The purpose of the present study was to assess the usefulness of balloon expandable Palmaz intravascular stents in the transcatheter treatment of children and young adults with native and recurrent coarctation of the aorta, and to develop an improved intravascular stent and balloon delivery catheter specifically developed for vascular obstructions associated with congenital heart disease, inclu...

The use of self expandable metallic stents (SEMS) in the palliation of dysphagia due to malignant esophageal stenosis is a gold standard. Covered stents are used in all cases with overt air-digestive fistula or high potential for fistula development. The procedure is associated with a low incidence of procedure-related complications. We present a case with a major accident which developed durin...

In the last few years, there has been a growing focus on faster computational methods to support clinicians in planning stenting procedures. This study investigates the possibility of introducing computational approximations in modelling stent deployment in aneurysmatic cerebral vessels to achieve simulations compatible with the constraints of real clinical workflows. The release of a self-expa...

Carcinoma of the esophagus is the fifth commonest tumor in Pakistan 1 . The presentation is generally late with dysphagia even for liquids. Surgical results in these advanced cases are not very encouraging; therefore esophageal stents have been used to maintain the patency of the esophagus. These stents not only maintain the nutrition but also facilitate drainage of saliva and other secretions,...

The present study was intended to evaluate the acute and short-term hemodynamic, angiographic, and pathological response to balloon-expandable stent treatment of experimental coarctation of the aorta. A discrete thoracic coarctation was surgically created in six mongrel dogs (two adults, four puppies). Two months postoperatively all six dogs (8.9-30 kg) underwent left heart catheterization an...

BACKGROUND/AIMS There are limited data regarding the clinical outcomes of self-expandable metal stents in the treatment of proximal colon obstruction. We compared the clinical outcomes of stent placement in patients with malignant proximal to distal colon obstructions. METHODS We reviewed medical records from 37 consecutive patients from three institutions (19 men; mean age, 72 years) who und...

BACKGROUND Expandable metal stent insertion and thermal tumor ablation (TTA) both improve dysphagia in patients with advanced esophageal cancer, but no direct comparison study of their efficacy on health-related quality of life has been published. The aim of this study was to compare survival, relief of dysphagia, quality of life, and cost in patients treated by thermal ablation or stent insert...

BACKGROUND An aneurysm of the superior mesenteric artery (SMA) with a diameter of 2.2 cm was found incidentally on an ultrasound (US) examination in a 26-year-old woman. The only known risk factor was an intracranial aneurysm that was found on her grandmother's autopsy. Based on pregnancy planning and the current literature, endovascular management with a covered stent was proposed. CASE REPO...
