Background
We retrospectively assessed the initial clinical role of preoperative frailty in surgical patients with Stanford type A acute aortic dissection (AAAD).
Methods
One hundred and fourteen consecutive patients who underwent emergent or urgent surgical interventions for AAAD in our institute between April 2000 and March 2016 participated in this retrospective study. Patients with more than three of the following six modalities were defined as being frail: age older than 75 years, preoperative requirement of assistance in daily living, body mass index less than 18.5 kg/m2, female, history of major stroke, and chronic kidney disease greater than class 3b. Twenty-three patients (20.2%) were diagnosed with frailty (group F), while 91 patients (79.8%) were not (group N). Early clinical outcomes, major postoperative complications, postoperative recovery of activity, and early or mid-term survival were evaluated.
Results
Although early clinical outcomes and the prevalence of major postoperative complications were similar in both groups, postoperative activity of daily living (ADL), such as the rate of being ambulatory on discharge (p < 0.05) and home discharge (p < 0.01), was significantly lower in group F than in group N. A Kaplan–Meier analysis revealed that 1- and 5-year survival rates were similar in groups F (85.9 and 76.4%, respectively) and N (86.0 and 76.9%, respectively).
Conclusions
Preoperative frailty in AAAD surgical patients has potential as a prognostic factor that affects delays in ADL recovery, but does not influence the early or mid-term clinical outcomes of prompt surgical strategies for life rescue in AAAD patients with frailty.
