For a 75 year-old man with extensive aortic aneurysm, who had undergone a previous infra-renal abdominal Y-graft, a staged replacement of remaining segments was performed. A hybrid procedure of open-laparotomy debranching of visceral branches and endovascular stentgraft insertion in the thoracoabdominal aorta was performed first, followed by subsequent direct replacement between the proximal as...

Few cases have been reported of the combination of right aortic arch with isolation of the left subclavian artery in childhood because of the absence of symptoms from this pairing of defects and the difficulty of its recognition by routine examination. All the reports have been associated with congenital heart disease. We report 4 cases. In one of them, the diagnosis was made during an attempt ...

Open repair of aneurysms and dissections involving the aortic arch has traditionally been associated with high rates of morbidity and mortality, primarily because of the complications related to the need to interrupt normal blood flow to the cerebral circulation. Over the past several years, our approach to these operations has gradually changed largely through the introduction of various techn...

We present a rare variation of the right-sided aortic arch with the retroesophageal left subclavian artery as the forth branch found in a cadaver of an 89-year-old Korean woman during a routine dissection. In this case, the first branch that arose from the ascending aorta was the left common carotid artery, which crossed ventral to the trachea in a left cephalic direction, followed by the right...

Introduction Congenital variations of the aortic arch and its branches are commonly encountered in radiological practice [13]. A right-sided aortic arch (RAA) with an aberrant left subclavian artery (ALSA) is a rare variation that occurs in 0.05% of the population. The most common vertebral artery variation is the left vertebral artery (LVA) arising from the aortic arch with a reported prevelan...

introduction: the persian squirrel (sciurus anomalus) is the only member of the sciuridae family found in the middle east. some people maintain them as pets, thus their referrals to veterinary hospitals has been increased recently. several morphological studies have been carried out mainly on the arch of aorta and its branches in common rodents, small mammals, and domestic animals but there are...

mobile luminal mass of aortic arch is an unusual finding in patients with peripheral embolization. to search the source of these emboli, aortic arch mass should be considered. to our knowledge, transesophageal echocardiography (tee) can be a useful modality to demonstrate the nature and exact location of the mass. this report is illustrative of a large mobile aortic arch mass, histologically th...

The frozen elephant trunk (FET) technique is a modification of the traditional elephant trunk method, which was introduced by Borst in 1983 in order to treat extensive thoracic aortic aneurysms. The crux of the new method is the different type of aortic prosthesis, consisting of a Dacron part (with or without branches leading to the arterial vessels which exit the aortic arch) and a port for ex...

It has been proposed that a mass transfer phenomenon called concentration polarization of low-density lipoproteins (LDLs) may occur in the arterial system and is likely involved in the localization of atherogenesis. To test the hypothesis that concentration polarization of LDL may be suppressed by the helical flow pattern in the human aorta, hence sparing the ascending aorta from atherosclerosi...
