Is vertebral artery dissection curable?

Generally not: The 2 vertebral arteries arise from the left and right subclavian arteries and supply the brainstem and cerebellum. Dissection is rare (2.5/100, 000), affect women to men 3:1 and can cause stroke in people <age 45. It may follow minor head trauma, yoga, painting a ceiling. 50% have hbp. Treatment is supportive. Blood thinners are used if bleeding is ruled out. Surgery is not usually an option.

Treatable yes: Many times will heal on its own. May require a stent.

YES: This could happen spontaneous or traumatic. Typically asymptomatic especially if affecting one side with normal connection between both vertebral arteries. Typically managed with anticoagulation like Coumadin (warfarin) or even with antiplatelet agents like Aspirin and most probably will heal. In rare situation they can be stented.
