The key for this being dissecting aneurysm is that it's a widened aortic arch. Also, there's uneven pulses ("diminished pulses in the left upper extremity") meaning that blood is not passing from the aortic arch to the left subclavian artery (it's not passing the aortic arch).
kevintkim4only thing I would add is the acute nature (30 minutes) and hx of cocaine use helps point towards dissecting aneurysm+1
epiglotittiesAlso, seeing as this is a Stanford type A (involves aortic arch), known complications are acute aortic regurgitation (manifesting in this px as 2/6 diastolic murmur heard best at left sternal border) and cardiac tamponade . :)+
