- Cryoablation, which induces cellular death without extensive tissue damage, has been extensively used to denervate the myocardium. However, periadventitial external circumferential application of cryotherapy to denervate the renal artery sympathetic nerves has, to our knowledge, never been tested in humans. The main aim of this study was to examine the safety and potential effects of cryotherapy on ambulatory blood pressure levels and other outcomes that are indirectly related to sympathetic tone, including pulse-wave velocity, central pulse pressure, and glucose levels.

- Major branches of the aortic arch and visceral aorta pose a particular challenge for endovascular repair of aneurysms involving these regions. To preserve perfusion through these essential branches, fenestrated and branched endografts have been used. Current fenestrated and branched aortic endografts have evolved into modular devices in which the aortic main body provides appropriate access to the target branch vessel either through reinforced fenestrations or directional cuffs as the hinge point for bridging stent grafts (BSGs). BSGs are used to connect the aortic main body and target branch vessel, and must provide both unhindered flow and a seal. Appropriate selection of BSG for target vessels in branched and fenestrated endovascular aortic repair is critical for technical success and durability. At present, there are no dedicated devices for use as BSGs, and a variety of stent grafts are currently used off-label. In this report, we review the available published series on the performance of presently available BSGs in relation to their design and selection.
