Abstract
We describe the use of a carotid filter in preventing distal emboli during the recanalization of an occluded left iliac stent two months earlier. The filter was reversed and introduced through an ipsilateral 6 French sheath along its 0.014“ guidewire and placed against the occluded stent. The stent is recanalized using a hydrophilic guidewire controlaterally and a new stent was inserted into the old one. The filter was retracted into the introducer by pulling cut the special 0.014 guidewire, with a 0.018” diameter tip, and the whole system was removed via the left common femoral artery. Many emboli were found in the removed filter. We noted that the recanalization of an occluded stent causes more distal embolization than the native iliac artery. This technique allows placing the filter between the embolic lesion and the distal arterial territory, without passing through the lesion, especially since fibrinolysis may not be efficient in 2-months-old occlusions.
