TriVascular Technologies, Inc. announced the commencement of enrollment in the LIFE Study, a multicenter postmarket registry designed to evaluate the Ovation Prime abdominal stent graft system in the treatment of patients with abdominal aortic aneurysms (AAA) using a fast-track protocol for endovascular aneurysm repair (EVAR).
Bolton Medical announced the initiation of the Regeneration clinical trial that will assess the safety and effectiveness of the company’s Relay Pro and Relay NBS Pro thoracic stent graft systems in patients with thoracic aortic pathologies. The study results will support the company´s application for CE Mark approval of the Relay Pro devices.
TriVascular announced that the US Food and Drug Administration has approved its CustomSeal technology for the Ovation Prime endograft system. The customized sealing technology enables faster procedure times, preserves the aortic neck, and provides an optimized seal that is tailored to each patient´s specific anatomy, stated the company.
Julie Brittenden, MD, et al published findings from a randomized trial comparing treatments for varicose veins in the New England Journal of Medicine (2014;371:1218–1227). The background of the study is that ultrasound-guided foam sclerotherapy and endovenous laser ablation are widely used alternatives to surgery for the treatment of varicose veins, but their comparative effectiveness and safety remain uncertain, noted the investigators. The study was sponsored by the University of Aberdeen in Scotland, United Kingdom.
The national principal investigator of the ATTRACT study shares his insights on DVT treatment, regulatory hindrances in the venous space, and the progression of interventional radiology fellowships.
Venous return is attained through a complex interaction of valves, muscle pumps, and pressure gradients and is greatly influenced by position. In the upright position, gravity is counteracted by the valve-pump system; however, in the supine position, hydrostatic pressure disappears, and pressure gradients effect flow. Duplex ultrasound (DUS) technology uses sound to provide relatively limited information about this complex physiologic system. The physician must therefore rely mostly on clinical skills when treating patients with venous disease.
Varicose veins are largely treated by changing the circulatory pattern created by the underlying valvular failure. This frequently involves disconnecting superficial and deep connections that have incompetent valves to stop the flow from high-pressure deep veins back into low-pressure superficial veins and then ablating the damaged superficial veins (varicosities) either surgically, chemically, or thermally. Because there are numerous connections from superficial to deep veins (perforators) that could potentially fail,1 recurrence should be less of a surprise than the lack thereof. Good treatment necessitates the identification of these abnormal connections, which requires imaging that both identifies the perforator and demonstrates the abnormal flow. The use of duplex ultrasound has greatly improved the accuracy of identifying the problematic perforator, the most common being the saphenofemoral junction.
Determining therapeutic protocol for acute and chronic DVT.
Clarification of questions arising about the use of a new code for venous embolization, 37241.
Michael R. Jaff, DO, discusses the differences between the arterial and venous stent landscapes and what the future might hold.
A study that examined the incidence of cerebral microembolization and silent cerebral infarction after thoracic endovascular aneurysm repair (TEVAR) concluded that two-thirds of patients undergoing MRI had evidence of silent cerebral infarction—a previously unrecognised burden.
Suresh Vedantham, professor of Radiology, Interventional Radiology Section, Washington University School of Medicine in St Louis, USA, spoke to Interventional News on the latest from the paper “Quality improvement guidelines for the treatment of lower-extremity deep vein thrombosis with use of endovascular thrombus removal” hot on the heels of its online publication in the Journal of Vascular and Interventional Radiology (JVIR).
Sapan Desai (Department of Vascular Surgery, Southern Illinois University, USA) and colleagues report in the Journal of Vascular Surgery that the ongoing decrease in open aneurysm repair that has occurred as a result of the increase in endovascular aortic aneurysm repair (EVAR) may mean that next-generation vascular surgeons do not gain sufficient experience in open repair during training and, therefore, may be ill prepared to perform the procedure.
Cardiatis announced plans of targeting Crawford Extent V lesions with its second generation aortic multilayer flow diversion device, the Cardiatis C5.
November 5, 2014—VIVA Physicians, Inc. announced that Peter A. Schneider, MD, presented findings from a subanalysis of a series of patients treated by urgent endovascular aneurysm repair (EVAR) using EndoAnchors (Aptus Endosystems, Inc.) in the larger ANCHOR global registry. Dr. Schneider presented the ANCHOR subset data during the late-breaking trials session at the VIVA 2014: Vascular InterVentional Advances meeting in Las Vegas, Nevada. There is critical need in urgent EVAR for a bailout adjunct to treat proximal seal complications or address concerns in complex proximal neck anatomy, noted the announcement.
