VATS-IFRR was safe and had several advantages. Thus, VATS-IFRR is a minimally invasive surgical option suitable for treating selective cases of TOS.

BACKGROUND: Non-intubated thoracoscopic surgery can be performed under sedation using adjuvant regional anesthesia, however, the benefits of non-intubated thoracoscopic surgery under sedation have not yet been completely verified. In this study, we compare the perioperative safety and pain complaints of sedation without intubation in thoracoscopic bullectomy with that of conventional general anesthesia with double-lumen intubation and mechanical ventilation. METHODS: Forty-one patients with prim

We report a case of giant cell tumor originating from the anterior arc of the rib. The tumor and the surrounding chest wall were completely resected, and the chest wall defect was covered with Marlex mesh. Giant cell tumor of the bone usually originates from the epiphysis of long bones. Even when the tumor occur in ribs, it usually occur in the posterior aspect. However, giant cell tumor should be included in the differential diagnosis of a tumor originating from the anterior arc of the ribs.

Plasmacytomas are a localized proliferation of plasma cells in the bone marrow, and are less frequently seen in extraosseous organs or tissues. Extramedullary plasmacytoma is a rare malignant neoplasm, and is especially uncommon when it arises from the mediastinum. Here, we report on a case of posterior mediastinal extramedullary plasmacytoma in a 64-year-old man. He was admitted with an asymptomatic right apical mediastinal mass, which was provisionally diagnosed as a neurogenic mass. However,

Since it is known that a 307 bp fragment of the position specific regulatory element of human HOXA-7 contains two (DR3 and DR5) retinoic acid response elements (RAREs) at its 3' end, we constructed several deletion constructs containing different numbers of RAREs and examined their effects in vitro and in vivo. The 5' deletion constructs, BM112 and OM213, retaining both RAREs, were highly responsible (about 8 fold induction) for RA in F9 teratocarcinoma cells, versus NM307 (4-5 fold). The constr

Lymphomatoid granulomatosis (LYG) is a rare angiocentric and angiodestructive lymphoproliferative disease characterized by Epstein-Barr virus-positive B cells admixed with reactive T cells. LYG most commonly affects the lung but can also involve other extrapulmonary sites. Pulmonary LYG usually presents as multiple pulmonary nodules with rapid progression and excavation. It can mimic various infectious diseases, vasculitis or metastatic malignancy and is difficult to be diagnosed clinically. Sta

Most patients needing implantation of a ventricular assist device (VAD) require repeated sternotomy; some after cardiac surgery, and others later for heart transplantation. The purpose of this study was to establish the right thoracotomy technique as an alternative for VAD implantation to reduce repeated sternotomy-related morbidity and mortality. We performed a right thoracotomy in animals, preclinical cadaver fitting tests, and a clinical case. A total of 20 various animals underwent right tho

A Korean artificial heart (AnyHeart) has been implanted in 29 various animals (52-470 kg) to evaluate hemodynamic performance and electromechanical stability. Most were implantable biventricular assist devices in use. A right thoracotomy approach has been a standard technique of implantation. A preclinical fitting test was also performed to observe anatomical feasibility and to compare surgical techniques in 10 human cadavers. The first case of human application was made as a lifesaving procedur

This study was conducted to evaluate the mid-term results of cervical esophagogastric anastomosis using a side-to-side stapled anastomosis method for treatment of patients with malignant esophageal disease. A total of 13 patients were reviewed retrospectively from January 2001 to November 2005 who underwent total esophagectomy through a right thoracotomy, gastric tube formation through a midline laparotomy and finally a cervical esophagogastric anastomosis. Average patient age was 62.6 yr old an

A 44-year-old man with congenital aortic coarctation experienced acute dissection that crossed the coarctation and extended to both iliac arteries. The primary entry of the dissection was proximal to the coarctation segment, just below the origin of the left subclavian artery. Surgical procedures involved resection of the diseased segment including the coarctation, and graft interposition.
