#1
Daniel Pérez-Fentes
The creation of the access is one of the main steps in percutaneous nephrolithotomy, the most complicated for many urologists and the one that limited most the universalization of the technique. From a purely technical point of view, it includes puncture of the excretory tract and dilatation of the percutaneous tract to end with the introduction of an Amplatz type working sheath. The objective of the puncture is to try to access the excretory system through the renal papilla, minimizing the risk of bleeding...

AIMS: Surgical endarterectomy is the therapy of choice for atherosclerotic common femoral artery (CFA) obstruction. Recently, some large single-centre series have shown encouraging results for the percutaneous treatment of CFA obstructions. The purpose of this study was to evaluate the safety, feasibility, and one-year efficacy of the endovascular treatment of CFA obstructions with combined use of directional atherectomy (DA) and a paclitaxel-coated balloon (DCB). METHODS AND RESULTS: Between January 2012 and July 2014, 30 consecutive patients with severely calcified obstructions of the common femoral artery were treated in our centre using DA followed by DCB dilatation...

BACKGROUND: Left-sided cardiac obstructions represent 15% of congenital heart disease (CHD). The treatment in adults is surgical; however, balloon dilation by interventional catheterization can alleviate the symptoms in pediatric patients to allow them to reach the target height. The aim was to determine the survival and the factors associated with reintervention in patients with CHD with left-sided obstruction treated with balloon angioplasty. METHODS: A cohort study was conducted in patients aged 4 to 17 years with left-sided heart obstruction (valvular stenosis [VS], supravalvular aortic stenosis [SAS], coarctation of the aorta [CA]) successfully treated with balloon angioplasty...

BACKGROUND/AIMS: Endoscopic balloon dilation (EBD) can serve as an alternative to surgery for intestinal stenosis associated with Crohn's disease (CD). However, there has been controversy regarding the efficacy and safety of EBD. Here we sought to determine the therapeutic efficacy and safety of EBD for intestinal stenosis in CD. MATERIALS AND METHODS: Of 43 patients with CD accompanied by intestinal stenosis, 30 underwent EBD. These 30 patients were examined retrospectively in terms of the scope passage rate, surgery-free rate, and whether or not the observation of the distal intestinal tract influenced the therapeutic strategy...

BACKGROUND: The right gastroepiploic artery is commonly used in coronary artery bypass grafting. Appropriate strategies are required when performing upper abdominal surgeries after the right gastroepiploic artery has been used in coronary artery bypass grafting because compressing or injuring the graft may cause myocardial ischemia and fatal arrhythmias. To our knowledge, this is the first reported case of surgery for achalasia performed after coronary artery bypass grafting using the right gastroepiploic artery...

Eosinophilic esophagitis (EoE) is a clinicopathological condition of the esophagus that has become increasingly recognised over the last decade. EoE represents a chronic immune-mediated inflammatory disease of the esophagus. In adults dysphagia is the predominant symptom. Upper gastrointestinal endoscopy is required in order to take biopsies from the esophagus. The diagnose is confirmed histologically by typical eosinophilic infiltration of the esophagus mucosa. Until now there is no approved therapy world-wide although we know that topic and systemic steroids are highly effective in EoE...

Posttracheostomy tracheal stenosis is a rare complication of prolonged tracheal intubation. Treatment modalities that may be used include surgical resection and anastomosis, endoscopic tracheal dilation, laser resection, and tracheal stenting. We describe a novel salvage modality for dilation of a symptomatic tracheal stenosis using a percutaneous tracheostomy dilator wherein rigid bronchoscopic dilation was not feasible and balloon tracheal dilation had failed.

PURPOSE: Human amniotic epithelial cells (hAECs) are promising tools for endothelial repair in vascular regenerative medicine. We hypothesized that these epithelial cells are capable of repairing the damaged endothelial layer following balloon injury of the carotid artery in adult male rats. RESULTS: Two days after injury, the transplanted hAECs were observed at the luminal side of the arterial wall. Then, 4 weeks after the injury, significant intimal thickening was observed in both untreated and cell implanted vessels...

BACKGROUND: In stent design optimization, the functional relationship between design parameters and design goals is nonlinear, complex, and implicit and the multi-objective design of stents involves a number of potentially conflicting performance criteria. Therefore it is hard and time-consuming to find the optimal design of stent either by experiment or clinic test. Fortunately, computational methods have been developed to the point whereby optimization and simulation tools can be used to systematically design devices in a realistic time-scale...
