Manipulation of aorta, such as side clamping of the ascending aorta, is known as a possible cause of the increased incidence of perioperative cerebrovascular accidents during myocardial revascularization. We describe an easy and cheap alternative technique for proximal anastomosis of saphenous vein to aorta using a Hegar dilator without clamping in off-pump coronary artery bypass procedures. IN...

The Chinese alligator (Alligator sinensis) belongs to the genus Alligator, which is a unique crocodile in China. In order study macroscopic structure of heart alligator, we performed detailed cardiac anatomy on five specimens. cranial mediastinum. It caudally involved by liver margins, and ventrally ribs, intercostal muscles, sternum dorsally lungs. wild typical four-chamber heart, with two (ri...

The recent developments in computational fluid dynamics (CFD) can be useful observing the detailed haemodynamics renal artery bifurcation for clinical evaluation and treatment. present study focuses on haemodynamic behaviour of blood as it flows through abdominal aorta-renal junction an idealistic healthy with varying angles to aorta, i.e. from 30° 90° increments 15°. This is examine effect ang...

A 66-year-old man was admitted to our institute because of chest pain. He had undergone replacement of the ascending aorta due to aortic dissection 9 years previously. We made a diagnosis of acute coronary syndrome, and coronary artery angiography was performed. Although the right coronary artery was successfully cannulated, a severe bend of the artificial aorta made it very difficult to advanc...

During embryonic life, events may alter the normal growth and fusion of the endocardial tube, the paired dorsal aortae, and the vitelline plexus, leading to anomalies and variants of the mature axial arterial system.1 Many of these are well known, especially those associated with the aorta, heart, and umbilical artery.1,2 Vitelline variants have also been found that are either associated with M...

The Sun's procedure is a surgical technique proposed by Dr. Li-Zhong Sun in 2002 that integrates total aortic arch replacement using a tetrafurcated graft with implantation of a specially designed frozen elephant trunk (Cronus(®)) in the descending aorta. It is used as a treatment option for extensive aortic dissections or aneurysms involving the ascending aorta, aortic arch and the descending ...

Among the cyanotic congenital heart malformations, there is a group characterized anatomically by the presence of an atretic pulmonary artery and a biventricular aorta which acts as the only functioning vessel arising from the heart. A mixture of oxygenated blood from the left ventricle and unsaturated blood from the right ventricle is injected into the aorta, and the pulmonary vessels are fill...

Introduction: The Persian squirrel (Sciurus anomalus) is considered the only well-known species of the family Sciuridae in the Middle East. Since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. So far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. Hence, this research was performed to fil...

Internal thoracic and inferior thyroid arteries mainly supply the thymus. However, very few studies have been reported on the arterial variations of the thymus. The first author, a cardiac surgeon, happened upon a thymic artery arising from either proximal aortic arch or distal ascending aorta in a few cases during routine cardiac surgery in infants and neonates. Hence a study on the prevalence...

OBJECTIVES We present our experience of total aortic arch replacement. METHODS Twenty-nine patients (21 males and 8 females; mean age 63.3 ± 13.3 years) with extended thoracic aortic aneurysms underwent graft replacement. The pathology of the diseased aorta was non-dissecting aneurysm in 11 patients, including one aortitis and aortic dissection in 18 patients (acute type A: one, chronic type ...
