BACKGROUND Aortic occlusion, whether acute or subacute, is a rare but very serious entity with disastrous consequences if not treated in a timely fashion. Rapid diagnosis is crucial in this setting. In surgically treated patients there is a high degree of mortality and morbidity; therefore, percutaneous revascularization, whenever possible and independent of the available techniques, is much more desirable. CASE REPORT A 62-year-old woman with a history of diabetes mellitus, dyslipidemia, hypertension, and peripheral vascular disease, with previous femoral-femoral bypass for right common iliac artery occlusion, and with recent conventional angiography showing near occlusion of the ostial left common iliac artery (the donor vessel for the previous bypass), was referred to our hospital for conventional angioplasty...

OBJECTIVE: Proximal neck dilation is a serious long-term complication directly causing the failure of endovascular aneurysm repair (EVAR) and open surgical repair (OSR) of abdominal aortic aneurysms. However, the implantation of a fenestrated device presents the opportunity for proximal extension of the aortic reconstruction into a healthy segment while maintaining patency of the visceral vessels. The objective of this investigation was to report perioperative and follow-up outcomes using the Zenith Fenestrated (ZFEN; Cook Medical, Bloomington, Ind) aortic stent system in salvaging previous aortic repairs undergoing type IA endoleak or aneurysmal degeneration of the proximal neck...

OBJECTIVE: to determine impact of different laboratory and genetic factors on high on-treatment platelet reactivity (HOPR) during dual antiplatelet therapy (DAPT). METHODS: We included in this study 94 patients with stable ischemic heart disease (mean age 59±9.67 years). All patients underwent elective PCI with implantation of drug eluting stents at the background of dual antiplatelet therapy (DAPT) with aspirin and clopidogrel. Platelet reactivity was assessed using light transmission aggregometry with 5 μmol/L ADP (LTA 5ADP) and VerifyNow assay before PCI...

Current guidelines recommend that percutaneous coronary intervention (PCI) should be restricted to the culprit vessel in ST elevation myocardial infarction (STEMI) patients with multi-vessel disease (MVD) and without cardiogenic shock. However, newer data suggests that performing complete revascularization (CR) in MVD patients may lead to better outcomes compared to intervention in the culprit vessel only. The aim of this meta-analysis is to examine the available data to determine if CR (using either angio- or fractional flow reserve guidance-FFR) following primary PCI in STEMI patients without cardiogenic shock impacts clinical outcomes...

PURPOSE: Fusion of preoperative data with intraoperative X-ray images has proven the potential to reduce radiation exposure and contrast agent, especially for complex endovascular aortic repair (EVAR). Due to patient movement and introduced devices that deform the vasculature, the fusion can become inaccurate. This is usually detected by comparing the preoperative information with the contrasted vessel. To avoid repeated use of iodine, comparison with an implanted stent can be used to adjust the fusion...

The treatment of coronary bifurcations is challenging for interventional cardiologists. The Tryton stent (Tryton Medical, Inc., USA) is one of the few devices specifically designed for coronary bifurcations that underwent large clinical trials. Although the manufacturer provides specific recommendations to position the stent in the bifurcation side branch (SB) according to four radio-opaque markers under angiographic guidance, wrong device positioning may accidentally occur. In this study, the virtual bench testing approach was used to investigate the impact of wrong positioning of the Tryton stent in coronary bifurcations in terms of geometrical and biomechanical criteria...

Three cases of internal carotid artery (ICA) injury during endoscopic endonasal surgery were analyzed, including 1 case of recurrent malignancy of sphenoid sinus, 1 case of intraorbital meningioma and 1 case of optic neuropathy. Salvage sphenoid sinus packing with gauze strip was managed in all the three cases. One patient operated a permanent closure of the carotid system intraoperatively and died after surgery. Among 2 survival cases, one patient accepted the endovascular embolization subsequently; the other patient was cured by intravaseular stent graft implantation without craniocerebral or ocular complicatitms...

BACKGROUND: We hypothesise that a comprehensive optical coherence tomography (OCT)-guided implantation protocol for bioresorbable scaffolds (BRS) might improve expansion and apposition, thus translating into better clinical outcomes, particularly reducing thrombotic events. METHODS: Patients considered suitable for BRS therapy in de novo coronary lesions underwent OCT. The predominant type of plaque was classified as lipidic, fibrous or calcific, undergoing tailored plaque preparation accordingly...

An ideal vascular stent would both inhibit in-stent restenosis (ISR) and promote rapid re-endothelialization. In the current study, the performance of arsenic trioxide (ATO)-drug eluting stent (AES) is compared with the bare metal stent, poly-lactic-co-glycolic acid-coating metal stent, and rapamycin-drug eluting stent (RES). In vivo AES is shown to prevent neointimal hyperplasia more efficiently than the others when implanted into the carotid arteries of rabbits. Moreover, AES promotes endothelial cells proliferation and re-endothelialization more quickly than RES...

We present the case of a fistula between the trachea and the esophagogastric anastomosis in a 58-year-old male after esophagectomy. A Hem-o-Lok clip used at the time to ligate the azygos vein was discovered by esophagoscopy and bronchoscopy to be eroding into the both structures. A covered self-expandable Y-shaped metallic tracheobronchial stent was customized with a 3D printed airway model and inserted in place, with endoscopic injection of fibrin glue to the anastomotic site. 64 days after implantation, the stent was withdrawn with complete healing of the fistula...

Objectives: Stent implantation for the treatment of aortic coarctation has become a standard approach for the management of older children and adults. Criteria for optimal stent design and construction remain undefined. This study used computational modelling to compare the performance of two generations of the Cheatham-Platinum stent (NuMED, Hopkinton, NY, USA) deployed in aortic coarctation using finite element analysis. Design: Three-dimensional models of both stents, reverse engineered from microCT scans, were implanted in the aortic model of one representative patient...

OBJECTIVES/HYPOTHESIS: Current techniques for airway characterization include endoscopic or radiographic measurements that produce static, two-dimensional descriptions. As pathology can be multilevel, irregularly shaped, and dynamic, minimal luminal area (MLA) may not provide the most comprehensive description or diagnostic metric. Our aim was to examine the utilization of computational fluid dynamics (CFD) for the purpose of defining airway stenosis using an ovine model of tissue-engineered tracheal graft (TETG) implantation...
