In this study, the aim was to investigate the anatomy of the aortic arch arteries in mole-rats (Spalax leucodon). Six adult mole-rats were used for this purpose. Coloured latex was injected into the left ventriculus of the hearts of all animals. The materials were carefully dissected and the arterial patterns of arteries originating from the aortic arch were examined. The brachiocephalic trunk,...

Dissecting aneurysm is the condition produced by separation of the layers of the arterial wall by circulating blood. Although rare, the coexistence of aortic dissection and aberrant right subclavian artery may be catastrophic. In this study we report the endovascular treatment of a patient with thoracic aorta dissection associated with aberrant right subclavian artery. Aortic clamping proximal ...

We recently read the interesting article by Albayram et al (1), which concisely explained the anomalies of the vertebral arteries. We would like to present another rare case of bilateral vertebral arteries originating from the aortic arch. We incidentally diagnosed this condition on the basis of findings on a chest CT scan obtained in a patient with trauma. Our trauma chest CT protocol uses 8 2...

PURPOSE The aim of this study was to introduce the phenomenon that stenosis or occlusion occurs less frequently in the innominate artery than in the right subclavian and common carotid arteries, which are not first-order branches of the aorta, in Takayasu arteritis (TA). MATERIALS AND METHODS We retrospectively reviewed the medical records and image findings of all patients who were diagnosed...

In this article, we present 5 cases of uncommon anomalous vertebral arteries and discuss the possible embryologic etiologies. These cases include a left vertebral artery as the 2nd branch off the left subclavian, a left vertebral artery with 2 origins, a right vertebral artery arising as the last branch off the aorta, a right vertebral artery arising as the 2nd branch off the right subclavian a...

PURPOSE The present study was performed to compile normative data for dimensions of the left subclavian artery at varying gestational age. MATERIAL AND METHODS Using anatomical dissection, digital image analysis (Leica Q Win Pro 16 system) and statistical analysis (ANOVA, regression analysis) a range of measurements (length, original external diameter, volume) for the left subclavian artery i...

We present the case of a 49-year-old woman with neurological symptoms and severe atherosclerosis of aortic arch branches affecting subclavian and carotid arteries. Our patient has a history of transient ischemic attack and recurrent paresthesias of her right arm. We present a double access intervention using a distal embolic neuroprotection device during ostial right subclavian artery recanaliz...

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...
