RESUMO
Leriche syndrome was diagnosed in three patients aged 63, 71 and 73. They presented with a wide range of neurological symptoms such as impotence, pain or dysfunction of the lower extremities. Because a neurological diagnosis was initially suspected, there was a delay in two of the three patients before palpation for a distal pulse in the lower extremities was performed. A pulse was absent in all three patients. Duplex sonography, MR angiography and CT angiography revealed that a pulse was absent due to aortoiliac occlusive disease, also known as Leriche syndrome. They underwent treatment with covered endovascular reconstruction of the aortic bifurcation (CERAB), aortobifemoral bypass or intravenous thrombolysis. All patients significantly improved after treatment. Physicians should always consider aortoiliac occlusive disease in patients who present with neurological symptoms of the lower extremities and must check for a distal pulse in these patients.
