025 16:54:04 EDT news666892441 Oxidative stress can occur when our cells are exposed to harmful molecules called "reactive oxygen species" over time. These reactive oxygen species can damage cells and are found in important disease states, such as high blood pressure and aortic aneurysms. Aortic aneurysms are balloon-like swellings of the body's largest artery and are often fatal when the aneurysm bursts. https://medicalxpress.com/news/2025-04-scientists-hypertension-aortic-aneurysms.html Wed, 30 Apr 2025 15:45:20 EDT news665246712 Each year, nearly half a million people worldwide die from brain aneurysms. In the U.S., an estimated 6.7 million people have an unruptured brain aneurysm, which means about one in 50 people might have one. https://medicalxpress.com/news/2025-04-brain-aneurysms.html Sun, 06 Apr 2025 09:30:03 EDT news662977454 Australian radio host Kyle Sandilands announced on air yesterday that he has a brain aneurysm and needs urgent brain surgery. https://medicalxpress.com/news/2025-02-brain-aneurysm.html Tue, 04 Feb 2025 11:10:10 EST news657889525 Studying the cells of people and genetically engineered mice, Johns Hopkins Medicine scientists say they have uncovered a potential reason why patients with Loeys-Dietz syndrome, an inherited connective tissue disorder, are especially prone to developing aneurysms at the root of the aorta, the major artery that carries blood away from the heart and to the rest of the body. https://medicalxpress.com/news/2024-12-scientists-probable-contributor-weakness-aorta.html Mon, 09 Dec 2024 16:54:55 EST news652985687 A little of what you fancy does you good… unless it's a fizzy drink. Scientists studying the impact of sugar on the risk of cardiovascular disease have found that eating too much added sugar increases your risk of stroke or aneurysm, but eating a few treats is associated with a lower risk of cardiovascular diseases. Meanwhile, drinking sweetened beverages raises your risk of stroke, heart failure, and atrial fibrillation. https://medicalxpress.com/news/2024-12-sugary-significantly-cardiovascular-disease-occasional.html Mon, 09 Dec 2024 00:00:01 EST news652631641 Researchers from King's College London, in collaboration with academics from Imperial College London, are exploring whether artificial intelligence (AI) can help doctors predict which brain aneurysms are likely to rupture—a life-threatening event that requires urgent treatment. https://medicalxpress.com/news/2024-11-systematic-ai-brain-aneurysms.html Mon, 25 Nov 2024 15:56:00 EST news651772557 The moment Kirsten Dorsey realized she would deliver her second child and have open-heart surgery on the same day, her heart raced and her breath quickened. https://medicalxpress.com/news/2024-11-woman-marfan-syndrome-emergency-section.html Wed, 06 Nov 2024 09:40:01 EST news650107906 Obstructive sleep apnea may be a risk factor for developing abdominal aortic aneurysms, according to researchers from the University of Missouri School of Medicine and NextGen Precision Health. "Chronic Intermittent Hypoxia Facilitates the Development of Angiotensin II-Induced Abdominal Aortic Aneurysm in Male Mice" was recently published in the Journal of Applied Physiology. https://medicalxpress.com/news/2024-09-obstructive-apnea-abdominal-aortic-aneurysms.html Wed, 25 Sep 2024 12:45:19 EDT news646487114 A group of researchers at the University of Kentucky have found a mechanism that would explain why men develop more aortic aneurysms than women. https://medicalxpress.com/news/2024-09-sex-specific-differences-aortic-aneurysms.html Mon, 23 Sep 2024 12:08:11 EDT news646312086 The aorta, one of the "great arteries," carries blood away from the heart to support circulation throughout the body. However, sometimes a tear in the lining of the aorta can occur, and while this is uncommon, it often requires immediate treatment. That's why it's important for people to be aware of common risk factors and symptoms. https://medicalxpress.com/news/2024-09-qa-aortic.html Thu, 19 Sep 2024 16:00:01 EDT news645980030 Among people who had aneurysms (weakened areas in brain blood vessels), the risk of developing a mental health condition was higher than among peers without an aneurysm. The highest risk was seen in patients younger than age 40, according to research published in Stroke. https://medicalxpress.com/news/2024-08-brain-aneurysm-anxiety-mental-health.html Mon, 26 Aug 2024 14:20:05 EDT news643900802 There is a potential connection between a diagnosis of certain gastrointestinal (GI) syndromes and the formation and rupture of intracranial (brain) aneurysms, according to research presented today at the Society of NeuroInterventional Surgery's (SNIS) 21st Annual Meeting. https://medicalxpress.com/news/2024-07-reveals-link-gastrointestinal-syndromes-brain.html Mon, 22 Jul 2024 15:56:02 EDT news640882561 Abdominal aortic aneurysms can be deadly, but they are often underdiagnosed and/or undertreated in women. To help address this disparity, researchers at UC Davis Health have harnessed powerful artificial intelligence (AI) software to show how these aneurysms can grow faster in women and may require more rigorous surveillance. The study was published in the Journal of Vascular Surgery. https://medicalxpress.com/news/2024-07-ai-faster-growth-abdominal-aortic.html Tue, 09 Jul 2024 17:05:03 EDT news639763501 A vascular dilatation in the aorta can be life-threatening if it bursts.
