[Neurological signs in aortic dissection].

A substantial number of patients suffering from aortic dissection will show neurological signs. These can dominate the clinical picture and hinder an accurate diagnosis of this life-threatening disease. We present a case of lower extremity pain and a case of transient global amnesia caused by aortic dissection. A third patient suffered from acute cerebral ischemia accompanied by hypotension and back pain, suggestive of aortic dissection. In this third case, aortic dissection was excluded before systemic thrombolytic therapy was administered, for the patient could have suffered disastrous complications caused by this emergency stroke therapy. Clinicians should be aware that a wide range of cerebral, spinal and peripheral neurological signs can be caused by aortic dissection. An unusual combination of symptoms can be a clue for underlying aortic disease. High-risk clinical features are predisposing factors in medical history, typical acute onset back or chest pain, and pulse deficit, blood pressure asymmetry or a new cardiac murmur on physical examination. These features should be explicitly evaluated in patients with an acute neurological deficit. If neurological symptoms and a high-risk clinical feature are present, immediate aortic imaging should be considered since early detection can be life saving.
