Here one can see hemodynamically significant stenosis at the origin of the left anterior tibial artery.

This control angiogram was taken following CryoPlasty therapy with a 3.0 mm balloon.

As one can see here, the stenosis of the left dorsalis pedis artery crosses the ankle joint.

Surgeons used a 2.5 mm diameter CryoBalloon across the dorsalis pedis artery stenosis.

Here is a control angiogram of the dorsalis pedis artery following 2.5 mm CryoPlasty therapy. As one can see, there is significant improvement in the caliber of the artery with a focal area of vasospasm several millimeters below the ankle joint.

After the patient underwent transmetatarsal amputation, the left foot showed exuberant bleeding. This signifies good blood flow to the wound site.

This case study demonstrates the suitability of delivering the small vessel cryoballoon to a distal lesion below the ankle. The patient underwent angioplasty without the creation of a prominent dissection across a 30 mm length occluded segment and two additional sites. There was vigorous bleeding during surgery, a favorable prognostic sign, and the surgical wound was healing at three weeks.

While the primary objective in this case is limb salvage and wound healing, further follow up in a controlled environment will be necessary before one can make statements regarding patency rates.
