Primary hemangiopericytoma of chest wall is very rate and only a few cases have ever been reported. The tumor aries from the capillary pericyte of Zimmerman. It is a highly vascular slow growing tumor which can be calssified as both malignant and benign varieties. We report a case of a 66 year-old man in whom recurrent hemangiopericytoma was treated by complete surgical excision. In October 1993 he had received surgical excision of hemangiopericytoma on posterior chest wall. For more than 6 years after the operation he was in good condition until a recurrent mass was found on the chest X-ray. The patient was discharged 9 days after the operation and is receiving radiotherapy.

Direct anterior approach for lesions located anterior to the thecal sac is definitely superior to lateral or posterior approach in many respects. However, various anatomical obstacles and technical difficulties often hinder direct anterior approach. Thanks to ripe experience of retroperitoneal approach to the lumbar spine for anterior lumbar interbody fusion and total disc replacement, the authors could perform lumbar corpectomy and reconstruction by using midline retroperitoneal approach recently. During this approach, we repaired anterior longitudinal ligament also to reduce the risk of graft extrusion and to prevent erosion of vascular wall due to direct contact between metallic hardware, which was used for reconstruction of vertebral body, and major vessels.

BACKGROUND: Congenital cystic diseases of the lung are uncommon but they share similar embryogenic and clinical characteristics. MATERIAL AND METHOD: From 1972 to 1999, 46 patients were operated on in the Dept. of Thoracic Surgery at the YUMC. And we analysed the patients' charts for clinical presentations, managements and pathologic findings with chart of patients. RESULT: There were 17 males and 29 females, and mean age was 16.2 years. The main symptoms were 11 fevers due to recurrent infection, 10 dyspneas, and chest pain and sputum production etc. Thirteen patients were asymptomatic. There were 13 pulmonary sequestrations(PS), 12 congenital cystic adenomatoid malformations(CCAM), 12 bronchogenic cysts(BC), 5 cystic bronchiectasis(CB) and 4 congenital lobar emphysemas(CLE). Simple excision(resection) was performed in 8 patients, segmentectomy in 6 patients, lobectomy (with 1 operative mortality) in 31 patients, and pneumonectomy in one patient. The compli-cations were 4 pneumonias, one persistent air leakage and one empyema. CONCLUSION: We experienced surgical treatment of congenital cystic lung disease and reported them with literature review.

Pulmonary endomertiosis is a rare disorder with the typical symptom of hemoptysis during menstruation (catamenial hemoptysis). We report a case of a 19-year-old woman, gravida 0, with 3-month history of catamenial hemoptysis which was confirmed with chest computed tomography. She was treated by means of thoracoscopic wedge resection for the right lesion and fuperior segmental resection through the left thoracotomy, successively. Preoperative fluoroscopy-guided hooking for thoracosopic target lwsion was helpful in circumstances with one lung anesthesia. Four months of follow-up after an uneventful discharge revealed out no recurrence of catamenial hemoptysis in symptoms and images.

The incidence of tuberculosis (Tbc) infection is high in some parts of the world and tuberculous cold abscess of the chest wall (CACW) often fails to respond to medical treatment. Medical records of 178 patients who underwent surgical treatment of chest wall abscesses from July 1970 to Sept. 2000 were reviewed and 89 patients who were pathologically confirmed as Tbc cold abscess cases were included in this study. Their ages ranged from 9 to 71 years (mean 33.3 years) and the male to female ratio was 1.2:1 (49 male, 40 female). The symptoms were palpable chest wall mass, pain and pus discharge, and three patients had multiple lesions. Twenty-five patients (28%) underwent excision of chest wall abscesses and 64 patients (72%) underwent chest wall and rib resection. Tbc medication was given preoperatively in 39 patients for an average of 6.3 months and all patients were given Tbc medication postoperatively for an average of 12 months. Postoperative complications were bleeding, pus discharge, empyema, pleural effusion, wound dehiscence, subcutaneous emphysema and activation of pulmonary Tbc. The disease recurred in 7 patients (7.8%) and these 7 patients all underwent a second operation. We recommend preoperative Tbc medication and complete resection of chest wall abscesses including any suspicious ribs. Postoperative Tbc medication for a minimum of 12 months is essential to decrease the risk of a relapse.

OBJECTIVE: The surgical outcome of anterior lumbar interbody fusion(ALIF) with pedicle screw fixation for elderly isthmic spondylolisthesis was analyzed. METHODS: Consecutive nineteen elderly patients (aged 65 years or more) with isthmic spondylolisthesis (Grade I or II) who underwent single level ALIF with pedicle screw fixation in 2002 were analyzed. Using clinical chart and mailed questionnaires, preoperative and postoperative Visual Analogue Scale(VAS) of back and leg pain and postoperative Macnab criteria were evaluated. RESULTS: The mean age at the time of operation was 68.4 years (range 65 to 78 years). Twelve patients underwent ALIF with percutaneous pedicle screw fixation. Seven patients underwent ALIF followed by posterior decompression and pedicle screw fixation. The postoperative complication rate was 10.5% (wound dehiscence in 1 patient and incisional hernia in 1 patient). There was no postoperative major morbidity or mortality. At a mean follow-up duration of 30.7 months (range 25 to 35 months), 93.3% (14/15) of the patients showed excellent or good outcomes in terms of Macnab criteria. The mean VAS scores of back pain and leg pain significantly decreased after surgery. CONCLUSION: ALIF with pedicle screw fixation yielded favorable results for elderly isthmic spondylolisthesis in selected cases.

The complications of the treatment of penile lesion are wide ranging, urethrocutaneous fistula being one of the less common. This complication affects the ventral aspect of the penis. We present a rare case of urethrocutaneous fistula after vaporization of penile lesion by CO2 Laser. One fistula was at ventral aspect of the penis. A 43-year-old male presented with passage of urine from one opening. He had undergone a vaporization by CO2 laser, 2 times. Urethrocutaneous fistula repairs was performed with biopsy of the edge of fistula site. Squamous cell carcinoma was confirmed. He subsequently underwent a partial penectomy. It is very important that biopsy was performed before vaporization of even small size skin lesion. This case is reported along with a brief review of the literature.

BACKGROUND: With mitral valvular heart disease, chronic atrial fibrillation(AF) is not likely to return to sinus rhythm after the operation. We evaluate the long term results and factors in recurrence of AF after modified Maze operation with mitral valve surgery. MATERIAL AND METHOD: From 1990 to 1996, 35 patients with chronic AF underwent modified Maze operation with mitral valve procedure in patients with chronic AF. The mean duration of AF was 7.7 +/-4.5 years. The concomitant operations were 34 mitral valve replacement(with 4 tricuspid annuloplasty and 3 tricuspid valve replacement)and 1 mitral valve repair. We analyzed the long term results and factors in recurrence of AF. RESULT: At immediate postoperatively, 33 of the 35 patients(93.9%) were converted to sinus rhythm. There was one operative death. However, AF recurred in 12 out of 35 patients during hospitalization and AF in these 12 patients were treated with antiarrhythmic drugs and electrical defibrillation 2-3 months later. Two out of twelve patients were failed in conversion to sinus rhythm after cessation of medication with side effects. During follow-up(71.1 +/-17.5 months, range 3-9 years), AF recurred in 9 patients and overall conversion rate to sinus rhythm was 73.5%. Predictors of postoperative AF included: duration of preoperative AF(maintenance group: recurrence group=6.3 years VS. 10.3 years, p=0.008) and cardiothoracic ratio on preoperative chest X-ray(0.58 VS. 0.72, p=0.009). CONCLUSION: AF surgery with mitral valve procedure increase the chance of recovery into sinus rhythm, reduce the incidence of atrial arrhythmia, and reduce the left atrial size with decreasing wall stress simultaneously. In order to decrease the incidence of postoperative arrhythmia, proper modification of the surgery with medical therapy should be considered.

The primary mediastinal liposarcoma is very rare and only a few cases have been reported. We report a 25 year-old man who have had coughing and mild fever for a month. The simple chest X-ray and computed tomography of the chest revealed a huge mass in the right thoracic cavity that originated in the anterior mediastinum. Cytologic examination of the needle aspiration biopsy confirmed the diagnosis of a primary mediastinal liposarcoma. Through an exploratory right thoracotomy and a median sternotomy, the huge mass, lobulated and about 2,500 gm in weight, was extirpated. Mass was attached to a portion of the pericardium and diaphragm, but there was no invasion or metastasis to pleura and lung. The patient was discharged on the 12th postoperative day. He is continuously receiving radiotherapy.

A 45-year-old man presented with lower back pain and pain in the right leg of 3years duration. A plain radiographic examination revealed grade I isthmic spondylolisthesis, with instability at L4-5. Computed tomography and magnetic resonance imaging demonstrated bilateral foraminal stenosis, with soft foraminal disc herniation on the right side at the L4-5 level. He underwent anterior lumbar interbody fusion(ALIF) with percutaneous posterior fixation(PF) at the L4-5 level. Without removing the posterior bony structures, removal of foraminal disc herniation and reduction of spondylolisthesis were successfully performed using ALIF with percutaneous PF. When there is no hard disc herniation or lateral recess stenosis, ALIF with percutaneous PF can be one of the treatment options for isthmic spondylolisthesis, even in the presence of foraminal disc herniation, as in our case.
