Usefulness of Corsair Armet: penetration force and shaft rigidity

Takashi Shimonaga

Patient was an 81-year-old male. He had been diagnosed as ASO and treated to the bilateral superficial femoral artery (SFA), and had been repeated the in-stent occlusion. He admitted to our hospital complaining resting pain of the right leg. As a result of the contrast examination, in-stent occlusion of the right SFA and stenosis of the left external iliac artery (EIA) were observed, so we performed endovascular therapy (EVT).

In our strategy, we used Corsair Armet effectively which is a micro catheter with high penetration force and shaft rigidity.

At first, EVT to right SFA was performed with cross over approach using 6Fr Destination inserted from left common femoral artery (CFA). To pass the in-stent occlusion lesion, we pushed only the tip of Corsair Armet from lesion entry site to just above exit site like IVUS knuckle technique. Because of its high penetration force, we could pass the in-stent occlusion lesion easily. Next we penetrated just in-stent occlusion exit point with 0.014 inch wire and performed aspiration and balloon dilatation.

Subsequently, EVT to left EIA was performed. The lesion was simple stenosis, so we performed balloon dilatation and stent placement after confirming the vessel diameter with IVUS. In this case, instead of 0.035 inch wire, we used Corsair Armet placed on 0.014 inch wire as strong shaft for stent delivery. We could deliver the stent easily and subsequently observe the IVUS without exchanging the wire.

We report a case that Corsair Armet could be used effectively.
