Application of the VORTEC Technique in Creating a Proximal Inflow Conduit in the Circumferentially-Calcified or "Lead-Pipe" Aorta.

A heavily calcified or "lead-pipe" aorta can present many challenges to any surgeon. There is higher risk of vessel wall rupture or disruption, distal embolization, and prolonged ischemia time of visceral organs due to longer clamp times. Hybrid revascularization techniques, which were originally described in visceral revascularization during complex aortic procedures, can be potentially utilized for lower extremity bypasses. These techniques, such as "VORTEC," are well-studied and have been shown to have similar patency rates as traditional bypass grafts with the added benefit of decreased ischemia time and lower levels of acute kidney injury and visceral organ ischemia. This allows VORTEC and other similar hybrid techniques to be utilized as options when traditional vessel control cannot be safely achieved during distal revascularization procedures, as we describe in our patient.
