The pruitt occlusion catheter (poc) and xenosure were used in one case of endarterectomy + evt.After endarterectomy of the right femoral artery and placement of a metal stent, the shaft of the poc was inserted into the vessel to place a patch at the endarterectomy site.However, the balloon of the poc ruptured, so the blood flow could not be blocked.Since the stent was placed on the proximal side of the endarterectomy site, it was not possible to occlude the blood vessel using vascular clamp.So, pta balloon was used instead to occlude the blood flow.The xenosure patch was sutured to the endarterectomy site and the surgery was completed.The patient is doing well and there were no health complications.The cause of the balloon rupture appears to be contact with the metal part of the stent.
