We present the first mathematical model to account for the evolution of the abdominal aortic aneurysm. The artery is modelled as a two-layered, cylindrical membrane using nonlinear elasticity and a physiologically realistic constitutive model. It is subject to a constant systolic pressure and a physiological axial prestretch. The development of the aneurysm is assumed to be a consequence of the...

Although surgical repair of thoracic (TAA) and thoracoabdominal aortic aneurysms (TAAA) is an effective therapeutic option with excellent long-term results, with a number needed to treat of two, it is also a potentially problematic procedure, owing to both technical difficulties of aortic reconstruction and organ stress suffered in patients who are often elderly and afflicted by multiple comorb...

The not uncommon combination of ascending aortic pathology with late presenting coarctation is a difficult surgical challenge. The two stage approach is usually adopted. The necessity for cardiac transplantation adds to the complexity: a trans-sternal approach and single stage repair become mandatory.

Intestinal malrotation (IM) is an anomaly of fetal intestinal rotation that usually presents in the first month of life; it is rare for malrotaion to present in adulthood. Furthermore, the presentation of IM in conjunction with Abdominal aortic aneurysm is extremely rare and may require consideration with respect to the surgical approach and exposure of the abdominal aorta. We herein report a c...

background: coarctation of the aorta (coa) is a defect that accounts for 5-8% of all congenital heart diseases. balloon angioplasty as a treatment for coa is increasingly performed, with endovascular stents having been proposed as a means of improving the efficacy and safety of the procedure. the aim of this study was to evaluate the systolic blood pressure gradient at rest and during maximal e...

background: it is well known that the development of brain oxidative stress is one of the most serious complications of arterial hypertension that evokes brain tissue damage. the aim of this study was to examine the effects of atorvastatin treatment (20 mg/kg/day), as an antioxidant, to prevent the brain tissue oxidative stress in the hypertensive (htn) rats. methods: experiments were performed...

The aorta of a patient with aortic valve stenosis may be unduly thin, fragile, and liable to dissect irrespective of the presence or absence of atheroma. Indeed, Coleman (1955) stated that aortic dissection in young people was most commonly associated with coarctation or with bicuspid aortic valve. Petch (1952) reported fatal haemopericardium from ruptured dissecting aneurysm in a man of 35 yea...

BACKGROUND Coarctation of the aorta (CoA) with aortic arch hypoplasia (AAH) is a relatively common congenital heart disease in clinical practice. Nonetheless, the corrective surgical technique for infants and children is a clinical problem that remains controversial. In this study, we sought to evaluate the surgical effects of aortic arch (AA) reconstruction with coarctation resection and aorto...

Aortic coarctation is a congenital vascular lesion, usually diagnosed and corrected in childhood or early adulthood. Most of the untreated patients with aortic die before age 50 years. Coarctation cardiac lesions complex clinical situation that necessitates surgical treatment different pathologies strategies.
 In this, study we report two-staged severe stenosis consist valve replacement ao...

Four cases of simultaneous surgery for aortic root aneurysm with aortic regurgitation and coarctation of the aorta were presented. Age at surgery ranged from 18 to 37 years and all were male. All had annuloaortic ectasia and dilatation of the ascending aorta, 3 had bicuspid aortic valve and 1 had acute localized aortic dissection. Preoperative grade of aortic regurgitation was trivial in 1, mod...
