over the last 50 years, significant progress has been made in the surgical repair of thoracoabdominal aortic aneurysms (taaa). improvements in perioperative care and surgical techniques have resulted in reductions in complication and mortality rates. adjunctive use of distal aortic perfusion and cerebrospinal fluid drainage has been especially helpful, reducing the incidence of neurological d...

Abdominal Aortic Aneurysms Human Studies The incidence of abdominal aortic aneurysms (AAA) is increasing in the elder population. Independent risk factors for AAA include not only aging but also male and smoking, whereas some risk factors such as hypertension and hypercholesterolemia have not been consistently demonstrated to be independent risk factors.

متن کاملAortic aneurysms and atherosclerosis.
T his issue of Circulation has an interesting contribution from Reed et al,' who advance the point of view that aortic aneurysms (AAs) are "caused" by atherosclerosis. Although some might believe that this conventional wisdom needs no defense, a dissenting perspective has grown from small beginnings in the late 1970s. Martin was among the first to question whether "dilating" disease of the aort...
متن کاملDeath of smooth muscle cells and expression of mediators of apoptosis by T lymphocytes in human abdominal aortic aneurysms.
BACKGROUND Thinning of the tunica media and rarefaction of smooth muscle cells (SMCs) characterize aneurysmal aortas. Apoptosis determines the cellularity and morphogenesis of tissue. Macrophages and T lymphocytes infiltrate the wall of abdominal aortic aneurysms (AAAs) and produce death-promoting proteins (perforin, Fas, and FasL). This study investigated whether apoptosis occurs in associatio...
متن کاملAortic valve and aneurysms.
The aorta is the highway in the human circulation, and accordingly any functional or structural change is associated with severe symptoms or even a fatal outcome. The aortic valve is the door to the aorta and it opens up to 3 billion times in a lifetime. If not perfectly built by nature, e.g. in biscuspid valve disease or tricuspid valves with raphe, aortic sclerosis and eventually stenosis are...
