BACKGROUND The purpose of this paper is to present a guideline for beginning video-assisted thoracic surgery (VATS) lobectomy to junior surgeons, and to review the first year experience of a new surgeon performing VATS lobectomies who had not performed a VATS lobectomy unassisted during his training period. MATERIALS AND METHODS A young surgeon opened a(More)
OBJECTIVE Surgical intervention might be required in secondary spontaneous pneumothorax (SSP) with prolonged air leak; however, operation under general anesthesia (GA) could be critical in compromised patients. In this study, we performed video-assisted thoracic surgery (VATS) under epidural anesthesia (EA) in compromised patients with SSP and evaluated its(More)
BACKGROUND The intramural coronary artery has been known as a risk factor for early death after an arterial switch operation (ASO). We reviewed the morphological characteristics and evaluated the early and mid-term results of ASO for patients with an intramural coronary artery. MATERIALS AND METHODS From March 1994 to September 15th 2010, 158 patients(More)
PURPOSE Tracheal resection and end-to end anastomosis (TRE) is known as standard treatment of tracheal stenosis (TS) and there are various methods to keep ventilation during operation. We reviewed ventilation methods and postoperative outcomes in patients with postintubational (PI) or posttracheostomy (PT) TS. PATIENTS AND METHODS From May 2006 to May(More)
INTRODUCTION Extracorporeal membrane oxygenation (ECMO) is widely used to treat respiratory distress during cardiac or respiratory arrest; moreover, its use is being extended to a wide variety of clinical fields. In this study we assess the utility of ECMO in the management of airway obstruction. PATIENTS AND METHODS 15 patients underwent ECMO for airway(More)
Although osteomyelitis is a very rare complication of Bacillus Calmette-Guérin (BCG) vaccination, sternal osteomyelitis as a late complication of BCG vaccination diagnosed by polymerase chain reaction (PCR) in a child is described.We might consider BCG osteomyelitis in the case of osteomyelitis without bacterial isolation within a year after BCG(More)
Pulmonary extrauterine epithelioid trophoblastic tumors (ETTs) are extremely rare. A 26-year-old nonsmoking woman with a history of a suspected subclinical miscarriage presented with a large mass in the right lower lobe that was confirmed to be a pulmonary extrauterine ETT using immunohistochemical stains. When a nonsmoking fertile woman presents with a(More)
PURPOSE Malignant pleural effusion (MPE) is common in patients with advanced cancer. Chemical pleurodesis can be considered for MPE that do not respond to chemotherapy, radiotherapy, or therapeutic thoracentesis. However, it is not yet clear which agent is more effective and safer in chemical pleurodesis. METHODS This study was designed as a single arm,(More)
BACKGROUND Endovascular aortic aneurysm repair (EVAR) has come into use and been widely extended because of the low complication rate and less-invasiveness. This article aimed to describe our experience in the treatment of abdominal aortic aneurysm with EVAR. MATERIALS AND METHODS A retrospective review was conducted for the 22 patients who underwent EVAR(More)
Anesthetic management of critical airway stenosis is often very challenging. Extracorporeal membrane oxygenation (ECMO) may provide adequate respiratory support when conventional approaches fail. We report our experience of ECMO support for critical airway surgery. Between April 2012 and March 2015, nine patients underwent ECMO-supported airway operation.(More)
