환자는 남자 33세이며 외상으로 인하여 좌측쇄골하동맥에 낭형의 가성동맥류가 발생했고 수술은 동맥류낭을 부분절제하고 Dacron 인조혈관을 이식하였다. 술후경과는 비교적 양호하였으며 관계된 문헌의 고찰과 함께 보고 하였다. A 33 year-old man was admitted with chief complaints of severe sharp pain on left upper interscapular region and motor weakness of left arm for 9 days. He had a history of blunt trauma over left shoulder about 3 years ago. Physical examination showed a ping pong ball sized mass which was located at the left supraclavicular area and was firm, fixed, and nonpulsatile. No bruit or murmur was obtained over the mass. Ipsilaterally, radial, ulnar, and brachial pulse were very weak and ptosis and anhidrosis were noticed. Neurologic examination revealed moderate or severe weakness of flexion and extension of left elbow, wrist and fingers, and anesthesia of the skin in left C8-T1 dermatome and hypalgesia in left C6-C7 dermatome. Retrograde aortography demonstrated complete obstruction of left subclavian artery. An exploratory operation was performed through the left 4th intercostal space. It was found that the mass was a left subclavian aneurysm of traumatic false type. Proximal and distal ligation of the aneurysm were applied and the sac was partially removed. The continuity of the subclavain artery was established by the use of a 6mm. Dacron graft from the root of the subclavian to the axillary artery. Postoperatively the patient was improved from the circulatory and neurologic disturbances.

Six cases of congenital heart disease were operated on by means of cardiopulmonary bypass between December, 1975 and April, 1976. Two cases of ventricular septal defects (VSD), two cases of VSD, associated with ruptured aneurysm of sinus Valsalva, two cases of atrial septal defects (ASD) and one case of pulmonic stenosis with patent ductus arteriosus were operated. Sarns roller pumps and Bentley Temptrol oxygenators were used for extracorporeal circulation. Pump oxygenator was primed with Ringer's lactate solution, 5% dextrose in water, mannitol, and ACD blood. Flow rate ranged from 2.0 to $2.4L/M^2/min$. Bicarbonate was added to the oxygenator with estimated amount as 15 mEq/L/hr. Venous catheters were introduced into superior and inferior vena cava, and oxygenated blood was returned to the body through aortic cannula inserted into ascending aorta. Moderate hypothermia ($30^{\circ}C$) was induced by core cooling. Aorta was cross clamped for 15 minutes and released for 3 minutes, and repeated clamping when necessary. Atrial and ventricular septal efects were closed by direct sutures. Aneurysms of sinus Valsalva ruptured into the right ventricle were repaired through right ventriculotomy by d:rect closure with Dacron patch reinforcement. Cardiopulmonary bypass time varied from 66 to 209 minutes, and aorta cross clamping time ranged from 13 to 56 minutes. Postoperative bleeding was minimal except one case who needed for evacuation of substernal hematoma. Intra- and postoperative urinary output was satisfactory. Acid-base balance, partial pressure of $O_2$, electrolytes, and hematological changes during intra- and post-perfusion period remained at the acceptable ranges. No mortality was experienced.

A model test is carried out to investigate the vibration of truss type lift gate in the four major rivers project. The gate model scaled with the ratio of 1 : 25 is made of acryl panel dimensioned 1.6 m in width, 0.28 m in height in the concrete test flume. Firstly natural frequencies of the model gate are measured and the results are compared with the numerical results in order to verify the model. The amplitudes of the vibration are measured under the different gate opening and water level conditions. The results are analyzed to study the characteristics of the gate vibration according to the small gate opening, the large gate opening and the overflow conditions. These test results presents a basic data for the guide manuals of gate management and a design method to reduce the gate vibration of truss type lift gate. Finally, the vibration of truss type lift gate are assessed in comparison with those of formerly tainter gate.

개심술시 Activated Clotting Time 을 이용한 Heparin 및 Protamine 양 조절에 관한 임상적 관찰
김춘동,이성행,Kim, Chun-Dong,Lee, Sung-Haing 대한흉부심장혈관외과학회 1980 Journal of Chest Surgery (J Chest Surg) Vol.13 No.4
It has been proposed that wide individual variation in response to heparin be not considered in the conventional set protocol for the control of heparin and protamine during extracorporeal circulation. In this paper, two protocol of heparin and protamine therapy were compared to assess the role of the Activated Clotting Time [ACT] in relation to heparin, protamine, and postoperative blood loss and transfusion. The study groups consisted of the 31 patients [adults 15 and children 16] anticoagulated with the conventional heparin protocol and the 31 patients [adults 15 and children 16] anticoagulated with ACT protocol during extracorporeal circulation. In the conventional heparin protocol, two mg of heparin per kg was administered initially with an additional 0.75 mg of heparin per kg every 30 minutes of extracorporeal circulation, and reversal was accomplished with protamine in a dose of 1.5 times the total milligram of heparin. In the ACT protocol, two mg of heparin per kg was administered initially with an additional dose of heparin enough to reach an ACT of 480 seconds [within safe zone 300 to 600 seconds] from the patient`s dose response curve every 1 hour of extracorporeal circulation, and reversal was done with protamine in a dose of 1.3 times the milligram of the residual heparin. The results were summarized as follows. After a dose of 2 mg per kg of heparin, the patient`s ACT varied from 240 to 600 seconds in adults and from 240 t~ 660 seconds in children. In the ACT group the total amount of heparin administered was markedly reduced when compared to the conventional group, and less protamine was required to neutralize heparin. The dose of heparin administered decreased from 7.07 [SE 0.42] mg/kg of the conventional group to 4.92 [SE 0.32] mg/k8 of the ACT group in adults and from 10.17 [SE 1.15] mg/kg to 5.23 [SE 0.24] mg/kg in children, which represent 30.4% and 48.6% decrease respectively. The dose of protamine administered for reversal decreased from 10.6 [SE 0.63] mg/kg of the conventional group to 3.35 [SE 0.35] mg/kg of the ACT group in adults and from 15.7 [SE 1.70] mg/kg to 3.26 [SE 0.27] mg/kg in children, which represent 68.4% and 79.2% respectively. The ratio of protamine to heparin administered in the conventional group was 1.50:1 in adults and 1.54:1 in children, but in the ACT group 0.68:1 in adults and 0.62:1 in children. Postoperative blood loss and transfusion revealed no statistically significant difference between the two groups. Although six patients in the conventional group and one in the ACT group needed re-exploration for continuous hemorrhage, no case of generalized oozing was encountered, and in each case a definite bleeding site was identified. Author would like emphasizing the value of the ACT protocol in controlling heparin and protamine administration during extracorporeal circulation.

Studies of cardiopulmonary function and acid-base balance were performed on 29 dogs during control period, during oligemic hypotension and following return of blood to the animals. Intravenous morphine and local anesthesia were used. Fifteen of the 29 animals survived the complete experiment. The 14 animals that failed to survive the experimental period died between 15 to 90 minutes after the onset of bleeding. The results were as follows. 1. The heart rate increased after the onset of bleeding and failed to return to control level following reinfusion. Stroke volume decreased markedly after bleeding and failed to recover after return of blood from the reservoir. Cardiac output also decreased during oligemic hypotension and was maintained at this level after re-infusion. Total peripheral resistance decreased significantly immediately after bleeding, however it increased soon over the pre-bleeding level. Central venous pressure decreased after the onset of bleeding and remained at lower level for the rest of the experimental period. Arterial blood pressure, clown to 40-45 mmHg by acute hemorrhage, was elevated near to control level. Left ventricular work decreased tremendously during oligemic hypotension and failed to return to control level with the re-infusion of blood. Hematocrit value showed no significant decrease after bleeding and increased after re-infusion. Hemoglobin decreased after the onset of bleeding and recovered to control value after re-infusion. 2. The respiratory rate fell rapidly after bleeding from 124 to 29 and remained at this lower level for the remainder of the experiment. The tidal volume increased after bleeding and was maintained at this level for the remainder of the experiment. The respiratory minute volume showed no significant changes throughout the experimental period. Oxygen consumption fell lightly in all animals during oligemic hypotension and returned to normal levels following re-infusion. Arterial oxygen content and arterial oxygen saturation decreased following bleeding and the values returned to normal levels after the return of blood from the reservoir The arterio-venous oxygen difference increased after the onset of bleeding. It failed to return to normal values following re-infusion. Arterial $Pco_2$ decreased in all animals after the beginning of the bleeding. Partial pressure of $Co_2$ continued to fall until re-infusion, after which the values returned toward normal. Animals became acidotic. The pH fell to lower level following bleeding. Lactic acid and lactate: pyruvate ratio also increased during same period. Arterial pH and lactic acid failed to return to control value and lactate: pyruvate ratio increased more after re-infusion. Sodium bicarbonate decreased after bleeding and returned to control value following re-infusion.

Rupture of a bronchus is an unusual result of nonpenetrating trauma to the chest. This case was a 19 year old male who was a worker in the mine. The patient had sustained a compression chest injury without external wound or rib fracture. At five days after trauma, he was suffered from dyspnea and the symptom was progressively increased. Two weeks after the chest trauma, a diagnosis of left main bronchial obstruction due to traumatic bronchial rupture was made by means of bronchoscopy and bronchography. He was operated upon. The left lung was completely atelectatic and the left main bronchus was found to be transected at the level of 3cm from carina. End-to-end anastomosis of the bronchus was performed and the left lung was aerated very well. postoperative course was uneventful.

The bronchogenic cysts result from an abnormal budding or branching of the tracheo-bronchial tree from the primitive foregut. Bronchogenic cysts may be pulmonary or mediastinal. The most common location for a mediastinal bronchogenic cyst is in relation to the carina. They are usually solitary. They usually are thin walled and contain fluid that is most often clear. The cyst is lined by ciliated columnar epithelium. The bronchogenic cyst i~ usually asymptomatic. They can cause pressure symptoms. When they become infected, symptoms do occur. We report 3 cases of bronchogenic cysts experienced at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. Case I, a man of 20 year-old, had a cyst at the site between aortic arch and left pulmonary artery. He complained cough and dyspnea. The cyst wasn`t communicated with tracheobronchial tree. Case II was 55-year-old male who had had hemoptysis. A huge cyst was located within the lower lobe of left lung and removed by pulmonary lobectomy. There were not any symptoms in Case III that was 6-year old girl. That cyst was located just next to the right main bronchus.
