[Aortic dissection: role of the general surgeon in diagnostic-therapeutic procedure].
Aortic dissection occurs when there is a tear or separation of the aortic intima from the media; flow of blood into the intima-media space allows the tear to develop into a dissecting hematoma. Aortic dissection is a rare condition which represents an acute cardiovascular emergency for which the appropriate therapy is immediate surgical correction. Patients with aortic dissection show a heterogeneous constellation of symptoms; hence, clinical suspicion is often difficult. Only a minority of patients has "classic" symptomatology, the electrocardiogram is often misleading and the chest radiogram is almost always non-specific. In Italy, the usual "hospital routine practice" assigns the key-role in the emergency diagnostic procedure for these patients to the general surgeon. In view of the necessity of immediate cardiac surgery and the overwhelming likelihood of adverse events when surgery is delayed, techniques for diagnosis must be accurate, widely available and easily and quickly used. The present study consists of four case-reports of aortic dissection thoroughly examined and confronted with the literature. Management strategy based on emergency echocardiography is a reliable, feasible and successful technique for evaluating patients with aortic dissection. It allows a rapid accurate diagnosis with a single examination that can also be performed in the emergency room and provides information of sufficient diagnostic value to allow immediate cardiovascular surgery. CT scan and/or MRI are also valid tools for the emergency diagnosis of aortic dissection. However, a major problem still exists: the range of symptoms is sufficiently broad that a high index of "personal suspicion" of aortic dissection is required on the part of the general surgeon when he performs the role of "emergency-team leader".
