| Popis: | The pathogenesis of anastomotic femoral pseudoaneurysms (AFPs) is still unclear. We have performed this long-term retrospective study of patients who underwent aortobifemoral reconstruction for abdominal aortic aneurysm (AAA) in order to better establish the long-term rate of AFP and to identify the predictors of its late occurrence.The long-term outcome of 178 patients who underwent and survived aortobifemoral reconstruction for infrarenal AAA was reviewed.During a median follow-up of 5.2 years, 28 AFPs developed in 19 patients. Six AFPs were recurrent. The mean linearized rate of AFPs was 1.88% per year. At 15 years, the survival-freedom rate from AFPs was 60%, and from repair of AFPs it was 62%. The survival-freedom rate from AFP was significantly poorer in patients with chronic obstructive pulmonary disease (P = 0.017; at 10 years: 64.3% versus 92.3%), hyperlipidemia (P = 0.0056; at 10 years: 59.2% versus 87.5%), current smoking (P0.0001; at 10 years: 65.8% versus 94.5%), and postoperative inguinal wound infection (P0.0001; at 10 years: 42.8% versus 86.8%). Multivariate analysis showed that chronic obstructive pulmonary disease (relative risk [RR]: 3.05, 95% confidence interval [CI]: 1.04 to 8.95), current smoking (RR: 5.38, 95% CI: 1.62 to 17.90), and postoperative inguinal wound infection (RR: 9.04, 95% CI: 2.76 to 29.96) were significantly associated with the development of AFPs. The linearized rate of AFPs was significantly higher only among current smokers (P0.0001, 4.4% versus 0.8% per year) and among those who had inguinal wound infection (P = 0.001, 9.2% versus 1.5% per year).Current smoking and inguinal wound infection may contribute to the development of AFP after aortobifemoral reconstruction for AAA, likely by affecting reparative connective tissue mechanisms at the anastomotic site. |
