Complete Thoracoscopic Sublobar Resection for Intralobar Pulmonary Sequestration Using Indocyanine Green Fluorescence: A Case Report with Literature Review

INTRODUCTION: Intralobar pulmonary sequestration (IPS) is a congenital pulmonary anomaly supplied by an aberrant systemic artery. Although surgical resection is the standard treatment, complete thoracoscopic lung-preserving (sublobar) resection can be technically demanding because the border between normal and sequestrated lung may be unclear, particularly in the presence of inflammation or pleural adhesions. Indocyanine green (ICG) fluorescence imaging provides real-time perfusion-based demarcation without requiring lung inflation. We present a case of IPS treated by complete thoracoscopic sublobar resection under ICG guidance and review the literature to clarify the role of ICG in complete thoracoscopic lung-preserving surgery for IPS.
