Abstract
- Skin perfusion pressure (SPP) has been proposed as a method to predict wound healing in chronic limb threatening ischaemia (CLTI). However, studies regarding the impact of SPP before and after endovascular therapy (EVT) on wound healing are limited. This study sought to evaluate the predictive value of SPP for early wound healing in CLTI treated by EVT. Between January 2018 and June 2020, 236 limbs (172 patients) with CLTI that underwent SPP measurement before and after EVT were included. SPP was measured before and 24 – 48 hours after the procedure. Early wound healing was defined as the achievement of complete epithelisation of all wounds without major amputation within three months of EVT. Early wound healing was achieved in 145 (61.4%) limbs after EVT. Baseline SPP (44.1 ± 21.0 mmHg vs. 33.5 ± 21.7 mmHg; p <.001) and post-procedural SPP (61.8 ± 18.5 mmHg vs. 37.4 ± 19.9 mmHg; p <.001) were significantly higher in the wound healing (+) group than in the wound non-healing (-) group. The area under the receiver operating characteristics curve for early wound healing was 0.82 for post-procedural SPP with a cutoff value of 50 mmHg (sensitivity 74.5%, specificity 78.0%). The early wound healing rate was significantly higher with a post-procedural SPP ≥ 50 mmHg compared with a SPP < 50 mmHg (84.4% vs. 35.0%; p <.001). Post-procedural SPP with a cutoff value of 50 mmHg was capable of predicting early wound healing after EVT in CLTI. [ABSTRACT FROM AUTHOR]
