Event Description
|
Physician used a silverhawk device during treatment of a 200 mm calcified lesion in the patient¿s mid, distal and proximal right superficial femoral artery (sfa) of diameter 6 mm.Moderate tortuosity and calcification are reported.Lesion exhibited 30-40% stenosis.Ifu was followed.Device prepped without issue.It is reported that the device was used without issue to treat an initial cto at mid/distal lesion.Four passes were made with the silverhawk device.Minimal resistance was experienced when removing the device.Minimal grip applied and the resistance was relinquished as break occurred.Angiogram visualized a loop in the wire distal to sheath tip and confirmation of device tip remaining on wire.A dilator advanced through the sheath in an attempt to straighten wire unsuccessfully, resulting in the wire breaking apart.The dilator and wire end were removed.A non-medtronic 0.014 guidewire was advanced to the original lesion, followed by successful use of two nanocross pta balloons at 10atm and 8 atm respectively.A gooseneck snare was then advanced via right antegrade access with a 6fr sheath in attempt to snare the broken wire and tip.Multiple unsuccessful attempts were made with the goosneck snare.The physician ultimately decided to stent the broken wire and silverhawk tip against vessel wall.
