Abstract
BACKGROUND
Perforator propeller flaps (PPFs) have been widely used due to their numerous advantages; however, they were also associated with various complications. Herein, we analyzed the risk factors for complications of PPFs used for soft tissue reconstruction after malignant tumor resection.
METHODS
We searched databases for articles on soft tissue reconstruction using PPFs after malignant tumor resection published between January 1991 and April 2021. Studies were selected according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. Fixed effects models and relative risks were used for data analysis. Funnel plots and Begg's test were used to evaluate publication bias.
RESULTS
Twenty-six articles met the inclusion criteria. Complications were found in 24.7% of all patients. The four significant risk factors were age equal or older than 60 years (pooled relative risk, 1.83; p = .04), smoking (pooled relative risk, 2.32; p = .03), diabetes (pooled relative risk, 2.59; p = .01) and radiotherapy (pooled relative risk, 2.09; p = .01). Hypertension, defects located in the extremities, flap size equal or greater than 100 cm2 , and pedicle rotation equal or greater than 120 degrees were not significant risk factors for complications. No publication bias was found in the included articles.
CONCLUSION
Age equal or older than 60 years, smoking, diabetes and radiotherapy are four risk factors for complications when PPFs are used to reconstruct soft tissue defects resulting from malignant tumor resection.
