Stenting for external outflow graft obstruction of a left ventricular assist device via a surgical axillary approach.
External outflow graft obstruction is an uncommon late complication in patients supported with a fully magnetically levitated left ventricular assist device. Progressive extrinsic compression of the outflow graft can impair pump performance and lead to symptomatic deterioration, requiring intervention to restore graft patency. This video tutorial presents a hybrid procedure combining surgical transaxillary access with endovascular stent implantation for treatment of external outflow graft obstruction when transfemoral access is not feasible. A 72-year-old woman with ventricular assist device support presented with exertional dyspnoea. Imaging demonstrated a persistent external narrowing of the outflow graft distal to the cannula, and invasive assessment confirmed a significant pressure gradient. Severe kinking of the femoral vessels excluded conventional femoral access. After induction of general anaesthesia, the axillary artery was exposed through an infraclavicular incision and accessed under direct vision. A vascular sheath was introduced, allowing retrograde advancement of guidewires across the stenotic graft segment. Two overlapping balloon-expandable covered stents were deployed under fluoroscopic guidance to restore luminal diameter and antegrade flow. Completion angiography confirmed satisfactory stent expansion and improved device flow.
期刊介绍:
The Multimedia Manual of Cardio-Thoracic Surgery (MMCTS) is produced by The European Association for Cardio-Thoracic Surgery (EACTS). MMCTS is the world’s premier video-based educational resource for cardiovascular and thoracic surgeons; freely accessible - and essential - for all. MMCTS was launched more than ten years ago under the leadership of founding editor Professor Marko Turina. It was Professor Turina’s vision that the European Association for Cardio-Thoracic Surgery (EACTS), already the world-leader in CT surgery education, should take advantage of the Internet’s rapidly improving video publication capabilities and create a new step-by-step manual of surgical procedures. Professor Turina and EACTS agreed that the manual, MMCTS, should be freely accessible to all users, regardless of association membership status, nationality, or affiliation. MMCTS was self-published by EACTS for some years before being transferred to Oxford University Press, which hosted it until the end of 2016. In November 2016, the Manual returned home to EACTS and it has now relaunched in a completely new format. Since its birth in 2005, MMCTS has published some 400 detailed, video-based demonstrations of cardio-thoracic surgical procedures. Tutorials published prior to 2012 have been archived and we are working with the authors of these tutorials to update their work pending republication on the new site. Our mission is to make MMCTS the best online reference for cardio-thoracic surgeons – residents and experienced surgeons alike. Our aim is to include tutorials presenting procedures at both a fundamental and an advanced level. Truly innovative procedures are also included and are identified as such.
