Anatomical analysis of the left upper lobe of lung on three-dimensional images with focusing the branching pattern of the subsegmental veins.

Background: A clear understanding of the anatomical characteristics of the pulmonary veins (PVs) is essential for the successful performance of segmentectomy and important to avoid intraoperative pulmonary vessels injury. However, there is no report showing the relations between the branching patterns of PVs and pulmonary arteries (PAs). Moreover, internationally accepted symbols for describing PVs remain unavailable.

A successful surgical repair of intraoperative pneumothorax and the diffuse dissection of visceral pleura during liver transplantation surgery via trans-diaphragmatic approach.

Background: Pneumothorax during surgery under general anesthesia is a life-threatening situation for the patient because it can progress easily to the tension pneumothorax due to positive pressure ventilation unless appropriate treatments such as inserting a drainage tube in the thoracic cavity are initiated. The authors experienced a case of intraoperative pneumothorax and the diffuse dissection of visceral pleura during liver transplantation surgery, and achieved successful repair by a trans-diaphragmatic approach without changing patient's body position.

Case Presentation: A 66-year-old male with multiple liver and renal cysts caused by autosomal dominant polycystic kidney disease (ADPKD) was admitted to the authors' hospital for treating the infection of the liver cysts.

[Usefulness of Continuous Suction Unit in Detecting Air Leakage for Pneumothorax].

A 66-year-old male with spontaneous pneumothorax underwent chest tube drainage in other hospital. After tube drainage, chest X-ray showed that the lung fully expanded and an air leakage was not visible. However, clamping the chest tube led to the collapse of the lung, and he transferred to our hospital.

Venous Branching Pattern in a Patient with Hemorrhagic Infarction in the Lingula after the Upper Division Resection of the Left Lung.

Background: Because left upper division resection is similar to right upper lobectomy, this procedure is frequently employed. Few studies have used the anatomic courses of veins evaluated on preoperative computed tomography (CT) imaging to determine what types of patients are at the highest risk for hemorrhagic pulmonary infarction.

Case: We describe our experience with a patient in whom hemorrhagic pulmonary infarction occurred at 6 days after transecting two superior branches (V and V) of the three branches of the left superior pulmonary vein.

Effect of collagen vascular disease-associated interstitial lung disease on the outcomes of lung cancer surgery.

Purpose: This study compared the effect of collagen vascular disease-associated interstitial lung disease (CVD-ILD) with that of idiopathic interstitial pneumonias (IIPs) on the outcomes of lung cancer surgery.

Methods: This study retrospectively reviewed the medical records of patients who underwent surgery for non-small cell lung cancer (NSCLC) and compared the data of 16 patients with CVD-ILD with those of 70 patients with IIPs. The patterns of interstitial lung disease (ILD) on chest computed tomography were classified into usual interstitial pneumonia (UIP) and non-specific interstitial pneumonia (NSIP) patterns.
