Twenty-six patients (12 male and 14 female) with symptomatic scapular winging caused by serratus anterior dysfunction were managed with split pectoralis major tendon transfer (sternal head) with autogenous hamstring tendon augmentation from 1998 to 2006. Twenty-five patients had positive results for long thoracic nerve palsy on electromyography. The mean duration of symptoms until surgery was 48 months (range 12~120 months). Four patients had non-traumatic etiologies and twenty-two patients had traumatic etiologies. At the final follow-up assessment for functional improvement, a Constant-Murley score was used. 21 patients were completely evaluated, while 5 patients who had less than 12 months follow-up were excluded. Pain relief was achieved in 19 of the 21 patients, with twenty patients showing functional improvement. The pain scores improved from 6.0 preoperatively to 1.8 postoperatively. The mean active forward elevation improved from $108^{\circ}$ (range $20^{\circ}\sim165^{\circ}$) preoperatively to $151^{\circ}$ (range $125^{\circ}\sim170^{\circ}$) postoperatively. The mean Constant-Murley score improved from 57.7 (range 21~86) preoperatively to 86.9 (range 42~98) postoperatively. A recurrence developed in one patient. Of the twenty-one patients, eight had excellent results, nine had good results, three had fair results, and one had poor results. Most patients with severe symptomatic scapular winging had functional improvement and pain relief with resolution of scapular winging.

Forty eight patients diagnosed as atrial septal defect, had been operated from April 1986 to December 1990 at the Department of Thoracic and Cardiovascular Surgery, Inha University Hospital, were analysed retrospectively. Of the 48 patients, 12 patients, were male and 36 patients were female, Their ranged from 8 months to 51 years old, and the mean was 18.0 years old. The proceeding two symptoms were exertional dyspnea and frequent upper respiratory infection. But 10 patients [20.8%] were asymptomatic. Electrocardiographic findings were regular sinus rhythm in 100.0%, RVH in 29.2%, incomplete RBBB in 27.1%, and first degree AV block in 2.1%. Hemodynamic studies were performed in 38 of 48 patients. Significant pulmonary hypertension[over 50mmHg in systolic pulmonary arterial pressure], which is the most serious risk factor, was developed in 4 patients[8.3%]. There was statistical significance between size of defect[cm2/BSA-M2] and systolic pulmonary arterial pressure[sPAP] retrospectively[p=0.036]. We could not find the correlationship between age and Qs % size. Anatomically, secundum type constituted 97.9%, in which 43 patients were PFO type[91.6%] and 3 patients were IVC type[6.3%]. 38 of 48 ASD patients were repaired with patch closure[72.9%] and remains were repaired with direct closure[27.1%]. The operative result was excellent except two cases of transient postoperative arrhythmia. There was no operative mortality.

A Total of Forty eight patients underwent open-heart surgery for correction of tetralogy of Fallot at the Seoul National University Hospital from January 1974 to October 1976, with an overall survival rate of 77 per cent. Operative mortality varied according to severity of the lesion, age of the patient, nature of previous surgical treatment and presence or absence of an outflow tract patch across the pulmonary valve ring. Eleven patients died in the early postoperative period and thirty seven patients were discharged from the hospital alive. A patch of the right ventricular outflow tract and pulmonary annulus was required to relieve pulmonic stenosis in 24 patients. There were 10 deaths in this group (42%) as compared to 1 death in the group of 24 patients who were corrected without a patch. Operative mortality was especially higher when an inlay patch was placed across the pulmonary valve ring. This may be related to the possibly greater anatomic severity of these cases and to the longer operating time when a patch was used. The electrocardiogram showed right ventricular hypertrophy in 35 cyanotic patients. Intraventricular conduction was normal in 34 patients before operation. It was normal postoperatively in only 5 of 34 patients in this group who survived surgery. Complete right bundle branch block appeared at operation in 21 patients, and 8 patients developed incomplete right bundle branch block. Major causes of death were progressive cardiac failure (4), Complete atrioventricular dissociation (3), bleeding (2), cardiac tamponade (1), and sudden cardiac arrest (1)

In this study, the authors analyzed the prognostic value of four clinical variables[age and sex of patients, association with myasthenia gravis and clinical stage] and histological type in 30 consecutive patients with thymoma, histologically classified as cortical[10],medullary[5] and mixed[15]type according to Marino and Muller-Hermelink classification. There were significant differences between the histological types in the frequency of the different tumor stages and myasthenia gravis and prognosis.Most of the cortical thymomas were at stage III and all of the medullary and most of the mixed tumors at stage I or II.Myasthenia gravis occurred more commonly in patients with cortical[30%] and mixed thymoma[60%] than in patients with medullary thymoma[10%]. Follow-up was conducted in 30 patients,with follow-up range from 3 months to 120 months[mean,47.3months]. 5 year actuarial survival was 100% for medullary thymoma, 73% for mixed thymoma, and 47% for cortical thymoma.The overall survival curve shows that 87.6% of the patients are alive at 2 years and 72.8% at 5 years. And 7 patients was dead during follow-up periods.By Kaplan-Meier technique, we found that the patients who had myasthenia gravis had better prognosis[P<0.05]. Medullary thymoma is a comparatively rare, benign tumor, and usually not associated with myasthenia gravis. Cortical thymoma must be regarded as malignant. Mixed thymoma is intermediate in its behavior between medullary and cortical thymoma. But these tumors should be considered potentially malignant despite of presence as stage I of II disease. Also, the patients with stageI,II had good prognosis and the patients with total resection had good prognosis[P<0.05].

Because patients with coronary artery disease (CAD) have depressed vagal modulation and the mortality risk from acute myocardial infarction is lower in patients with higher vagal modulation, methods that can increase vagal modulation are desirable in patients with CAD. We intended to inspect the effect of recumbent posture on vagal modulation. By using angiography, 33 patients with abnormal (CAD group) and 33 patients with normal coronary arteries (control group) were studied. The nonlinear as well as the linear characteristics of heart rate variability (HRV) were analyzed on these patients in three recumbent postures: namely, the supine, right lateral decubitus, and left lateral decubitus postures. The lower the normalized high-frequency power (nHF) in the supine or left lateral decubitus posture, the higher the increase in the nHF when the posture was changed from supine or left lateral decubitus to right lateral decubitus in both groups of patients. Right lateral decubitus posture can lead to the highest vagal modulation and the lowest sympathetic modulation among the three recumbent postures in both normal and patients with CAD. Therefore, the right lateral decubitus posture can be used as an effective physiologic vagal enhancer in patients with CAD.

From July 1975 to March 1984, 16 patients of complex congenital cardiovascular anomalies associated with left superior vena cava were seen at Han-Yang University Hospital. The age of patients was ranged from 2 to 15 years-old. The distribution of Sex was 7 patients in male, 9 patients in female. Persistent Left Superior Vena Cava [L.S.V.C.] was classified according to the proximal connection of L.S.V.C. into 3 groups. Group I which L.S.V.C. connected to coronary venous sinus was in 9 patients, Group II which L.S.V.C. connected to Left atrium was in 5 patients, Group III which L.S.V.C. hemodynamically connected to right atrium was in 2 patients. Pathoanatomical findings of complex congenital cardiovascular anomalies associated with L.S.V.C. in 16 cases were generally show unsystematic irregularity. In group I, A.S.D. were only in 3 cases, but in highest incidence and in group III, all two cases were supracardiac type of total anomalous drainage of pulmonary veins. Post-operatively, 3 patients among 14 patients of total correction, were died immediately, 1 patient of palliative shunt operation was died after 2 and half years, and Follow-up results of other remaining patients were excellent.

The experience with operative treatment for total correction of Fallot at the department of Thoracic and Cardiovascular Surgery, Keimyung University Dong San Medical Center from July 1980 to July 1984 was reviewed. There were 37 males and 12 females and their ages ranged from 3 years to 30 years, with the average age of 12.2 years. Sixty nine point four percent of patients were younger than 15 years of age. The most frequent type of right ventricular outflow stenosis was the combined type [pulmonary valvular and infundibular stenosis] containing 41 patients [83.7%] and there were 9 deaths in this group. The major associated lesions included Patent foramen ovale in 20 patients [40.8%], Atrial septal defect in 7 patients [14.3%], Left superior vena cava in 4 patients [8.2%], Right sided aortic arch in 2 patients [4.1%] and Patent ductus arteriosus in 11 patient [2.0%]. The pulmonary valvotomy was performed in 41 patients and patch graft reconstruction of the right ventricular outflow tract was performed in 23 patients. In 11 patients the monocusp patches were used. Thirty-five patients [71.4%] had the right bundle branch block postoperatively. There were 11 postoperative deaths with hospital mortality rate of 22.4% and the leading causes of death were low output syndrome, bleeding, and cerebral embolism.

Purpose: We analyzed the characteristics and differences in patients' medical benefits and health insurance based on disease severity classification. Methods: We examined 29,139 patients who visited the emergency medical center of K Hospital from January 1,2016 to December 31, 2016. Survey items included the Korean Triage and Acuity Scale (KTAS) classification of emergency and non-emergency situations ratio and type of insurance. Results: According to KTAS classification, 76.2% of patients exhibited an emergency condition and 23.8% exhibited a non-emergency condition. Emergency patients exhibited more trauma than non-emergency patients. According to the type of insurance coverage, the duration of stay in the emergency room was longer for patients with medical care than for patients with health insurance. Additionally, 119 ambulances use was significantly higher among patients with medical care. Conclusion: Policy discussions should address alternative ways to replace the 119 ambulances used by patients in this study. Additionally, health care administrators should identify alternative care agencies as potential alternatives to emergency room visits.

Objective : The goal of this study is to evaluate the clinical results in six patients who underwent surgical decompression for the acute subdural hematomas[ASDH] of posterior cranial fossa. Methods : Six patients [five males and one female] who had undergone surgery for ASDH of posterior cranial fossa between 2000 and 2005, were evaluated retrospectively with regard to clinicoradiological findings and surgical outcomes. The mean age was 45.8 years [range $9{\sim}67\;years$]. Results : Preoperative computed tomography showed ASDH on cerebellar hemisphere in four patients and on midline in two. All patients had the associated lesions such as subarachnoid hemorrhage, epidural or subdural hematoma, intraventricular hemorrhage, contusion or pneumocephalus in supratentorial area. Fracture of occipital bone was noted in two patients. Of the four patients who had 13 to 15 of Glasgow coma scale score at the time of admission, three were deteriorated within 24 hours after trauma. Of these three patients, delayed subdural hematoma developed 1 hour after initial normal CT finding in one patient and increased in thickness in another one. Postoperative outcome showed good recovery in three patients and moderate disability in one. Two patients were expired. Conclusion : This study supports that early diagnosis based on strict observation and prompt surgery in the patients with ASDH in posterior fossa will lead to the best results.
