Abstract
BACKGROUND: This study aimed to demonstrate the safety and reliability of combined preoperative angioplasty and free flap transfer in patients with peripheral arterial occlusive disease (PAOD) by analyzing the surgical outcomes.
METHODS: Between October 2011 and October 2015, patients who had undergone lower extremity angiography and subsequent free flap transfer were retrospectively reviewed. Data collected included demographics, perioperative data, and postoperative outcomes. The cases were divided into two groups: one group with microanastomosis performed on revascularized artery by balloon angioplasty and the other group performed on native artery. Multiple logistic regression model using propensity score and linear regression was computed to determine the association between preoperative angioplasty and the surgical outcomes.
RESULTS: A total of 62 lower limb reconstruction cases (19 angioplastied cases and 43 nonangioplastied cases) were included in the study. Complications occurred in 6 cases in the angioplastied group and in 11 cases in the control group. The overall limb salvage rate was 100% during the average follow-up of 29.5 months in the angioplastied group and 97.7% in the nonangioplastied control group during the average follow-up of 31.1 months. Preoperative angioplasty was not a significant predictor of increased complications and longer postoperative downtime in logistic and linear regression model, both in the weighted and unweighted model.
CONCLUSIONS: The combined approach of preoperative endovascular revascularization and free flap transfer for limb reconstruction in PAOD patients can be performed safely and effectively with acceptable morbidity.
