Acute aortic dissection is the commonest life-threatening event involving the aorta. The diagnosis should always be considered when presented with a hypertensive patient with severe chest pain. Modern imaging modalities with rapid access to cross-sectional techniques have increased the frequency of diagnosis of type B dissection. This chapter describes the optimal management of acute type B dissection, from diagnosis, through primary medical management, planning surgical intervention, optimal anaesthesia and monitoring, to the final decision to offer surgical treatment. The mainstay of treatment for type B dissection is currently strict blood pressure control. However, when the dissection becomes complicated or the patient develops signs of impending rupture, surgical or endovascular intervention may be required.
