Indocyanine green-enhanced thoracoscopic localization of parasternal lymph node: How to do it.

Small, non-palpable, parasternal lymph nodes can be difficult to locate during minimally invasive thoracoscopy. We here present a simple technique for thoracoscopic localization of small parasternal lymph nodes using echo-guided injection of indocyanine green. This technique rapidly marks the whole chain of enhanced lymph nodes for radical resection, enabling accurate endoscopic resection of small parasternal lymph nodes.
