Endoluminal retrieval of foreign bodies in the pediatric and infant population is an uncommon and challenging procedure for the endovascular specialist. The alternative is an open exploration of these often-fragile patients. The availability of smaller catheter systems allows retrieval with minimally invasive techniques. We report retrieval of a catheter fragment using an Amplatz loop snare through the umbilical vein and review the literature.
The safety and efficacy of a contemporary series of CA performed in vascular surgery practice compared favorably with recognized interdisciplinary quality standards for this procedure. Ensuring safe and effective CA is likely to support the successful growth of CAS as a treatment option.
Aneurysms of saphenous vein grafts (SVGs) to coronary arteries are rare, usually asymptomatic and found incidentally. We report a case of an 84-year-old female who was found to have 8.1 × 8.4 cm aneurysm of an SVG to obtuse marginal (OM) artery. The aneurysm was prior to the distal anastamosis but no flow into the OM artery was noted. Cook Tornado Embolization Coils were used successfully to occlude the SVG proximal to the aneurysm. No complications occurred. The use of embolization coils is an effective and safe method for aneurysm occlusion when the anatomy is suitable and especially when patient is high risk for repeat surgical intervention.
Technologic advances in percutaneous catheter-based therapy for renovascular occlusive disease have resulted in progressively miniaturized wires, balloon catheters, stents, and delivery systems. The technique of angioplasty and stenting of renal artery stenoses has been shown to be a safe and effective option for severe hypertension and ischemic nephropathy. Renal artery stenting, especially when performed with the newer lower-profile systems, can be performed with minimal morbidity and a reliably high degree of initial technical success. In this article, we describe our technique using a lower-profile platform of balloons and stents and review data supporting renal artery stenting.
Venous stents (VS) are used to treat central and peripheral stenoses. Stent embolization into a cardiac chamber is a rare, yet serious complication. We present a case of a 61-year-old man with a recently stented arteriovenous graft venous stenosis who developed VS migration into the right ventricle, associated with S. aureus bacteremia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
