Abstract
BackgroundThe purpose of this study was to investigate if the duration of bilateral acute limb ischaemia (BALI) caused by acute aortic occlusion (AAO) affected amputation-free survival. Materials and methodsA retrospective analysis of patients treated between 1 January 2010 and 1 January 2019 for primary occlusion of the infrarenal aorta and BALI was performed. Univariate analysis was used to determine the risk factors for adverse outcomes and compare the duration of BALI between the amputation-free survival and non-amputation-free survival groups. ResultsThe data from 16 patients with a mean age of 70 ± 11 years were analysed. Predominantly females (56.3%, 9/16) were included in the study. Out of 16 patients, nine had Rutherford grade IIb, and seven had Rutherford grade III at admission. Seven patients underwent revascularisation attempts, two underwent primary major amputation, and seven underwent primary palliation. The mean ischaemia time was significantly shorter in the amputation-free survival group than in the non-amputation-free survival group (7.4 ± 3.5 h vs 22.4 ± 16.3 h, p = .01). The time frame for successful bilateral lower limb revascularisation was <11 h (p = .03). ConclusionsThe duration of BALI due to AAO of <11 h was shown to be associated with improved amputation-free survival.
