The authors report a case of thoracic outlet syndrome in left side. Thoracic outlet syndrome is a collective term in which symptoms and signs are due to bony and soft tissue compression of the neurovascular bundle at the thoracic outlet. It is a rare case in neurosurgical field. So we had experienced one case of thoracic outlet syndrome which was improved by transaxillary approach for resection of first rib. The clinical features, diagnostic test, radiological findings, and operative technique are presented with review of literatures.

Stellate ganglion block (SGB) is applicated frequently to increase the blood flow and to reduce the pain in head, neck and upper extremity. The effects of SGB are able to be estimated by clinical signs and symptoms of Horner's syndrome, skin warmth, anhydrosis, etc. The effects are also estimated by sympathetic function and the blood flow. Blood flow velocities and pulsatility indices of common carotid,d axillary, brachial and radial artery were measured by Doppler flowmeter after SGB with 1% lidocaine at C6 level. Blood velocities of all arteries were increased and pulsatility indices of all arteries were decreased. This results suggest that SGB increase the blood flow of head and upper extremity and Doppler flowmeter is a good indicator of the effects of SGB.

Since thoracoscopy was originally described by Jacobaeus in 1922, video-assisted thoracic surgery has been used to treat many thoracic diseases. From June 1994 to July 1995, 35 patients with spontaneous pneumothorax'underwent video-assisted thoracic sugery as experimental group, and same number of patien:s with blob resection through mid-axillary thoracotomy as co trol group in our hospital.'The authors compared the clinical results between each group. 1. The sex distributions were 28 males, 7 females in experimental group and 30 males, 5 females in control group. The mean age of experimental group was 28.5 $\pm$ 12.6 years of age and that of control group was 2).9 $\pm$ 6.3 years of age. 2. The operative times were 98.8$\pm$ )9.3 minutes in experimental group and 103.6$\pm$ )2.6 minutes in control group. ). The duration of chest tube indwelling at postoperative period was 2.60 $\pm$ 0.98 days in experimental group, 4.80 $\pm$ 2.08 days in control group (P< 0.01). The periods of postoperative hospitalization were 17 $\pm$ 1.22 days in experimental group and 6.69 $\pm$2.52 days in control group. The durations of post-oper- ative chest tube indwelling and hospital stay in experimental group were shorter than in control group (P< 0.01 respectively). 4. The injection of analgesics at postoperative period was less in experimental group than control group. At the operative day and postoperative 1 st and 2nd day, the number of injections were respectively 1. 57$\pm$0.74, 1.97 $\pm$0.70 and 1.00$\pm$0.68 times/person in experimental group, 2.23 $\pm$0.60, 2.60 $\pm$0.67 and 2. 17$\pm$0.76 times/person in control group(P<0.01 respectively). The mean duration and dose of postoperative analgesic injection were 2.48$\pm$ 1.01 days/person and 4.88 $\pm$3.70 ampules/person in experimetal group, 3.70$\pm$ 1.40 days/person and 8.94 $\pm$4.21 ampules/person respectively (P< 0.01, p<0. 01).

Purpose : To evaluate our experience in the breast-conserving treatment for early breast cancer with special regard to recurrence Pattern and related risk factors. Materials and Method :Two hundred and sixteen patients with AJC stage 1and 11 breast cancer who received breast conserving treatment between January 1991 and December 1994 were evaluated A9e distribution ranged from 23-80 year old with a median a9e of 44. One hundred and seventeen Patients had 71 lesions and 99 Patients had 72 lesions. Axillary lymph nodes were involved in 73 patients. All patients received a breast conserving surgery (wide excision to quadrantectomy) and axillary node dissection followed by radiotherapy. Ninety six patients received chemotherapy before or after radiotherapy. Results : During the follow-up period (3-60 months, median 30 months), local recurrences were noted in six Patients (true: 3, elsewhere; 1, skin: 2). Sixteen patients developed distant metastases as the first sign of recurrence at 8-38 months (median 20 months) after surgery. Among them, three patients simultaneously developed local recurrence with distant metastases. Contralateral breast cancer developed in one Patient and non-mammary cancers developed in three patients. The actuarial 5 year survival rate was $88.4\%\;(stage\;I\;96.7\%,\;stage\;IIa\;95.2\%,\;stage\;IIb\;69.9\%)$. Age, I stage, number of involved axillary lymph nodes. and AJC stage were risk factors for distant metastases in univariate analysis. In the multivariate analysis, the number of involved axillary lymph nodes was the most significant risk factor for metastases. Conclusion : Local recurrence was not common in the early years after radiotherapy. Distant metastases occurred at a steady rate during the first three years and was more common in the Patients with larger tumors, higher number of involved axillary nodes, and younger age.

Purpose: In the breast cancer patient, lymphatic mapping and sentinel lymph node biopsy are the most important procedure for axillary lymph node staging. We aimed to compare the three radiocolloids [$^{99m}Tc$-antimony trisulfide colloid (ASC), $^{99m}Tc$-tin colloid (TC), and $^{99m}Tc$-human serum albumin (HSA)] for sentinel lymph node mapping. Subjects and Methods: Totally, 397 patients with clinically N0 stage were enrolled. $^{99m}Tc$-ASC was injected in 202 out of 397 patients, $^{99m}Tc$-TC was injected in 120 patients, and $^{99m}Tc$-HSA was injected in the remaining 75 patients. The sentinel lymph nodes were localized by lymphoscintigraphy and selected using intraoperative gamma probe. All sentinel lymph nodes were investigated by intraoperative pathologic consultation. The axillary lymph nodes which were harvested by the lymph node dissection were also investigated. Results: The patients of each group showed similar clinical characteristics. There were no significant differences (p>0.05) in the identification rate of sentinel lymph nodes (IR), false negative rate (FNR), and negative predictive value (NPV). The axillary lymphadenectomy revealed axillary lymph node metastases in those three groups (ASC-33.2%, TC-31.7%, HSA-22.7%). The IR, FNR, and NPV were not significantly different among those groups. Conclusion: Those three $^{99m}Tc$-labeled radiocolloids showed equivalent results in sentinel lymph node mapping of breast cancer.

Purpose: Lymphoscintigraphy and sentinel node biopsy has become a standard method for detection of axillary lymph node metastasis in breast cancer patients, but the standard radiopharmaceutical was not prepared. About detection of axillary lymph node metastasis by lymphoscintigraphy and sentinel node biopsy in breast cancer patient, we compared the results of Tc-99m Tin-colloid and Tc-99m Phytate by subareolar injection. Materials and Methods: This study included 382 breast cancer patients who were performed operation during 2001-2008. Three hundred forty nine patients was injected 0.8ml of Tc-99m Tin-colloid (37-185 MBq) by subareolar injection. Thirty three patients was injected 0.8ml of Tc-99m Phytate (37-185 MBq). Lymphoscintigraphy was performed in supine position and sentinel node localization was performed by hand-held gamma probe in operation. Result: Among 349 patients by Tc-99m Tin-colloid, 312 cases (89.4%) localized the sentinel node by lymphoscintigraphy, 304 cases (87.1%) localized by gamma probe. Among 33 patients by Tc-99m Phytate, 32 cases (97.0%) localized by lymphoscintigraphy, 33 cases (100%) localized by gamma probe. Detection rate by lymphoscintigraphy and gamma probe was superior for Tc-99m Phytate compared to that with Tc-99m Tin-colloid, with a statistically significant difference. (p<0.05, p<0.05) Conclusion: Tc-99m Phytate is a better choice for localization of sentinel node than Tc-99m Tin-colloid in breast cancer patients.

Purpose : To assess the locoregional recurrence rate, survival rate and prognostic factors after modified radical mastectomy and postoperative adjuvant radiation therapy with or with chemotherapy in high-risk breast cancer patients. Methods : Between $1984\~1995$, 48 patients underwent postoperative irradiation to the regional lymphatics and chest wall due to large tumor size $(\geq5\;cm)$ or small tumor size (<5 cm) with axillary lymph node involvement after modified radical mastectomy. The median age of the patients was 47 years (range, $31\~79\;years$). The clinical tumor size was <2 cm in 1 patient, $2\~5\;cm$ in 15 patients, and >5 cm in 32 patients. Thirty two patients had positive axillary lymph nodes. Forty two patients were irradiated to the chest wall and regional lymph node and 6 patients were irradiated in the chest wall only. Radiation dose to the chest wall and regional lymph node was 5040 cGy/28 fraction. The median follow-up time was 61 months. Results : Locoregional recurrence rate was $8\%$ and distant metastatic rate was $14\%$. The actuarial overall survival rate and disease-free survival rate was $53\%\;and\;62\%$ at 5 years, respectively. The median survival time was 57 months. Five-year overall survival rate by the stage is $70\%$ in IIB and $58\%$ in IIA. The significant prognostic factor for survival on multivariate analysis was the stage. Conclusion : Postoperative adjuvant radiation therapy in high-risk breast cancer can reduce the locoregional recurrence rate and increase the survival time by combined chemotherapy. The significant prognostic factor for survival rate was the stage.

Video-assisted thoracic surgery(VATS) is emerging as a viable alternative to thoracotomy when surgical treatment of spontaneous pneumothorax is required. 20 patients with spontaneous pneumothorax underwent bullectomy between July 1995 and May 1996. The patients were divided into two groups : Control group ; the patients who received with mid-axillary approach(n=10), Experimental group ; the patients who received with VATS (n=10). The results were as follows ; 1. The total sex distribution was male predominance (male:female=17:3). Mean age of control group was 29.6$\pm$9.8 years and experimental group was 27.2$\pm$11.9 years. 2. The mean period of postoperative chest tube indwelling duration and hospital stay were 3.3$\pm$0.8 days and 7.9$\pm$1.2 days in control group and 2.1$\pm$0.9 days and 5.2$\pm$3.1 days in experimental group(p=0.005 and p=0.02). 3. The mean time of operation, vital signs and arterial blood gas analysis did not showed any statistical differences between the groups. 4. Percent recovery of tidal volume and forced vital capacity were significantly improved in experimental group comparing with control group (p<0.05). 5. The patients undergoing VATS experienced significantly less postoperative pain and limitation of motion. In conclusion, VATS is safe and offers the potential benefits of shorter postoperative hospital stays and less pain with cosmetic benefits.
