Painless dissection has also been reported in rare cases and might be misdiagnosed due to its atypical symptoms leading to catastrophic outcomes. Case presentation: The patient was admitted to the hospital due to right limb weakness with speech inability for more than 10 hours. In the routine cardiac ultrasound examination, the avulsion intimal echo was found in the initial segment of the descending aorta. The rupture range was about 11 mm, and the lumen was separated into real and false lumen. Further computed tomography angiography (CTA) examination confirmed the major arterial dissection (De Bakey Type I). Conclusion: We report a case of painless aortic dissection with active carotid artery thrombosis diagnosed by ultrasound and CTA, and to improve the understanding of painless aortic dissection by reviewing relevant domestic and foreign literature.展开更多

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 signifi-cantly 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 aor-tic arch involvement.展开更多

While painless acute aortic dissection(AAD)is the most common catastrophic event that can mimic myelopathic manifestations of acute bilateral limb weakness, it is often easily ignoredWe describe a case of painless AAD in a 70-year-old man with a history of hypertension manifesting as acute myelopathy(bilateral limb weakness and loss of all types of sensation)with increased levels of serum myoglobin and D-dimer.Magnetic resonance imaging of the spinal cord revealed a normal thoracic and lumbar spinal cord but a dissection of the thoracic aorta. Computed tomography angiography of the chest and abdominal aorta showed a Stanford type B dissection extending throughout the thoracic aorta and into the abdominal aorta hypomere.The patient died because of a sudden drop in blood pressure during transfer to vascular surgery.The clinical presentation of painless AAD mimics myelopathies.Aortic dissection should be considered in patients presenting with acute bilateral limb weakness.Physical examination of the skin temperature,dorsalis pedis artery,serum D-dimer,and myocardial markers can provide diagnostic clues.展开更多
