Heart size in new-born infants

Cardiac size of 291 new-born infants was measured using the method illustated on Fig 1. Among the 291 infants,53 were asphyxiated, and asphxia was only regared from Apgar score below 6 on 1 min. and 5 min. Remaining 238infants were normal, and classified to group with lung abnormalities and without lung abnormalities on chest A-Pfilm. The results are as follows; 1. The average CTR. of normal group was 52.37(C/T1;54.89, C/T2;49.43, C/T3;49.15, C/T;55.97) 2. The average CTR. of asphxiated group was 54.91 (C/T1;57.13, C/T2;51.69, C/T3;51.94,C/T4;58.25) 3. Consequently, asphyxiated infants revealed larger cardiac size than normal infant group.

A radiologic analysis and comparative evaluation of hysterosalpingographic and laparoscopic findings ininfertile patients

Hysterosalpingograms of 375 patients with infertility were reviewed with reference to radiological features of each pathology and a comparative study of hysterosalpingography and laparoscopy in 36 patients was presented. The results were as follows; 1. In 375 cases infertility, 191 cases (50.9%) were primary infertility and 181 cases(49.1%) were secondary infertility. 2. The peak age distribution was 26 to 30 year old group in 211 cases (56.3%),and the peak duration of infertility was less than 3 years in 256 cases (68.3%). 3. Abnormal uterine findings were 115 cases (30.7%) and there were 73 cases of filling defects, 13 cases of irregularity , 12 cases of uterineflexion, 11 cases of congenital anomaly, and 9 cases of hypoplasia among them. 4. Abnormal tubal findings were 196 cases (52.3%) and there were 103 cases of simple obstruction, 69 cases of hydrosalpinx, and 50 cases of peritubal adhesion among them. 5. Intravasation of contrast media was noted in 42 cases (11.2%). 6. In 36 cases of laparoscopy, 23 cases (63.7%) was agreed to hysterosalpingography. 7. Aothough laparoscopy was better than hysterosalpinography in external anatomy of salpinx and relationship to overay, hysterosalpingography should be important for fundamental study of infertile women because of lower failure rate, lower risk of complications,therapeutic effect, and lower cost.

Double chambered right ventricle

Fourteen cases of double chambered right ventricle were diagnosed angiographically and of these nine caseswere confirmed after operation and autopsy at Seoul National University Hospital in recent four years since 1979.The clinical and radiological findings with the emphasis on the cinecardiographic findings were analysed. Thesummaries of the analysis are as follows; 1. Among 14 cases, 6 cases were male and 8 cases were female. Agedistribution was from 4 years to 36 years. 2. In chest X-ray findings, pulmonary vascularity was increased in 8cases, decreased in 4 cases, and nomral in 2 cases. Cardiomegaly was observed in 8 cases and other showed normalheart size. 3. In cinecardiography, 11 cases had interventricular septal defect. Among these 11 cases, VSD locatedin proximal high pressusre chamber was in 2 cases and located in distal low presssure chamber was in 9 cases. 4.The location of aberrant muscle bundle in sinus portion of right ventricule was in 8 cases. In the rest cases, andaberrant muscle bundle was located below the infundibulum of right ventricle. 5. For accurate diagnosis anddifferential diagnosis with other congenital cardiac anomalies such as Tetralogy of Fallot or isolated pulmonicstenosis, biplane cineangiography and catheterization is an essential procedure.

Chest PA findings of leukemia in children

Leukemia is the commonest malignancy in childhood, accounting for about one-third of all malignancies in thosebelow the age of 15 years. Authors analysed the chest PA findings of 177 cases of leukemia in childhood below theage of 15 years, diagnosed at Seoul National University Hospital in recent 5 years since 1978. The summaries ofthe analysis are as follows; 1. Among 177 cases, 121 cases were male and 56 cases were female. The malepredominant than the female with the ratio of 2.2:1. In 177 cases, 77% of the patients were under the 10 years ofage. 2. The incidence of subtype of leukemia was as follows; The acute form was 158 cases (89%), acute lymphocyticleukemia, 55%, acut myelocytic group, 31.6%, chronic myelocytic type, 10%. And acute lymphocytic leukemia was61.4% of acute form. 3. The incidence of abnormality in chest PA was 32.2%(57 cases) . Among these 57 cases,abnormality in lung field was 35 cases (19.8% of total patients) hilar and mediastinal lymph nodes enlargement was19 cases(10.7%). Pleural effusion was 13 cases (7.3%) and cardiac shadow enlargement in chest PA was 3 cases.

Congenital coronary arteriovenous fistulae

Six cases of congenital coronary arteriovenous fistulae were diagnosed radiographically and confirmed afteroperation at Seoul National University Hospital in recent three and a quarter years since 1979. The clinical andradiological findings with the emphasis on the cinecardiographic findings were analysed. The summaries of theanalysis are as follows; 1. Among 6 cases, 2 cases were male and 4 cases were female. Age dsitribution was from 3months to 19 years. 2. In chest x-ray findings, 5 cases had cardiomegaly. Among these 5 cases, increase ofpulmonary vascularity was in 3 cases. Chest X-ray finding of the rest 1 case was within normal limit. 3. Thecoronary arteriovenous fistula orginated from the right coronary artery in 5 cases and from the single left coronary artery in 1 case. In 5 cases, a coronary arteriovenous fistula drained into the right ventricle and in 1case, a fistula from a SA node branch of the right coronary artery into the right atrium. 4. In 5 cases, a mainright coronary artery was dilated. Among these 5 cases, aneurysmal dilatation of main right coronary artery was in2 cases, saccular aneurysmal dilatation of distal portion of right coronary artery was in 2 cases and in 1 case,diffuse dilatation without aneurysm formation of a main right coronary artery. In 1 case, SA node branch of theright coronary artery was dilated with aneurysm formation. 5. For accurate diagnosis of congenital coronaryarteriovenous fistula, biplane cinecardiography is an essential procedure.

Two cases of Cantrell's syndrome

Congenital absence of the lower sternum, defect of the abdominal wall, defects of the anterior diaphragm, pericardial defects and cardiac anomalies had been described as a syndrome by Cantrell et al. Developing mechanism of the syndrome was embryologically defined. These defects arise apparently from combined anomalies of developing of the dorsal mesoderm. The authors present two cases of Cantrell's syndrome developed in one day old and eight months old female patient in which angiocardiography was done at the Department of Radiology, Seoul National University Hospital.
