OBJECTIVE During extracorporeal circulation design and orientation of aortic cannulae tips mainly determine flow pattern in the aortic arch and arch vessels which is the objective of this in vitro study, comparing single versus multiple stream cannulae. METHODS In an aortic arch glass model, jet streams of 21-24 French aortic cannulae which were inserted in the ascending aorta were directed a...

Cervical aortic arch is a very rare anomaly presented as a pulsatile mass on the neck and usually with symptoms of dysphagia, cough and hoarseness. Rarer than the cervical aortic arch, is the aneurysm formation and, despite the equal sex distribution of cervical aortic arch, aneurysm formation always occurs in young females with only nine cases reported. We report herein a 24-year-old woman, di...

Two cases ofpersistent leftfifth aortic archforming a congenital double lumen aortic arch have been confirmed at necropsy. In the first case, the diagnosis was suspected during life after aortography. An unusual vessel ran inferior and parallel to the aortic arch from the innominate artery to the left subclavian artery. It lay superior to the pulmonary artery. Both cases were associated with ot...

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 esophageal cancer in the lower thoracic esophagus. Chest computed tomography reveale...

Today, open surgery is considered the gold standard in treating the ascending aorta and the aortic arch. However, conventional surgical techniques for managing the aortic arch are invasive and frequently associated with a significant systemic inflammatory response syndrome and related complications. Therefore, patients with multiple comorbidities are often classified as high risk and are denied...

To investigate the contribution of cranial neural crest cells to the developing cardiovascular system in the chick embryo, cauterization of various regions of cranial neural crest was performed. Five regions may be distinguished, each of which contributes mesenchyme to pharyngeal (branchial) arches 1 through 4 and 6. Ablation of arch 3, 4, and 6 regions resulted in a high incidence of persisten...

The reflex cardiac and respiratory effects of stepwise pressure variations in the isolated aortic arch were determined in anesthetized dogs. Elevation of pressure in the aortic arch depressed respiratory movements, decreased heart rate in the unpaced heart, and diminished peak pressure in the paced, isovolumetric left ventricle preparation. The threshold for these reflex effects was an aortic a...

At echocardiography a dysmorphic neonate was found to have a hypoplastic mitral valve, left ventricle, and ascending aorta with interruption of the aortic arch between the left common carotid and the left subclavian arteries--the left subclavian artery arose from a normal sized left descending aorta. Cardiac catheterisation and subsequent necropsy confirmed this arrangement but also showed a to...

BACKGROUND We aimed to analyze the risk factors and prognosis of acute kidney injury (AKI) after aortic arch repair in type A aortic dissection. MATERIAL AND METHODS We included 155 patients undergoing arch repair surgery for type A aortic dissection from January 2009 to January 2014 in our hospital. Ninety-three patients underwent ascending aortic replacement combined with open placement of ...

OBJECTIVE To investigate the incidence of clinical problems related to a bicuspid valve (aortic stenosis and regurgitation) and the incidence of ascending aorta and aortic arch pathology in combination with coarctation repair. PATIENTS 124 adult patients after surgical correction of aortic coarctation were studied. The incidence of aortic valve, ascending aorta, and aortic arch pathology was ...
