The risk of in-stent restenosis has been dramatically reduced with the use of thin-strut nitinol and balloon-expandable drug-eluting stents in the peripheral arterial territory. However, the presence of a permanent endovascular device is linked to a series of events that can lead to restenosis and stent thrombosis. Significant advances in ...

Recurrent in-stent-stenosis by tissue overgrowth is a common problem for esophageal stents and may be cumbersome to treat by conventional methods. Cryoextraction is a well-established technique within the trachea-bronchial tree for obtaining large biopsies (cryobiopsy) and for recanalization (cryorecanalization), but has not been used in the gastrointestinal tract. We report ...

Endovascular aneurysm repair is now the preferred method of abdominal and thoracic aneurysm repair. Until recently, the limitation with this technology has been preservation of the visceral vasculature, hypogastric arteries, and the great vessels. The Zenith® Fenestrated (Cook, Bloomington, IN) is the first device available for use in the US ...

The aortic valve operates in a complex haemodynamic environment, opening and closing over 100,000 times a day. When complications arise, such as aortic stenosis, prognosis can be very poor, leading to death within the first few years. Surgical valve replacement is currently the standard treatment for aortic stenosis. A thorough ...

Successful surgical treatment of cerebral aneurysms requires complete occlusion of the aneurysm lumen while maintaining patency of the adjacent branching and perforating arteries. Intraoperative flow assessment allows aneurysm clip repositioning in the event these requirements are not met, avoiding the risk of postoperative rehemorrhage or infarction. A number of modalities ...

Restenosis is the major drawback in patients undergoing tibial angioplasty. In contrast to earlier observations, tibial patency was shown to impact on clinical outcomes in current randomized trials and is thus attributed more importance. Accordingly, intentions to reduce tibial restenosis have been intensified. Both drug-eluting balloons (DEB) and drug-eluting stents ...

Coronary balloon angioplasty and coronary stenting are the procedures used in healing coronary artery disease. However, injury of arteries during angioplasty and stenting causes cell stimulations in tissue. Cell movement and thrombosis lead to re-narrowing of widened vessel called restenosis. Several new types of carriers and technology have been developed ...

Coronary angiography falls short in accurately delineating anatomy of epicardial vessels as it provides only a two-dimensional visualization of the lumen.(1) Moreover, angiographic lesion assessment is impeded in cases of diffuse disease of reference vessels, lesion foreshortening and eccentricity as well as overlap of several arterial branches. Conversely, intravascular ultrasound ...

Carotid occlusive disease is one of several etiologic factors for stroke. Of all strokes, an estimated 88% are ischemic in nature. Less than 20% of these are caused by atheroma in the carotid bifurcation. Traditionally, carotid artery stenosis has been treated with carotid endarterectomy (CEA); however, carotid artery balloon angioplasty ...

Coil migration during endovascular treatment of intracranial aneurysms occurs in 2-6% of cases. As endovascular coiling of aneurysms has become increasingly popular and as endovascular technology continues to rapidly evolve, the prevalence of intraprocedural coil migration will invariably rise. Since coil masses are highly thrombogenic, migration out of the aneurysm ...
