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.

Subtotal tongue necrosis in delayed diagnosed giant-cell arteritis: a case report.

Giant-cell arteritis (GCA) is a chronic systemic vasculitis of large- and medium-sized vessels, mainly affecting elderly patients. Headache, vision impairment, jaw claudication, and scalp tenderness are common symptoms. However, diagnosis can be difficult because GCA can affect almost every vascular pathway and lead to a variety of possible manifestations. We report the case of a belated diagnosed GCA, resulting in nearly complete necrosis of the mobile part of the tongue, visual impairment, and neurologic as well as intestinal ischemic symptoms. Aggressive immunosuppressive treatment resolved the symptoms, but the patient remained severely morbid because of bilateral necrosis of the mobile part of the tongue. In any case of unclear ischemic symptoms in an elderly patient, one must keep GCA in mind as the possible culprit disease.
