A prospective randomised trial comparing plastic and uncovered self-expanding metal stents for palliation of symptomatic jaundice in patients with malignant distal biliary obstruction
… clinical effectiveness of 10Fr plastic biliary stents compared to uncovered self-expanding metal stents (SEMS) for palliative treatment of patients with inoperable malignant distal biliary obstruction in a public hospital in South Africa. Methods: From January 2009 to December 2013, 40 patients …

Eine Stentimplantation außerhalb der FDA-Indikationen für DES ist unabhängig von der Wahl des Stenttyps mit einer erhöhten Stentthromboserate verbunden
For decades, implantation of stents in coronary lesions after baloon dilatation has been the gold standard therapy in stenotic coronary artery disease. With the use of bare-metal stents, the cardiologist often saw an instent restenosis, which led to the invention of drug-eluting-stents. …

Langzeituntersuchung zur In-Stent-Restenose eines neuen biodegradierbaren, wirkstoffbeladenen, intravaskulären Polylaktidstents nach Implantation in porcine Koronararterien
… of instent restenosis and permanent nature of metal stent implants, synthetic polymers have been proposed as surrogate materials for stents and local delivery systems for drugs. Paclitaxel was shown to inhibit vascular smooth muscle cell proliferation and migration. A novel biodegradable …

Development of bioabsorbable braided vascular scaffolds for the intracranial circulation
… in aneurysm treatment was the advent of the metal flow-diverting stent, which made it relatively easy to treat the most complicated of brain aneurysms, and avoiding the need for a high-risk open surgical procedure. Despite these improvements, metal stents are still associated with major …

Application Of In Vivo Flow Profiling To Stented Human Coronary Arteri
… after being treated separately with bare metal stents (BMS) and Sirolimus Eluting Stents (SES). The stent assignments were blinded until the end of the study. The study was repeated for the patients after 9 months. The predicted WSS ranged from (0.1- 8 N/m2) and was categorized into five …

Evaluation der endoskopischen im Vergleich zur operativen Gastroenterostomie bei Patienten mit maligner Magenentleerungsstörung
… ermöglicht die Entwicklung der Lumen-apposing-Metal Stents (LAMS) die endosonographische Gastroenterostomie. Diese schafft eine transluminale Verbindung zwischen Magen und Dünndarm, mit Umgehung der Stenose und stellt eine minimalinvasivere Alternative zur L-GE dar. In der vorliegenden …

Construction of nano-assembled microcapsules embedded with gold nanoparticles for use in novel drug delivery systems
Coronary stents have changed the way in which coronary artery diseases are managed. Although bare-metal stents can be traced back to 1994, long term efficacy of these stents has been shattered by ISR (In-Stent restenosis) and late stent thrombosis. Research on finding a solution to these issues has …

A system for impedance characterization of coronary stents
Stents are used to re-open and maintain flow in diseased coronary arteries in patients suffering from coronary heart disease. Drug-eluting stents are now the preferred choice of stent but their performance is still limited by delayed healing of the important endothelial cell layer that lines the …

Vergleichende Untersuchung zur Nutzung von Paclitaxel-beschichteten-Stents und unbeschichteten Stents zur Behandlung stenosierter Venenbypässe
… and angiographic success of drug-eluting stents in saphenous vein grafts. This multicenter study sought to define the follow-up clinical and angiographic results after implantation of paclitaxel-eluting stents (PES) in stenotic saphenous vein grafts in comparison to treatment using bare …

Evaluation eines Tacrolimus-beschichteten Stents zur Prävention der Restenosierung im diabetischen Tiermodell
… Recently, a number of studies using drug-eluting stents have been performed, since the local and sustained application of antiproliferativ drugs can achieve a decrease in restenosis rates. Tacrolimus, a Rapamycin-derivative, owns, as an immunsuppressiv drug, antiinflammatoric as well as …

Bioactive surfaces for improved coronary stent performance
Drug eluting stents (DES) are widely used to treat coronary heart disease. Although current DES generally perform well, restenosis and delayed endothelium healing still remains an issue following stent implantations. Research efforts are now focused on the development of stent coatings that address …

Characterization and Implementation of a Decellularized Porcine Vessel as a Biologic Scaffold for a Blood Vessel Mimic
… angioplasty procedures in combination with a metal stent often result in successful restoration of normal blood flow. However, bare metal stents often lead to restenosis and other complications. To compensate for this problem, industry has created drug-eluting stents to promote healing of the …

Promoting endothelialisation to reduce vascular injury following coronary angioplasty and stent implantation
… that promote endothelialisation of coronary stents. Furthermore, I evaluated the potential of a novel cyclin-dependent kinase (CDK) inhibitor (AT7519) to resolve the acute neutrophil-mediated inflammatory response to stenting without adversely affecting the function and integrity of the …

Η χρήση των εμποτισμένων με φάρμακα μεταλλικών ενδοπροθέσεων στον ουρητήρα πειραματικού μοντέλου
Οι εμποτισμένες με φάρμακα μεταλλικές ενδοπροθέσεις (DES) έχει αποδειχθεί ότι ελαχιστοποιούν την υπερπλασία του ενδοθηλίου των στεφανιαίων αγγείων. Η υπερπλαστική αντίδραση του ουροθηλίου είναι το πιο συχνή επιπλοκή της χρήσης των μεταλλικών ενδοπροθέσεων στον ουρητήρα. Στην παρούσα μελέτη …

An analysis of prognostic, endoscopic and transjugular intrahepatic portosystemic salvage shunting factors influencing rebleeding and death in portal hypertensive patients with life-threatening variceal bleeding
… methods including self-expanding oesophageal metal stents and improved quality PTFE-coated TIPS stenting are anticipated to improve bleeding control and survival in this high-risk cohort. Several important and unresolved issues relating to the specific role of sTIPS in the management of …
