Endovenous 980-nm Diode Laser Treatment of Incompetent Great Saphenous Vein / 대한흉부외과학회지

BACKGROUND: Endovenous laser treatment has recently been introduced as a less invasive technique, with many good results reported. A 980-nm diode laser was used on the great saphenous vein (GSV) occlusions in patients with varicose veins, due to GSV reflux, and the therapeutic effects analyzed. MATERIAL AND METHOD: Between September 2003 and February 2006, 238 patients (332 cases) with GSV reflux underwent endovenous laser treatment with a 980-nm diode laser. Operative procedures were simultaneous endovenous laser treatment and ambulatory phlebectomy. The preoperative clinical findings, postoperative complications and postoperative duplex US follow up results at 1 and 3 months were reviewed. RESULT: Postoperative complications were ecchymosis in almost cases, paresthesia 68 cases (20.5%) and skin burn in 3 cases (0.9%). Follow up duplex US revealed 26 and 10 cases at 1 and 3 months of GSV reflux or partial recanalization, with therapeutic success rates of 91.3 and 87.9%, respectively. CONCLUSION: The treatment of GSV occlusion with an endovenous laser is less invasive than traditional GSV stripping, but relatively high recanalization was experienced, possibly due to inadequate laser power, laser fiber pullback speed or an extremely dilated GSV. However, continuous attempts will be required to reduce the recanalization after the procedure, with accurate follow up using duplex US.

Thoracoscopic Repair of a Right-sided Congenital Diaphragmatic Hernia: A case report / 대한흉부외과학회지

A congenital diaphragmatic hernia, which mainly occurs in the left thorax, requires an emergency operative procedure during the neonatal periods. A right-sided congenital diaphragmatic hernia is rare, and often detected after the neonatal period due to the mild symptoms. Traditionally, the treatment repairs the diaphragmatic defect via a thoracotomy. However, good results of thoracoscopic repairs have been reported. Herein, the case of a 5-month-old girl, who received a thoracoscopic repair of a right-sided congenital diaphragmatic hernia, is reported.

Surgical Treatment of Femoral & Popliteal Arteries Thrombosis Caused by Collagen Material Closure Device: A case report / 대한흉부외과학회지

Manual or mechanical compression followed by 4 to 8 hours of bed rest is still the standard technique for accessing site management of the femoral arterial puncture site. But these methods are often uncomfortable and delay hospital discharge. Recently, a number of new devices to achieve hemostasis have been developed. These devices uses collagen to facilitate local hemostasis. But many complications associated with the use these devices have been reported internationally. We present a case of successful treatment of Rt. femoral and Rt. popliteal arteries thrombosis caused by Angioseal.

A Case of Intrapulmonary Solitary Fibrous Tumor: A case report / 대한흉부외과학회지

Solitary fibrous tumor is an uncommon submesothelial mesenchymal neoplasm that arises primarily from the pleura. Extrapleural solitary fibrous tumors are rare. Solitary Fibrous tumors are often asymptomatic and discovered incidentally but may become symptomatic when vital structures are involved or they grow large. In general, solitary fibrous tumor is diagnosed on the basis of radiologic findings and its histologic features, with immunohistochemistry serving to support the diagnosis. Most solitary fibrous tumors pursue a benign course, and the single most important predictor of clinical outcome is the ability to excise the entire lesion. We experienced a case of intrapulmonary solitary tumor arising from the right lower lobe which was treated with wedge resection. We report this case of the patient.

A Case of Pulmonary Langerhans Cell Histiocytosis associated with Central Diabetes Insipidus in Adult: A case report / 대한흉부외과학회지

Langerhans Cell Histiocytosis (LCH) is a pathologic proliferation and infiltration of various organs by Langerhans' cells of unknown cause. Incidence rate of one million parties 3~4 is seen in young child but the incidence is not sure in adult. Organ systems involved by LCH may include skin, ear, bone marrow, liver, spleen, lung, pituitary gland-hypothalamus and GI tracts. In case pituitary-hypothalamus axis are involved, diabetes insipidus happened. Primary Pulmonary Langerhans Cell Histiocytosis(PLCH) with uninvolvement of other organs is rare and accompanied diabetes insipidus is more rare. There are many cases of LCH with diabetes insipidus involve such as central nervous system except lung. PLCH accompany central diabetes insipidus is only 1 case. We report a case of PLCH that accompany central diabetes insipidus with literature investigation inDepartment of Thoracic and Cardiovascular Surgery, Hallym University.

Combined Large Cell Neuroendocrine Carcinoma with Component of Adenocarcinoma: A case report / 대한흉부외과학회지

Combined large cell neuroendocrine carcinoma is an uncommon lung cancer that include large cell neuroendocrine carcinoma with components of adenocarcinoma, squamous cell carcinoma, giant cell carcinoma and/or spindle cell carcinoma histologically. We report a case that pathologically diagnosed as combined large cell neuroendocrine carcinoma with component of adenocarcinoma after right pneumonectomy and mediastinal lymph node dissection. A 44-year-old man with intermittent chest pain was referred to our hospital for lung mass on the right mid lung field.
