Partial persistence of the primitive lateral basilovertebral anastomosis of Padget
Persistência parcial da anastomose basilovertebral primitiva lateral de Padget
A hypertense, smoker, and alcoholic 30-year-old men presented with vertigo and multidirectional nystagmus lasting 30 days. Magnetic Resonance Imaging (MRI) showed subacute vermian infarction ([Figures 1A and 1B]). He underwent digital subtraction angiography ([Figures 1C and 1D]), which revealed duplication of the vertebrobasilar circulation through a branch of the right vertebral artery, connected to the main circulation by a hypoplastic branch, compatible with partial persistence of the primitive lateral basilovertebral anastomosis of Padget (PLBA) originating the left posterior inferior cerebellar artery ([Figures 2A and 2B]), an embryonic remnant. PLBA persistence increases stroke chances because of the abnormal pattern of arterial supply territories and subsequent deficient collaterality[1],[2].
