PURPOSE: To diagnose the coronary artery disease, it is necessary to have a thorough knowledge on coronary anatomy and normal variations. We performed a morphological study on normal variations of coronary artery in Korean adults. MATERIALS AND METHODS: 1012 cases of coronary angiography were analyzed with particular emphasis on the normal variation of three coronary arteries and their major branches, including origin of conus artery, sinus node artery and atrioventricular node artery and the variation in posterior descending artery and ramus medianus. RESULTS: We found right dominance in 895 cases(88.4%), left domainance in 44 cases(4.3%), and balanced dominance in 73 cases(7.2%). Conus artery branched from right coronary artery in 468 cases(47.6%) and originated in right coronary sinus close to the os of right coronary artery in 515 cases(52.4%). Sinus node artery originated from left circumflex artery in 551 cases(54.4%), from right coronary artery in 442 cases(43.7%), and from both coronary arteries in 19 cases(1.9%). Atrioventricular node artery originated from right coronary artery in 943 cases(93.4%), from left circumflex artery in 59 cases(5.8%), and two atriovenricular node arteries from both arteries in 8 cases(0.8%). Posterior descending artery had the normal pattern in 505 cases(58.6%) and some variation in 357 cases(41.4%). We found short left main coronary artery, less than 2--3 mm, making it hard to cannulate in 172 cases(17.0%). Ramus medianus was found in 165 cases(16.5%) with marginal distribution in 84 cases(8.4%), diagonal distribution in 80 cases(8.0%) and coursing interventricular sulcus as double left anterior descending artery in 1 case(0.1%). Left main coronary artery gave off 4 branches in 8 cases(0.8%). Myocardial bridging was found in only 3 cases(0.3%). CONCLUSION: This study could provide basic morphological data on anatomy and normal variations of coronary arteries in Korean adults.

The corrected transposition of the great arteries is an usual congenital cardiac malformation, which consisitsof transposition of great arteries and ventricular inversion, and which is caused by abnormal developement ofconotruncus and ventricular looping. High frequency of associated cardiac malformations makes it difficult to getaccurate morphologic diagnosis. A total of 18 cases of corrected transposition of the great arteries is presented,in which cardiac catheterization and angiocardiography were done at the Department of Radiology, Seoul NationalUniversity Hospital between Sep. 1976 and June 1981. The clinical, radiogrpahic ,and operative findings with theemphasis on the angiocardiographic findings were analized. The resuls are as follows; 1. Among 18 cases, 13 caseshave normal cardiac position, 2 cases have dextrocardia with situs solitus, 2 cases have dextrocardia with situsinversus and 1 case has levocardia with situs inversus. 2. Segmental sets are {S.L.L.} in 15 cases, and {I.D.D} in3 cases and there is no exception to loop rule. 3. Side by side interrelationships of both ventricles and bothsemilunar valves are noticed in 10 and 12 cases respectively. 4. Subaortic type conus is noted in all 18 cases. 5.Associated cardiac malformations are VSD in 14 cases, PS in 11, PDA in 3, PFO in 3, ASD in 2, right aortic arch in2, tricuspid insufficiency, mitral prolapse, persistent left SVC and persistent right SVC in 1 case respectively.6. For accurate diagnosis of corrected TGA, selective biventriculography using biplane cineradiography is anessential procedure.

Hemophilia, a genetically determined disorder, can be divided into hemophilia A and hemophilia B. Hemophilia A, defined as a sex-linked recessive trait hemorrhagic disease of males characterized by a deficiency of factor VIII occurs about seven times more frequently than hemophilia B which is characterized by a deficiency of factor IX. The complications resulting from hemophilia occurs in virtually every system. This paper is concerned with a rare complication of hemophilia, iliacus hematoma with femoral neuropathy. On case of spontaneous hemorrhage of iliacus muscle with femoral neuropathy in hemophilia was decompressed through a small incision with sump drainage under cover of AHF(Anti-hemophilic factor) concentrated plasma cryoperecipitate followed AHF replacement therapy.

The soleal line in 115 (left; 61, right; 54) cases of tibiae was studied morphometrically by the method of Mysorekar and Nandedkar. 1. The soleal line showed a uniform character throughout in 26 cases and a mixed characters in 89 cases. The bones showing uniform character were seen generally as a lineal line or wide line. 2. The soleal line having mixed characters divided into three parts. In the upper and middle thirds, the major type of line was wide line. In the lower third, the line was commonly seen as a lineal line. In about 12% of the bones examined the line was seen as a groove, particularly in the middle and lower thirds. 3. The soleal line commenced 1-2cm below the fibular facet In about 61% of cases. 4. The length of the soleal line was 10.5cm, and the ratio to that of the tibia was about 30%. The results of this study provide the characters of the soleal tne of the tibia in Korean. The soleal line, unlike the textbook description, generally shows mixed characters of a line.

Angiographic findings were analysed in 11 cases of Behcet'sdisease which was diagnosed clinically in Seoul national University Hospital from July 1982 to June 1983. Arterial involvement was noted in 5 cases and venous involvement in 6 cases respectively. Arterial aneurysm and occlusion were arteriographic findings. Arterial aneurysm was noted at large arteries in all 5 cases and multifocal involvement was noted in 4 cases. Characteristic finding of arterial involvement was protruding saccular aneurysm. Venous involvement was thrombotic occlusion of deep veins in iliac, femoral and tibial areas in all 6 cases. Behcet's disease should be differentiated whenever these arterial or venous angiographic findings are revealed in a young adult.

Twin reversed arterial perfusion (TRAP) sequence is a rare specific anomaly of twin gestation with fused placenta and umbilical anastomosis. This syndrome occurs once in about 34,600 births and reported first by Beneditti in 1533. We report on prenatal diagnosis of a case of TRAP sequence with color Doppler sonography, this case is presented with a brief review of the literature.

PURPOSE: To evaluate the prevalence of the opacification of paranasal sinuses and to correlate the prevalence and severity of the sinus opacification with presence of upper respiratory infection (URI) in infants and children using CT. MATERIALS & METHODS: We analyzed CT scans of 162 children aged under 16 who have no signs and symptoms of paranasal sinusitis. Both sides of maxillary and ethmoidal sinuses were evaluated. We scored from 0 to 3 according to the degree of soft tissue opacification of each sinus and then summed up the scores of each sinus. We divided the children into 5 groups according to their age. We paid particular attention to the following respects: 1) the prevalence of the opacification of the paranasal sinuses in each group; 2) the difference in the prevalence between the children with and without URI ;3) the correlation between the severity of the sinus opacification and the presence of URI. RESULTS: Of 162 children, one or more paranasal sinus opacification was noted in 76(47 %):31(65%) less than 1 year old;11(52%) between 1 and 2 years old;16(53%) between 2 and 6 years old ;15(28%) between 6 and 12 years old;and 3(33%) above 12 years old. In children less than 1 year old, no significant difference in the prevalence of the sinus opacification was found between URI-positive(71%) and URI-negative(58%) subgroups. In chilren between 1 and 12 years old, although the prevalence of the sinus opacification in URI-positive subgroups was much greater than that in URI-negative subgroup, statistically significant difference was noted only in children between 2 and 6 years old. As to the correlation between the severity of the sinus opacification and the presence of URI, these was a statistically significant difference in children between 2 and 6 years old and between 6 and 12 years old. CONCLUSION: Although the exact pathophysiology is not fully understood, the opacification of the paranasal sinuses is not an uncommon finding at CT in children without the signs and symptoms of sinusitis. We think that the clinical correlation is essential in determining the diagnosis and treatment plan in cases that the sinus radiographs or CT scans show the abnormal findings.

Pure ovarian choriocarcinoma of germ cell origin is exceedingly rare neoplasm, and even the presence of choriocarcinomatous elements admixed with other neoplastic germ cell elements is rare. In the most cases, the tumor is admixed with other neoplastic germ cell elemeats, and their presence is diagnostic of noagsatational choriocarcinoma, except for the remote of the tumor being a geatational choriocarcinoma metasttic to an ovarian germ cell tumor. We have experienced a case of nongestational ovarian choriocarcinoma in 10 year dld woman. So we report this case with a brief review of its literatures.

This study aimed to evaluate the appropriateness of cataract surgery and identify the characteristics of patients and surgeons, clinical and functional outcomes, and surgical methods associated with appropriate cataract surgery. For this purpose, Korean cases of cataract surgery were rated as either 'necessity', 'appropriate', 'uncertain' or 'inappropriate', based on RAND/UCLA Ratings. For this assessment, the cases of 222 patients who underwent cataract surgery, on either one or both eyes, were studied. The surgeries were performed by 20 ophthalmologists practicing at one of fourteen medical institutions (university hospitals and general hospitals). Patients were interviewed and clinical data collected. The Doctors were questioned with self-entered questionnaire forms. The medical records were also examined to gain an understanding of the surgical process. The ratings were as follows: 30.6% (68 patients) of surgeries belonged to the bracket "necessity", 46.4% (103 patients) to "appropriate", 15.3% (34 patients) to "uncertain" and 7.7% (17 patients) to "inappropriate". In this study, "necessity" and "appropriate" were defined as "appropriate" (77.0%, 171 patients), and "uncertain" and "inappropriate" as "inappropriate" (23.0%, 51 patients). The low preoperative Snellen visual acuity and visual function, advanced age and male patients were associated with appropriate surgery. It is concluded that appropriate surgery was related to the clinical and functional outcomes (visual acuity and visual function) and patient characteristics (age and male).
