ABSTRACT
Vascular rings are a rare group of congenital thoracic vascular anomalies which are characterized by abnormal vascular structures that completely or incompletely encircle the trachea, esophagus, or both. We report the case of a vascular ring formed around the trachea and esophagus by aberrant right subclavian artery and aberrant right common carotid artery, associated with persistent left superior vena cava, complete absence of azygos vein, and with multiple nonvascular abnormalities. Recurrent pulmonary infections were the only clinical manifestation of this complex vascular anomaly. Our report represents a so-far-undescribed anatomic variation of the vascular ring that clinicians should be aware of.

A 32-year-old woman presented with nasal obstruction on the right side and a cosmetic defect one year after surgery for nasal hemangioma. On inspection, the right nasal cavity was partly obstructed by a proliferative mass. Computed tomography showed a 2 x 3-cm soft tissue mass that destroyed the nasal bone. The mass was excised completely with the surrounding tissue and the defect was reconstructed with cartilage taken from the cavum conchae. Cartilage graft is appropriate for reconstruction of nasal bone defects because of its easy availability, elasticity, vitality, and good functional and aesthetic results.
