  • Title: [Acute aortic dissection. Differential diagnosis of a thoracic emergency].
    Author: Grundmann U, Lausberg H, Schäfers HJ.

    Abstract:
    Acute aortic dissection is an infrequent but important differential diagnosis of acute chest pain. The variability of presenting symptoms makes it difficult to diagnose correctly. Important clinical indicators - besides chest pain - are symptoms related to acute aortic insufficiency and/or pericardial tamponade, variable acute neurologic alterations, or signs of peripheral or visceral malperfusion. The spontaneous prognosis depends on the location and extent of the dissection, and left untreated dissection carries a high mortality. The key goal of preclinical treatment is stabilization with analgesia, mild sedation (opioids, benzodiazepines) and treatment of hypertension (beta-blockers) or hypotension (fluid administration). If the patient presents with a high probability of dissection, early transfer to a specialized center appears advisable. Initial clinical diagnostic studies include transthoracic echocardiogram and computed tomography. If the ascending aorta is involved (Stanford type A) immediate replacement of the proximal aorta is necessary. Isolated dissections of the descending aorta (type B) require aggressive blood pressure control, but can be managed conservatively in most cases. A high level of vigilance is necessary in all patients to detect and treat visceral ischemia.
