PAST, a novel solution for crossing another wire in the severely dissected peripheral artery

The most prevalent symptom of lower limb artery occlusions is intermittent claudication. The most commonly used technique to treat symptomatic patients is balloon dilatation of the occlusive plaque. Balloon dilatation of the lesion may cause dissection. The dissected artery wiring is a challenging scene. First, we can implant a stent in the dissection and then use it to cross the sealed artery. Additionally, we can use dual lumen catheters or dual lumen balloon catheters. But sometimes, angiography labs do not have these modern devices. In the present case, we came up with a solution and successfully finished the procedure by using a balloon catheter to transfer the second guidewire, which cannot pass through the dissected lesion. We named the technique Peripheral Artery Sidecar Technique (PAST).
