4. Retract and redirect wire
Figure 1. Guidewire in deep circumflex iliac artery
Correct Answer: Retract and redirect wire The lateral course of the guidewire suggests that is located in the deep circumfex iliac artery (Figure 2). Inserting a sheath over the guidewire into this small branch could result in perforation. Simple wire redirection was successful in advancing the guidewire into the right external iliac artery (Figure 3).

Option 1: Calling vascular surgery is not necessary unless a perforation is confirmed with contrast extravasation that cannot be controlled in the cath lab.
Option 2: Switching to radial access is possible, but will likely not be necessary if simple wire redirection achieves the goal of safely obtaining femoral arterial access.
Option 3: Covered stent deployment is also not required, since no perforation has occurred; moreover, stent implantation in the common femoral artery is suboptimal as it is prone to fracture.
