in the recent years, interstitial brachytherapy implantation has become the treatment of choice for early stage prostate cancer patients. treatment of prostate cancer with radiation is traced back to 1909. originally this treatment modality was very crude and could not gain much popularity till 1982. advancements in radioactive source designs, introduction of new low energy radioactive sources,...

The invention of the drug-eluting stent (DES) has brought about revolutionary changes in the field of interventional cardiology. In the DES era, in-stent restenosis has declined but new issues such as stent thrombosis have emerged. One of the emerging paradigms in the DES era is stent fracture. There are reports about stent fracture leading to in-stent restenosis or stent thrombosis. Most of th...

Stent migration from the delivery balloon catheter is a rare but serious complication during percutaneous coronary intervention, particularly when a part of the stent stretches into the aorta. We report an unusual case of stent migration treated with a combination of a gooseneck snare and rotablation. A part of the stent was overstretched and unrolled into the aorta and the rest of the stent re...

Although the favored strategy for coronary bifurcation intervention is stenting main vessel with provisional side branch (SB) stenting, we occasionally use two-stent strategy. The objective of this study was to investigate the angiographic outcome of SB ostium in two-stent group, compared with one-stent group. We analyzed 199 patients with bifurcation lesion who underwent percutaneous coronary ...

BACKGROUND Self-expandable stents loaded with 125I (iodine 125) seeds may combine the advantages of the immediate relief of esophageal dysphagia with stent placement and radiation therapy with brachytherapy. We compared the self-expanding irradiation stent with a conventional self-expandable covered stent in patients with malignant dysphagia due to recurrent esophageal cancer. METHODS The pat...

Here, we present a case of 56-year-old man with acute myocardial infarction. The patient underwent percutaneous coronary intervention (PCI) at the left main bifurcation and mid-left anterior descending artery using drugeluting stents. Four months after PCI, was readmitted for cardiac arrest. Coronary angiography (CAG) revealed stent thrombosis in main-toproximal in-stent restenosis circumflex a...

BACKGROUND Intravascular ultrasound (IVUS)-guided stent implantation and the availability of a reference chart to predict the expected in-stent restenosis rate based on operator-dependent IVUS parameters may interactively facilitate optimal stent placement. The use of IVUS guidance protects against undue risks of dissection or rupture. METHODS AND RESULTS IVUS-determined post-stent-implantati...

1. NATIONAL FRAMEWORK FOR MANAGEMENT AND REGULATION OF RADIOACTIVE WASTE AND DECOMMISSIONING 1.1 National framework 1.1.1 Overview of national policy The Atomic Energy Commission (AEC) of the Korean government developed the “National Radioactive Waste Management Policy” at the 249 th meeting held on September 30, 1998. The policy stipulates that the site selection process for radioactive waste ...

BACKGROUND AND STUDY AIMS The treatment success of benign biliary strictures with fully covered metal stents (CSEMS) is altered by high stent dislocation rates. We aimed to evaluate a new stent design to prevent dislocation. PATIENTS AND METHODS Patients with benign biliary strictures were treated with a newly designed double-coned stent (dcSEMS). Mechanical analysis of the new stent was perf...
