BACKGROUND Angiopeptin, a synthetic somatostatin analogue, reduces myointimal hyperplasia after experimental balloon angioplasty when given subcutaneously. The feasibility and efficacy of a single dose of angiopeptin delivered locally via the Wolinsky porous balloon on myointimal hyperplasia were studied. METHODS AND RESULTS Three rabbits received 125I-angiopeptin in the mid abdominal aorta v...

A 14-year old male with no previous medical history presented with headache, left third cranial nerve palsy, and generalized tonic-clonic seizures. Magnetic resonance imaging of the brain revealed subarachnoid hemorrhage secondary to an aneurysm of the left posterior communicating artery. The patient underwent successful transcatheter coil occlusion of the aneurysm, and his neurological symptom...

PURPOSE We conducted a novel quantitative three-dimensional analysis of computed tomography (CT) angiograms to establish the relationship between aortic geometry and age, sex, and body surface area in healthy subjects. METHODS Abdominal helical CT angiograms from 77 healthy potential renal donors (33 men/44 women; mean age, 44 years; age range, 19-67 years) were selected. In each dataset, ort...

BACKGROUND Atherosclerosis begins in childhood and progresses through young adulthood to form the lesions that cause coronary heart disease. These preclinical lesions are associated with coronary heart disease risk factors in young persons. METHODS The Pathobiological Determinants of Atherosclerosis in Youth study collected arteries and samples of blood and other tissues from persons aged 15 ...

AIM To study the morphologic and cellular immunologic changes after homologous transplantation of the abdominal aorta in rats after programmed cryopreservation (-196 degrees). METHODS Abdominal aorta was harvested from anesthetized Spraque Dawley (SD) rats for cryopreservation (group B) or immediate implantation (group A). The survival rates and apoptotic rates of aortic endothelial cells (EC...

We report a case of concurrent saccular aneurysms caused by a penetrating atherosclerotic ulcer of the thoracic and abdominal aorta that were successfully treated by staged endovascular repair. Even though surgical open repair or endovascular repair is the treatment option, use of endovascular repair is now accepted as an alternative treatment to surgery in selected patients. To prevent contras...

The hemodynamic effects of closed-chest extracorporeal circulation were investigated in normal dogs and in dogs subjected to coronary embolization. In both groups, despite delivery of large volumes of blood into the abdominal aorta through peripheral routes, a rise in proximal aortic pressure could not be achieved; to accomplish this it was necessary to increase vascular resistance by balloon o...

We present a case of 71 year old man operated in our clinic for ruptured abdominal aneurysm complicated with aorto-caval fistula, which was revealed during the surgery and successfully repaired by direct sutures within the aorta. This is the first record of the aorto-caval fistula that was so far noticed in our clinic. Urgent surgery and repair of the defect conneting aorta and vena cava by dir...

Nutcracker syndrome is a rare condition that refers to compression of left renal vein (LRV) between abdominal aorta and superior mesenteric artery. The most common location of compression is between the superior mesenteric artery (SMA; Pic. 1) and abdominal aorta. The name derives from the fact that, in the sagittal plane and/or transverse plane, the SMA and aorta (with some imagination) appear...

Pulmonary sequestration (PS) is a rare congenital malformation. Right intra lobar PS with a feeding artery arising from the abdominal aorta is extremely rare. This case report describes a 30-year-old man with a history of mental deficiency and repeated pneumonia who was referred to our hospital for further work-up of PS. Three-dimensional enhanced computed tomography of the chest and aorta reve...
