Protective stent

N Laube, F Bernsmann, C Fisang
Urological implants in the urinary tract are routinely used to ensure urine flow. However, the morbidities are numerous concerning long-term derivations. Especially with the ureteral stents, failure can have considerable consequences. Since the surfaces of all urological implants are more or less ideal substrates for microorganisms, the formation of bacterial biofilms is a regularly observed and often serious complication, which in many cases forces early implant replacement. The burden on the patient and the health system are enormous...

BACKGROUND AND OBJECTIVES: Neurologic intolerance (NI) is defined as the occurrence of neurological symptoms during carotid artery stenting (CAS). Because NI is inevitable problem, it may be helpful to anticipate its occurrence. So, we studied factors associated with NI during proximal protected CAS. METHODS: We retrospectively analyzed all consecutive patients underwent proximal protected CAS from August 2012 to January 2017. RESULTS: We included total 123 patients (109 males, 72±8 years old)...

Treatment of pseudoaneurysms in the internal carotid artery (ICA) is associated with a high risk of cerebral infarction; therefore, vessel ligation for hemostasis must be avoided. A 66-year-old man had intraoral hemorrhaging. At the time of the initial examination, computed tomography angiography showed jaw plate displacement near the ICA. A more detailed image was obtained using digital-subtraction angiography. After evaluation of the image, a pseudoaneurysm was diagnosed. Six days later, there were concerns about aspiration and airway obstruction; therefore, tracheostomy was performed...

The use of double layer (covered) stents during carotid artery stenting (CAS) appears to be safe; attenuation of plaque prolapse and distal embolization is reasonable but unproven. Double layer stents are commercially available in Europe but not in the United States; similar benefits might be obtained by implanting two self-expanding stents, to decrease the effective free cell area. Embolic protection devices (EPDs) are recommended in all CAS patients; the use of double layer stents does not eliminate the need for EPDs...

OBJECTIVE: Proximal embolic protection devices (P-EPD) and distal filters (DF) are used to prevent distal cerebral embolizations during carotid artery stenting (CAS). We compared their comparative effectiveness in regards to prevention of intraprocedural and periprocedural adverse events, including ischemic lesions (ipsilateral and contralateral), stroke, transient ischemic attacks (TIA) and death. We also compared the combination of the two neuroprotection strategies vs. a single strategy in regards to ischemic lesions and stroke...

Uncovered self-expandable metallic stents (USEMS) are superior to plastic stents in patients with unresectable malignant perihilar biliary obstruction (UMHBO)1 . The causes of SEMS occlusion include: tumor ingrowth/mucosal hyperplasia, tumor overgrowth, sludge with/without stone, hemobilia, food impaction, bile duct kinking, ulceration, perforation, and fibrin clots2-3 . We present a rare case of ultra-early occlusion of the normal bile duct after USEMS placement for UMHBO. This article is protected by copyright...

BACKGROUND: Crossing a nascently deployed carotid artery stent (CAS) is required to perform angioplasty and filter recapture. If the traversing balloon or filter recapture catheters are eccentric or tangentially angled to the vertical axis of the CAS they can ensnare on the ledge of the proximal CAS step-off, potentially causing life-threatening complications secondary to deformation, displacement, or mechanical occlusion of the stent. We report a novel "balloon bridge" technique that facilitates safe entry and passage across the CAS with both a balloon catheter and an LBGC...

PURPOSE: Initial stenotic occlusion of the internal carotid artery (ICA) with intracranial artery occlusion in acute ischemic stroke is associated with high morbidity and can benefit from endovascular therapy. However, the optimal endovascular strategy is unclear. This study aimed to evaluate the feasibility of the "half" anterograde approach and clinical outcome of treated patients. Revascularization validity of the two "half" anterograde approach with (PEARS technique) or without (plain technique) using an embolic prevention device and aspiration was also compared...

BACKGROUND: Carotid artery stenting (CAS) with proximal occlusion effectively prevent distal cerebral embolism by flow arrest at internal carotid artery (ICA); however, the method can expose antegrade flow at ICA due to incomplete flow arrest. The aim of this study was to identify predictors of antegrade flow during CAS with proximal protection. METHODS: We retrospectively analyzed clinical and angiographic data among 143 lesions treated with CAS with proximal protection by occluding the common carotid artery (CCA) and external carotid artery (ECA)...

Carrier-free drug eluting stents (DES) based crystalline coatings are gaining prominence due to their function, skipping many limitations and clinical complications of the currently marketed DES. However, their usage has been humbled by crystalline coating inflexibility, limited mechanical and physical properties. This study reports for the first time a protective top coating development for enhancing crystalline coating merits and delivery capabilities. Flexible and water soluble polysaccharide top coating was developed and applied onto Rapamycin (RM) crystalline carpet...
