PURPOSE: With the technical advancement in arterial embolization and subsegmental resection of liver neoplasm, emphasis has been on more detailed knowledge of normal arterial anatomy and its variation. We analysed the patterns of intrahepatic branches of right hepatic artery. MATERIALS AND METHODS: We retrospectively analyzed intrahepatic branching patterns of right hepatic artery in 165 cases. All cases had a single right hepatic artery which could be traced up to tertiary branches, and also performed rapid drip infusion CT scan, hepatic arteriography with antero-posterior and oblique views, superior mesenteric arteriorgraphy and indirect portography. RESULTS: lntrahepatic branching patterns of the right hepatic artery had eight types of variation. The most common intrahepatic branching pattern was type I: 107(64.5%) which represented 5, 8th branch emerging from the anterior segmental artery and 6, 7th branch from the posterior segmental artery. Type VII :26(15.8%) was the next common type which represented 6th branch emerging first from the posterior segmental artery and 7th branch emerging secondly from the posterior segmental artery. Type VII, VI, III were branched from the posterior segmental artery. Type IV, II, V were branched from the anterior segmental artery. CONCLUSION: These result could be helpful to the planning of treatment, such as hepatic subsegmentectomy or transarterial embolization of the hepatic neoplasm.

Intussusception is the most common cause of acquired intestinal obstruction during infancy and early childhood and requires early diagnosis and treatment. We observed 431 cases of intussusception who admitted at Chungang Gil Hospital from January 1987 to June 1991, and compared the result of treatment with Barium Enema in 302 cases with that of Air Enema in 129 cases. The results were as follows; 1) In sex distribution, males were more affected than females as a ratio of 2:1. 2) In age incidence, 78.2% of the cases were between 3~10 months. 3) Slight seasonal prevalence was noted in spring and autumn. 4) The common symptoms and signs were cyclic irritability (89.1%), vomiting (78.9%), bloody stool (84.9%) and abdominal mass(43.1%). 5) The common diseases accompanied were URI (39.7%), AGE (13.0%) and UTI(1.2%). 6) 5.8% of cases were visited after the 48 hours of symptom onset, in these cases the operation rate was 39.1%. So the longer duration of symptoms persists, the lower reduction rate follows. 7) The most common type of intussusception was ileocolic type, and the lowest reduction rate was noted in ileoileocolic type. 8) In the reduction rate, 87.4% with Barium Enema and 89.1% with Air Enema. 9) After 24 hours of symptom onset, the reduction rate, 74.4% with Barium Enema and 78.6% with Air Enema. 10) Recurrence rate was 9.3% with Barium Enema and 7.8% with Air Enema. 11) In Barium Enema, 1 case of bowel perforation was observed, and he expired with barium peritonitis, in Air Enema, 2 cases of bowel perforation were observed, and cured after operation. 12) We observed some advantages in Air Enema such as simplicity, high reduction rate and absence of fatal complications. And we think that Air Enema is a useful diagnstic and treatment method of intussusception.

Coccidioidomycosis is a rare systemic fungal infection in Korea. However, the incidence of coccidioidomycosis has recently begun to increase due to the increasing incidence of people traveling overseas to endemic areas. In previously reported cases of coccidioidomycosis in Korea, the radiographic findings usually showed a solitary pulmonary nodule, pleural effusion, cavitation, and hilar lymphadenopathy, but no miliary nodules. We report a case of disseminated coccidioidomycosis with miliary nodules in an immunocompetent patient. A 32 year old male, who had traveled in Corona, New Mexico, USA, was admitted for an evaluation of persistent cough with fever. Chest radiography revealed initially diffuse multiple small nodules that appeared to be miliary tuberculosis. However, a subsequent evaluation revealed that he had disseminated coccidioidomycosis.

BACKGROUND: Dobutamine stress echocardiography(DSE) is useful detection of coronary artery disease as a noninvasive test. The purpose of this study is to find predicting factors of multivessel disease (MVD) in DSE. METHODS: Sixty-five patients suspicious of coronary artery disease excluding myocardial infarction on clinical base had undergone DSE and coronary arteriography. We divided the patient group into normal group (22 patients), single vessel disease(SVD) group(25 patients) and multivessel disease (MVD) group (18 patients) according to the findings of the findings of coronary angiogram. DSE findings and hemodynamic change during stress were analyzed and compared in these groups. We defined MVD on DSE as findings of new or aggravating regional wall motion abnormalities in 2 or more coronary artery territories, and significant stenosis on coronary angiogram as stenosis of 50% or more. RESULTS: 1) The numbers of diseased vessel evaluated by DSE showed significant correlation with those evaluated by coronary angiogram. 2) Resting, low-dose and peak-dose wall motion scores were significantly different among 3 groups, being higher in MVD group than in SVD and normal group. 3) Total administered dose of dobutamine in MVD group was significantly lower than that of normal group. 4) Heart rate at peak-dose showed significant difference among 3 groups, but product of heart rate and systolic blood pressure at peak-dose was not significantly different. 5) Frequency of ST segment change was significantly higher in multicessel disease group CONCLUSION: DSE reflects severity of coronary artery disease. and frequency of resting regional wall motion abnormally. wall motion score in low-dose and paak stress seems to be useful as a predictor of multivessel disease. Value of total administered dose of dobutamine, hemodynamic changes and ST segment changes as a MVD remains to be proved.
