Mechanical asphyxias are those resulting from the mechanical obstruction of the air penetration in the airways. They are usually classified according to the nature of the mechanical mean producing it and the way it performs. Strangulation may be defined as neck constriction through the application of an active force not proper to the body weight, acting by means of a knot, hands, forearm or any stiff structure. In ante brachial strangulation, neck constriction is normally performed surrounding the individual with the arm and forearm. When the neck constriction mechanism is lateral, the airways are not affected: carotid arteries constriction produces a brain stroke and loss of consciousness in 10-15 s. The death mechanism in these cases will be cephalic anoxia. If the neck compression is anterior, it occludes the airways; the pressure on thyroidal and cricoid cartilages may produce fractures and death mechanism will be respiratory obstruction. The current work deals with an uncommon strangulation case, where a combined mechanism led the person to the final decease. For the case discussion the authors took into account the elements of the place, and the examination of the exterior and the inside of the corpse.

Keywords : mechanical asphyxia; ante brachial strangulation; strangulation by hands.
