Objective: Any treatment of tracheo–esophageal fistulae in end-stage malignant stenosis of the esophagus must be weighed against associated morbidity and mortality. In a prospective study we investigated benefits and risks of the use of one type of coated, self-expandable stent. Patients and methods: We treated four male and two female patients, (mean age 68.3 years, range: 38–90 years), with m...

INTRODUCTION This study aimed to evaluate the feasibility of total endovascular repair of the aortic arch in pigs using improved integrated double-branched stent grafts. METHODS Improved self-expandable stent grafts with a main body and two integrated branches were prepared for the repair of the aortic arch in six pigs. The feasibility of using these stent grafts was evaluated with arteriogra...

Coronary artery aneurysm is a relatively uncommon disorder characterized by coronary artery dilatation with diameter that exceeds 50% of the normal adjacent segments with atherosclerosis being the most common etiology. Aneurysms can be adjacent to a stenosis in a post- or prestenotic location. Both anatomical conditions are technically challenging regarding their percutaneous treatment because ...

D uring the past 10 to 15 years, fractures of implanted metallic stents in various vascular and nonvascular beds have been reported. deVries et al reported fracture of a stent graft placed in the carotid artery of a 59-year-old man to treat a traumatic pseudoaneurysm 7 months after implantation.1 Carrozza reported recurrence of symptoms due to the fracture of a balloon-expandable stent placed a...

BACKGROUND Intact or highly restricted intra-atrial septum can be reliably diagnosed in the human fetus as early as 22 to 24 weeks of gestation. Fetal interventions targeting the atrial septum have used a direct approach through the atrial wall. Here, we report stenting of the foramen ovale with a large, open-cell stent via percutaneous access through the fetal hepatic vein in a sheep model. ...

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 ...

BACKGROUND To present perioperative and long-term results of percutaneous treatment of adult isthmic coarctation of the aorta by means of a self-expandable closed-web uncovered nitinol stent (Sinus-XL, Optimed, Esslingen, Germany). METHODS AND RESULTS Preoperative, perioperative, and long-term clinical and computed tomographic angiography data were collected and analyzed prospectively. A tota...

able esophageal stents provide a new alternative in the treatment of patients with benign refractory esophageal stenoses. Despite encouraging preliminary results published in a small series of case reports [1–4], potential complications of biodegradable stents, like those seen with self-expandable plastic stents (SEPS) and self-expandable metallic stents (SEMS), have not been addressed yet. We ...

S34 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 with a snare and introduce it into the duodenoscope, passing through it a papilotome. Then, we perform a conventional ERCP with a self-expandable stent. Evolution was satisfactory DOI: 10.4103/2303-9027.212361

The endovascular treatment of wide-necked intracranial aneurysms is evolving. We report our initial experience in treating seven wide-neck intracranial aneurysms by using a new self-expanding stent, the Neuroform, in combination with a new generation of coils that incorporate a self-expandable hydrophilic lining, the HydroCoil.
