Acute type B aortic dissection is a life threatening disease process, which remains a clinical dilemma despite advances in technology, surgical technique and postoperative management. The variability of presenting symptoms, lack of a consensus on indications for treatment and differing opinions about the optimal timing for repair have added to the management confusion. Medical management has been the standard of care for acute uncomplicated type B dissection. ⋯ Recent data suggest that early TEVAR lowers aortic-related events and improves long-term aortic specific survival by covering the entry tear, promoting false lumen thrombosis and inducing aortic wall remodeling. The paucity of supporting data has created controversy surrounding the optimal treatment strategy for acute type B dissection. Nonetheless, recent healthcare trends show a paradigm shift towards the utilization of early TEVAR in acute type B dissection.

Spinal cord ischemia (SCI) after thoracic and thoracoabdominal aortic aneurysm repair is a devastating complication, which happens after both open and endovascular repair. Incidence of SCI varies widely in the literature. Many factors during preoperative, operative and postoperative phases influence this incidence. The purpose of this article was to provide an overview on all factors influencing SCI and to report on the evidence in the literature about how to prevent SCI.
