BACKGROUND AND PURPOSE: For patients with acute ischaemic stroke due to large-vessel occlusion, it has recently been shown that mechanical thrombectomy (MT) with stent retrievers is better than medical treatment alone. However, few hospitals can provide MT 24 h/day 365 days/year, and it remains unclear whether selected patients with acute stroke should be directly transferred to the nearest MT-providing hospital to prevent treatment delays. Clinical scales such as Rapid Arterial Occlusion Evaluation (RACE) have been developed to predict large-vessel occlusion at a pre-hospital level, but their predictive value for MT is low...

Superior vena cava syndrome is a well-known disease entity that carries substantial rates of morbidity and mortality. Although most cases of superior vena cava syndrome are secondary to a malignant process, additional causes (such as mediastinal fibrosis, pacemaker lead implantation, or central venous catheter placement) have been reported. Multiple treatment options include percutaneous transluminal angioplasty, stent implantation, thrombolysis, mechanical thrombectomy, and venous grafting. We present a case of superior vena cava syndrome in a symptomatic 30-year-old woman who obtained complete relief of obstruction and marked symptomatic improvement through venoplasty and stenting, aided by our use of a balloon-in-balloon catheter system...

OBJECTIVE: It is difficult to decide whether to treat unruptured intracranial aneurysm(UIA)in elderly patients aged ≥80 years because they have potentially shorter life expectancy and risks related to treatment. Here, we report the results of the treatment of patients aged ≥80 years. METHODS: A retrospective review was performed in patients who underwent surgical or endovascular treatment between April 2012 and December 2015 at our institution. RESULTS: Between April 2012 and December 2015 we treated 130 UIA patients who presented with 145 aneurysms and 12 patients who presented with 14 aneurysms, who were aged ≥80 years...

HIV and tuberculosis infections are known to be associated with vasculopathy including occlusive disease and aneurysm formation. We report a case of 43-year-old male with miliary and central nervous system (CNS) tuberculosis; recently, diagnosed as HIV seropositive, on antiretroviral and antitubercular treatment presenting with painful neck swelling. He was found to have common carotid artery (CCA) pseudoaneurysm that was managed by endovascular stent grafting. HIV vasculopathy-related CCA pseudoaneurysm is a potentially life-threatening rare entity...

Endovascular and surgical techniques are conventional options for treating intracranial aneurysms, but criteria for selecting an optimal approach for individual patients remain variable across practitioners and institutions. While endovascular and surgical approaches are generally used alone, both modalities combined in single patients can produce efficacious outcomes. The aim of this study was to evaluate outcomes of combined, concomitant endovascular and surgical modalities in the treatment of multiple and/or complex aneurysms in single patients...

BACKGROUND: Ruptured intracranial fusiform aneurysms involving small-diameter parent arteries are difficult to treat. Parent artery occlusion is a relatively simple and reliable treatment. However, occasionally, the parent arteries have to be retained. The arrival of the low-profile stent (LVIS(TM) Jr.) has made reconstructive endovascular treatment for fusiform aneurysms involving small-diameter parent arteries possible. CASE DESCRIPTION: This report describes an innovative method for stent-assisted coiling (stenting after coiling technique using only one microcatheter), and describes our initial experience and feasibility of this technique...

BACKGROUND: Endovascular therapy (EVT) with stent retrievers in addition to i.v. thrombolysis (IVT) has proven effective in acute stroke patients with middle cerebral artery (MCA, M1 segment) and distal internal carotid artery (ICA) occlusion. Limited data exist concerning acute cervical ICA occlusion, either alone or in combination with intracranial ICA occlusion (tandem occlusion). Therefore we analyzed outcome and treatment effects in stroke associated with cervical ICA occlusion, with specific focus on the impact of intracranial ICA or M1 patency...

PURPOSE: To compare the efficacy of an embolization agent with sclerosing properties (made of chitosan and sodium tetradecyl sulfate, CH-STS) with a similar embolization agent but without sclerosing properties (made of chitosan, CH) in treating endoleaks in a canine endovascular aneurysm repair model. METHODS: Two chitosan-based radiopaque hydrogels were prepared, one with STS and one without STS. Their rheological, injectability, and embolizing properties were assessed in vitro; afterwards, their efficacy in occluding endoleaks was compared in a canine bilateral aneurysm model reproducing type I endoleaks (n = 9 each)...

Hepatocellular carcinoma (HCC) patients with main portal vein tumor thrombus have a median survival time of only about 4 months. We therefore compared the safety and efficacy of endovascular brachytherapy (EVBT) and sequential three-dimensional conformal radiotherapy (3-DCRT). From a cohort of 176 patients, we treated 123 with EVBT using iodine-125 seed strands (group A) and the remaining 53 with sequential 3-DCRT (group B). Overall survival, progression free survival and stent patency characteristics were compared between the two groups...

OBJECTIVE: Endovascular aneurysm repair (EVAR) has progressively expanded to treat more challenging anatomies. Although EVAR in patients with wide infrarenal necks has been reported with acceptable results, there is still controversy regarding the longer-term outcomes. Our aim is to determine the impact of infrarenal neck diameter on midterm outcome following EVAR with a single endograft with suprarenal fixation. METHODS: A retrospective case-control study was designed using data from a prospective multicenter database...
