Case ReportsPulmonary artery hypoplasia associated with posterior mediastinal hematoma accompanied by a ruptured pseudoaneurysm of the esophageal branch of the left gastric artery.
A 65-year-old woman with no significant medical history visited the emergency department complaining of epigastric discomfort. A computed tomography of the thorax and abdomen showed the attenuation of the pulmonary artery and a posterior mediastinal hematoma. Angiography showed a tortuous esophageal branch of the left gastric artery and a pseudoaneurysm, and during the later phase, the left lower lobe of the lung was enhanced, and finally, the left pulmonary vein was enhanced. ⋯ Transcatheter arterial embolization was performed. The patient has not experienced any recurrence of a ruptured pseudoaneurysm or epigastric discomfort. Here, we report the first documented case of pulmonary artery hypoplasia associated with posterior mediastinal hematoma accompanied by a ruptured aneurysm of the left gastric artery.

Comparative StudyImportance of multidisciplinary management for pulmonary atresia, ventricular septal defect, major aorto-pulmonary collateral arteries and completely absent central pulmonary arteries.
To review long-term clinical outcomes for pulmonary atresia, ventricular septal defect (PA/VSD), major aorto-pulmonary collateral arteries (MAPCAs) and completely absent central pulmonary arteries (cPAs). ⋯ Staged midline approach with PTA seemed feasible strategy to go on to definitive repair. Patency of MAPCAs and reconstructed cPAs were maintained by the aggressive PTA after the definitive repair.

New PET/CT criterion for nodal staging in non-small cell lung cancer: measurement of the ratio of section area of standard uptake values ≥2.5/lymph node section area.
The aim of the present study was to use surgical and histological results to develop a simple noninvasive technique for improving nodal staging using preoperative PET/CT in patients with resectable non-small cell lung cancer (NSCLC). ⋯ When diagnosing nodal staging based a lymph node SUV ≥2.5 SA/node SA ratio of ≥1.0, it can be an effective criterion for use to determine surgical indications.

Micropapillary histological subtype in lung adenocarcinoma of 2 cm or less: impact on recurrence and clinical predictors.
This study examined the clinical and radiological characteristics of adenocarcinoma having the micropapillary histological subtype. ⋯ The micropapillary component in adenocarcinoma should be regarded as indicative of a high-grade malignancy and was associated with the HRCT finding.

Atrial fibrillation following aortic valve replacement: impact of perioperative use of intravenous β-blocker.
Despite recent advances in perioperative management, postoperative atrial fibrillation/flutter (POAF) remains the most common complication after cardiac surgery. Therefore, it is important to determine related risk factors to establish effective management. However, most studies have focused on patients undergoing coronary artery bypass grafting and little is known about POAF in those who receive aortic valve replacement (AVR). We investigated the relationship of clinical predictors with POAF in patients undergoing AVR. ⋯ POAF frequently occurred in patients undergoing AVR, and was significantly related to prolonged ICU stay and postoperative stroke. Our findings show that advanced age and absence of preoperative β-blocker usage are risk factors for POAF. Furthermore, in patients undergoing AVR, perioperative intravenous β-blocker administration may be useful for prevention.
