Normal chest radiograph does not exclude dissection
Maintain imaging threshold with high-risk features
Painless dissection presentations
Syncope
Stroke-like symptoms
Ischemic ECG changes can coexist with dissection
Avoid routine thrombolysis without excluding dissection when features present
Vasodilator-first strategy
Reflex tachycardia and increased shear stress risk
PEARLS
High-yield pearls
Pain plus tachycardia equals shear stress
Analgesia plus anti-impulse therapy early
Type A is a surgical emergency
Imaging and transfer decisions measured in minutes
Check bilateral arm BP and pulses when feasible
Abnormal findings increase suspicion but absence does not exclude
