BACKGROUND: The "very late" clinical outcomes for durable polymer drug-eluting stents and bare metal stents (BMSs) have been shown to be dissimilar in clinical studies. Conceptually, the long-term vascular compatibility of BMSs is still regarded to be superior to drug-eluting stents; however, no pathologic study to date has specifically addressed this issue. We evaluated the very late (≥1 year) pathologic responses to durable polymer drug-eluting stents (cobalt-chromium [CoCr] everolimus-eluting stents [EESs] and stainless steel sirolimus-eluting stents [SS-SESs]) versus BMSs (CoCr-BMSs)...

BACKGROUND/PURPOSE: Endoscopic retrograde cholangiopancreatography (ERCP) is an adjunct for pediatric pancreatic injury management, but its use and utility in pediatric patients are unclear. We set out to evaluate the use of ERCP and its effects on outcomes. METHODS: A retrospective review was performed for children who had pancreatic injuries at 22 pediatric trauma centers between 2010 and 2015. ERCP details and outcomes were collected. Analysis was performed using descriptive statistics and Wilcoxon rank-sum tests...

Aortic aneurysms are life-threatening conditions with effective treatments mainly limited to emergency surgery or trans-arterial endovascular stent grafts, thus calling for the identification of specific molecular targets. Genetic studies have highlighted controversial roles of transforming growth factor β (TGF-β) signaling in aneurysm development. Here, we report on aneurysms developing in adult mice after smooth muscle cell (SMC)-specific inactivation of Smad4, an intracellular transducer of TGF-β. The results revealed that Smad4 inhibition activated interleukin-1β (IL-1β) in SMCs...

BACKGROUND: The use of a ureteral stent can cause a urinary tract infection (UTI), although it reduces urologic complications. UTIs are associated with a higher rate of ureteral stent colonization (USC). The aim of this study was to compare USC in living and deceased donor renal transplant recipients. MATERIAL AND METHODS: We conducted a prospective study of 48 patients who underwent renal transplantation between January and December 2016. The stents were removed aseptically, the inner surface of proximal and distal ends of stents were irrigated with liquid culture medium, and then they were vortexed for bacteriological investigation...

BACKGROUND: Urinary tract infections (UTIs) are the commonest infectious complication in kidney transplant recipients (KTRs). No recommendations exist regarding treatment of asymptomatic bacteriuria. We aimed to identify potential risk factors and microbiological profile for UTIs, the role of treatment of asymptomatic bacteriuria, and effects on graft outcomes of bacteriuria within the first year post-transplantation. METHODS: We performed a retrospective analysis of UTIs in KTRs transplanted between January 2012 and December 2013 in 2 transplantation centers...

BACKGROUND: Only surgically irrelevant risk factors including sex, African-American ancestry, or exceptional U-stitch anastomosis have been identified to associate with urinary complications after kidney transplantation. The objective was to identify modifiable and nonmodifiable risk factors associated with urinary complications after kidney transplantation. METHODS: A single-center study of 3,129 kidney transplants performed over 40 years was conducted to identify independent risk factors using χ(2) tests and logistic regression analysis...

OBJECTIVES: Heart valve replacement with a bioprosthesis is one of the most frequently performed procedures in cardiac surgery and represents a highly effective therapy to relieve diseased heart valves. Nevertheless, as postoperatively elevated transvalvular gradients and prosthesis-patient mismatch are reported as shortcomings of the procedure or of the currently used devices, there is a need for novel bioprostheses with improved haemodynamics. This study presents preclinical haemodynamic results after mitral valve replacement with the novel TRIBIO bioprosthesis (TRIBIO) compared with an established bioprosthesis in a sheep model...

Cerebral hyperperfusion syndrome (CHS) is a serious complication following carotid artery stenting (CAS), but definitive early prediction of CHS has not been established. Here, we evaluated whether indocyanine green kinetics and near-infrared spectroscopy (ICG-NIRS) with hyperventilation (HV) and the breath-holding (BH) test can predict hyperperfusion phenomenon after CAS. The blood flow index (BFI) ratio during HV and BH was prospectively monitored using ICG-NIRS in 66 patients scheduled to undergo CAS. Preoperative cerebrovascular reactivity (CVR) and the postoperative asymmetry index (AI) were also assessed with single-photon emission computed tomography before and after CAS and the correlation with the BFI HV/rest ratio, BFI BH/rest ratio was evaluated...

Recurrent coarctation postoperative Norwood is poorly tolerated in single ventricle patients. Although transcatheter balloon angioplasty is considered first line, it often leads to inadequate or non-durable relief of obstruction. Transcatheter stent implantation provides excellent relief of obstruction but necessitates staged redilation to account for somatic growth in children. Stent technology, delivery systems, and procedural techniques will need to evolve to obviate reported adverse events mainly due to patient size...

Stent thrombosis and clinically driven restenosis are rare in the era of newer generation DES. The Synergy bioresorbable polymer DES appears to be comparable to other durable polymer and other bioabsorbable polymer DES in terms of safety and efficacy at 1-year post implantation. Further long-term study is needed to determine the specific role of the Synergy stent and other DES with bioabsorbable polymers.

BACKGROUND: Malignant dysphagia can result in poor nutritional status with severe weight loss. Rapid relief from dysphagia can be achieved with esophageal self-expanding metal stents (SEMSs), a minimally invasive method. In this study, we evaluated the usefulness of SEMSs for malignant dysphagia. METHODS: Between 2012 and 2015, 119 patients with malignant dysphagia underwent esophageal SEMS insertion with endoscopic assistance. Their demographics and clinical outcomes were collected...

Drug-eluting stents have significantly improved the long-term outcomes of percutaneous coronary intervention (PCI) by decreasing the excessive growth of neointima. However, conventional stents have some limitations. PCI with a bioresorbable vascular scaffold (BVS) has emerged as an alternative since the presence of the prosthesis in the coronary artery is transient. A US Food and Drug Administration advisory panel of experts recommended approval of BVS based on the analysis of its risks and rewards in July 2016...

Herein, we report a rare case of type B aortic dissection that occurred after endovascular aortic aneurysm repair (EVAR). A 66-year-old man underwent successful EVAR for an abdominal aortic aneurysm (AAA). Computed tomography (CT) 2 years after EVAR showed a type B aortic dissection with stent-graft migration and AAA expansion. Juxtarenal aortic expansion precluded simple stent-graft placement. He underwent hepato-spleno-renal bypass followed by stent-graft placement just below the superior mesenteric artery...

Persistent sciatic artery (PSA) is a rare anomaly that may cause various symptoms, such as aneurysm, rupture, thromboembolism, and sciatica. Direct surgery can be performed to treat PSA aneurysm (PSAA), but is associated with complications; e.g., anatomical problems such as sciatic nerve injury. Herein we report a case of a 74-year-old woman with acute limb ischemia that developed from a distal embolism caused by a thrombus in the left PSAA; favorable results were obtained for her by treatment with a stent-graft after rapid anticoagulation therapy for limb salvage...

Isolated abdominal aortic dissection (IAAD) is a rare form of aortic dissection involving usually the infrarenal part of the abdominal aorta. A 45-year-old male presented with lumbar pain and claudication. Computed tomography angiography (CTA) revealed an infrarenal IAAD extending to the left external iliac artery (EIA), causing ≥90% narrowing of the lumen. An endovascular approach was decided, with deployment of an aortic stent-graft and two balloon expandable stents in both common iliac arteries (IAs), applying the kissing stents technique...

During aneurysm clipping, ischemic complications may occur and require a rescue treatment, usually surgical. We present two such cases that required urgent rescue treatment, performed through an endovascular route. Our first case presented with a non-ruptured right posterior inferior cerebellar artery (PICA) aneurysm. After permanent clip positioning, occlusion of the PICA occurred. An unsuccessful attempt of clip repositioning was performed. We therefore positioned a stent obtaining complete flow restoration...
