Diana Y Kircheva, Wickii T Vigneswaran
INTRODUCTION: Spontaneous esophageal rupture is rare, roughly 300 cases reported annually. Diagnosis is often delayed or missed. Overall mortality is about 20%. This feared high mortality rate has led to the misconception that primary esophageal repair should be avoided in late diagnosed patients. We report a successful primary repair of spontaneous esophageal rupture which was delayed for more than two weeks. METHODS: A 53 year-old male presented to our medical service after falsely having been treated for pneumonia at an outside hospital...

This article presents the results of endoscopic treatment for recurrent postcorrosive esophageal stenosis with a tube-stent developed at our institution. The tube-stent was implanted in 5 children with corrosive esophageal injury at the age of 2 to 8.5 years after 7 to 64 dilatation sessions during 5 to 118 months. In total, 13 tube-stents were implanted. One patient had undergone 9 procedures during 2.5 years and the tube-stent remained in place for 14 to 250 days. This patient was tube-stent-dependent due to the lack of any possibility of surgical reconstruction...

Men with either chronic or temporary urinary retention symptoms are common patients treated in a urology practice. Both indwelling and intermittent catheterization are widely used to treat this condition. These approaches are associated with significant complications including infection and reduced quality-of-life. Infection is a target for quality improvement and cost reduction strategies in most care settings today. We use a temporary prostatic stent (TPS) to address these issues in our practice. In this report, we describe our approach to patient selection, sizing, placement and follow up of 214 TPS placed in 56 men with chronic or temporary urinary retention in an office setting...

INTRODUCTION: Surgical site infection [SSI] is a risk for any surgical procedure, including hypospadias repair. Prophylactic antibiotic therapy for patients having surgery is often effective in preventing SSIs, but with increasing rates of antibiotic resistance, this practice has been questioned. The objectives of this study are 1) to assess the incidence of SSIs in patients following stented, distal hypospadias repair and 2) to observe for any potential difference in the incidence of SSIs for patients with and without preoperative antibiotic utilization in this setting...

Background Ureteral arterial fistulas are rare but potentially life threatening. We present a female who developed a ureteral arterial fistula following a right robotic nephrectomy. After several endovascular interventions to control the bleeding had failed, we approached the fistula through the right ureteral stump with coil embolization. Methods Coil embolization of the right ureteral stump was performed. We utilized a 6Fr × 45 cm sheath inserted through one of the cystoscope channels to cannulate the right ureteral orifice...

Zhengze Dai, Gelin Xu
As a common etiology for ischemic stroke, atherosclerotic carotid stenosis has been targeted by vascular surgery since 1950s. Compared with carotid endarterectomy, carotid angioplasty and stenting (CAS) is almost similarly efficacious and less invasive. These advantages make CAS an alternative in treating carotid stenosis. However, accumulative evidences suggested that the long-term benefit-risk ratio of CAS may be decreased or even neutralized by the complications related to in-stent restenosis (ISR). Therefore, investigating the mechanisms and identifying the influential factors of ISR are of vital importance for improving the long-term outcomes of CAS...

Acute concomitant occlusions of the extracranial internal carotid artery and intracranial vessels frequently require multiple passes with stent-retrievers for mechanical thrombectomy. Due to the large clot burden associated with these occlusions, their response to intravenous thrombolysis is poor. We herein report a successful case of evacuating a massive clot (>14 cm) in a single-pass using a stent-retrieval device.

The aim of this study was to evaluate the inhibitory effect of sirolimus coating on the occurrence of restenosis and thrombosis with heparinized stents. Heparin and dopamine were conjugated by chemical bonding and anchored on the stent surface by a mussel-inspired adhesion mechanism. Subsequently, sirolimus was coated with poly lactic-glycolic acid on the heparinized stent surface. The heparin was well attached to the surface, and the surface was smooth after sirolimus coating. The smoothness of the surface was maintained after expansion of the stent...

Conflicting evidence exists on gender differences in outcomes after coronary stenting, and gender-based data in patients with chronic total occlusions (CTO) who underwent percutaneous coronary intervention (PCI) are scarce. Consecutive patients who underwent CTO PCI from January 2005 to December 2013 were included in the analysis and stratified according to gender. The primary outcome measure was all-cause mortality. Median follow-up was 2.6 years (interquartile range 1.1 to 3.1). Of 2002 patients, 332 (17%) were women...

This review analyzed the incidence, mechanisms, and risk factors of aortic-related reintervention after endovascular repair of chronic dissections. The systematic review identified 28 studies describing 1,249 patients at median 27 months follow-up (range, 10.3 to 64.4). There were six reinterventions, 0.7 ruptures, and 1.2 surgical conversions per 100 patient-years of follow-up. Stent-related reinterventions were more frequent than nonstent related (80.2% vs 19.8%). Distal false lumen perfusion was the most common complication (40...

BACKGROUND: We describe the histopathology of an un-ruptured, giant calcified left MCA fusiform aneurysm initially treated with endovascular flow diversion. The flow diversion construct underwent post-operative in-stent thrombosis, necessitating surgical resection of the aneurysm to eliminate mass effect. METHODS: A 75-year-old woman with a known left MCA aneurysm presented to the Emergency Department with moderate right hemibody weakness. Due to the clinical and radiographic progression of the aneurysm, the patient was offered treatment...

This paper presents a strain-mediated phenomenological corrosion model, based on the discrete finite element modelling method which was developed for use with the ANSYS Implicit finite element code. The corrosion model was calibrated from experimental data and used to simulate the corrosion performance of a WE43 magnesium alloy stent. The model was found to be capable of predicting the experimentally observed plastic strain-mediated mass loss profile. The non-linear plastic strain model, extrapolated from the experimental data, was also found to adequately capture the corrosion-induced reduction in the radial stiffness of the stent over time...

BACKGROUND: Systemic treatment with sirolimus, as used for immunosuppression in transplant patients, results in markedly low rates of in-stent restenosis. Since the underlying mechanisms remain obscure, we aimed to determine the molecular and cellular effects of systemic sirolimus treatment on vascular remodeling processes. METHODS AND RESULTS: Systemic sirolimus treatment significantly reduced smooth muscle cell (SMC) proliferation 14days after wire-induced injury and neointima formation 28days after injury in C57BL/6 mice, while simultaneously impairing re-endothelialization...

Few randomized controlled trials (RCTs) and observational studies had shown acceptable short-term efficacy and safety of percutaneous coronary intervention (PCI) with drug-eluting stents (DES) compared with coronary artery bypass grafting (CABG) in selected patients with left main coronary artery disease (LMCAD). We aimed to evaluate long-term outcomes of PCI using DES compared with CABG in patients with LMCAD. On November 1, 2016, we searched available databases for published RCTs directly comparing DES PCI with CABG in patients with LMCAD...
