Periscope endograft technique to revascularize the left subclavian artery during thoracic endovascular aortic repair.
2013
To present early and midterm results of the periscope endograft (PG) technique to maintain left subclavian artery (LSA) blood flow in thoracic endovascular aortic repairs (TEVAR) involving zone 3.From April 2010 to January 2013, 14 consecutive high-risk patients (11 men; mean age 70±8 years, range 56-87) underwent TEVAR with the PG technique for 10 thoracic aortic aneurysms (TAA), 2 traumatic aortic ruptures, and 2 aortic dissections without a suitable landing zone (2 cm distal to the LSA). Five procedures were performed emergently for rupture (3 TAAs and the 2 trauma cases). Two patients had a periscope deployed in an aberrant right subclavian artery. The periscope endografts were sized 1 …
Treating iliac aneurysm using the Nellix Endovascular Sac Sealing System.
2016
As endovascular treatment of abdominal aortic aneurysms has become established, there has been growing focus on treatment of the aneurysmal iliac artery. Isolated, large iliac aneurysms >30 mm pose a risk of rupture, but, in addition, 20% to 30% of abdominal aortic aneurysms are associated with iliac aneurysmal dilatation, which can compromise long-term outcomes. Endovascular solutions are evolving and until recently have utilized standard stent graft technology. The endovascular aortic sealing system was introduced as a new, effective method for the treatment of infrarenal aortic aneurysms. In this article, we present our recent extended use of the Nellix system, with or without a combinat…
Use of covered chimney stents for pararenal aortic pathologies is safe and feasible with excellent patency and low incidence of endoleaks.
2012
Background To present the clinical experience of consecutive series with use of balloon-expandable and self-expanding chimney endografts (balloon-expandable covered stent group [BECS] vs self-expanding covered stent group [SECS]) in the endovascular treatment of challenging aortic pathologies requiring renal and/or visceral revascularization. Methods Between January 2009 and May 2011, data for 37 high-risk patients from one center and 35 patients from another institution, with pararenal aortic pathologies treated by the chimney endovascular technique, were prospectively collected. The chimney-graft technique is based on the deployment of a covered or bare-metal stent parallel to the aortic …
9-Month Clinical and Angiographic Outcomes of the COBRA Polyzene-F NanoCoated Coronary Stent System
2016
Abstract Objectives The aim of this study was to assess the safety and effectiveness of the COBRA Polyzene-F NanoCoated Coronary Stent System (CeloNova Biosciences, San Antonio, Texas) for the treatment of de novo coronary artery lesions. Background Polyzene-F–coated coronary stents have shown reduced thrombogenicity and inflammation in preclinical studies. Methods Patients with de novo coronary artery lesions meeting eligibility criteria were enrolled in a nonrandomized, prospective clinical trial. The primary endpoint was target vessel failure (TVF) (defined as a composite of cardiac death, myocardial infarction, or clinically driven target vessel revascularization) at 9 months. A pre-spe…
Bioresorbable polymer-coated thin strut sirolimus-eluting stent vs durable polymer-coated everolimus-eluting stent in daily clinical practice: Propen…
2018
Objectives We sought to determine the 1-year clinical follow-up in patients treated with the thin strut (71 μm) bioabsorbable polymer-coated sirolimus-eluting stent (BP-SES) vs durable coating everolimus eluting stent (DP-EES) in daily clinical routine. Background Presence of durable polymers may be associated with late/very late stent thrombosis occurrence and the need for prolonged dual antiplatelet therapy. Bioabsorbable polymers may facilitate stent healing, thus enhancing clinical safety. Methods Interventional Cardiology Network Registry is a prospective, multicenter, observational registry of 21,400 consecutive patients treated with PCI since 2010. We analyzed 4,670 patients treated …
Early outcomes with a single-sided access endovascular stent
2018
Abstract Objective The objective of this study was to report the 1-year follow-up study results of the new Horizon stent graft (Endospan, Herzliya, Israel) from two different prospective consecutive trials. The Horizon abdominal aortic aneurysm stent graft system is a 14F profile system requiring only a single access site. It consists of three modules, introduced separately: base limb (iliac to iliac limb); distal aortic limb; and proximal aortic limb with a bare suprarenal crown and active fixation. Methods Data from the first in man (FIM) clinical study with 10 patients enrolled and the pivotal study with 30 patients were analyzed. Outcomes measured were freedom from major adverse events …
Risk Factors for Failure of Male Slings and Artificial Urinary Sphincters: Results from a Large Middle European Cohort Study.
2016
<b><i>Introduction:</i></b> We analysed the impact of predefined risk factors: age, diabetes, history of pelvic irradiation, prior surgery for stress urinary incontinence (SUI), prior urethral stricture, additional procedure during SUI surgery, duration of incontinence, ASA-classification and cause for incontinence on failure and complications in male SUI surgery. <b><i>Materials and Methods:</i></b> We retrospectively identified 506 patients with an artificial urinary sphincter (AUS) and 513 patients with a male sling (MS) in a multicenter cohort study. Complication rates were correlated to the risk factors in univariate analysis. Subsequentl…
The TiLOOP® Male Sling: Did We Forejudge.
2017
<b><i>Introduction:</i></b> To evaluate the safety and efficacy of the TiLOOP® male sling (pfm medical, Cologne, Germany) used in the treatment for male stress urinary incontinence (SUI). <b><i>Material and Methods:</i></b> We retrospectively evaluated a total of 34 patients with a TiLOOP® male sling. Perioperative complication rates were assessed and validated questionnaires were prospectively evaluated to assess quality of life and satisfaction rate. Outcome and complication rates were analysed by using descriptive statistics. Correlation of continence outcome and risk factors was performed with the chi-square test. A <i>p</i> va…
Initial Clinical Experience Using the Low-Profile Altura Endograft System With Double D-Shaped Proximal Stents for Endovascular Aneurysm Repair.
2018
Purpose: To report the initial clinical results of endovascular aneurysm repair (EVAR) using the low-profile (14-F) Altura Endograft System, which features a double “D-shaped” stent design with suprarenal fixation and modular iliac components that are deployed from distal to proximal. Methods: From 2011 to 2015, 90 patients (mean age 72.8±8.3 years; 79 men) with abdominal aortic aneurysm (AAA; mean diameter 53.8±5.7 mm) were treated at 10 clinical sites in 2 prospective, controlled clinical studies using the Altura endograft. Outcomes evaluated included mortality, major adverse events (MAEs: all-cause death, stroke, paraplegia, myocardial infarction, respiratory failure, bowel ischemia, an…
The Gore Hybrid Vascular Graft in renovisceral debranching for complex aortic aneurysm repair.
2016
Objective This study reports our initial experience with the Gore Hybrid Vascular Graft (GHVG; W. L. Gore & Associates, Flagstaff, Ariz) for staged hybrid open renovisceral debranching and endovascular aneurysm repair in patients affected by thoracoabdominal aortic aneurysms and pararenal abdominal aortic aneurysms (PAAAs). Methods Between December 2012 and December 2013, we analyzed outcomes of 13 patients who underwent open surgical debranching of renovisceral vessels for thoracoabdominal aortic aneurysm and PAAAs. All patients were considered at high risk for conventional surgery. Inclusion criterion was treatment by open surgical debranching of at least one visceral artery (renal artery…
