Endoscopic reintervention for stent malfunction after stent-in-stent deployment for malignant hilar obstruction

Endoscopic bilateral stenting has been increasingly performed for advanced hilar obstruction. As disease progresses, stent malfunction eventually occurs. However, endoscopic reintervention is difficult in these patients. We aimed to evaluate a suitable reintervention procedure for stent malfunction after stent-in-stent (SIS) deployment for malignant hilar obstruction.Among 52 patients with bila...

Carotid Artery Stent Continued Expansion Days After Deployment, Without Post Stent Deployment Angioplasty

This is a carotid artery stent (CAS) case report, which avoids post-stent deployment angioplasty (Post-SDA), with duplex confirmed continued stent expansion at 1, 3 and 30-day post deployment. This report confirms that self-expanding nitinol stents in the carotid artery may not require Post-SDA. We believe CAS can be performed without Post-SDA, which helps reduce the occurrence of intraoperativ...

Optimization of Stent Deployment by Intravascular Ultrasound

Intravascular ultrasound (IVUS) is a useful diagnostic method that provides valuable information in addition to angiography regarding the coronary vessel lumen, dimensions, plaque burden, and characteristics. The major use of IVUS in coronary intervention is to guide interventional strategies and assess optimal stent deployment. Since the introduction of the drug-eluting stent (DES), concerns a...

Plaque Excision and Stent Graft Deployment for SFA Occlusion

M anagement of superficial femoral artery (SFA) occlusive disease remains one of the great challenges for peripheral endovascular therapy. Failure of percutaneous balloon angioplasty as a result of residual luminal narrowing or dissection is a frequent occurrence, especially in patients with calcified lesions, long stenoses, or occlusions.1 The implantation of nitinol stents for treatment of va...
