Experience with inner branch off the shelf device for thoracoabdominal aneurysms

Endovascular treatment of complex aortic aneurysms (cAAA) including thoracoabdominal aortic aneurysms is becoming more common. Most patients require custom made devices and until recently the off the shelf (OTS) options were limited. The aim of this manuscript was to describe a new inner branch OTS device and its clinical applications. A review of the current literature on the ENSIDE device from Artivion was performed and the authors' experience presented. The short outcomes of this particular OTS device are acceptable and the anatomical suitability on par with other similar devices. The preloaded configuration of the device can offer benefits in complex anatomy. New OTS devices for cAAA can provide treatment in emergent or urgent situations in many patients. Long term follow-up is needed and caution must be made against excessive use in less extensive aneurysms due to the risk of spinal cord ischemia.
