主动脉夹层动脉瘤是一种严重的心血管疾患,起病急,病情凶险,可突然破裂引起猝死。临床表现复杂多样,较难确诊;涉及损伤的主动脉夹层动脉瘤破裂致死的案件鉴定,尤须引起注意。据报道,60-70%的夹层动脉瘤起源于升主动脉,25%起源于近段降主动脉,约90%的病例伴有高血压。夹层动脉瘤形成后,可向远段主动脉延伸,累及胸主动脉全长和腹主动脉及其分支;向近段 Aortic dissection aneurysm is a serious cardiovascular disease, acute onset, dangerous condition, sudden death can cause sudden death. The clinical manifestations of complex and diverse, more difficult to diagnose; involved in the injury of dissecting aortic aneurysm rupture lethal case identification, special attention. It has been reported that 60-70% of dissecting aneurysms originate in the ascending aorta, 25% originate in the proximal descending aorta, and about 90% of cases have hypertension. After the formation of dissecting aneurysms, can extend to the distal aorta, involving the full length of the thoracic aorta and its abdominal aorta and its branches; to the proximal segment
