Randomized Controlled Trial Comparative Study
Paclitaxel-coated balloon angioplasty vs. plain balloon dilation for the treatment of failing dialysis access: 6-month interim results from a prospective randomized controlled trial.
To report the 6-month results of a prospective randomized trial investigating angioplasty with paclitaxel-coated balloons (PCB) vs. plain balloon angioplasty (BA) for the treatment of failing native arteriovenous fistulae (AVF) or prosthetic arteriovenous grafts (AVG). ⋯ PCB angioplasty improves patency after angioplasty of venous stenoses of failing vascular access used for dialysis.

Multicenter Study
Valiant thoracic stent-graft deployed with the new captivia delivery system: procedural and 30-day results of the Valiant Captivia registry.
To evaluate procedural and 30-day outcomes of thoracic endovascular aortic repair (TEVAR) employing the Valiant Thoracic Stent Graft with the Captivia Delivery System. ⋯ In this analysis of procedural and 30-day results, the high technical success and clinical outcome rates showed that the Valiant Thoracic Stent Graft with the new Captivia Delivery System has promising capacity to treat a variety of thoracic aortic conditions in a range of anatomies.

To investigate the feasibility and safety of vascular closure device (VCD) deployment outside the catheterization laboratory. ⋯ VCD deployment outside the catheterization laboratory does not increase the rate of major vascular complications and may be an alternative approach for femoral artery hemostasis when VCD deployment needs to be deferred.

Comparative Study
A comparative analysis of bench-top performance assessment of distal protection filters in transient flow conditions.
To compare the performance in vitro of 6 distal protection filters (DPFs) on the basis of filtration ability and effects on pressure gradient and vascular impedance in a flow model of the internal carotid artery (ICA). ⋯ A bench-top flow apparatus exhibiting physiologically realistic conditions was developed by combining pulsatile flow and a body temperature blood analog. Using microspheres larger than the pore size of most of the DPFs, the device-wall apposition has an important effect on the overall filter performance and the global fluid dynamics in the flow model.

Comparative Study
Type II endoleaks after endovascular repair of abdominal aortic aneurysms: fate of the aneurysm sac and neck changes during long-term follow-up.
To evaluate the frequency of type II endoleaks after endovascular aneurysm repair (EVAR) and to compare sac diameter and neck changes in patients with type II endoleak to endoleak-free patients with at least 3-year imaging follow-up. ⋯ Persistent type II endoleaks led to significant aneurysm sac enlargement, but without increased mortality or rupture rates.
