Abstract
Popliteal artery injury is a severe condition that can lead to limb loss. Early intervention is essential to achieve optimal outcomes, including limb salvage. The Mangled Extremity Severity Score (MESS) is a scoring system used to predict amputation rates for mangled limb injuries. The effectiveness of the MESS in predicting amputationin patients with traumaticpopliteal artery injury is unclear, particularly in settings with a high prevalence of motorcycle accidents. This retrospective study was conducted at a single center in Vietnam between January 2018 and June 2020. The study included 120 patients who underwent surgical treatment for popliteal artery injury. Data were collected from electronic medical records, radiology reports, and operative notes. Logistic regression model and the area under the curve (AUC) were used to evaluate the predictive value of the MESS. Patients with a MESS score of ≥8 had a higher rate of amputation compared to those with a MESS score of <8. However, the predictive value of the MESS was limited, with an AUC of 0.68. Higher skeletal/soft tissue injury score, limb ischemia score, and shock score were associated with a higher risk of amputation. The age score of the MESS was unexpectedly higher in the limb salvage group. The MESS score can be useful in predicting amputation rates in patients with popliteal artery injury, but its predictive value is limited. A team approach involving experienced surgeons is recommended for decision-making regarding amputation.
