Abstract: Background: Acute aortic syndrome (AAS) is a group of serious and lethal aortic emergencies, which have so variable and non-specific clinical presentations and can be misdiagnosed as other diseases. AAS occurs frequently in daily life, but too little attention was paid on the location of its vascular flap according to different daily activity patterns.

Methods: The data of 160 cases hospitalized for non-traumatic acute aortic syndrome in Chinese PLA general hospital from January 1st, 2004 to December 31st, 2013 were analyzed retrospectively. Among the 160 patients enrolled, 155 (96.9%, of160) were finally diagnosed with acute aortic dissection (AAD) and the other 5 (3.1%, of 160) with ruptured aortic aneurysm (RAA). Of those155 patients with AAD, 45 (29.0%, of 155) were definitely diagnosed with type A and 110 (71.0%, of 155) for type B according to the Stanford classification system.

Results: (1) Flaps of aorta in AAS patients were found more commonly located in the thoracic descending aorta (68.1%, 109/160), and the other 24 cases (15.0%, 24/160) in the ascending aorta, 21 cases (21/160, 13.1 %) in aorta arch, and only 6 cases (6/160,3.8%) in the abdominal aorta. (2) There are 65 AAS patients (40.63%) with the body postural changes, 44 (27.50%) for body stretching, 25 (15.63%) for weighting, 17 (10.63%) for pound on the anterior body, 5 (3.13%) for turning the steering wheel and 4 (2.50%) for cycling during the onset of disease. (3) In the body postural changes group, the vessel flaps were dominantly found on thoracic descending aorta (76.92%, 50/65), which was significantly higher than the others (62.11%, 59/95; X²=3.902, P=0.040). (4) In the body stretching group, the vessel flaps on thoracic descending aorta were frequently (56.82%, 25/44), and on the ascending aorta was 31.82% (14/44), which significantly higher than the body postural change group (4.63%, 3/65; X²=15.028, P=0.0001) (5) The proportion of aortic arch flaps in the weighting group was 28.57% (6/21), which was significantly higher than the others (11.11%, 15/135; X²=3.073, P=0.081). (6) The frequency of the ascending aorta flap location in the pound on the anterior body group was significantly higher than the other activities (41.18%, 7/17 vs. 11.89%, 17/143; X²=10.222, P=0.001); and the abdominal aorta was also significantly higher than the other activities (16.65%, 3/17 vs. 20.98%, 3/143; X²=10.178, P=0.001). (7) There were 9 cases (5.63%, 9/160) with the twist movement(turning the steering wheel and cycling) had vascular flaps situated in thoracic descending aorta, which significantly higher than the others (100.00%, 9/9 vs. 65.56%, 99/151; X²=4.592, P=0.032).

Conclusions: These results showed the location of vascular flap is highly related with daily activity pattern in nontraumatic acute aortic syndrome, which might be useful for clinicians when they prevent and cure this disease more timely and effectively.
