BACKGROUND: The management of blunt thoracic aortic injury (BTAI) has evolved radically in the last decade with changes in the processes of care and the introduction of thoracic endovascular repair (TEVAR). These changes have wrought improved outcome, but the direct effect of TEVAR on outcome remains in question as previous studies have lacked vigorous risk adjustment and long-term follow-up. To address these knowledge gaps, we compared the outcomes of TEVAR, open surgical repair, and nonoperative management for BTAI...

Limited data exist on clot composition and detailed characteristics of arterial thrombi associated with large vessel occlusion in acute ischemic stroke. Advances in endovascular thrombectomy and related imaging modalities have created a unique opportunity to analyze thrombi removed from cerebral arteries. Insights into thrombus composition, etiology, physical properties and neurovascular interactions may lead to future advancements in acute ischemic stroke treatment and improved clinical outcomes. Advances in imaging techniques may enhance clot characterization and inform therapeutic decision-making prior to treatment and reveal stroke etiology to guide secondary prevention...

Mammalian sterile 20-like kinase 1 (MST1) is found to promote neuronal apoptosis. Protein-L-isoaspartate (D-aspartate) O-methyltransferase (PCMT1), an anti-apoptosis factor, was recently identified as an MST1-interacting protein. This study aims to explore the potential role of PCMT1 in reducing MST1-induced neuronal apoptosis after subarachnoid hemorrhage (SAH) in rats. One hundred ninety-eight male Sprague-Dawley rats were used. An exogenous PCMT1 agonist, CGP 3466B, was injected subcutaneously 1 h after the SAH induced by endovascular perforation...

Metallic zinc implanted into the abdominal aorta of rats out to 6 months has been demonstrated to degrade while avoiding responses commonly associated with the restenosis of vascular implants. However, major questions remain regarding whether a zinc implant would ultimately passivate through the production of stable corrosion products or via a cell mediated fibrous encapsulation process that prevents the diffusion of critical reactants and products at the metal surface. Here, we have conducted clinically relevant long term in vivo studies in order to characterize late stage zinc implant biocorrosion behavior and products to address these critical questions...

BACKGROUND: Acute Ischemic Stroke (AIS) treatment has been revolutionised in the last two decades with the increasing use of Intravenous Thrombolysis (IVT) and with the advent of Endovascular therapy (EVT). AIS treatment and outcome are time dependant and time saving measures are being implemented at every step of the treatment chain. These changes have resulted in lower treatment times in-hospital, but it is unclear if this translates into more patients being treated within 60 min of symptom onset - the Golden Hour...

Background: The presence of extracranial carotid disease (ECD) is associated with less favorable clinical outcomes a in patients with acute ischemic stroke caused by intracranial proximal occlusion. Acute intra-arterial treatment (IAT) in the setting of extracranial and intracranial lesions is considered challenging, and whether it yields improved outcomes remains uncertain. Objective: To examine whether the presence of ECD modified the effect of IAT for intracranial proximal anterior circulation occlusion...

The dual microcatheter technique is an alternative treatment for stent-assisted coiling in acutely ruptured wide-necked aneurysms because of no antiplatelet therapy. We assessed the safety and efficacy of this technique in ruptured wide-necked aneurysms. Between March 2008 and March 2016, 56 acutely ruptured aneurysms were treated with the dual microcatheter technique. The angiographic results, treatment-related complications, and clinical outcome were documented. Angiographic follow-up was available in 37 patients at a mean of 20...

In the current era, endovascular treatment of long femoropopliteal lesions (>15 cm) is becoming more feasible and favorable, with patency rates that rival surgical outcomes. Drug-coated balloons offer promising results at least to one year follow up although randomized, controlled trials to evaluate its efficacy compared to other treatment modalities (surgical and endovascular alike) is lacking at this time.

Interventional radiology (IR) has become an integral part in the management of traumatic injuries. There is an ever-increasing role of IR in traumatic injuries of solid abdominal organs, pelvic and peripheral arteries to control active bleeding by therapeutic embolization or vascular reconstruction using stent grafts. Traditionally, these endovascular treatments have been offered to hemodynamically stable patients. However, in recent times endovascular approach has become preferable to surgery even in hemodynamically unstable patients with injury of surgically difficult-to-access sites...

INTRODUCTION: Infected femoral pseudoaneurysms are a common presentation in intravenous drug users with little consensus as to the optimum management of these patients. Whilst emergency revascularisation options are available, excision and ligation of the femoral artery remains the most common operative intervention but risks leaving the patient with critical ischaemia or intermittent claudication. This case series reviewed the outcomes of 4 patients who underwent excision-ligation without revascularisation of an infected femoral pseudoaneurysm at a district general hospital...

We describe the use of percutaneously inserted, transcatheter endovascular graft prostheses to exclude large Mustard baffle leaks in a high-surgical-risk patient. We used 3-dimensional-printed models to determine feasibility and to plan the procedure. Telescoping thoracic and abdominal graft extensions were placed in the inferior and superior limbs of the systemic venous pathways. An atrial septal defect occluder device was also used to close a separate leak not covered by the endovascular graft prostheses...

Acute ischemia in chronic type B dissections carries high rates of morbidity and mortality. A 29-year-old woman with a chronic type B dissection presented with acute abdominal pain. Imaging revealed a worsening dissection with pseudocoarctation causing near complete occlusion of the true lumen by the false lumen. We placed purposefully undersized stent grafts to treat acute mesenteric ischemia by improving true lumen flow. The patient was discharged on postoperative day 4 without adverse events. We suggest that endovascular rescue by placing undersized stent grafts can provide improved flow to the mesenteric vessels with continued false lumen flow to vital organs...
