WILIS IRLE ARITINS, IMPORTANT FOR CEREBRAL PROTECTION IN AORTIC SURGERY - PRIMARY CT ANGIO DATA.

Unilateral selective cerebral perfusion (SCP) is a method for cerebral protection in aortic arch surgery. However variations of the circle of Willis (CoW) could vitiate its protective effect. The aim of our present work was to make a retrospective analysis of 30 patients, in whom CT angio was performed between January and March 2008.

On the clinical significance of the sternalis muscle.

During routine anatomical dissection, two cases of sternalis muscle were described. In the first case a unilateral sternalis on the left side was observed. It started from the fibres of the sternal membrane, then passed downwards in a slightly arch-shaped course and ended in the pectoral fascia at the level of 6-7 costal cartilages.
