BACKGROUND AND SIGNIFICANCE We describe a method by which to efficiently and atraumatically achieve distal positioning of a flexible guiding catheter beyond extreme cervical tortuosity using a hypercompliant temporary occlusion balloon. METHODS A retrospective review of a prospective neuroendovascular database was used to identify cases in which a hypercompliant balloon catheter (Hyperform or...

Carotid artery is the most important artery that carries the major part of the blood supply to the head and neck. The branching of the common carotid artery usually occurs at the upper edge of the thyroid cartilage. The placement of carotid sinus has also increased its importance in this area. Considering the clinical importance of knowledge about carotid artery variations, this case is reporte...

An 83-year-old man presented with drowsiness, dysarthria, anosognosia, forced right gaze deviation and left hemianopia, hemiplegia, and hemianesthesia consistent with a right hemispheric stroke. A painless, nonpulsatile, right cervical mass was noted. CT angiography demonstrated a right carotid body tumor (CBT) occluding the ipsilateral internal carotid artery (figure) and a fetal-type right po...

the branches of external carotid artery were dissected and studied in six one humped camels.these specimens were preparated from slaughterhouse and fixed in10% formaline. the common carotid artery in one humped camel is divided into three branches , including , occipital artery , internal carotid artery and external carotid artery which in this respect it was similar to that of equine. external...

the autonomic nervous system consists of a vast range of nerves and ganglions. anatomical studies have demonstrated that the sympathetic innervations of the head and neck are affected by the neurons that ramify from the cranial cervical ganglion (ccg). the ccg is the end of the sympathetic cervical trunk, which runs with the vagal nerve during its cervical course. in this study sixteen adult (2...

BACKGROUND Limited data exists on the durability and occlusion rate of treating extracranial cervical internal carotid artery pseudoaneurysms using the pipeline embolization device (PED) flow-diverting stent. METHODS Three patients presenting with dissecting cervical internal carotid artery pseudoaneurysms were treated with the PED as the sole treatment modality. RESULTS In all three patien...

Cervical internal carotid dissection is not rare. Doppler ultrasound screening of young patients presenting with stroke, identified 10 patients with reduced common and internal carotid blood flow without any evidence of atheroma. Eight, on angiography proved to have a dissection of the cervical internal carotid artery. All were managed conservatively. Seven received anticoagulant therapy, stopp...

OBJECTIVE Surgical resection of complex glomus vagale tumors can be complicated by extensive blood loss and might require surgical sacrifice of an encased internal carotid artery. METHODS A young patient presented with mass effect from glomus valage tumor. Computerized tomography angiography showed an encased internal carotid artery. Cerebral angiography demonstrated a highly vascular tumor....

Changes of regional cortical blood flow (rCBF) was monitored by the heat clearance method during the operation of cervical carotid ligation combined with superficial temporal artery and middle cerebral artery anastomosis for the treatment of inaccessible aneurysms of the internal carotid artery in eight patients. There were three types of rCBF responses upon closure of the internal carotid arte...
