A floating thrombus in an apparently normal aortic arch is a rare and often neglected source for systemic embolic events. When no other underlying pathology for systemic embolization can be found, transesophageal echo (TEE) and magnetic resonance imaging (MRI) are the diagnostic methods of choice and should be performed in ...

OBJECTIVE: Primary repair of aortic arch obstructions and associated cardiac anomalies is a surgical challenge in neonates and infants. Deep hypothermic circulatory arrest prolongs myocardial ischemia and might induce cerebral and myocardial dysfunction. METHODS: From March 2000 to December 2005, 69 neonates or infants with aortic arch anomaly underwent one-stage ...

The combination of hypoplastic left heart syndrome and a right-sided aortic arch is extremely rare and lethal. To the best of our knowledge, no patient with this combination has previously been reported as surviving initial palliation. The anatomic variant is associated with abnormalities in the arteries branching from the aortic ...

AIM: The standard approach for treating acute Type A aortic dissections (TAD) is replacement of the ascending aorta utilizing hypothermic circulatory arrest (HCA), which is associated with significant morbidity and frequently leaves a residual aortic arch dissection. We describe a staged surgical and endovascular technique of ascending aorta replacement and ...

Mice are widely used to study arterial disease in humans, and the pathogenesis of arterial diseases is known to be strongly influenced by hemodynamic factors. It is, therefore, of interest to characterize the hemodynamic environment in the mouse arterial tree. Previous measurements have suggested that many relevant hemodynamic variables are ...

Right aortic arch is a rare congenital vascular anomaly, thus, the surgical resection of esophageal cancer in a patient with this anomaly is extremely uncommon. The surgical treatment of esophageal cancer was performed in a 73-year-old man with right aortic arch. An upper GI series and endoscopy revealed Type 2 ...

Traditional repair of aortic arch aneurysms requires cardiopulmonary bypass, hypothermia, and circulatory arrest and is associated with considerable morbidity and mortality. Endovascular stent-graft placement has developed as a safe and effective treatment for various diseases of the descending aorta and, recently, even in delicate anatomic regions such as the aortic ...

Right aortic arch with an aberrant left innominate artery is a rare combination. We report a unique case of coarctation of the aorta in a patient with right aortic arch and aberrant left innominate artery. The diverticulum of Kommerell gave rise to the left innominate artery and a left ligamentum ...

Aortic valve diseases, hypertension, and connective tissue disorders may be causes of ascending aortic aneurysms. Aortic enlargement monitoring is essential for surgical timing and for operative design. In this regard, several imaging techniques may have limitations: magnetic resonance is not widespread and is expensive, computed tomography uses radiation, and transesophageal ...

The term "bovine arch" is widely used to describe a common anatomic variant of the human aortic arch branching. This so-called bovine aortic arch has no resemblance to the bovine aortic arch. We describe the most common human aortic arch branching patterns and compare these with the bovine aortic arch.

An adult male underwent chest radiography for a health check-up. This disclosed both thoracic vascular anomalies and a small nodular shadow in the left side of the superior mediastinum. Axial MRI and three-dimensional volume-rendering MR angiography revealed both a double aortic arch with left atretic arch proximal to the left ...
Tannous Henry J - - 2006
We present a case of type B interrupted aortic arch and aortic atresia. This combination is usually incompatible with life. However, the presence of an aberrant right subclavian artery and enough blood flow through the circle of Willis allowed perfusion of the coronary arteries through retrograde carotid and aortic blood ...
Caceres Manuel - - 2006
OBJECTIVE: Acyanotic congenital heart diseases may occasionally present with tracheobronchial obstruction. Increased pulmonary blood flow against a high-resistance pulmonary bed may create significant pulmonary artery dilation. METHODS: We report an unusual case of ventricular septal defect and right aortic arch coarctation, complicated with distal tracheal compression secondary to a pincer ...

HYPOTHESIS: Endovascular interventions have revolutionized the contemporary treatment of peripheral vascular occlusive disease. Traditional management of supra-aortic trunk disease has employed surgical extra-anatomic bypass via a cervical approach or median sternotomy. Endoluminal therapy may be a less morbid alternative. DESIGN AND SETTING: A retrospective review of procedures performed by vascular ...

Chahwan Santiago - - 2006
We present a patient with a rare anomaly of the aortic arch. Angiography revealed an aberrant right subclavian artery (aRSA) originating from the middle of the aortic arch. Angiography also demonstrated an anomalous origin of the left common carotid artery sharing a common trunk with the innominate artery and a ...
Kubota Hiroshi - - 2006
The surgical approach to the treatment of distal aortic arch aneurysms is still a matter of controversy. Median sternotomy is usually selected when the patient has the pulmonary emphysema, and the atherosclerotic change involves the ascending aorta or the aortic arch as well as the distal aortic arch. However, when ...
Panos Aristotelis - - 2006
BACKGROUND: Aortic arch surgery is still associated with increased mortality and morbidity especially in acute type A aortic dissection. Adequate brain protection is essential and commonly performed by either antegrade selective perfusion of the brachiocephalic arteries or an interval of profound hypothermic circulatory arrest. We present our experience for open ...

Right-sided aortic arch with a concomitant coarctation is an exceedingly rare congenital cardiac anomaly. We report of a 4-year-old boy who presented with a history of a stenotic bicuspid aortic valve who upon further evaluation was found to have a coarctation of a right-sided aortic arch. The frequency with which ...

The objective of this study was to determine if distortion of the left subclavian artery course distinguishes double aortic arch with atretic left dorsal aorta from right aortic arch with mirror image branching. We performed a retrospective case series at a tertiary care center. Twenty-six patients undergoing magnetic resonance imaging ...
Kobayashi N - - 2006
An anomalous branch of the right coronary artery was found in a 71-year-old male cadaver with a right-sided aortic arch. The anomalous artery arose from the proximal portion of the right coronary artery and ran in a retroaortic course, before reaching the posterior wall of the heart. It was recognized ...

OBJECTIVES: Can aortic isthmus disruption occurring in a lateral motor vehicle crash (LMVC) be explained by the Archimedes Lever Hypothesis, where the intrathoracic aorta, super-pressurized by the thoracic impact force, functions as a rigid lever system? The long arm of this lever system is the proximal aorta-aortic arch, the short ...

BACKGROUND: Surgical treatment for distal arch aneurysm carries the risk of stroke. Although left thoracotomy has been used for repair of distal arch aneurysm as a standard approach, we have performed total arch replacement under deep hypothermia with circulatory arrest through a midsternotomy for this subset of aneurysms. METHODS: From ...

Cardiovascular syphilis, which used to be a well-recognized manifestation of tertiary syphilis, has become a rarity. In this report we describe a 47-year-old man presenting with an aneurysm of the distal arch and proximal descending aorta, a somewhat unusual presentation for a syphilitic aneurysm, and discuss the clinical features of ...
Augustin Norbert - - 2006
A 59-year-old man showed a saccular aneurysm due to a penetrating atherosclerotic ulcer, as well as a small type B aortic dissection located in the proximal descending aorta. The lesion was treated by the implantation of a stent-graft. On release, the stent-graft dislocated into the aortic arch. Intraoperative angiogram showed ...
