BACKGROUND AND PURPOSE Vessel recanalization is a strong predictor of good outcome in acute ischemic strokes (AIS) secondary to large vessel occlusions. We report our single-center experience with self-expandable stents in the treatment of AIS. METHODS The stroke database of Baptist Cardiac and Vascular Institute in Miami was retrospectively reviewed from August of 2008 to September of 2010. ...

In this paper a reversible watermarking method based on generalized integer transform of a vector with n pixels is presented. This method was firstly introduced by Alattar (called Alattar’s method) has been concerned and expanded because it can achieve high embedding capacity without losing the implication of the cover. According to Alattar’s method, n-1 bits could be embedded into a vector wit...

BACKGROUND AND PURPOSE Endovascular placement of coronary balloon-expandable stents in patients with recurrent cerebral ischemia has emerged as a treatment option for intracranial arterial occlusive disease. We have developed an in vitro model matching the tortuous curve of the carotid siphon that allows the assessment of apposition of stents to a curved vessel wall. METHODS Six types of ball...

PURPOSE To report our early experience with thermo-expandable urethral stents (Memokath) for the management of recurrent urethral stricture and to assess the efficacy of urethral stents. MATERIALS AND METHODS Between March 2012 and February 2013, 13 patients with recurrent urethral stricture after several attempts with direct visual internal urethrotomy (DVIU) or failed urethroplasty underwen...

Expandable endoprostheses have become an acceptable modality to address the issue of limb-length inequality in limb-sparing procedures for skeletally immature patients afflicted with lower extremity bone sarcomas. This study retrospectively analyzed postoperative outcomes and complications for 7 patients (8 limbs) who underwent minimally invasive or noninvasive reconstruction during a 12-year p...

Dysphagia is the most common presenting symptom in patients with esophageal malignancy and contributes significantly to weight loss and malnourishment. An increasing number of patients with locally advanced esophageal cancer undergo treatment with neoadjuvant chemoradiotherapy (CRT) before surgery because this has been shown to improve survival. Neoadjuvant CRT is, however, associated with acut...

AIM The purpose of this paper is to present our experiences with carotid artery stenting in the treatment of dissected carotid arteries, by means of self-expandable stents and selective employment of cerebral protection devices. METHODS In the period from June 1, 2006 to April 31, 2009, 6 patients with 6 dissected carotid arteries were treated with self-expandable stents (4 internal carotid a...

OBJECTIVE To evaluate the safety and effectiveness of a 20-mm diameter dual-design expandable colorectal stent for malignant colorectal obstruction. MATERIALS AND METHODS The study series included 34 patients with malignant colorectal obstruction who underwent implantation of a 20-mm dual-design expandable colorectal stent in our department between March 2009 and June 2010. The 20-mm dual-des...

Esophageal cancer with post-operative lymph node metastasis (LNM) compressing and infiltrating the trachea causing dyspnea is considered a serious complication. However, chemotherapy or radiotherapy are often ineffective methods for such patients. Approaches employing metallic expandable stents to relieve airway obstruction are extremely effective in advanced-stage cancer patients. The present ...

OBJECTIVES To assess the role of temporary thermally expandable urethral stents in maintaining urethral patency in patients with a recurrent bulbar urethral stricture. PATIENTS AND METHODS Twenty-three men with a recurrent bulbar urethral stricture after several attempts at direct visual internal urethrotomy (DVIU) and/or failed urethroplasty were managed with a thermally expandable, biocompa...
