A rare morphology of an aberrant innominate artery (IA) is reported here, together with additional arterial variation encountered in the respective specimen. The IA originated in the aortic arch on the left side of the trachea, coursed on that side of the trachea to reach the left thyroid lobe, turned in at a right angle to pass anterior to the trachea and immediately inferior and parallel to t...

Introduction The vertebral artery (VA) is important to posterior cerebral circulation. It arises from the superior surface of the first part of the subclavian artery medial to the scalenus anterior muscle. The vessel takes a vertical posterior course to enter into the transverse process of the sixth cervical vertebra. It continues through the transverse foramina of the cervical vertebrae and af...

A 42-year-old man presented with asymptomatic traumatic carotid artery dissection 3 months after sustaining blunt injury with tracheal laceration. Magnetic resonance imaging performed as a screening procedure for asymptomatic carotid artery injury unexpectedly showed dissection of the carotid artery. Angiography confirmed carotid artery dissection with narrowing of the true lumen. Balloon angio...

Blunt or nonpenetrating trauma to the head and neck occasionally results in damage to the cervical segment of the internal carotid artery. This may produce neurologic signs and symptoms that mimic acute craniocerebral injury. The mortality and morbidity associated with these injuries are alarmingly high. These injuries may be missed if one relies only on computed tomography. Angiography is stil...

Objective: Two cases in which emergency retrograde stenting were performed for occlusion of the left common carotid artery orifice that occurred during thoracic endovascular aortic repair are reported. Case Presentations: In males in their 70s with thoracic aortic aneurysm, oxygen saturation dropped in the left cerebrum immediately after deployment of the thoracic aortic stent graft under gener...

Acute symptomatic occlusion of the cervical internal carotid artery (ICA) can be treated by intravenous administration of tissue plasminogen activator, percutaneous transluminal angioplasty, and carotid endarterectomy. Carotid artery stenting (CAS) is now indicated for cervical ICA stenosis, but the safety and the efficacy of urgent CAS have not been established. We retrospectively reviewed 10 ...

The records of 628 patients admitted to the Joint Study of Extracranial Arterial Occlusion with transient symptoms of carotid system ischemic disease were examined to determine the accuracy of predicting disease of the extracranial internal carotid artery on the basis of clinical information alone. A patient with a history of episodes of amaurosis fugax is more likely to have a lesion of the in...

In the present study, eight specimens of sheep (>1 year) of both sexes were dissected to provide a comprehensive description of the weight, allocation and nerve branches of the cranial cervical ganglion. The cranial cervical ganglion was found beneath the mandibular salivary gland. It was located ventromedial to tympanic bulla and ventrally to atlantic fossa. In three out of eight animals it wa...
