Abstract
Thoracoscopic pulmonary lobectomy (TPL) is extremely challenging in cases where severe incomplete fissure causes densely fused pulmonary lobes (DFPL) since pulmonary arteries (PAs) are buried and completely concealed by DFPL. We describe TPL for DFPL including a technical tip to prevent pitfalls. Four congenital pulmonary airway malformation (CPAM) and DFPL (left-upper: 2, left-lower: 1, right-middle: 1) were treated. During TPL, DFPL prevent interlobar PAs from being identified and searching for them only promotes bleeding and air leakage, serious pitfalls that affect the safety and success of TPL. Our tip is to ligate and divide the pulmonary veins (PVs) at the pulmonary hilum and the hilar PA supplying the CPAM lobe to expose the bronchus of the lobe, which is then ligated and divided. The main PA supplying the lobe running underneath the DFPL is exposed and visible from the pulmonary hilum allowing the PA supplying the lobe to be ligated and divided safely. A line demarcating the fused fissure becomes apparent, and an endoscopic stapler or EnSeal® device can be used to divide the DFPL along the line taking great care not to injure the main PA or interlobar PAs. There were no intra-/postoperative complications in any case. All patients performed well without respiratory tract-related symptoms after a mean follow-up of 4.6 years. TPL for DFPL in children with CPAM can be performed safely and successfully as a virtually bloodless procedure and without incidence of air leakage by ligating and dividing the PA after dividing the PVs and bronchus to the lobe.
