introduction induction of general anesthesia in patients with superior vena cava (svc) syndrome may cause airway obstruction and cardiovascular collapse. case presentation herein, we introduced a patient with the diagnosis of dissecting aneurysm of the ascending aorta who was candidate for emergency surgery. he also had symptoms of svc syndrome. to maintain airway patency during anesthetic mana...

Although classic and standard procedure for patients with ascending Aorta aneurysm with Sever aortic Regurgitation is Bentall surgery but in some selected cases this complex surgery was not performed with different reason like advanced age and coexisting comorbidity involving renal and hepatic and lung Function. In our cases 75 years old man with chronic renal failure ( Cr= 3.2 ) who was known ...

BACKGROUND Coarctation of the aorta accounts for almost 5% of all congenital cardiac malformations, and it is usually treated by open surgical procedures. Despite the excellent primary results, many patients may develop anastomotic pseudo-aneurysms, associated with considerable morbidity and mortality rates. We investigated the role of endovascular repair as an alternative to open re-do surgery...

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...
