Figure 1 Entire cohort survival distribution function. This graph demonstrates that presentation with acute dissection with malperfusion and ischemic end-organ dysfunction is an important adverse risk factor for long-term survival. Mean survival times were higher in the uncomplicated group (UC 95.9 months vs MP 53.7 months; P < .001). Note that these curves are relatively parallel beyond the first 3 months, thus emphasizing the predominant early effects on survival in patients with malperfusion.

Figure 2 Survival distribution function for operated subgroup. For those patients surviving to operative repair, survival is similar for both patients initially presenting with uncomplicated acute dissection and those initially presenting with malperfusion and end-organ ischemia syndrome (UC 95.9 months vs MP 80.5 months; P = .45).
