We present the case of a 48-year-old woman with an acute type A aortic dissection that was treated with thoracic endovascular aortic repair at our institution. The patient was found to have a focal type A dissection with pericardial effusion but no tamponade physiology and no involvement of the aortic valve or root. We elected to treat the patient's type A aortic dissection with an endovascular stent because of the patient's favorable anatomy and no evidence of neurologic deficits or signs of distal malperfusion...

BACKGROUND: Tandem occlusions of the internal carotid artery (ICA) and middle cerebral artery (MCA) occur in up to a third of patients with acute ischemic strokes undergoing endovascular mechanical thrombectomy. Understanding open neurosurgical management of associated complications with this procedure is important. CASE REPORT: A 67-year-old man with acute onset of left hemiparesis and a tandem right ICA and MCA occlusion. He underwent carotid stent angioplasty of a stenotic ICA, followed by attempted Solitaire stent retrieval of an MCA clot...

Background Emergency stent placement in the extracranial internal carotid artery in combination with anterior circulation thrombectomy is a routine procedure. Yet, precise indications and clinical safety in this setting remains controversial. Present data for mechanical thrombectomy include few studies with acute stenting of tandem occlusions. We evaluated the feasibility, safety and clinical outcome of this endovascular treatment in a retrospective analysis of all consecutive cases at a comprehensive stroke centre...

The horizontal stenting technique facilitates endovascular treatment of wide-necked bifurcation intracranial aneurysms. Previous literature shows, however, that subsequent coil embolization at initial treatment results in incomplete obliteration in many cases. The authors present two consecutive cases of wide-necked large bifurcation aneurysms to describe an additional coil embolization technique following horizontal stenting. The patients were a 53-year-old female with an unruptured internal carotid artery terminus aneurysm and a 57-year-old female with a recurrent basilar artery tip aneurysm...

OBJECTIVE Treatment of wide-necked intracranial aneurysms is associated with higher recanalization and complication rates; however, the most commonly used methods are not specifically designed to work in bifurcation lesions. To address these issues, the authors describe the evolution in the design and use of the eCLIPs (Endovascular Clip System) device, a novel hybrid stent-like assist device with flow diverter properties that was first described in 2008. METHODS A registry was established covering 13 international centers at which patients were treated with the second-generation eCLIPs device...

CONDENSED ABSTRACT: The factors that impact the clinical effectiveness of bare nitinol stents in claudicants with symptomatic femoropopliteal atherosclerosis are incompletely known. The authors analyzed variables that may influence stent durability and provide a benchmark for their effectiveness. Data analyzed from six studies (999 patients) included baseline noninvasive hemodynamic tests, angiographic characteristics, ultrasound defined stent patency and target lesion revascularization through 12-months...

Purpose To evaluate glass-fiber-based guidewires that are safe for magnetic resonance (MR) imaging-guided endovascular interventions by using a phantom and an in vivo swine model. Materials and Methods MR imaging-safe guidewires were made from micropultruded glass and/or aramid fibers and epoxy resin with diameters of 0.89 mm (0.035 inch) for standard and stiff guidewires and 0.36 mm (0.014 inch) for micro guidewires. MR imaging visibility and mechanical properties were assessed in a pulsatile flow model. After approval was obtained from the institutional animal care and use committee, MR imaging guidewires were evaluated for standard endovascular procedures in nine pigs...

OBJECTIVE: Acute occlusions of the extracranial internal carotid artery (ICA) and a major intracranial artery respond poorly to intravenous tissue plasminogen activator (tPA) and present an endovascular challenge. The aim of our study was to retrospectively delineate the feasibility of the combined use of emergent carotid stenting and intra-arterial (IA) Abciximab with intracranial revascularization in the setting of acute ischemic stroke and carotid occlusions at our institution. METHODS: Eleven patients with complete cervical carotid occlusion with or without concomitant intracranial ICA and/or MCA occlusion were identified from a single center, retrospective review of patients admitted to the Stroke unit...

Vascular access maintenance is vital for hemodialysis patients. Conventional balloon angioplasty is the gold standard of treatment in endovascular therapy according to published guidelines, accompanied by bare metal stents as a bail-out method. Several devices have been used so far with a view to improve patency outcomes, but only covered stents have been proposed as a valid alternative and only for venous juxta-anastomotic stenosis of arteriovenous grafts. Paclitaxel-coated balloons (PCBs) have been extensively investigated in the last few years in pilot studies with small numbers of patients in dialysis access...

Swing-segment lesions are a fairly common reason for access failure and predispose to repeated interventions. The pathophysiology, hemodynamic circumstances and the primary intervention might all play a role in early recurrence. Mainly, percutaneous transluminal angioplasty (PTA), bare metal stenting and stent graft implantation have been performed to prolong lesion patency and access circuit patency. The available data on endovascular treatment of swing-segment lesions are scarce, heterogeneous and of poor quality...

INTRODUCTION: Most of the patients with iliofemoral thrombosis treated with anticoagulants only are affected with postthrombotic syndrome (PTS) that worsens the patients' quality of life. In the acute phase of proximal deep venous thrombosis (DVT) catheter-directed (CDT) and pharmacomechanical thrombolysis may be a reasonable alternative therapeutic method. Our aim was to summarize our results using these methods. METHODS: Since 2009 twenty-four patients with iliofemoral DVT were treated with these endovascular procedures and with stenting at our Institution...

INTRODUCTION: The Endologix developed an aortoiliac stent graft system that is different than the conventional implantation technique (Nellix, EVAS-endovascular aneurysm sealing system). The first implantation in Hungary has been performed in the beginning of 2016 at Heart and Vascular Center. METHODS: Nellix: two endobags surrounding ballon-expandable covered stent (10 mm) with optional length, biocompatible polymer which is able to be injected into the endobags and a procedure-coordinating console...

Carotid-internal jugular venous fistula is one of the rarest presentations among victims of bomb blast injuries. Treatment of such fistula is open surgery with high mortality and morbidity. Endovascular treatment with covered stent seems to have an optimal result with low complications. We present a case report of a bomb blast victim having carotid-jugular venous fistula with hemodynamic compromise. The patient was successfully managed with endovascular graft stent. There was an optimal result with no immediate and long-term complications...

Large celiac artery aneurysms are associated with a high rupture and mortality risk. Traditionally, open surgical repair has been the mainstay of treatment. Endovascular alternatives have been increasingly described, ranging from coil embolization to exclusion with covered stent grafts. However, certain features such as a short wide neck, small vessel diameters, and significant vessel tortuosity can limit these two options. We describe a 75-year-old man with a splenic and celiac trunk aneurysm that was treated using a combination of coil embolization to occlude the outflow artery and aneurysm sac, and an aortic stent graft cuff to block the inflow...

OBJECTIVE/BACKGROUND: Fenestrated endovascular repair (FEVAR) has been used to treat complex abdominal aortic aneurysms (AAAs). The risk of renal function deterioration compared with infrarenal endovascular aortic repair (EVAR) has not been determined. METHODS: Patients with preserved renal function (estimated glomerular filtration rate [eGFR] > 45 mL/minute) enrolled in two prospective, non-randomised studies evaluating Zenith fenestrated and AAA stent grafts were matched (1:2) by propensity scores for age, sex, hypertension, diabetes, and pre-operative eGFR...

BACKGROUND: Endovascular aneurysm repair (EVAR) with a modular endograft has become the preferred treatment for abdominal aortic aneurysms. A novel concept is endovascular aneurysm sealing (EVAS), consisting of dual endoframes surrounded by polymer-filled endobags. This dual-lumen configuration is different from a bifurcation with a tapered trajectory of the flow lumen into the two limbs and may induce unfavorable flow conditions. These include low and oscillatory wall shear stress (WSS), linked to atherosclerosis, and high shear rates that may result in thrombosis...
