Background: The aim of this study was to investigate surgical indications and the long-term outcomes of aoroiliofemoral reconstructions in adults younger than 45 years.
Methods: Between 1973 and 1990, 1256 patients underwent infrarenal abdominal aortic reconstruction for aortoiliofemoral occlusive disease. Sixty-eight (5.4%) patients (group 1) were less than 45 years old and form the basis of the analysis. They were retrospectively compared with two additional groups of patients 45 years and older selected from the entire series. Patients in group 2 (n = 100) were randomly chosen to determine differences in risk factors, associated diseases, operative indications, preoperative findings, and outcomes. Patients in group 3 (n = 70) were matched with those in group 1 for gender, risk factors, associated diseases, preoperative findings, and operative indications to assess the importance of age in determining the short- and long-term outcomes of aortoiliofemoral reconstructions.
Results: Postoperative mortality rates (1.5%, 4%, and 4.3% for groups 1, 2, and 3, respectively) and major complication rates (4.4%, 7%, and 7.1% for groups 1, 2, and 3, respectively) were comparable among the three groups. Ten-year secondary patency rates were 84.6%, 70.6%, and 80.3%, for groups 1, 2, and 3, respectively (p = not significant). Ten-year limb salvage rates were 86.9%, 78.2%, and 80.6%, for groups 1, 2, and 3, respectively (p = not significant). During follow-up a significantly higher percentage of myocardial infarction was recorded in group 1 as compared with group 2 (p < 0.03) and group 3 (p < 0.04). The 10-year survival rate for group 1 was significantly lower than that of group 2 (29.0% versus 46.9%; p < 0.005).
Conclusions: Aortoliofemoral reconstruction in patients younger than 45 years is a safe procedure with low operative risks and good long-term results in patency and limb salvage rates. However, life expectancy is poor because of the high incidence of deaths related to coronary artery disease.
