Introduction Autopsy data has demonstrated that the abdominal aorta offers a valuable early window for the study of atherosclerosis. Current MRI strategies often suffer from long scan times or require slice gaps. We sought to implement a small field-of-view approach (zoom imaging) (Buecker, A. et al, 1998), to allow complete coverage of the thoracic and abdominal aorta. To improve blood signal ...

To investigate the effects of a tissue inhibitor of the matrix metalloproteinase-2 (TIMP-2) gene on the extracellular matrix of the abdominal aorta, models of rat abdominal aortic aneurysm were utilized and a solution of AdTIMP-2 was perfused into the abdominal aorta. The models of rat abdominal aortic aneurysm were constructed with intraluminal perfusion of the abdominal aorta with porcine pan...

Objective: Despite major advances in imaging techniques, correct diagnosis of acute aortic dissection is frequently missed. Although as many as one-third of acute cases of aortic dissection involve the abdominal aorta, emergency physicians rarely suspect this lethal disease in patients presenting with abdominal pain. Transabdominal sonography is typically employed by emergency physicians, but t...

BACKGROUND We designed this study to expand the usage of ultrasound to detect early occurrence of hypovolemia. We explore the potential use of inferior vena cava (IVC) and abdominal aorta (AA) diameter index (IVC:AA) measured ultrasonographically to detect class 1 hypovolemic shock with blood loss less than 15%.ᅟ METHODS The aim of this study was to determine the changes in the diameter of in...

Background The best treatment of abdominal aorta aneurysms of the segments below the emergency of the renal arteries are still under discussion. In literature there are several studies that compare the retroperitoneal (R.P.) approach with the transperitoneal (T.P.) one or that suggest their possible variations. The R.P. approach offers the possibility of treating patients with hostyle abdomen (...

The author has published this monograph, originally written as a dissertation for the M.D., partly at any rate at Professor Osier's suggestion. It consists of a careful analysis of thirtytwo cases, the clinical and pathological notes of which were found in the records of St. George's Hospital; and though little is unearthed that has not been taught before, yet the book is of much value in sever...

Traumatic pseudoaneurysm of the abdominal aorta is a life threatening and a rare condition in aortic injuries. Most lesions are caused by a penetrating injury and may not be detected during the first evaluation. The time interval from initial trauma to appearance of clinical signs and symptoms may range from a few days to many years, and there are only a few reports of delayed presentation. We ...

Objective(s): Cardiovascular disease is a leading cause of morbimortality with over half cardiovascular events occurring in the asymptomatic population by traditional risk stratification. This preliminary study aimed to evaluate systemic plaque vulnerability in patients with prior Coronary Artery Disease (CAD) with a single Whole Body [FDG] PET-CT scan in terms of plaq...

case presentation the current report presented an eight-year-old girl with microscopic hematuria and chronic abdominal pain along with short review of anatomy, pathophysiology, clinical significance and management of this syndrome. conclusions the nutcracker syndrome should be differentiated from unexplained chronic abdominal pain. introduction renal vein entrapment, named nutcracker phenomenon...

Perivascular adipose tissue (PVAT) is implicated as a source of proatherogenic cytokines. Phenotypic differences in local PVAT depots may contribute to differences in disease susceptibility among arteries and even regions within an artery. It has been proposed that PVAT around the abdominal and thoracic aorta shares characteristics of white and brown adipose tissue (BAT), respectively; however,...
