[Flap transverse sternotomy during operations on the vessels and organs of the upper mediastinum and the first cervical zone].

A surgical approach to vessels and organs of the upper mediastinum was grounded, developed and tested. An experimental study of flap transverse sternotomy was carried out in 20 cadavers. A wide approach with throwing of the presternum was the best for manipulations in proximal parts of the aortic branches. This approach was also less traumatic.
