Hypertension at time of presentation (49% of all cases)
Ascending Aorta
Acute<unk>  regurgitation, leading to a diastolic decrescendo murmur, hypotension, or heart failure, in 50%-66%
MI/Ischemia on ECG, usually inferior (dissection affects the right coronary artery more often than the left coronary artery)
Cardiac Tamponade
Hemothorax - if adventitia disruption
Horners, partial - sympathetic ganglion
Voice hoarseness - recurrent laryngeal nerve compression
CVA/Syncope - if carotid extension
Neurological deficits
SBP>20mmhg difference between arms
Hypertension at time of presentation (35.7% of all cases)
Descending Aorta
Chest pain, back pain, abdominal pain
Pain abrupt, severe (90% of patients) radiating to back
Hypertension at time of presentation (70.1% of all cases)
Hemiplegia, neuropathy (15%)
Renal failure
Distal Pulse deficits/ limb ischemia
Mesenteric ischemia
Acute<unk>  regurgitation, leading to a diastolic decrescendo murmur, hypotension, or heart failure, in 50%-66%
