The two major approaches to embolic protection (a distal filter device to “catch” emboli during the CAS, or, 2) a proximal occlusion device whereby antegrade flow in the vessel is stopped by occluding the CCA, and the potential emboli are aspirated prior to restoring antegrade flow in the carotid) are evaluated in a randomized, open-label trial of 60 adults at a single center with severe asymptomatic (>80%) or severe symptomatic (>50%) carotid stenosis who underwent CAS between July 2008-July 2011. Only one stent type was used.

Comparison of ultrasound guidance with the traditional palpation and fluoroscopy method for the common femoral artery puncture.

Ultrasound guidance for vascular access has become to standard of care for placement of central venous catheters, but femoral arteriotomies continue to be performed using only palpation and fluoroscopically-guided identification of the femoral head. Presumably, by precisely defining common femoral artery anatomy and thereby avoiding punctures above the inguinal ligament or punctures of the superficial femoral artery, ultrasound guided arteriotomy might decrease access site complications.

New endovascular technologies, such as the use of retrievable stents for thrombectomy and mechanical restoration of vessel patency (i.e., “stentrievers”) may have significant impact on clinical outcomes of patients with acute ischemic stroke, especially for strokes caused by occlusion of large intracranial vessels (2,3). The Mechanical Recanalization With Flow Restoration in Acute Ischemic Stroke (ReFlow) Study used a new stentriever revascularization device, the Solitaire FR (ev3, Irvine, California), to determine its safety and feasibility.

Management strategies for type B aortic dissection have evolved with the greater availability of newer technologies such as thoracic endovascular repair (TEVAR). This document offers recommendations based on review of current literature on the prognoses and management of acute, subacute, and chronic type B aortic dissection.

The optimal management of patients with cryptogenic stroke and a patent foramen ovale (PFO) is not known. While the association between presumptive paradoxical embolism across a PFO and cryptogenic stroke dates to the 19th century, there has not been any definitive trial evidence that mechanical closure of PFOs prevents recurrent events in patients with cryptogenic stroke.

This study demonstrates that patients who have undergone revascularization of femoropopliteal ISR are likely to benefit from a paclitaxel-eluting nitinol stent.
Endovascular treatment for infrainguinal vessels in patients with critical limb ischemia: OLIVE Registry, a prospective, multicenter study in Japan with 12-month follow-up
March 12, 2013 · No Comments
Critical limb ischemia (CLI) is an increasingly prevalent condition associated with substantial morbidity and mortality. Though endovascular therapy (EVT) is often used as a first-line revascularization therapy for CLI patients, prospective data reporting outcomes in contemporary practice are needed.

Given the superior outcomes of primary PCI over thrombolysis in ST-elevation myocardial infarction, it is conceptually attractive to assume that in acute ischemic stroke, endovascular therapy, with recanalization rates superior to systemic thrombolyisis, would be superior to IV TPA . Ciccone, et al. challenge this premise with their provocative study that shows no difference in disability-free survival at 90 days.
Effect of Ramipril on Walking Times and Quality of Life Among Patients With Peripheral Artery Disease and Intermittent Claudication: A Randomized Control Trial
February 25, 2013 · No Comments
Current drug treatments only provide modest improvement in the walk distance for patients with peripheral artery disease (PAD) and intermittent claudication. Results from previous trials investigating ramipril therapy in improving walk distance in claudicants have been mixed. This randomized trial conducted by Ahimastos and colleagues demonstrate that ramipril therapy may lead to notable improvements in walking ability in patients with PAD.
