Time to Reperfusion and Treatment Effect for Acute Ischemic Stroke: A Randomized Clinical Trial.

Importance: Intra-arterial treatment (IAT) for acute ischemic stroke caused by intracranial arterial occlusion leads to improved functional outcome in patients treated within 6 hours after onset. The influence of treatment delay on treatment effect is not yet known.

Objective: To evaluate the influence of time from stroke onset to the start of treatment and from stroke onset to reperfusion on the effect of IAT.

A randomized trial of intraarterial treatment for acute ischemic stroke.

Background: In patients with acute ischemic stroke caused by a proximal intracranial arterial occlusion, intraarterial treatment is highly effective for emergency revascularization. However, proof of a beneficial effect on functional outcome is lacking.

Methods: We randomly assigned eligible patients to either intraarterial treatment plus usual care or usual care alone.

Endovascular aneurysm sealing for juxtarenal aneurysm using the Nellix device and chimney covered stents.

Purpose: To show the feasibility of the Nellix device in conjunction with a chimney technique for treating juxtarenal aneurysms in two patients who were deemed unsuitable for fenestrated endovascular aneurysm repair or open surgery.

Case Reports: Two men aged 83 and 81 years were referred with a juxtarenal abdominal aortic aneurysm (66 and 69 mm, respectively). Both were considered for open surgery as well as custom-made fenestrated stent-graft but deemed unsuitable for both options.

Geometrical consequences of kissing stents and the Covered Endovascular Reconstruction of the Aortic Bifurcation configuration in an in vitro model for endovascular reconstruction of aortic bifurcation.

Objective: Kissing stents (KS) are commonly used to treat aortoiliac occlusive disease, but patency results are often lower than those of isolated stents. The Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB) technique was recently introduced to reconstruct the aortic bifurcation in a more anatomical and physiological fashion. The aim of this study is to compare the geometrical consequences of various stent configurations in vitro.

Endovascular versus surgical revascularization in proximal subclavian artery obstruction.

Background: The aim of this paper was to compare the outcomes of endovascular versus surgical treatment in patients with symptomatic proximal subclavian artery obstruction through a retrospective clinical study. Treatment of symptomatic subclavian artery obstruction can be performed with percutaneous transluminal angioplasty or open surgical reconstruction. Comparative studies are scarce.
