Peripheral ischemia caused by paradoxical embolization: an underestimated problem?
Although a patent foramen ovale (PFO) is often found in younger patients with transient ischemic attacks or stroke, paradoxical embolization through PFO is rarely considered as a cause of acute limb ischemia. We report a single-center experience of 5 consecutive patients with limb-threatening ischemia due to paradoxical embolization within a one-year period. All patients were treated by catheter thrombectomy and long-term oral anticoagulation after surgery. The fact that the 5 embolectomies made up 10% of all embolectomies performed in our center during this time interval may indicate that the role of paradoxical embolization is still underestimated in peripheral embolic disease.
