就胸部的急减速伤而言，例如，当高速交通工具撞击固定物体时，由于胸降主动

In terms of sudden deceleration of the chest, for example, when a high-speed vehicle hits a fixed object, the brachiocephalic artery is anchored at the thoracic outlet because the proximal thoracic descending aorta is anchored to the thoracic by the arterial catheter ligament and intercostal artery The proximal thoracic descending aorta and brachiocephalic artery will slow down with the thoracic cage, but the blood in the distal aortic arch and its lumen will continue to move forward due to inertia, and the aorta near the isthmus will be subjected to this huge shear force And it broke.

In the case of chest rapid deceleration injuries, for example, when a high-speed vehicle hits a fixed object, the aortic artery is anchored to the chest because the near section of the aorta is anchored by the arterial catheter ligament and the inter-rib artery, the head arteries are anchored to the chest outlet, the chest aorta near and the head arm artery will decelerate with the chest profile, but the aortic arch and the blood in the cavity will continue to move forward due to inertia, and the main artery near the fjord will be severely sheared.

In the case of rapid deceleration injury to the chest, for example, when a high-speed vehicle impacts a fixed object, because the proximal part of the descending thoracic aorta is anchored to the thorax by the artery conduit ligament and intercostal artery, and the cephalobrachial artery is anchored to the outlet of the thorax, the proximal part of the descending thoracic aorta and the cephalobrachial artery will decelerate with the thorax, but the blood in the distal part of the aortic arch and its lumen will continue to move forward due to inertia Moving, the aorta near the isthmus will be ruptured by this huge shear force.<br>
