BACKGROUND AND OBJECTIVES: There is little clinical data on the results of using Sirolimus-Eluting Stent (SES) for treating In-Stent Restenosis (ISR). We performed this study to evaluate the clinical outcomes for implanting SES for treating ISR in a real world hospital environment. SUBJECTS AND METHODS: A total of 30 patients with 32 ISRs (males: 73.3%, mean age: 60.2) (focal lesions: 21.9%, diffuse intra-stent lesions: 34.4%, proliferative lesions: 21.9%, total occlusions: 21.9%) were treated with SES after balloon predilation was performed. We evaluated the clinical results and the performed coronary angiography after 6 months. RESULTS: All the procedures were successful. The mean SES diameter and length were 3.0+/-0.3 mm and 27.1+/-5.5 mm, respectively, and the mean acute gain was 2.42+/-0.38 mm. No in-hospital major adverse cardiac events (MACE) were observed. Twenty five patients with 27 lesions (84.4%) underwent coronary angiography at their 6 month follow-up. The late loss and loss index were 0.41+/-0.56 mm and 0.18+/-0.22, respectively. The binary restenosis rate was 7.4% (2/27 lesions). The rate of target lesion revascularization was 3.7% (1/27 lesion). The incidence of MACE at 6 months was 3.3% (1/30 patient). CONCLUSION: Treating ISR with SES is a safe and effective procedure for reducing ISR without the occurrence of acute or sub-acute thrombosis.

The penetrating atherosclerotic ulcer of the aorta resulting from the atherosclerosis of the aortic wall can clinically mimic type III aortic dissection, since both diseases produce the ulceration and dissection of aortic wall. However, their imaging features and pathophsiologies are distinctly different from each other. Familial hypercholesterolemia(FH) menifests overt hyperlipidemia that can results in premature atherosclerosis of the aorta as well as the coronary artery. We report a clinically and radiologically evident case of perntrating atherosclerotic ulcer of the descending thoracic aorta which was developed in a 36-year-oldd heterozygote FH male.

To evaluate the normal range of articular disk postion, MRIs of 25 temporomandibular joints(TMJs) in 19 asymptomatic volunteers were analysed. On the closed mouth sagittal T1 weighted MRI the junction of the posterior band and bilaminar zone was within 10°anterior from the vertical line through the apex of condylar head in 19 (76%) lad within 20°in 23 (92%) TMJs. The intermediate zone of the articular disk was located between the posterior surface of articular eminence and the anterior surface of condylar head in 22 (88%) TMJs. We suggest that on the closed mouth sagittal MRI the junction of the posterior band and the bilaminar zone could be within 10°anterior from the vertical line through the apex of condylar head in asymptomatic Korean persons. If the junction is located more than 20°anterior from the vertical line or the intermediate zone is anterior to the anterior surface of condylar head it is suggested that the disk is anteriorly displaced. Further studies are needed to evaluate the clinical significance of mild anterior displacement of the articular disk(11°-20°) in asymptomatic persons.

Three-dimensional solid model has not been widely used in surgical prediction of orthognathic surgery because freque from occlusal restorations or prosthesis limited the usefulness of simulated surgery involving occlusion. We prepared three-dimensional(3D) solid model from CT data and integrated the 3D solid model with dental cast using a face-bow transfer technique combined with skeletal reference measurement and confirmation with cephalometric radiographs. With this simple and easy method, it was possible to predict bony interference between the proximal and distal segment of the mandible so that we can prevent condylar displacement after sagittal split ramus osteotomy of the mandible with prominent asymmetry. The method error was within 2mm and it seemed to be useful in preoperative planning for maxillofacial surgery with maxillo-mandibular occlusal change

PURPOSE: Tc-99m MIBI scintimammography has been validated as an useful non-invasive diagnostic tool for the primary breast cancer. But most studies have included small population of patients. We have experienced a large study population and investigated the diagnostie usefulness of Tc-99m MIBI scintimammography in detection of primary breast cancer and axillary Iymph node metastasis. MATERIALS AND METHODS: This study included 30S patients who underwent scintimammography for palpable breast masses or abnormal radiologic findings. Tc-99m MIRI scintirnammography was performed 10 minutes after intravenous injection of 925 MBq of Tc-99m MIBI. If the early image revealed abnormal finding, 3 hour delayed image was also acquired. We calculated early and delayed lesion to non-lesion ratios (L/N). The pathologic diagnosis was obtained from surgical operation or F.4AB and compared with the results of Tc-99m MIBI scintimammography. RESULTS: Malignant breast diseases were 155 and benign ones were 150. Tc-99m MIBI scintimammography revealed 132 true positive, 23 false negative, 10 false positive, and 140 true negative cases. The sensitivity, specificity, positive predictive value and negative predictive value for the primary breast cancer detection were 85.2%, 93.4%, 92.9%, and 85.9%, respectively. The sensitivity, specificity, positive predictive and negative predictive values of Tc-99m MIBI scintimammography in detecting metastatic axillary lymph node involvement were 22%, 90.4%, 61.9% and 62.3%, respectively. Early L/N of malignant breast disease was significantly higher than that of benign one (2,44+/-0.97 vs 1.94+/-0.78, p=0.01). Delayed L/N had no significant difference between malignant an Breast Diseases ; Breast Neoplasms* ; Breast* ; Diagnosis ; Humans ; Injections, Intravenous ; Lymph Nodes ; Neoplasm Metastasis ; Sensitivity and Specificity
