The Sistine Chapel and clothesline signs: a tale of two arteries

An 83-year-old woman presented sudden vertigo, drop attack, and transient dysarthria after head hyperextension to see the Sistine Chapel ceiling, in the Vatican. Transcranial doppler ultrasound ([Figure 1]) suggested proximal basilar stenosis, confirmed by arteriography ([Figure 2]). Case 2: A 77-year-old woman presented a 1-year history of transient vertigo after hanging clothes on a clothesline. Transcranial doppler ultrasound ([Figure 3]) revealed left subclavian artery steal phenomenon secondary to proximal subclavian artery stenosis, confirmed by arteriography ([Figure 4]). They received stenting and dual antiplatelet therapy. Transient ischemic symptomatology triggered by head/neck and arm movements demands vertebrobasilar and subclavian evaluation.[1] [2] [3]

Figure 1 Transcranial Doppler show signs of segmental increase in flow velocity in the proximal basilar artery, compatible with basilar artery stenosis.

Figure 3 Systolic flow reversal in the left vertebral artery at transcranial doppler ultrasound (arrow), compatible with grade 2 subclavian steal syndrome (intermittent or partial).
