The author reviewed 263 cases of pulmonary tuberculosis operated on at the Department of Thoracic Surgery, Seoul National University Hospital during the 19 year period, from January, 1957 to December 1975. Following observations were made: 1) The sex ratio was 2.8: 1 in male's favor, and 83.6% of the patients were between 20 and 49 years of age. 2) The trends in operative procedures revealed that surgical collapse as a definitive therapy of pulmonary tuberculosis has virtually disappeared and operations required for residuals of pleural diseases have increased. 3) The overall hospital mortality rate was 3-8%. The highest mortality rate was encountered in the cases of resection and decortication with 28.6%, 4) The rate of overall postoperative complications was 24.7%, the highest being encountered in decortication with 56.4%. 5) The most frequent cause of death was bleeding, while the dead space was the most frequent complication.

We report a case of recurrent dermatofibrosarcoma in a 30-years-old woman who had undergone operations three times during 60 months and had received post-operative radiotherapy. On neurological examination, no neurological deficits were noticed. In brain magnetic resonance image(MRI), there was right parieto-occipital scalp mass with high signal in T2-weighted image, low signal in T1-weighted image with homogeneous enhancement. The removal was done including about 2cm uninvolved margins and pathologic examination of the lesion revealed dermatofibrosarcoma protuberans(DFSP). The prognostic factors of local recurrence may be related to surgical margins for resection; the length from the grossly intact margins, and the microscopically controlled excision in margins.

Surgical repair of the tetralogy of Fallot is one of the most successful operations in the treatment of congenital heart diseases. We report the case of a 65-year-old man who had an aortic valve replacement at the time of complete repair of the tetralogy of Fallot at the age of forty-three. He subsequently had progressive aortic root and ascending aorta dilation to 9 cm. The aortic root and ascending aorta replacement was done using a composite valve-graft and was performed along with other procedures. Thus, meticulous follow-up of aortic root and ascending aorta after corrective surgery for tetralogy of Fallot is recommended following initial curative surgery.

Craniovertebral junction (CVJ) tuberculosis is a rare disease, potentially causing severe instability and neurological deficits. The authors present a case of CVJ tuberculosis with atlantoaxial dislocation and retropharyngeal abscess in a 28-year-old man with neck pain and quadriparesis. Radiological evaluations showed a widespread extradural lesion around the clivus, C1, and C2. Two stage operations with transoral decompression and posterior occipitocervical fusion were performed. The pathological findings confirmed the diagnosis of tuberculosis. Treatment options in CVJ tuberculosis are controversial without well-defined guidelines. But radical operation (anterior decompression and posterior fusion and fixation) is necessary in patient with neurological deficit due to cord compression, extensive bone destruction, and instability or dislocation. The diagnosis and treatment options are discussed.

We studied blood salvage effect of Cell Saver Apparatus[CSA with adult cardiac patients. This study compares blood salvage in two groups of patients undergoing valve replacement or congenital cardiac operation.Group 1 is composed with 60 patients operated during 1991-1992 using CSA. Group 2 is composed with 60 patients operated during 1990-1991. No special effort was made to salvage blood in Group 2. The average requirements in Group 1 were approximately one-fourth the amount of RBC products by Group 2. The hospital course, blood chemistry level were comparable for the two groups. CSA produced blood was concentrated, well oxygenated blood and the average amount was 830 ml. Any complication was not detected in transfusion of CSA produced blood. This study shows that CSA allows safe and practical blood salvage during adult cardiac operations.

Neuroendoscopic surgery is performed because it causes minimal damage to normal structures, carries a lower rate of complications, and achieves excellent outcomes. Surgeons using an endoscope and related instruments can perform complex operations through very small incisions, which is especially useful for minimally invasive procedures for the brain and spine. Neuroendoscopic surgery is now performed in cases of obstructive hydrocephalus, various intraventricular lesions, hypothalamic hamartomas, craniosynostosis, skull base tumors, and spinal lesions. This review discusses the brief history of neuroendoscopy and the current state and future perspectives of endoscopic surgery.

Most chordomas show extradural extension and bone destruction. A 32-year-old man presented with neck pain and progressive paraparesis. He had been diagnosed a clival chordoma and underwent an operation seven years ago. Radiological studies revealed that the tumor was recurred in a retroclival area and invaded into intradural region. We removed the tumor by two staged operations. After surgery, satisfactory results were achieved.

Subarachnoid pleural fistula (SPF) is an aberrant communication between the pleural cavity and subarachnoid space, resulting in uncontrolled cerebrospinal fluid drainage. The negative pressure of the pleural cavity creates a continuous suctioning effect, thereby impeding the spontaneous closure of these fistulas. Dural tears or punctures in cardiothoracic procedures, spinal operations, and trauma are known to cause such abnormal communications. Failure to recognize this entity may result in sudden neurological or respiratory complications. Hence, a high index of suspicion is required for early diagnosis and prompt management. Noninvasive positive pressure ventilation has been described to be effective in managing such fistulas, thus mitigating the high morbidity associated with exploratory surgery for primary repair. Herein, we describe the typical presentation of SPF and the clinical course, treatment, and follow-up of a patient who sustained SPF following anterior thoracic spinal surgery.

Pheochromocytoma (PCC) is a neuroendocrine tumor that mainly arises from the medulla of the adrenal gland. Some PCCs become malignant and metastasize to other organs. For example, it typically involves skeletal system, liver, lung, and regional lymph nodes. However, only a few cases of PCC with brain metastasis have been reported worldwide. We report a case of metastatic brain tumor from PCC in South Korea in 2016. A 52-year-old man presented with headache, dizziness and motor aphasia. He had a medical history of PCC with multi-organ metastasis, previously underwent several operations, and was treated with chemotherapy and radiotherapy. Brain MRIs showed a brain tumor on the left parietal lobe. Postoperative pathology confirmed that the metastatic brain tumor derived from malignant PCC. This is the first report PCC with brain metastasis in South Korea.
