Hemiparesis is not seen with?
High-Yield Explanation
PICA supplies the lateral pa of the medulla and spares the coicospinal pathway. Hence no hemiparesis is seen. MCA occlusion will damage motor coex leading to hemiplegia. PCA occlusion will damage coicospinal pathway traveling midbrain. Coicospinal pathway traverses the medial pa of medulla which is supplied by the anterior spinal aery.
