Clinical outcomes of intra-arterial thrombectomy versus medical therapy for isolated posterior cerebral artery occlusion

Patients with isolated PCA occlusion, higher serum albumin levels, and lower NIHSS scores at admission had favorable outcomes, underscoring the potential prognostic value of patients' nutritional status at admission. Relatively high NIHSS scores at admission, even during IAT, resulted in minimal procedure-related complications and a minimal difference in outcomes over time. Therefore, prompt IAT should be considered for patients with isolated PCA occlusion and severe symptoms at admission.
