Summary

The clinical characteristics of painless aortic dissection were investigated in order to improve the awareness of diagnosis and treatment of atypical aortic dissection. The 482 cases of aortic dissection were divided into painless group and pain group, and the data of the two groups were retrospectively analyzed. The major clinical symptom was pain in 447 cases (92.74%), while 35 patients (7.26%) had no typical pain. The gender, age, hypertension, hyperlipidemia, diabetes, smoking and drinking history had no statistically significant differences between the two groups (P>0.05). The proportion of Stanford type A in painless group was significantly higher than that in pain group (48.57% vs. 21.03%, P=0.006). The incidence of unconsciousness in the painless group was significantly higher than that in the pain group (14.29% vs. 3.58%, P=0.011). The incidence of hypotension in painless group was significantly higher than that in pain group for 4.26 folds (P=0.01). Computed tomography angiography (CTA) examination revealed that the incidence of aortic arch involved in the painless group was significantly higher than that in the pain group (19.23% vs. 5.52%, P=0.019). It was concluded that the incidence of painless aortic dissection was higher in Stanford A type patients, commonly seen in the patients complicated with hypotension and unconsciousness. CTA examination revealed higher incidence of aortic arch involvement.
