A congenital fistulous communication between the coronary artery and the cardiac chamber or the pulmonary artery is a rare condition, but increasing cases with this anomaly are being recognized with wide spread use of cardiac catheterization and coronary arteriography. Recently we experienced one case of right coronary artery fistula which was associated with atrial septal defect. The patient was a 24 year old female who was admitted because of cardiac murmur, palpitation and dyspnea on exertion after pregnancy. Cardiac catheterization and selective coronary arteriography revealed that a fistulous communication, forming a large aneurysm, was noted from the right coronary artery emptied into the right ventricle. On the operation field, the right coronary artery was curved and markedly dilated from the aorta to the middle segment at acute margin of the right ventricle. The egg-sized aneurysm of dilated right coronary artery was noticed on right ventricle. The aneurysm was incised longitudinally and both the proximal opening and the termination site of the fistula were closed directly with aneurysmectomy. The right atrium was also opened to evaluate the fistulous termination site and repaired only small interatrial septal defect. Postoperative course was uneventful and she was discharged without problems

Manual or mechanical compression followed by 4 to 8 hours of bed rest is still the standard technique for accessing site management of the femoral arterial puncture site. But these methods are often uncomfortable and delay hospital discharge. Recently, a number of new devices to achieve hemostasis have been developed. These devices uses collagen to facilitate local hemostasis. But many complications associated with the use these devices have been reported internationally. We present a case of successful treatment of Rt. femoral and Rt. popliteal arteries thrombosis caused by Angioseal.

Orthognathic surgeries often utilize rigid fixation for stabilization of the osteotomy site. The longterm fate of rigid fixations is still under investigation, and whether they should be routinely removed is under debate despite their low complication rates. Here, we report a case where a 26-year-old man suffered high-velocity trauma to his face 7 years after a two-jaw surgery. Computed tomography examination revealed a zygomaticomaxillary complex fracture, and open reduction and internal fixation was performed along with anterior maxillary wall reconstruction using absorbable mesh. Intraoperative examination revealed a broken L-shaped titanium plate near the fracture site with multiple bony fragments near each titanium screw. The rigid titanium system may have caused comminution of the fracture pattern, worsening the severity of the fracture.

Increasing success in the management of patients with severe respiratory failure by mechanical respirators has produced iatrogenic tracheal stenosis. And the surgical management of these lesions have provided a major field for tracheal reconstructive surgery. Recently we have experienced three cases of postintubation tracheal stenosis between December, 1985 and October, 1987 and successfully performed circumferential resection and end to end anastomosis of the trachea. The lesion of the first case which was located in the subcricoid level was resected about 2cm length with cervical incision. And the lesion of the second case located at the cuff site was also resected about 2.5cm length with cervical and median sternotomy incision. Also the lesion of the third case located at the stoma site was resected about 1.8cm length with cervical incision. The postoperative courses were uneventful but there was extubation difficulty in the third case because of stupor mentality and problem of secretion excretion. So we have observed the postoperative course after T-tube insertion.

We reviewed 10 cases of traumatic diaphragmatic injuries at Soonchunhyang University Gumi Hospital from January 1990 through April 1993. Seven patients were male and three patients were female. The age distribution was ranged from 25 to 79 years, predominant 4th decades occurred in male. The traumatic diaphragmatic injuries were due to blunt trauma in 9 cases[traffic accident 7 and crash injury 2] and penetrating wound in 1 case[stab wound]. The common symptoms were dyspnea[60%], chest pain and abdominal pain in order frequency. In the blunt trauma and crash injury, the rupture site was all located in the left[ 9 cases ]. In the penetrating wound, the rupture site was located in the right[1 case]. The surgical repair of 10 cases were performed with transthoracic approach in 9 cases and thoracoabdominal approach in 1 case. The postoperative mortality was 10%[1/10]. The cause of death was multiple organ failure with pulmonary edema.

Dissecting aortic aneurysm is a disease which is characterized by hemorrhagic intramural seperation of aortic wall and extension for varlng distances proximally, distally, or both from the site of the intimal tear. Most aortas show some type of medial degeneration most commonly described as cystic medial necrosis. DeBackey classified this disease according to involved aorta and site of intimal tear to 3 basic types, such as type I, II and III. Type III is defined that dissecting process arrises in the descending thoracic aorta just distal to origin of the left subclavian artery and extends distally for a varing distance. We expirienced a case of dissecting aneurysm, type III of DeBackey's classification which dissecting process is limited to the descending thoracic aorta in the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. This patient was 40 year old woman and she had suffered from intermittent sharp back pain for 3 years .before admission. Excision of the aneurysm and Dacron graft were placed successfully under the left atrio-femoral bypass with artificial pump. The hospital course was uneventful.

Postemetic rupture of the esophagus is an intrathoracic catastrophe which is universally fatal if untreated immediately. We have experienced one case of Boerhaave`s syndrome at the Thoracic & Cardiovascular Surgery Yonsei University College of Medicine. He was 56 years old male who complained severe chest-pain, dyspnea with sudden vomiting after alcohol. Esophagogram showed barium leakage through rupture site on lower esophagus into left thoracic cavity. He had taken repair of the rupture site of lower esophagus and wrapping it with the body of the stomach wall because of relatively clean rupture margin even though 48 hours following the rupture. He has been uneventful in post-operative courses & he discharged with good conditions.

It is well known that the essential pathology in traumatic anterior dislocation of the shoulder is the avulsion of the glenohumeral ligament complex from the glenoid rim, However, there were some reports that the avulsion can occur from the humeral attachment site. We have experienced a 42-year-old man who had complained of persistent shoul­der pain after traffic accident and showed the instability on physical examination. The MR arthrogram and arthro­scopic surgery revealed the avulsion of glenohumeral ligament from the humeral attachment site. We repaired the lesion using the suture anchor through the anterior axillary approach and had a good result after 1 year.

Pyriform sinus perforation is a rare complication of endotracheal intubation. It most commonly occurs at the hands of the less experienced physician in emergency situations. It can occur after traumatic intubation and is potentially lethal. The site most commonly perforated is the pharynx, posterior to the cricopharyngeal muscle; the second most common site is the pyriform sinus. We report a case of pyriform sinus perforation after endotracheal intubation, which was successfully treated with primary closure.

Metal-binding antibiotics are very attractive choices as cation selective ionophores. The ability of tetracycline (TC) antibiotics to bind to metal ions has obtained much attention. TCs exhibit the potentiometric performance changes for various cations dependant on several experiment conditions. In this report, we investigated the potentiometric performance changes of TC as the modification of TC's possible metal binding site. We found that the selectivity alter with the blocking main binding site of ionophores for cations. And, additionally it is possible to control the selectivity of sensors with chemical modification of ionophores.
