The Anaconda One-LokTM stent graft for the treatment of infrarenal abdominal aortic aneurysms: clinical results, technical, and mechanical characteristics.

Abstract

Introduction: The Anaconda aortic stent graft is a trimodular endovascular stent graft with an active infrarenal fixation suitable for the treatment of infrarenal abdominal aortic aneurysms with an infrarenal neck angulation ≤90°. A unique magnet-based mechanism facilitates the cannulation of the contralateral leg.

Areas covered: The present article provides a complete description of the third-generation Anaconda endograft, the Anaconda One-Lok^TM, its clinical performance and the related technical and mechanical characteristics as well as a brief comparison between itself and other similar endografts.

Expert opinion: The Anaconda One-Lok stent graft is particularly suitable for abdominal aortic aneurysms with an infrarenal aortic neck angulation up to 90°. Issues that need to be resolved concern the higher incidence of iliac limb occlusion and distal migration compared to other commercially available endografts and possibly the valley central migration with the risk of covering the renal ostia.
