Mechanical Thrombectomy in Basilar Artery Stroke Attributable to Persistent Primitive Proatlantal Intersegmental Artery: A Case Report

Objective This clinical note describes a patient who presented with acute basilar artery occlusion and persistent primitive proatlantal artery. Case Presentation We present the case of an 82‐year‐old woman sudden onset left‐sided weakness. Cross‐sectional imaging revealed She then underwent successful mechanical thrombectomy. Complete reperfusion was achieved; thereafter, she recovered well from ischemic stroke discharged home. Discharge modified Rankin Scale score <2. Conclusion is first report thrombectomy in Embryonic carotid vertebral anastomosis rarely persists adult patients. Prompt accurate recognition these embryonic anastomoses paramount importance interpreting cross‐sectional planning revascularization procedures.
