Researchers have published the report of a study comparing the outcomes of limbs with and without direct flow by angioplasty based on the angiosome concept in critical limb ischemia (CLI) in patients with isolated below-the-knee (BTK) lesions, as well as the rates of limb salvage associated with successful achievement of feeding artery flow by endovascular therapy. The analysis included 369 limbs from 329 patients and follow-up took place at an average of 18 months. The data indicated that achieving direct flow by angioplasty is “clinically important for amputation-free survival and freedom from major amputation and major adverse limb events.” (Journal of Vascular Surgery) February, 2012

A study published in the Annals of Vascular Surgery has indicated that patients undergoing a secondary procedure following abdominal aortic aneurysm have an improved survival rate compared to patients who did not receive the additional procedure. Researchers set out to evaluate the effects of secondary procedures by studying 162 patients, of which 39 underwent additional procedures to treat aneurysm related complications, and concluded that secondary procedures are associated with improved survival rates, but this may be “related to the fact that they (patients undergoing secondary procedures) were younger at the time of stentgraft implementation.” (Annals of Vascular Surgery) February, 2012

The American Heart Association (AHA) has published a statement in its journal, Circulation, encouraging researchers to undertake more population-based studies evaluating the gender-specific differences associated with peripheral arterial disease (PAD). The physicians supporting the emphasis cite the potential for discrepancies in the measurement of the ankle-brachial index as well as the potentially greater risk for women than men to develop PAD. The AHA’s writing committee concluding recommendations included improving “data collection for gender-specific outcomes” in clinical studies in order to examine the role of gender on vascular biology.

Aptus Endosystems, Inc. has initiated its ANCHOR postmarket registry, following 510(k) clearance from FDA for the HeliFX system, intended for use during endovascular aneurysm repair. The registry will be used to track the use of the company’s HeliFX aortic securement system for the treatment of abdominal aortic aneurysms. The device can be used alongside endografts manufactured by Cook Medical, Gore & Associates, and Medtronic, Inc. ANCHOR will collect data from several international centers in two phases, including enrolling up to 1,000 patients in each phase. Follow up will be conducted for up to five years.

AngioDynamics has received FDA 510(k) clearance for its NeverTouch Direct Procedure Kit used alongside the Company’s VenaCure EVLT Laser Vein Ablation System for the treatment of varicose veins and the incompetence and reflux of superficial veins of the lower extremity. The device functions without the need for a guide wire or guiding sheath and delivers “less pain and bruising compared to bare-tip fibers,” according to AngioDynamics.

The Millennium Research Group (MRG) has published its forecast for the European vascular access device market through 2016. The report predicts that the market will grow in the next 4 years attributed primarily to increased sales of “premium priced safety short peripheral intravenous catheters (PIVCs).” MRG estimates that the sale of safety short PIVCs will account for 81% of the total PIVC market revenue, up from 69% in 2011, driving overall revenue growth in vascular access sales.
