[Aberrant birth of a radial artery in the upper third of the forearm: A case report].

We report the case of a 68-year-old patient, operated on in our department of a quadruple coronary bypass grafting. The grafting strategy consisted initially on harvesting the left internal thoracic artery and the left radial artery. The harvest of this latter failed because of a rare anatomical variation of the radial artery, which rose from the confluence of two branches: a superficial and a deep radial artery at the proximal third of the forearm approximately 10cm below the elbow.

Use of the endotracheal tube as a pharyngeal airway.

An animal study was conducted to determine whether an endotracheal tube placed above the vocal cords in the pharynx can be used for ventilation. Four dogs undergoing general anesthesia were ventilated through an endotracheal tube placed in the oropharynx with the remainder of the airway occluded. Ventilation was performed for 3 of every 5 minutes during a total period of 25 minutes.
