mycotic aortic aneurysms account for 1–3% of all aortic aneurysms. the management of this disease is controversial. since open surgical repair is associated with high morbidity and mortality rates, endovascular aneurysm repair is an alternative treatment method with promising early and midterm outcomes, although its long-term durability is unknown. secondary aortoenteric fistulas may occur iatr...

PURPOSE Radioactive stents have been proposed as endovascular irradiation device to prevent in-stent restenosis by inhibiting neointimal proliferation. 32P-stents have been used in several studies so far, but require large-scale labeling procedures and endovascular barotrauma for stent expansion supporting the development of edge restenosis. Purpose of this study was to establish dosimetry of a...

PURPOSEImage-guided adaptive brachytherapy (IGABT) recently has shown excellent clinical outcomes with superior local control and less toxicity. For IGABT, T2W (T2-weighted) MRI is the gold standard. However, studies have that target delineation same results in uncertainties, poor interobserver variabilities, low conformity indices for high-risk volume contours. In this study, we investigate ro...

 Abstract Traumatic descending thoracic aorta pseudo aneurysms have been treated traditionally with open surgery in the past, which have had noticeable rates of mortality and morbidity. A safer method of treatment for this disease is made possible with recent progress in endovascular treatment techniques. In this article, we present three cases of Traumatic descending thoracic aorta pseudo aneu...

Brachytherapy reduces the post radiation sequalae as dose required is lower than external beam therapy (EBRT) and limits area of exposure. This case report outlines two different patients managed by fabrication carrier prosthesis for duration brachytherapy.

Background: Recent pre-clinical and clinical studies indicate that irradiation in the dose range of 15 to 30 Gy can reduce rate of restenosis in patients who have undergone an angioplasty. The use of filled balloon with radioactive solution was proposed as one of the possible intravascular irradiation techniques. Materials and Methods: The Monte Carlo N-particle Transport Code (MCNP4b) was used...

introduction in this study, we aimed to calculate dose enhancement factor (def) for gold (au) and iron (fe) nanoparticles (nps) in brachytherapy and teletherapy, using monte carlo (mc) method. materials and methods in this study, a new algorithm was introduced to calculate dose enhancement by aunps and fenps for iridium-192 (ir-192) brachytherapy and cobalt-60 (co-60) teletherapy sources, using...

Background: Toxicity assessment is done by comparing HDR brachytherapy with ICRU point doses. D2cc doses of OAR in slightly more than Objectives:The primary objective volumetric dose and toxicity comparison between brachytherapy. Materials Methods: It a prospective comparative study. The total number patients enrolled the study 20. After obtaining informed consent, then were All diagnosed H.P.E...

BACKGROUND We reviewed the outcomes of oropharyngeal squamous cell carcinoma treated with external beam radiation and interstitial brachytherapy. METHODS Ninety patients with squamous cell carcinoma of the oropharynx were treated with interstitial brachytherapy at the University of Utah between 1984 and 2001. Seventy-two patients received external beam radiotherapy (EBRT) followed by brachyth...

OBJECTIVE The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. METHODS Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information...
