Liposarcoma is extremely rare malignant tumor which develops primary in the orbit. Here, we report a case of primary orbital liposarcoma in 17 year old female patient. She visited our hospital due to decreased visual acuity and protrusion of Rt. eyeball. Malignant tumor was suspected by many examination. So exenteration was performed and tumor mass was confirmed as liposarcoma by pathologic examination. She was received cobalt 60 radiation therapy, but recurrent tumor mass appeared at the orbital apex 1 year after operation.

BACKGROUND: Chaotic atrial rhythm (CAR) is characterized by the presence of three or more P-wave morphologic features on the surface electrogram, absence of a dominant atrial pacemaker, and variable P-P, R-R, and P-R intervals with an atrial rate of over 100 beats/min. CAR is infrequently seen in pediatric ages and its clinical course, management and underlying mechanism are uncertain. We report our recent experience with 11 infants with CAR and describe their clinical characteristics and reponse to treatment. METHODS: We retrospectively reveiwed the medical records, electrocardiograms, Holter recordings, echocrdiographic reports of 11 cases of CAR managed at Sejong general hospital and Asan medical center from January 1991 to June 1995. RESULTS: 1) All patients were < or =6 months old and 5 of 11 patients had symptoms at neonatal period. The duration of follow-up was 3-42 months(mean : 18 months). 2 patients had structural heart disease and 3 patients showed signs of ventricular dysfunction. In 10 of 11 patients tachycardia was sustained or recurrent. 1 patient died of severe congestive heart failure due to incessant rapid tachycardia. 2) 3 of 10 patients took digoxin only and others took more than 2 medications. Full control within 1 month after medication was in 2 patients, with digoxin only in one and digoxin and amiodarone in another patient. At discharge, state of arrhythmia control in 8 patients with medications were full control in 2, good control in 3, and partial control in 3. At last follow-up, full control in 5, good control in 1 were confirmed through Holter recordings and the other 4 patients showed sinus rhythm in surface electrocardiograms. The total duration of medications were < or =1 year except 1 patient. 3) In 3 patients with ventricular dysfunction, ventricular function was normalized after restoration of sinus rhythm. CONCLUSION: CAR in children usually occurs in the first month of life and genenally takes benign course, but sometimes it causes severe congestive heart failure or ventricular dysfunction. Frequently, the patients remain asymptomatic despite persistence of the tachycardia for weeks or months. CAR is difficult to convert to sinus rhythm with medications but tends to resolve spontaneously within 1 year. We think treatment is necessary only in the symptomatic patients with rapid ventricular response and it is enough to control the ventricular rate with antiarrhythmic agents.

BACKGROUND: Diagnosis of aortic arch obstruction can be made with two-dimensional and Doppler echocardiography in most cases.However,not infrequently,clear imaging of the aortic arch can not be obtained,particularly in sick neonates and young infants from a number of reasons and heart catheterization and angiography carries significant risk in sick babies.Therefore it is the purpose of this study to assess the feasibility and safety of counter-current aortography through a peripheral artery in young infants and neotates with suspected aortic arch obstruction. METHOD: We studied 56 patients with suspected aortic arch anomaly at Asian Medical Center from Feburary 1990 to April 1997.First choice for the peripheral artery was radial artery on the same side as the aortic arch,followed by brachial artery and axillary artery.Small 24 gauge plastic cannula was inserted and special attention was given to ensure that the peripheral artery,plastic cannula,and a syringe containing contrast material are all in the same plane.1ml/kg of contrast material was injected by rapid hand injection and biplane cineangiograms were taken at 60 frame/second. RESULTS: Fifty six patients underwent 58 angiograms.Age ranged from 5-255 days(median 30 days) and body weight nanged from 2.1-5.4kg(mean3.4kg).There were 27 males and 29 females.Arteries used were:Radial artery in 37,brachal artery in 19,and axillary artery in 2 cases.Peripheral arteries were ipsilateral side as the aortic arch in 54,contralateral side in 2 and bilateral in 2 cases.In 8 patients heart catheterization was done because of inadequate visualization of aortic arch anatomy and/or need for evaluating other defects.In 48 patients who had periperal angiography only,fluoroscopic time ranged from 0.6 to 3.5 minutes and total procedure time ranged from 10 to 15 minutes.Among these 48 patients,only 11 patients(23%) were given intraveous sedation and 37 patients(77%) did not recieve any sedation.Diagnosis of aortic arch anomaly was aortic coarctation in 38,aortic interruption in 10 and nomal aortic arch in 8 patients.Aortic arch anatomy was well demonstrated in all cases where injected artery was on the same side as the aortic arch.In patients who had angiograms through peripheral arteries contralateral to the side of the aortic arch did not haveadequate visualization of the arch.Compression of the carotid artery did not enhance the imaging of the arch.Simultanous bilateral angiography did not improve the imaging quality as compared to ipsilateral artery angiography.Transient complication,related to cannulation,e.g.,prolonged bleeding was seen in only one patient with aortic interruption.Circulation on the upper extremities was normal after angiography in all patients. CONCLUSION: Counter-current aortography using 24 gauge plastic cannular through peripheral artery is feasible,rapid,safe,economic and relatevely non-invasive procedure and provides adquate imaging of aortic arch obstruction in infants and neonates without risk of heart catheterization and angiography.We,therefore,recommend this procedure in selected patients in whom echocardiographic imaging alone is not conclusive for planning corrective sursery.

We reviewed the clinical and hemodynamic studies in 10 patients with the isolated congenital mitral insufficiency. The patients ranged in age from 6 months to 16 years at the time of diagnosis and the incidence was 0.26% among the total congenital heart disease proven by cardiac catheterization and angiography. In two cases anterior mitral cleft was demonstrated by 2-D echocardiography and/or operation. In two cases left coronary artery was originated from pulmonary artery. Eight cases out of ten presented symptoms indicating varying degrees of left ventricular failure. Apical systolic murmur was heard in all except one, who had only triple rhythm. The electrocardiograms revealed left ventricular hypertrophy in 8 cases and biventricular hypertrophy in 2 cases. Roentgenographically left atrial enlargement was observed in 4 cases. Left arterial and ventricular dimension were increased in 7 cases by echocardiography. In 5 cases of them, pulmonary artery wedge pressure or left atrial pressure was increased. One patient died in congestive heart failure at the age of 10 months and one patient died postoperatively. Other 4 patients have been managed with medication without difficulty.
