AbstractObjectivesWe aimed to compare the procedural and mid-term performance of a specifically designed self-expanding stent with balloon-expandable stents in patients undergoing hybrid palliation for hypoplastic left heart syndrome and its variants.BackgroundThe lack of specifically designed stents has led to off-label use of coronary, biliary, or peripheral stents in the neonatal ductus arteriosus. Recently, a self-expanding stent, specifically designed for use in hypoplastic left heart syndrome, has become available.MethodsWe carried out a retrospective cohort comparison of 69 neonates who

Abstract:

The objectives of central venous percutaneous transluminal angioplasty are to dilate the venous lesion and to extend the life of arteriovenous fistula for hemodialysis. It is reasonable to perform percutaneous transluminal angioplasty for central venous lesions if this interventional therapy is required to maintain stable dialysis therapy. However, the presence of large fresh thrombus at central venous lesion site represents a contraindication to percutaneous transluminal angioplasty unless the thrombus can first be removed by thrombectomy. Balloon angioplasty is a basic treatment for central

Abstract:

The management of aortoiliac insufficiency has been improved considerably since the introduction of balloon-expandable stents in 1991. Although numerous studies have shown the safety and efficacy of balloon-expandable iliac artery stent placement, the procedure is not without potential complication. We report here a very unusual case of iliac artery stenting being complicated by deformation and elongation of the stent following balloon rupture at initial deployment with retention of the distal balloon marker and our successful approach to subsequent management with combined acetylsalicylic aci

Purpose: To describe a method for dealing with balloon rupture during stent deployment. Technique: A 10-mL Luer-Lock syringe containing contrast material and heparinized saline is used to re-expand a balloon ruptured during stent deployment, permitting maximum balloon expansion and successful initial stent-wall apposition. No adjunctive use of probing catheters or a power injector is necessary to achieve adequate stent expansion. Analysis of the rupture may identify procedural deficiencies that can be rectified. Conclusions: This technique is simple and timesaving, and interventionists should

AbstractThe kink behavior of vascular stents is of particular interest for clinicians, stent manufacturers and regulatory as a kinked stent generates a lumen loss in the stented vessel and can lead to in-stent restenosis. In this study methods to determine the kink resistance of stents and stent delivery systems according to the ISO 25539-2 and FDA guidance no. 1545 were presented. The methods are applicable for balloon expandable stents as well as for self-expanding stents and determine the lumen loss and residual diameter change dependent on the specific bending radius.

Atherosclerosis is one of the major types of cardiovascular diseases. Stent deployment into the stenosed artery is the most common treatment for atherosclerosis. Two common stent models based on two different expansion principles are balloon-expandable and self-expandable stents. Depending on the modality of the expansion, the material used for these two stents varies. Despite the extensive progress made in the field of stent construction, plaque fragmentation and in-stent restenosis are two of the problems that still cause complications in stenting.

Abstract:

A stenotic vessel can be opened using net-shape tubes called “stents” leading to the restoration of the bloodstream. Compared to the commonly used stainless steel stent, self-expandable stents have some advantages. They do not suffer from the risks of damage to the vascular tissue due to the balloon expansion. Moreover, overexpansion for compensating the elastic recoil is not needed, and there is no constant force applied on the artery until the occlusion of the device by the artery stops. However, the stent cannot restore the original dimensions of the vessel in the case of calcif

There is a clinical need to develop a stent to treat obstructive and refractory Eustachian tube dysfunction (ETD) after balloon Eustachian tuboplasty. An animal model for stent placement in the Eustachian tube (ET) is needed to develop optimal designs and materials, as stents for ETD have not been clinically applied. The purpose of this study was to evaluate the technical feasibility of stent placement and histological changes in a porcine ET model. Six ETs were evaluated in three pigs. Cobalt–chrome alloy stents with two different diameters were placed in the left and right ET of each animal

Abstract:

We evaluated the feasibility of stenting in four patients. Two cases were vertebral osteal stenosis and the others were carotid stenosis at high position with ulcers. We placed balloon expandable coronary stents by a bared stent technique. The mean preprocedural stenosis (86.58%) was reduced to 13.05%. Patients were examined clinically and angiographically at 1, 3 and 6 months after stenting. There was no minor nor major stroke during and after the procedures. Asymptomatic restenosis occurred in the cases of proximal vertebral arteries. One of these patients needed to repeat balloon dilatation

Abstract:

Objective: Recurrent cerebral ischemic events are estimated to appear in between 12-15% of symptomatic intracranial atherosclerotic disease (ICAD), regardless of the use of leading pharmacological therapies. Balloon expandable stent (balloon mounted coronary stent) could represent a feasible alternative in this disease’s treatment. This study pretends to report the balloon-expandable placement experience in our center. Materials and Methods: A unicentric retrospective study dated between September 2009 and March 2018 was conducted. Patients previously diagnosed with ICAD and symptomatic stenos

Abstract:

Atherosclerotic stenosis of the posterior circulation refractory to medical treatment generally has a poor prognosis resulting in a high morbidity-mortality rate and the recurrence of ischemic events. Extracranial bypass in the vertebrobasilar system is possible but is also associated with high morbidity (3–21%) and mortality (13–55%)1,2, and has not been demonstrated to reduce the risk of stroke. Percutaneous angioplasty alone has also not shown favorable results, and further, has been associated with a remarkable number of complications.

Abstract:

A new expandable artificial heart valve was developed for implantation by a transluminal catheter technique without using thoracotomy or extracorporeal circulation. The aim of this study was to implant the valve in isolated vessels of the descending thoracic aorta as well as in closed chest pigs, and furthermore to study the prosthesis’ mechanical stability and the valve function. The artificial valve was made by mounting a porcine aortic valve on an expandable stent. Before implantation, the stent-valve was compressed on a deflated balloon catheter and mounted inside an introducer sheath. Aft

AbstractRecurrent esophageal stenosis secondary to caustic ingestion may be challenging to treat. Self-expandable esophageal stents may be an alternative to repetitive endoscopic esophageal dilatation. We report a case of a 2-year-old male child with an extensive esophageal caustic stricture successfully treated using a combination of endoscopic dilatation and stenting. After 5 months of serial balloon dilatations, three nitinol internal silicone covered self-expandable stents were placed through the patient’s gastrostomy spanning the entire esophagus.

Abstract:

Recently, the demand for a bio-absorbable coronary stent to promote recovery after an operation has increased. An option for such a stent is one made of a magnesium alloy, which has biodegradable properties. However, magnesium alloys have lower rigidity and lower ductility than other metals; as such, an appropriate stent structure is required to ensure radial rigidity. In this study, design parameters for an AZ31 magnesium alloy stent with sufficient radial rigidity were investigated. The necessary radial rigidity was determined by comparison tests against commercially available stents. The de
