Uniportal thoracoscopic anterior and lingular (S3+4+5) segmentectomy of the left upper lobe using intravenous indocyanine green.

Although an anterior and lingular (S3+4+5) segmentectomy of the left upper lobe is rarely performed, this type of segmentectomy is very useful to ensure a sufficient margin when the tumor is located at the border between the anterior segment (S3) and the superior lingular segment (S4). However, it might be technically difficult to perform this unusual segmentectomy via a uniportal approach because of the limited angulation and exposure of the peripheral vessels/bronchi. We present the successful results of a patient undergoing uniportal thoracoscopic S3+4+5 segmentectomy of the left upper lobe and describe some technical details.
