Abdominal aortic aneurysm (AAA) is a ballooning of the aorta, the largest blood vessel in the human body, which extends into the abdomen. If the wall of this blood vessel becomes weakened, it can stretch, "balloon" out and rupture. A rupture, if left untreated, can lead to life-threatening internal bleeding. The exact cause of this condition is unknown. However, it often occurs in older adults, especially males, those with a high cholesterol level, and in smokers. There also tends to be a genetic link to this disorder.
Some 10 million points of genetic variation are scattered across a molecule of DNA, and those variations make us who we are as individuals. But in some cases, those variants contribute to diseases, and it's a major challenge for scientists to distinguish between harmless variants and those that are potentially hazardous to our health.
A minimally-invasive procedure to fix a life-threatening condition may be associated with an increase in long-term complications, compared to an alternative procedure.
Mice placed on a low-calorie diet are less likely to develop abdominal aortic aneurysms, according to a new study in The Journal of Experimental Medicine.
On Super Bowl Sunday, Tina Wilkins was relaxing in her recliner while she chatted on the phone with her mother and waited for the game to begin. She had recently lost 63 pounds and was in better shape than she had been in years.
People with a family member who had an aortic dissection—a spontaneous tear in one of the body's main arteries—should take note of the age that family member was when the aortic dissection occurred.
Japan's favorite beverage might be offering more than just a relaxing tea break.
Aortic disease, including aortic aneurysm and aortic dissection, is an important cause of cardiovascular morbidity and death. There have been exciting developments in caring for patients with aortic aneurysm and dissection, including great advances in diagnosis and endovascular therapies.
New findings from large-scale studies of more than 3.6 million people who underwent screening for cardiovascular disease reveals that a person's age and gender affects the prevalence of certain types of peripheral vascular diseases (PVD), and that diabetes is a major risk factor for developing these diseases, even in patients without heart disease.
Acute mesenteric ischemia (AMI) can be successfully treated with endovascular therapy such as balloon angioplasty, according to research from the University of Eastern Finland. The study also found that AMI is a more common cause of abdominal pain among the elderly than generally thought; however, it is difficult to diagnose before bowel damage develops.
To improve access to high-quality, advanced cardiac surgery services in St. Petersburg and south Pinellas County, BayCare Health System has opened a BayCare Cardiovascular and Thoracic Surgery office at St. Anthony's Hospital.
A large new study reveals previously unknown risk factors associated with an eye condition that causes serious progressive nearsightedness at a relatively young age.
Considerable racial disparities exist in surgical outcomes for black and Hispanic patients undergoing major cancer and non-cancer surgeries in U.S. hospitals, even among institutions that have already enrolled in a national surgical quality improvement initiative.
Renal Dynamics' third-generation Renal Denervation System received CE clearance and is now commercially available in Europe for treatment of Resistant Hypertension. The ReDy Renal Denervation System is based on a novel multi-electrode ablation technology that delivers a pre-determined RF ablation set with a single positioning.
Rupture of an abdominal aortic aneurysm is one of the most dramatic medical emergencies a person can face. It usually strikes without warning, killing approximately 50 percent of those who experience it before they reach a hospital. Of those who do get to a health facility alive, only about 50 percent survive.
Virtual models can be created in the angiography room thanks to an approach developed by researchers at the University of Montreal Hospital Research Centre and the university's departments of radiology, radiation oncology, and nuclear medicine. The latest advances were presented by Dr. Gilles Soulez at the Cardiovascular and Interventional Radiology Society of Europe conference on September 27, 2015.
Acute Cardiovascular Care 2015 will highlight innovations and controversies in the field, guaranteeing great stories on topics relevant to the press.
Each year, nearly 40,000 Americans undergo elective surgery to repair an abdominal aortic aneurysm with the goal of preventing a life-threatening rupture of this potentially dangerous cardiovascular condition.
Researchers at the Aortic Institute at Yale have tested the genomes of more than 100 patients with thoracic aortic aneurysms, a potentially lethal condition, and provided genetically personalized care. Their work will also lead to the development of a "dictionary" of genes specific to the disease, according to researchers.
Men benefit from one-time screening for abdominal aortic aneurysms via ultrasound. Studies provide proof that their risk of dying is reduced, the abdominal aorta ruptures less often, and emergency surgery can be avoided more often. Far fewer data are available for women and they show no relevant differences between the groups investigated.
Thoracic aortic aneurysm and dissection (TAAD), an enlargement or tearing of the walls of the aorta in the chest, is, together with abdominal aortic aneurysms, responsible for about 2% of all deaths in Western countries. The aorta is the largest artery in the body, and carries blood from the heart. About one out of every five patients with TAAD has a family member with the same disorder, therefore indicating a genetic cause.
