Microsurgical techniques have developed numerous territories suitable for free tissue transfer. However, there are so many flaps in plastic and reconstructive surgical field, so no one dare to say which flap is the best. The radiovolar area of the forearm constitutes a versatile source for composite tissue free flap reconstruction for many areas of the body. The skin is thin and relatively hairless, and the vascular pedicle is long and large caliber The flap can be harvested conjunction with tendons and bone. The skin can be reliably reinnervated. We have used 32 radial forearm free flaps to reconstruct defect in various areas of the body resulting from tumor ablation, postburn scar contracture and penile amputation injury. We had two flap failures, one developed necrosis from venous thrombus formation, the other from the infection due to sepsis. Thirty of the 32 flaps survived completely. Overall survival rate was 94%. The donor sites have been relatively inconspicuous.

PURPOSE: We studied a clinical analysis of pediatric patients who visited the emergency medical center of Yeungnam University Hospital to compare the characteristics of pediatric emergency patients after year 2000 with the previous studies. METHODS: We reviewed 7, 034 children under the age of 15 years who visited the emergency medical center of Yeungnam University Hospital during the 2 year period from January 2001 to December 2002, and then we performed a clinical and statistical analysis. We analyzed the pediatric patients according to gender, age, season, day of the week, time of the visit, the disease classification and the final disposition of the patients. RESULTS: Among the patients who visited the emergency room, 15.6% of the total emergency patients were under the age of 15. The male to female ratio was 1.6: 1. Among the 7, 034 pediatric patients, the most common age group was between 1 year and under 3 years of age (26.9%). The peak seasonal incidence was early summer and spring, especially during June (11.2%) and May (10.6 %). The peak incidence day of the week was Sunday (24.8%) and the peak time when the emergency pediatric patients visited the emergency room was between 20 and 24 o'clock (28.8%). The distribution of diseases, according to ICD-10 system, were injury and poisoning (30.4%), diseases of the respiratory system (22.8%), and diseases of the digestive system (14.6%). 30% of total pediatric patients were admitted to the hospital. CONCLUSION: After year 2000, as compared with the previous studies, the proportions of emergency pediatric patients has decreased. The distribution of diseases was not much different from the previous studies and the proportions of non-urgent diseases, such as acute nasopharyngitis or acute gastroenteritis, were still high. These result have come about due to the declining birth rate and changes of the medical system in Korea.

Myxofibrosarcoma represents one of the most common soft tissue sarcomas of the extremities in adult and elderly patients. However, it only rarely occurs in the chest wall. A 58 years old woman presented with a huge painless lump (8x6.5 cm) in the right lower parasternal area which recurred a few months following excision from General surgery of our hospital. Histology showed an infiltrative deep seated dermal and subcutaneous tumor. It had a distinctive lobular growth pattern with prominent myxoid change and moderate cellularity. Tumor cells were spindle-shaped with varying degrees of pleomorphism and frequent mitotic figures. Numerous blood vessels with curvilinear growth pattern were also seen. Immunostains for S-100, CD68, Mac 387, and FX IIIa were all negative, but positive for Vimentin. The histologic feature was of an intermediate grade myxofibrosarcoma. Wide excision was performed and recovered in good condition without any physical disabilities and was discharged at one month later. Currently she is waiting for the skin graft without chemotherapy and radiotherapy.

BACKGROUND: The Y-composite graft of internal thoracic artery and radial artery is commonly used in coronary bypass surgery. The aim of this study is to look for a way to raise the free flow of the internal thoracic graft and to see flow dynamics of the Y-graft. MATERIAL AND METHOD: In 15 patients undergoing coronary bypass surgery, free flow of the in-situ internal thoracic artery graft was measured using two different papaverine application methods; extraluminal papaverine spray in 7 patients and intraluminal papaverine injection in 8. In 18 other patients for whom the Y-graft was used, total free flow and flow changes from the two ends were measured. RESULT: The free flow of the in-situ internal thoracic artery graft almost doubled with internal papaverine injection than with external papaverine spray (47.7+/-9.6 mL/min vs. 100.8+/-26.3 mL/min, p<0.001). Total flow of the Y-composite graft was significantly more than either flow of the internal thoracic artery end or radial artery graft end (173.3+/-45.3 mL/min vs. 121.1+/-34.3 mL/min or 117.5+/-42.8 mL/min). When both ends of the Y-composite graft were opened, free flows from the two ends were similar (85.4+/-27.8 mL/min vs. 87.9+/-42.4 mL/min, p=0.772). The flow of one end of the Y-composite graft was increased significantly by clamping of the other-end than when both ends were opened. CONCLUSION: Intraluminal papaverine injection is very effective in raising free flow of the internal thoracic artery graft, and the free flow of the Y-composite graft of in-situ internal thoracic artery and free radial artery graft is more than that of the in-situ internal thoracic artery graft. The flow of one end flow of the Y-graft may be altered by the flow change of the other end.

BACKGROUND: Preoperative elevated serum creatinine values are associated with increased risk for both morbidity and mortality in patients undergoing on-pump coronary artery bypass surgery (CABG). We investigated the postoperative changes of renal function and proper management in the patients. MATERIAL AND METHOD: Among 74 consecutive patients who underwent isolated on-pump CABG, 17 patients with increased serum creatinine level (creatinine > or = 1.5 mg/dL) within preoperative one week were included in the study. Seven patients showed preoperative serum creatinine level of 2.0 mg/dL or higher, and 3 of them had been undergoing hemodialysis. Preoperative hemodialysis was performed in the 3 patients due to end-stage renal failure (ESRD) the day before the operation. We started peritoneal dialysis immediately after the cardiopulmonary bypass in patients with ESRD or postoperative acute renal failure if it was necessary to remove intravascular volume and lower serum creatinine level. RESULT: In most of the patients with CABG, postoperative serum creatinine level increased and recovered to the preoperative level at the discharge. In 2 of the 4 patients with serum creatinine level of 2.0 mg/dL or higher and 3 patients with ESRD, intravascular volume, serum creatinine level and serum electrolyte were controlled with peritoneal dialysis. CONCLUSION: Postoperative serum creatinine level increased transiently in most of CABG patients, and intravascular volume and serum creatinine level were controlled by peritoneal dialysis only in the patients with acute renal failure postoperatively and those depending on hemodialysis.

BACKGROUND: Retrospective study was carried out on patients with primary spontaneous pneumothorax with the aim of determining if conventional thoracoscopic wedge resection is superior to modified transaxillary minithoracotomy with thoracoscopy in the surgical treatment. MATERIALS AND METHOD: 160 patients, aged 14 to 35 years with primary spontaneous pneumothorax were involved in this study. Patients were assigned to two groups by surgical technique; Conventional thoracoscopic wedge resection (group A; n=80) and modified transaxillary minithoracotomy with thoracoscopy (group B; n=80). Apical pleural abrasion & talc poudrage were performed in all cases. This study evaluated the following factors: duration of operation, days of analgesics used after operation, number of no air leak on the first postoperative day, duration of indwelling chest tube, hospital stay, postoperative complications, chronic chest pain (during follow-up) and resumption of normal activity. Relapses (ipsilateral recurrence after discharge) during follow-up periods were evaluated. RESULT: No significant differences were found in any of the factors studied in either group. CONCLUSION: Conventional thoracoscopic wedge resection and modified transaxillary minithoracotomy with thoracoscopy offer similar results in the surgical treatment of primary spontaneous pneumothorax. The rate of complication is low and the level of pain is acceptable without long-term sequele. Therefore, modified transaxillary minithoracotomy with thoracoscopy method appears as a valuable alternative surgical technique.

BACKGROUND: Female sex was known to be a risk factor for mortality after coronary bypass grafting (CABG), and women showed higher in-hospital mortality than men. MATERIAL AND METHOD: Between 1992 and 1996, 147 consecutive patients (98 men and 49 women) undergoing CABG were included in the study. Most patients had undergone CABG with left internal thoracic artery and saphenous vein under cardiopulmonary bypass. We examined the influence of gender on survival after CABG and looked for risk factors for survival. RESULT: There was no in-hospital mortality in women, but 3 death (3.0%) in men. During the mean follow-up period of 138.5+/-23.0 months, mortality was lower in women than in men (20.4% vs 44.9%, p=0.004), and the most common cause of death in women was chronic renal failure (40%). Survival in women at 1, 5, 10, and 14 years was 100%, 98.0+/-2.0%, 81.2+/-5.6%, and 78.4+/-6.1%, respectively, which was better than in men (p=0.004). Although preoperative left ventricular ejection fraction was higher in women than in men, this did not affect early and long-term survival difference between two sexes (p=0.15). Risk factor for long-term survival in women was diabetes (p=0.033) and in men number of diseased coronary artery (p=0.006). CONCLUSION: Long-term survival after CABG was better in women than men. Risk factor for long-term survival in women was morbid disease rather than cardiac disease.

From 39 eyes of 31 cases which received the cataract operation performed under the surface anesthesia by 2 specialists, 2 senior, 1 third and 1 first year residents at Red cross Society, the following results were obtained. 1. The maximal value of intraocular pressure was 19.0mmHg, minimal value, 11.5mmHg and the average, 14.9mmHg just before the cataract operation. 2. The rupture of the capsule was 21.4% and the loss of vitreous body, 7.1% in intraocular lens extrations. 3. The degree of anteior projetion of the eyes had not direct relationship with the intracapsular lens extraction. 4. All patients who received the cataract operation were required sufficient akinesia sedation. 5. Within normal intraocular pressure, the intraocular pressure didn't seem to have any effect to the loss of vitreous body.

Tailoring thoracoplasty is employed prior to, following, or concomitant with pulmonary resection when it is anticipated that insufHclent lung tissue will remain to fill the pleural space following a pulmonary resection. This study reviewed a series of eight patients treated with tailoring thoracoplasty between 1990 and 1995. Indications were to close a persistent space In four patients and to tailor the thoracic cavity to accept diminished lung volume concomitant with a pulmonary resection in the other four patients. The primary underlying disease was lung cancer in three patients and pulmonary tuberculosis In five patients, two of whom had concomitant aspcrgilloma, two, pneumothora, and one, empyema with bronchopleural fistula. In four patients with a prior pulmonary resection, the tailoring thoracoplasty was performed within eight days after the resection surgery. There was no failure to accommodate the thoracic cavity to insufficient lung tissue, even though two patients needed a second thoracoplasty. We conclude that tailoring thoracoplasty may be performed to close anticipated persistent pleural space and to accommodate diminished lung volume with acceptable cosmetic results Early, after, or concomitant with pulmonary resection in selected patients.
