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: Classically air in the portal vein has been detected on plain radiography, but computed tomography and ultrasonography have been shown to be more sensitive. We report a case of air in the PV in a 10-day-old infant with pneumatosis intestinalis with its ultrasonographic and Doppler findings. MATERIAL AND METHODS: The patient was a 10-day-old infant born by cesarean section at 41 weeks. Simple abdomen film revealed branching pattern of radiolucent air shadows within the contour of liver, gas distention of bowel loops and thickenod bowel walls with lincar intraluminal air shadows in abdomcn, suggesting neerotizing enterocolitis. So we performed Doppler ultrasonography. RESULTS: Ultrasonography showed branching pattern of hyperechogenic dots along the lumen of left portal vein. The color Doppler study revcaled an aliasing duo to increased velocity and whirling pattern of blood flow, and the Duplex Doppler spectral display showed sharp, vertical bidirectional spikes by air in portal vein. CONCLUSION: Air in the portal voin can be easily diagnosed by the followign signs:hyperechogenic dots in the portal vein on ultrasonography and vertical, sharp bidirectional spikes superimposod on the usual Doppler tracing of the portal vein on Duplex ultrasonography.
