Impact of ligation versus repair of isolated popliteal vein injuries on Deep Vein Thrombosis and Pulmonary Embolism incidence in trauma patients: a meta-analysis.

Abstract

Traumatic injuries affecting the veins in the lower extremities have been correlated with both mortality and severe complications. Venous injuries are recognized as a contributing factor to the development of venous thromboembolism, commonly treated through procedures involving either vein ligation or repair. Despite previous efforts, substantial uncertainty remains when it comes to choosing between the execution of ligation versus various reparative techniques. The aim of this study was to evaluate the short-term results of surgically treating traumatic venous injuries through repair compared to ligation, specifically examining the resulting impacts on trauma patients in relation to DVT and PE occurrences. A comprehensive search strategy was employed until August 10, 2023, to systematically explore Scopus and PubMed databases. Following the removal of duplicates, two researchers independently assessed the titles and abstracts of the identified studies. Only studies meeting the project's requirements and inclusion criteria, as evaluated through their full texts, were included in our investigation. Our study exclusively focused on original articles, specifically those involving human trauma patients with isolated popliteal vein injuries. Excluded from consideration were review articles, meta-analyses, cellular and molecular research, animal studies, case reports, case series, letters to the editor, posters, duplicates, and publications in languages other than English. The implementation of this systematic review and meta-analysis conformed to the standards delineated in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Conducting a thorough search, the inquiry identified 248 records. The assessment of titles and abstracts led to 51 studies that had the potential for eligibility. After reviewing the full texts of the chosen studies, 4 studies involving 1521 patients constituted the ultimate findings. We concluded that the ligation procedure had a higher incidence of pulmonary embolism compared to the repair of vein injuries, while the repair procedure had a higher incidence of deep vein thrombosis than ligation. Additional large-scale randomized controlled trials are still necessary to further support the findings of this meta-analysis.
