It was reported that removal difficulties, balloon rupture, and shaft break occurred.
The patient underwent percutaneous transluminal angioplasty (pta) for graft occlusion after bypass from the superficial femoral artery to the popliteal.
The stenosed target lesion was located in the moderately tortuous and non calcified below the knee vessel.
A 4f introducer sheath was positioned.
After crossing the wire, the anterior tibial artery (ata) and posterior tibial artery (pta) were dilated with 2.
0 x 4 coyote balloon catheter.
A 4mm x 40mm x 146cm coyote es balloon catheter was then used to dilate the trunk section.
There was no resistance noted during balloon delivery.
The 4mm x 40mm x 146cm coyote es balloon catheter was deflated and there was resistance noted during removal of the balloon catheter from the lesion.
At that time, the 4mm x 40mm x 146cm coyote es balloon catheter ruptured and the shaft broke.
The introducer sheath was changed to 6f, and the separated 4mm x 40mm x 146cm coyote es balloon catheter was retrieved with a snare.
In retrieving the 4mm x 40mm x 146cm coyote es balloon catheter, the shaft was elongated and twisting was also observed.
The procedure was completed and no patient complications nor injuries were reported.
