Mechanical Thrombectomy for Fetal Posterior Cerebral Artery Occlusion in Acute Stroke

Fetal posterior cerebral artery (FPCA) occlusion represents an unusual presentation of potentially disabling acute ischemic stroke, with few published case reports and studies describing this entity. While mechanical thrombectomy has been established as safe and effective in acute large vessel occlusions, no study has included the FPCA. We present the case of a 76‐year‐old with left facial droop, left hemianopia, left hemiparesis, dysarthria, and impaired consciousness who was diagnosed with a right FPCA occlusion. CT angiography showed a right FPCA with proximal occlusion, with CT perfusion imaging demonstrating 64 cc of hypoperfusion. The patient was successfully treated with mechanical thrombectomy using a combination of aspiration and stent retrieval, resulting in clinical improvement. Although mechanical thrombectomy in a FPCA occlusion requires further investigation, the case supports this treatment as effective and safe.
