OBJECTIVES We evaluated the anatomic and technical factors predicting stent malposition and embolization in patients undergoing endovascular stent implantation for relief of noncoronary vascular obstruction. BACKGROUND Endovascular stent implantation provides a highly effective, minimally invasive solution to vascular obstruction in patients with structural heart disease. However, stent impla...

Background Patients with post-thrombotic syndrome due to chronic venous obstruction and resistant to conservative management can benefit from endovenous revascularization. The current study investigated the usefulness of duplex ultrasound in monitoring the stent changes over the time. Method All duplex ultrasound images of treated patients were reviewed retrospectively. The stent diameter and a...

We describe a case of successful open-cell stent deployment across the wide neck of a large middle cerebral artery aneurysm using the stent anchor technique. A microcatheter was looped through the aneurysm and navigated into a distal vessel across the aneurysm neck. Although the loop of the microcatheter in the aneurysm straightened as it was gently withdrawn, the microcatheter again protruded ...

BACKGROUND Intraluminal tracheal stenting is a minimally invasive procedure shown to have variable degrees of success in managing clinical signs associated with tracheal collapse syndrome (CTCS) in dogs. OBJECTIVES Identify immediate post-stent changes in tracheal diameter, determine the extent of stent migration, and stent shortening after stent placement in the immediate-, short-, and long-...

A 72-year-old man with a heavily calcified coronary lesion underwent percutaneous coronary intervention (PCI) using a third-generation drug-eluting stent (DES) with thin stent struts. Two months after the PCI, in-stent restenosis due to stent recoil (SR) occurred. An intravascular ultrasound (IVUS) revealed deformed stent struts and heavily calcified coronary plaque. The SR probably occurred du...

The purpose of this study is to clarify the clinical usefulness of Gianturco-Z stent (G-Z stent) for the management of malignant and benign tracheobronchial stenosis. Seventy-three stents were used in 30 patients. In 20 cases, we used the so-called "stent-in-stent" method. Twenty-four patients were grade 5, and 6 were grade 4 according to the Hugh-Jones classification of respiratory status. The...

Abstract Background Caudal tracheal stent migration can be potentially life threatening by causing distal luminal obstruction. We present a rare double hitch stitch procedure (for prevention of stent), which is an external fixation technique in case tracheoesophageal fistula with and esophageal self-expandable metallic (SEMS). Case presentation A 50-year-old male patient who presented cough dys...

A 64-year-old male with unstable angina underwent direct stenting in the proximal and mid-left anterior descending coronary artery (LAD) lesions. Although coronary angiography showed a good result, intravascular ultrasound imaging revealed a dissection flap protruding through the struts of the stent in the proximal LAD. Another stent was deployed in the first stent (stent-in-stent) to seal it. ...

The majority of percutaneous coronary intervention cases are performed using drug eluting stents. Trials have consistently demonstrated lower rates of in stent restenosis and repeat revascularization with drug eluting stents when compared with bare metal stents. Stent technology has improved over the decade with changes in the thickness of stent struts, polymer coating and ease of stent deliver...
