Thoracoscopic right S⁹⁺¹⁰ segmentectomy

S⁹⁺¹⁰ segmentectomy is a challenging operation, especially when done through a thoracoscopic approach, because of the highly variable distribution of arteries and veins and of the special shape of these segments that make identification and division of the intersegmental plane difficult. Preoperative modelisation of bronchovascular anatomy is crucial and the use of dye marking of the intersegmental plane—whatever the method—is helpful.
