Between 1977 and 1987, 8 patients underwent excision of cardiac myxomas at the Hanyang University Hospital. All had a left atrial myxoma. There were 4 female and 4 male patients ranging from 15 to 62 years of age. Preoperative findings consist of symptoms and signs of congestive heart failure except one. Diagnosis was confirmed by echocardiography[8 cases] and angiography[2 cases], preoperatively. A biatrial operative approach was utilized in all but 2, who were small sized. Complete excision of the tumor with a cuff of normal tissue[1 was atrial wall and 7 were atrial septum] was performed. all heart chambers were carefully explored for presence of multicentric myxomas or tumor debris. There were no operative deaths or intraoperative embolization. Follow-up has been 1/3 to 10 years. There has been 1 late death, due to recurrence and 1 patient had reoperation for mitral regurgitation due to dilatation of the annulus by a huge tumor mass. Surgical excision of the myxoma can be performed with low morbidity, and it provides excellent and sustained symptomatic relief. The recurrence rate is low, but long-term follow-up and serial echocardiography are advisable.

Tracheobronchial rupture following tracheal intubation is a rare complication. We experienced a case of tracheal rupture following double-lumen endotracheal tube intubation. A 76 year old female was admitted due to coughing and chest discomfort. The operation was performed with the diagnosis of congenital broncho esophageal fistula. During the operation, accidently the main trachea was ruptured longitudinally. There was no history of surgical trauma. The ruptured trachea was repaired with prolene and monofilament absorbable sutures. The cause of tracheal rupture was suspected overinflation of the cuff. The patient was discharged from the hospital without any significant complications.

소절개 봉합술은 관혈적 봉합술에 비해 동반된 상완관절와 관절(glenohumeral joint)내의 병변을 확인하고 이에 대한 처치를 시행할 수 있으며, 견봉하 감압술과 함께 동반된 견봉 쇄골 관절의 병변을 치료할 수 있다. 또한 삼각근 기시부에 대한 손상을 최소화하기 때문에 마른 재활과 조기 퇴원을 시행할 수 있는 둥의 장점이 있다. 관절경적 봉합술에 비해서는 수술 술기가 어렵지 않기 때문에 항상 좋은 결과를 기대할 수 있다. 회전근개 파열에 대한 수술을 시행할 때 관절경적 봉합술이 모든 경우에서 관혈적 또는 소절개 봉합술에 비해 좋은 결과를 나타내는 것은 아니다. 환자가 심한 골다공증이 있는 경우, 기술적 문제가 있는 경우, 봉합후 회전근개에 지나친 긴장이 염려될 때는 항상 소절개 봉합술로의 전환을 시도하여야 한다. 소절개 봉합술을 시행한 경우에도 관절경적 봉합술시와 비슷한 좋은 결과를 얻을 수 있고, 치료의 결과는 수술의 종류보다는 정확한 술기 및 술전 환자의 상태에 좌우된다고 하겠다.

Calcific tendinitis of rotator cuff is a common disease which could be the cause of shoulder pain, and frequently occurs in supraspinatus, infraspinatus and teres minor in descending order. Calcific tendinitis of subscapularis is rare and arthroscopic treatment of that has also been rarely reported. So, we report a case of arthroscopic treatment of calcific tendinitis of subscapularis with excellent result.

견관절의 ABER position에서 posterosuperior rotator cuff 가 posterior glenoid에 contact 하여 internal impingement가 일어나는 현상은 운동선수가 아닌 일반인에게도 발생하는 physiologic phenomenon이며 과도한 반복 동작으로 인하여 증상이 발현한다. Internal impingement는 증상이 모호할 뿐만 아니라 견관절 내 여러 병소가 함께 존재하기 때문에 각각의 pathology에 대한 자세하고 정확한 evaluation이 필수적이다. 아직 controversy가 있지만 internal impingement의 pathologic factors로서는 anterior capsular laxity (true anterior laxity), posteroinferior capsular tightness (pseudo anterior laxity)와 이로 인한 glenohumeral internal rotation deficit (GIRD), 그리고 SICK scapula syndrome (scapular dyskinesis) 등으로 요약할 수 있다. 진단은 주로 병력 청취와 신체 검사로 내려지며 ultrasonogram, MRA등으로 확진한다. Sleeper stretching exercise 등과 같은 보존적 치료에 반응이 좋지만 6개월간의 재활 치료에도 호전이 없다면 증상과 직접 관련된 주 병소(appropriate pathology)를 찾아 이에 대한 적절한 수술이 이루어져야 한다.

Traumatic anterior dislocation of the shoulder is one of the most common directions of instability following a traumatic event. Although the incidence of shoulder dislocation is similar between young and elderly patients, most studies have traditionally focused on young patients due to relatively high rates of recurrent dislocations in this population. However, shoulder dislocations in older patients also require careful evaluation and treatment selection because they can lead to persistent pain and disability due to rotator cuff tears and nerve injuries. This article provides an overview of the nature and pathology of acute primary anterior shoulder dislocation, widely accepted management modalities, and differences in treatment for young and elderly patients.

Tracheoesophageal fistula[TEF] is a rare but life-threatening lesion that may occur from ventilation with a cuffed tube. It occurs most frequently when an inlying esophageal tube is also being used-usually for feeding purposes. The mechanism of injury appears to be pressure experted on the tracheal wall by the cuff, which then compresses the "party wall" of the trachea and esophagus against the foreign body that lies in the esophagus. The patient was 32 years old female who had been receiving a treatment of respiratory failure induced by postoperative sepsis with assist ventilator and nasogastric tubal feeding. Sudden attack of abdominal gas distention and massive drainage of gas through N-G tube were developed during assist ventilation in that patient, so we diagnosed as tracheal stenosis with a tracheoesophageal fistula induced by prolonged endotracheal intubation We performed tracheal reconstruction and primary closure of perforated esophagus after weaning ventilator. The postoperative course was uneventiful.eventiful.

This study describes an oscillometric-based blood pressure measuring algorithm by detecting turning points of oscillation signal from digitally filtered cuff signals of an automatic sphygmomanometer. The blood pressure measuring algorithm uses a characteristic ratios method from the turning points. The accurate values of the systolic/diastolic blood presures(SBP/DBP) are calculated using the peaks in the ranges of characteristic ratios. Performances of the proposed algorithm and four automatic sphygmomanometers are compared with the mercury manometer(manual type sphygmomanometer), regarding the SBP and DBP values of manual sphygmomanometer as the reference values. The performance test showed the proposed algorithm revealed the best results in errors and a statistical analysis. Therefore this algorithm can be usable in any automatic sphygmomanometers.ssure states. This may be compromising results for subject-independent sensibility evaluation using EEG signal.

회전근 개 부분 파열은 노화의 과정 중 생기는 무증상의 병변 또는 견관절 기능 장애의 잠재적인 원인으로 생각되었다. 발병 원인은 해부학적인 원인에 의한 충돌 또는 반복적 미세 외상 등이 원인으로 이해되고 있으며 병리생태에 관한 이해가 깊어지고 진단 기구, 즉 초음파나 자기공명영상, 관절경 등의 발달로 발생률이 과거에 비해 증가하고 있다. 그러나 회전근 개부분 파열은 질환 자체보다 전층 파열로 진행하는 일종의 질환 스펙트럼(disease spectrum)의 개념으로 전층 파열에 비해 현재까지 발표된 연구 자료가 많지 않다. 즉 회전근 개 부종, 견봉과의 마찰로 생긴 염증성 건병증, 회전근 개 섬유화 및 부분 또는 전층 파열로 진행되는 회전근 개 병변의 스펙트럼의 일부로 간주되는 경우가 많다. 본 종설은 회전근 개 부분 파열의 진단, 파열 분류, 수술의 적응증 및 수술 방법과 그 결과에 대해 논하고자 한다.
