Aberrant high-riding innominate artery and right internal carotid artery in the retropharyngeal space

High-riding innominate artery in neck surgery.

We present two cases of innominate artery (IA) in a cervical position. In the first case, surgery was not performed because there was no indication. In the second, it was possible to obtain surgical images of the AI and its branches located in front of the laryngotracheal axis. A warning about the serious risk involved in cervical surgery in these cases is indicated.

In-stent restenosis of innominate artery with critical stenosis of right internal carotid artery.

A lady with aortitis syndrome developed in-stent restenosis (ISR) of the innominate artery stent and critical stenosis of right internal carotid artery. The therapeutic challenge was gaining access to the carotid vessel, after treating the innominate artery ISR and all the while using distal protection to circumvent potential cerebral embolism. Percutaneous transluminal angioplasty (PTA) with o...

Variability in the position of the retropharyngeal internal carotid artery.

The retropharyngeal internal carotid artery (ICA) is a well-described arterial anomaly with important implications for patients undergoing pharyngeal approach surgical procedures. Existing clinical and imaging classification schemes for a retropharyngeal ICA take into account arterial distance to the pharyngeal mucosal wall. We describe a case of mobility of a retropharyngeal ICA between short-...

Report of a Variation of the Right Common Carotid Artery

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...
