High-speed rotational atherectomy of bilateral ureter stenosis.
A60-year-old woman was hospitalized for oliguria with bilateral impediment of both renal pelvises. Bilateral nephrostomies were necessary. Twelve months earlier, two titanium stents (Engineers & Doctors) had been implanted in the distal parts of both ureters because of diffuse ureteral stenosis after irradiation therapy for cervical carcinoma 17 years earlier. At admission, retrograde pyelograp...
متن کاملTreatment of calcific coronary stenosis with the use of excimer laser coronary atherectomy and rotational atherectomy
Noncrossable and nondilatable coronary lesions pose a major concern in percutaneous coronary intervention (PCI) often leading to technical failure, incomplete revascularization and complications. With the increasing age of the PCI population and the increasing complexity of cases undertaken in many centers, ‘balloon failure’ is now encountered more frequently. Such calcified stenosis, chronic t...
متن کاملDetailed angiographic analysis of high-speed mechanical rotational atherectomy in human coronary arteries.
BACKGROUND Several types of atherectomy devices have been developed recently for treatment of patients with ischemic heart disease. METHODS AND RESULTS Mechanical rotational atherectomy (MRA) using a high-speed rotational burr (Rotablator) was performed on 116 lesions in 104 patients. MRA alone was performed in 27 lesions (23%), and conventional balloon angioplasty (PTCA) was performed after ...
متن کاملRotational atherectomy: an Update
As we known, drug-eluting stents (DES) reduce the risk of restenosis and represent an important advance in coronary intervention. Newer-generation DES with thin struts releasing limus-family drugs from durable or biodegradable polymers have further improved clinical outcomes, as compared with early-generation DES releasing sirolimus or paclitaxel. The risk of stent thrombosis has become exceedi...
متن کاملRotational atherectomy: Technical update.
Percutaneous coronary intervention is currently the most common form of revascularization for symptomatic coronary artery disease. In elderly, diabetic and renal patients, there is an increased prevalence of calcified coronary disease. Rotational atherectomy (RA) can be useful in the treatment of these lesions. Plaque removal was initially proposed as an alternative to balloon angioplasty, henc...
