Computed tomography-guided patent blue vital dye localization of pulmonary nodules in uniportal thoracoscopy.
Due to the limitations of the small single incision, an ideal preoperative localization technique is essential for surgical resection of small pulmonary nodules by uniportal video-assisted thoracoscopic surgery (VATS). The aim of this study is to evaluate the usefulness and safety of preoperative computed tomography (CT)-guided patent blue vital (PBV) dye localization in patients with small indeterminate pulmonary nodules who have undergone uniportal VATS for lung resection. ⋯ Preoperative CT-guided PBV dye localization is a feasible, safe, and accurate procedure. It makes uniportal VATS easy for small, poorly located pulmonary nodules with GGO predominance and synchronous multiple nodules.

Relationship between pulmonary arterial resistance and compliance among patients with pulmonary arterial hypertension and congenital heart disease.
It is unknown whether changes in pulmonary arterial resistance (Rp), pulmonary arterial compliance (Cp), and the product of Rp and Cp (the RC time) in patients with pulmonary arterial hypertension (PAH) are related to an increase in pulmonary blood flow. The aim of this study is to clarify relationships between these parameters before and after corrective surgery among patients with PAH and congenital heart disease. ⋯ Rp-Cp coupling depends on both the amount of pulmonary blood flow and the condition of the pulmonary vasculature. Lower preoperative Cp is an independent predictive factor to predict higher postoperative pulmonary systolic pressure leading to an increase in right ventricular workload. It is necessary to assess Rp-Cp coupling before surgery among patients with PAH related to congenital heart disease.
