We experienced a case of congenital paraesophageal hiatal hernia[Type;IV in seventeen day-old female and treated through the right thoracotomy, reduction of the herniated viscera ,stomach and some part of transverse colon and omentum by gentle finger push, and narrowing the esopahgeal hiatus. Paraesophageal hiatal hernia accounts for only 5% per cent of all diaphragmatic defects but is a potentially dangerous lesion due to compressed lung by the herniated viscera. Symptoms are related to this, including exertional dyspnea, vomiting, cough, Tachypnea but noncyanotic, etc. Barium study shows that the stomach has herniated into the right pleural cavity. The speckled appearance in the herniated stomach in the herniated stomach was due to food material. It strongly suggests paraesophageal hiatal hernia. The operation was done. We report the case with the brief review of literatures.

Phrenic nerve injury has been reported with the use of iced slush for topical cardiac hypothermia. A review of the preoperative and the postoperative chest roentgenograms was performed to detect phrenic nerve injury in patients undergoing cardiac operation with the use of iced slush for topical hypothermia from January, 1985 to June, 1987. The reviewed series included 45 patients who had undergone valve replacement. In this review, the injured site of phrenic nerve was left in 13 cases, right in 1 case and the overall incidence of phrenic nerve paralysis following open heart surgery was 31%. Compared to the incidence of phrenic nerve paralysis in the control group [without pericardial insulation] [406, 12 cases/30 cases], that in the group of patients receiving pericardial insulation [13.3%, 2 cases/15 cases] was lower, but there was no statistical significance. The initial time that diaphragmatic paralysis developed was mean 3.5 days [range 1-8 days] postoperatively and the recovery time of the paralysis was mean 4.7 months [range 0.5-10.5 months] postoperatively.

During a 12-month period, 31 patients underwent diagnostic and therapeutic thoracoscopy for previously undiagnosed thoracic diseases. In all patient, the diagnosis had been unobtainable by the usual diagnostic modalities of thoracentesis, closed pleural biopsy, bronchoscopy, or mediastinoscopy. The patients ranged from 4 years to 84 years old. One procedure was performed for mediastinal mass, 8 for parenchymal lesions, 21 for pleural diseases, and 1 for diaphragmatic disease. A correct diagnosis was obtained by thoracoscopy in 31 procedures for a 90% overall accuracy rate. There was no clinically significant morbidity in this series and no procedure-related mortality. Thoracoscopy, performed under intercostal nerve block and regional anesthesia, has proved to be a very attractive method of the diagnosis of thoracic disease.

We report the case of a 17-year-old girl who presented with an indentation in the right ventricle caused by an incomplete pericardium on preoperative 3-dimensional reconstructed computed tomography. She was to undergo surgery for a partial atrioventricular septal defect and secundum atrial septal defect. Preoperative electrocardiography revealed occasional premature ventricular beats. We found the absence of the left side of the pericardium intraoperatively, and this absence caused strangulation of the diaphragmatic surface of the right ventricle. After correcting the lesion, the patient's rhythm disturbances improved.

Ventricular assist device(VAD) has been clinically applied as a temporary circulatory sup- porting system in the patients with severe heart failure, but small sized VAD for infant is not available. The purpose of tilis paper is to introdIAce small sized VAD and presents the result of in vitro test. Sejong VAD is diaphragmatic type of pneumatic pump and stroke volume is 11cc. Cardiac outputs of the Sejong VAD were measured by overflow tank under variable conditions of driving parameters. The cardiac output was 1.3 1/min at the heart rate of 120 per minute, left atrial pressure of $15cmH_2O$, percent systole of 43%, driving pressure of 240 mmHg, vacuum pressure of -40 mmHg, and mean aortic pressure of 70 mmHg. No mechanical problem was developed during the continuous in vitro test for 3 months.

This study was conducted to observe the condition of the ramification of the bronchus and pulmonary blood vascular system by injection of vinylite into the bronchial tree and pulmonary blood vessels in normal adult swines. The results obtained were summarized as follows. 1. Lungs of swine were composed of the same pulmonary territories as in lungs of human and dog. 2. Bronchial tree of swine also were axial divergency in the patterns. 3. Ramification of the left and right apical lobes are especially complex patterns but cardiac and diaphragmatic lobes are a little monotonous. 4. Intermediate lobe corresponding to mediobasalis branch of human lungs formed only one lobe in swine lung. 5. Pulmonary artery of right apical lobe was mono branch form in all case by authors observation. 6. $B._2$ streched into the seg. dorsalis of the right apical lobe was especially developed compare to $B._1$, $B._3$ of the seg, apicalis and seg, ventralis.

This is a report of a. case in which a long narrow segment coarctation of the aorta was successfully corrected with Teflon graft. The patient was 30 year old man with hypertensive symptoms that occurred 7 years prior to operation. Blood pressure measured 230/110 mmHg in the arms and 110/80 mmHg in the legs. Pulses were strongly tensive in radial artery, but very weak in femoral artery and even absent in dorsal pedis artery. Final preoperative diagnosis was made by aortography which showed a long narrow segment between aortic arch and descending thoracic aorta and highly developed collateral circulations. A long hypoplastic narrow segment was located proximal to the ligament arteriosus, and diaphragmatic stenosis of the aorta was located just distal to the ligamentum arteriosus. After prosthetic correction of the coarctation of the aorta, blood pressure were measured 130/ 80 mmHg in the arms and 150/100 mmHg in the legs. Peripheral pulses were palpated normally, and the postoperative course was uneventful.

Supradiaphragmatic liver is a rare condition. Establishing an accurate preoperative diagnosis is difficult. Operative exploration is necessary to differentiate this lesion from intrathoracic masses, such as a pleural based tumor, diaphragmatic tumor and peripheral lung tumor. However, with the aid of the hepatocyte-specific magnetic resonance imaging contrast agent, gadoxetic acid (Gd-EOB-DTPA), functional hepatocytes in the lesion can be identified in the hepatobiliary phase, potentially allowing an accurate and non-invasive diagnosis. We report a case of supradiaphragmatic liver diagnosed by Gd-EOB-DTPA-enhanced magnetic resonance imaging.

Foramen of Morgagni hernia is the least common type of all congenital diaphragmatic hernias. These foraminal hernias result from a congenital defect in the development or attachment of the diaphragm to the sternum and costal arch. They occur most commonly on the right side, possibly because of pericardial reinforcement of the left. In our case, occurred on the right side and the contents of the hernial sac were omental fat and a part of transverse colon. We performed transthoracic approach for reduction and repair of foraminal hernia with ligation and interrupted mattress sutures of the margin of the defected diaphragm to the posterior part of the sternum and costal cartilage. The postoperative course was uneventful except posttraumatic delirium and discharged at 21st postoperative day.
