I wo-dimensional echocardiography has been used extensively to assess aortic arch anatomy in infants and children. Echocardiographic techniques for examination of left and right aortic arch, coarctation and interruption of the aorta, aortic aneurysm and double aortic arch have been well described.lp2 Right aortic arch with retroesophageal segment and left descending aorta, an unusual form of va...

BACKGROUND Deep hypothermic circulatory arrest (DHCA) without retrograde cerebral perfusion (RCP) has a strict time limit. We modified a surgical technique for anastomosis to shorten the period of DHCA and unilateral cerebral perfusion (UCP). METHODS Between March 1993 and August 2001, retrospective analysis was done on 23 consecutive patients, who underwent aortic arch replacement with branc...

We present the case of a 57-year-old woman who had an intramural hematoma of the ascending aorta and aortic arch. After initial blood pressure control and imaging studies, the patient underwent limited surgical repair that consisted of ascending aortic replacement. One week postoperatively, the aortic arch hematoma progressed to a full dissection that extended into the proximal descending aorta...

BACKGROUND The long-term effects of some surgical treatment procedures of arch replacement for aortic dissection or aortic aneurysm are unknown. CASE PRESENTATION The present study reports the case of a 68-year-old man admitted to our hospital for aortic arch anastomotic pseudoaneurysm with concomitant aortic root enlargement and coronary artery stenosis. Eleven years ago, at the age of 56 ye...

Transformation from the bilaterally symmetric embryonic aortic arches to the mature great vessels is a complex morphogenetic process, requiring both vasculogenic and angiogenic mechanisms. Early aortic arch development occurs simultaneously with rapid changes in pulsatile blood flow, ventricular function, and downstream impedance in both invertebrate and vertebrate species. These dynamic biomec...

We report the case of a 2-month-old baby with a double aortic arch, type C atresia of the left arch and severe hypoplasia of the right aortic arch between the right carotid and subclavian arteries, resulting in systemic obstruction, left ventricular dysfunction and congestive heart failure. Surgical augmentation of the right aortic arch ameliorated the obstruction with improvement in left ventr...

Aortic arch blunt injury has highly lethal nature. Because the physical examination findings are subtle, immediate medical evaluation is very important. The case was a 72-year-old woman. Massive haemorrhage in the left haemotorax, contusion area in the left lung and a traumatic transection of the distal aortic arch was observed during autopsy. We described intersting autopsy case of aortic arch...

RATIONALE Apolipoprotein E-null mice with a 129S6/SvEvTac strain background (129-apoE) develop atherosclerotic plaques faster in the aortic arch but slower in the aortic root than those with a C57BL/6J background (B6-apoE). The shape of the aortic arch also differs in the 2 strains. OBJECTIVE Because circulating plasma factors are the same at both locations, we tested the hypothesis that gene...

Aortic pseudocoarctation is a rare congenital anomaly characterized by elongation and deformity of the aortic arch and is known to be associated with aneurysmal formation. Several studies unite to say it leads to a surgical sanction as soon as symptomatic or associated with aneurysms of the aortic arch. Our patient is a 12 years old boy, followed since birth for a little tight pseudocoarctation...
