Study involving virtual patients is as effective as traditional clinical trials

A study involving virtual rather than real patients was as effective as traditional clinical trials in evaluating a medical device used to treat brain aneurysms, according to new research.

Corticosteroids may effectively treat children who develop a serious disorder after COVID-19

Corticosteroids may be an effective treatment for children who develop a rare but serious condition after COVID-19 infection.

Wearable sensor shows link between blood pressure and intracranial pressure

Brazilian researchers have simultaneously demonstrated the mechanism linking high blood pressure to elevated intracranial pressure, validated a non-invasive intracranial pressure monitoring method, and proposed a treatment for high blood pressure that does not affect intracranial hypertension.

New filling method to treat cerebral aneurysms

Cerebral aneurysms are malformations caused by abnormalities on the walls of blood vessels in the brain. When these blood vessels rupture, about 30% of the sufferers die on the spot, giving these the rightful label of 'ticking bombs in the head'.

Low-profile thoracic aortic endograft minimizes complications, increases patient pool

Preliminary results of a clinical trial, presented today at the AATS 101st Annual Meeting, showed that a new, low-profile thoracic aortic endograft is safe and effective in the treatment of descending thoracic aortic aneurysm or penetrating atherosclerotic ulcer (PAU) diseases.

Study casts doubt on promotion of 'Heat not Burn' products as less harmful alternative to cigarettes

The impact on lung cells of Heat not Burn products--a hybrid between traditional cigarettes and electronic vaping devices--may be no less harmful than that of conventional cigarettes, suggest the findings of a small comparative study, published online in the journal Thorax.

Study shows decline in subarachnoid hemorrhage hospitalizations during COVID-19 pandemic

New research led by investigators from Boston Medical Center and Grady Memorial Hospital demonstrates the significant decline in hospitalizations for neurological emergencies during the COVID-19 pandemic.

Researchers explore 3D printing materials to print realistic aorta models

Personalized 3D printed models created from cardiac imaging data, mainly from cardiac CT images have been increasingly used in cardiovascular disease, primarily in the preoperative planning and simulation of complex surgical procedures, as well as medical education.

New model to better predict risk of abdominal aortic aneurysms

An abdominal aortic aneurysm (AAA) can be a ticking time bomb if undiscovered in time. However, researchers at the University of Pittsburgh are developing a new model to better predict at-risk patients. And the tools they are using apply mechanical testing to the human body - which is itself a complex machine.

Researchers find higher odds of hospital readmission after endovascular aneurysm repair

Ruptured abdominal aortic aneurysms (rAAA) are responsible for nearly 2% of all deaths in U.S. men over the age of 65.

Research shows immediate phase of blood vessel restructuring after aneurysm

Hitting a pothole on the road in just the wrong way might create a bulge on the tire, a weakened spot that will almost certainly lead to an eventual flat tire. But what if that tire could immediately begin reknitting its rubber, reinforcing the bulge and preventing it from bursting?

Study reveals genetic abnormalities that cause brain aneurysms

Nearly three percent of the world's population is at risk of developing an intracranial aneurysm, a localized dilation of a blood vessel forming a fragile pocket. Rupture of this aneurysm results in extremely severe, and, in one-third of cases, fatal hemorrhage.

Steroids used to treat inflammatory disease increases risk of cardiovascular disease

Researchers have found that prescribed low doses of steroids, often to combat inflammatory diseases, are at an increased risk of cardiovascular diseases.

Study: Two common methods used to protect the brain during aortic aneurysm repair are equally effective

Two commonly used approaches to protect the brain during surgery to repair an ascending aortic aneurysm are equally effective, according to a review by University of Miami Miller School of Medicine researchers published October 6 in the Journal of Cardiac Surgery.

Researchers provide unique experiment for creating artificial tissue-engineered vascular graft

Researchers from St. Petersburg provided a unique experiment. They implanted a polymer scaffold as a vascular prosthesis into the rat abdominal aorta and monitored the process of its bioresobtion for 16 months. An artificial vessel was formed where the scaffold was located.

Study identifies genes linked with abdominal aortic aneurysm

A veteran's study identified more than a dozen genes associated with abdominal aortic aneurysm (AAA) that could be used to better identify people at risk for the often-deadly condition, according to new research published today in the American Heart Association's flagship journal Circulation.

MIS-C linked to COVID-19 damages children's hearts

Multisystem inflammatory syndrome in children (MIS-C), believed to be linked to COVID-19, damages the heart to such an extent that some children will need lifelong monitoring and interventions, said the senior author of a medical literature review published Sept. 4 in EClinicalMedicine, a journal of The Lancet.

Scientists combine 3D bioprinting and computer modeling to study cancer metastasis in blood vessels

Lawrence Livermore National Laboratory scientists have paired 3D-printed, living human brain vasculature with advanced computational flow simulations to better understand tumor cell attachment to blood vessels, the first step in secondary tumor formation during cancer metastasis.

Treatment of unruptured intracranial aneurysms substantially reduces mortality rates

Mortality rates after treatment of unruptured intracranial aneurysms have substantially decreased in the past decade, according to new findings presented today at the Society of NeuroInterventional Surgery's (SNIS) 17th Annual Meeting.
