Percutaneous transluminal angioplasty(PTA) were performed in three patients with atherosclerotic stenosis of subclavian arteries. The arteries were successfully dilated without complications during the procedure. All patients were asymptomatic during follow-up periods ranging from eight months to fifteen months after PTA.

Emphysematous pyelonephritis is rare but freuently fatal complication of renal parenchymal infection, mostcommonly occurs in diabetic patients and is often associated with urinary obstruction, prior urologicalabnormality or infection. From 1898 to 1984 , about 50 cases of empysematous pyelonephritis have been reporteduniversally. The diaignosis of emphysematous pyelonephritis can be made only roentgenographically. In the last 2years, we have had two cases of emphysematous pyelonephritis at our hospital. It is our purpose to report twopatients who have survived wtih a brief review of the previous literature.

CT has become the most useful, non-invasive diagnostic method as the initial exmination in the diagnosis ofruptured intracranial aneurysm with intracranial hemorrhage(subarachnoid, intracerebral and intraventricularhemorrhage), hydrocephalus and infarction. Furthermore, high resolution CT can demonstrate aneurysm itself. Butangiography is the last and conclusive method as yet, for better evaluation of vascular anatomic structure ofaneurysm for surgery. Authors analyzed 40 cases of ruptured intracranial aneurysm confirmed by CT, angiographyand/or surgery at Chonnam National University Hospital from July, 83' to July, 85'. The results were as follows:1. The most prevalent age group was the 5th decade(35%), and female patient(57.5%) was more comon than male. 2.Angiographic findings were as follows: 1) Multiple aneurysm was found in 8 patients (20%): the one of thesepatients is tripple, the others are double. 2) The location of aneurysm, in order ot frequency, were : ACA andA-com aneurysm in 23 cases(47%). ICA and P-com aneurysm in 17 cases(35%), basilar tip aneurysm in 4 cases(8%), MCAaneurysm in 3 cases(6%) and PCA aneurysm in 1 case(2%). 3) Hydrocephalus was detected in 22 cases (55%): 21 cases(95%) of these cases were demonstarated within the first 3 weeks after attack. 4) Detection of aneurysm itseslfwas 20 cases(50%). 5) Cerebral infarction was 5 cases(12.5%). 6) Subarachnoid enhancement on post-contrast scanwas 8 cases(20%).

PURPOSE: The purpose of this study was to evaluate the utility of the CT cholangiography by using helical CT with multiplanar reformation in patients with extrahepatic biliary obstruction. MATERIALS AND METHODS: Helical CT was performed in 36 patients of extrahepatic biliary obstruction confirmed by operation or invasive cholangiography(percutaneous transhepatic cholangiography or endoscopic retrograde cholagiopancreatography). The cause of obstructions were 18 benign diseases(11 common bile duct stones, four choledochal cysts, three pancreatitis) and 18 malignant diseases(seven common bile duct carcinomas, seven pancreatic head carcinomas, three ampullary carcinomas, one periampullary duodenal carcinoma). After helical scanning through the extrahepatic bile duct, retrospective reconstruction of the helical data was performed. And then, CT cholagiogram was obtained with multiplanar reformation. We evaluated the technical success rate and the accuracy in determinating the level and the cause of the obstruction. We compared findings of the CT cholangiogram with that of operation or invasive cholangiography. RESULTS: In 100%(36/36) of cases, CT cholangiography could be obtained successfully. The accuracy of the CT cholangiography in determinating the level of the obstruction was 100%(11 cases of suprapancreatic duct, 13 cases of intrapancreatic duct, 13 cases of infrapancreatic duct and ampulla), and the accuracy in determinating the cause of the obstruction was 91.7%(all cases of 18 benign diseases, and 15 cases of 18 malignant diseases). CONCLUSION: In evaluating the obstruction of extrahepatic bile ducts, the CT cholangiography by using helical CT with multiplanar reformation is an useful noninvasive method in determinating the level.and the cause of biliary obstruction and therefore could replace t~e invasive cholangiography.

PURPOSE: To evaluate clinical usefulness of magnetic resonance angiography(MRA) as a diagnostic modality and for treatment planning of intracranial arteriovenous malformations(AVM). METHODS AND MATERIALS: In 14 patients with intracranial AVM which were confirmed by operations, radiologic studies and clinical evaluations, magnetic resonance imaging(MRI), MRA and conventional angiography(CA) were retrospectively reviewed with specific regards to nidus depiction, detectability of feeding arteries and draining veins, and number and anatomic consistency of these vessles. MRA was obtained by 3 D TOF, 2 D PC, and 3 D methods with adequate VENC selection. RESULTS: Nidus of AVM was well demonstrated in MRI and MRA, and no remarkable difference in detection and size estimation of nidus among MRI, MRA and CA except 2 cases of associated intracranial hemorrhage, in which 3 D PC MRA well depicted nidus that were not visualized on MRI because of subacute hemorrhage. Feeding arteries were well demonstrated on 3 D TOF and 3 D PC MRA. Dilated draining veins were well depicted on 3 D PC MRA by scannig with adequate VENC selection, and the results were no remarkable difference compared with the ones on CA. CONCLUSION: MRA of a consecutive scan after MRI is a excellent modality for evaluation and treatment planning of intracranial AVM, and possible substitutive method for CA except for radiotherapy or transarterial embolization.

PURPOSE: The purpose of this study is to compare CO2 DSA and nonionic contrast media angiography in respect to the quality of the opacification of collaterals and incidence of side-effects in peripheral occlusive arterial disease. MATERIALS AND METHODS: Sixteen patients who were suspected to have peripheral occlusive arterial disease were performed angiography with nonionic contrast media and CO2 at the same location with the same catheter. The causes of the lesions were atherosclerosis(n=7) and Buerger's disease(n:9). CO2 DSA was compared with nonionic contrast media angiography in respect to the quality of image in the diagnosis of the lesions, opacifications of collaterals and side-effects. RESULTS: In atherosclerosis;quality of the images of CO2 DSA was same as that of nonionic contrast media angiography in 6 patients and was poor in 1 patient;opacifications of collaterals of CO2 DSA were same as that of nonionic contrast media angiography in 5 patients and was poor in 2 patients. In Buerger's disease;quality of the images of CO2 DSA was same as that of nonionic contrast media angiography in 2 patients and was poor in 7 patients;opacifications of collaterals of CO2 DSA were same as that of nonionic contrast media angiography in 1 patient and was poor in 8 patients. Leg pain was the only side-effect after CO2 injection occuring in 4 out of 16 patients. CONCLUSION: CO2 could be used as safe contrast media in patient with risk factors for nonionic contrast media and for diagnosis of the atherosclerosis in lower extremity. For the procedures such as vascular intervention reguiring large amount of contrast media CO2 could effectively replace nonionic contrast media.
