In anatomy, normality embraces a range of morphologies. It includes those that are more common and others called variations which are less frequent but not considered abnormal [1]. Arterial derangements within the thorax are common, complex and can assume many diverse forms. These derangements in origin and course of main vessels occurring either individually or in combination with other cardio...

Introduction: Arterial tortuosity syndrome (ATS), an autosomal recessive rare connective tissue disorder characterized by tortuosity, elongation and stenosis in the large and medium sized arteries. It manifestations include vascular and nonvascular connective tissue related symptoms. In this literature we describe the first cases of ATS from Iran. Case report: A six-months-old female wa...

a strategy employing moderate hypothermia for the replacement of the aortic arch is proposed to avoid the complications of profound hypothermic circulatory arrest. two patients underwent the complete replacement of the aortic arch using three pumps - for the brain, thoracoabdominal aorta, and heart, respectively. there were no complications and the patients were extubated uneventfully. the meth...

The distribution of atherosclerotic lesions within the rabbit vasculature, particularly within the descending thoracic aorta, has been mapped in numerous studies. The patchy nature of such lesions has been attributed to local variation in the pattern of blood flow. However, there have been few attempts to model and characterize the flow. In this study, a high-order continuous Galerkin finite-el...

OBJECTIVE During intraaortic balloon inflation, blood volume is displaced toward the heart (V(tip)), traveling retrograde in the descending aorta, passing by the arch vessels, reaching the aortic root (V(root)), and eventually perfusing the coronary circulation (V(cor)). V(cor) leads to coronary flow augmentation, one of the main benefits of the intraaortic balloon pump. The aim of this study w...

Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...

Congenital anomalies of the great thoracic vessels have been reported in 20% of dogs and cats. In some cases, the vascular ring anomalies remain unrecognized throughout the lifetime of an animal. This report describes a case with an unusual vascular ring anomaly (VRA) that was detected during dissection on a cadaver of an approximately two-year-old male native mixed breed dog. No history of the...

Introduction: Aneurysmal degeneration in patients with chronic type B dissection is common, occurring 20% – 40% of cases, which 10% develop late rupture. Open surgery for these cases associated high morbidity and mortality. Endovascular alternatives include fenestrated or branched endografts, although the use devices may be complex. Treatment usually involves implantation a device true lumen ob...

Correspondence To the Editor: Aberrant right subclavian artery (ARSA) is a congenital vascular anomaly. Stanford‑type A aortic dissection with ARSA is rare. We reported a strategy that involved the use of a four‑branch prosthetic graft to reconstruct the four supra‑arch branch vessels for a Stanford type A aortic dissection with ARSA. A 46‑year‑old male was admitted to Beijing Anzhen Hospital b...
