Abstract
OBJECTIVES
We queried the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to review outcomes of acute limb ischemia (ALI) patients following open surgical intervention for ALI.
METHODS
A previously validated tool was used to identify ALI patients in NSQIP undergoing open surgical revascularization from 2012-2017. Multivariable analysis was performed for the primary outcome of reoperation and secondary outcome of readmission and infection.
RESULTS
2,878 ALI patients underwent open revascularization; 35.7% were transfers from another acute care hospital. 13.8% required reoperation and 7.9% required readmission within 30 days. 32% of reoperations were recurrent revascularization, representing 4.4% of all ALI patients. 58.7% of patients were female and either overweight or obese. Younger age (OR 0.991 [0.984-0.999], p=0.02), underweight patients (OR 1.159 [0.667-2.01], p=0.05), pre-operative steroid use (OR 1.61 [1.07-2.41], p=0.02), and perioperative transfusion (OR 2.02 [1.04-3.95], p=0.04) predicted reoperations.
CONCLUSIONS
This registry series demonstrates all-cause ALI patients are a different population than PAD with different risk factors. Despite being a time-critical condition, ALI has higher interhospital transfer rates than ACS or ruptured aneurysm. Following open revascularization, ALI outcomes are worse than ACS but better than ruptured AAA. These outcomes do not appear related to patient factors in contrast to revascularization for chronic PAD.
