Background: Popliteal vascular injuries are common and frequently associated with limb loss. Although many studies have evaluated the treatment and outcomes of popliteal artery injuries (PAI), there is little available evidence regarding popliteal venous injuries (PVI). As such, substantial debate remains regarding the benefit of repair over ligation of PVI. The objectives of this study were to compare in-hospital outcomes of repair versus ligation of isolated PVI, as well as to determine nonvascular factors associated with worse outcomes. Methods: Patients in the National Trauma Databank from 2007 to 2014 with at least one PVI were evaluated. First, patients with concomitant PVI and PAI were compared with patients with isolated PVI. Second, outcomes were compared between ligation and repair of isolated PVI. To limit the impact of concomitant injuries and focus on the impact of venous injury management, we defined isolated PVI as cases without concomitant PAI and with Abbreviated Injury Scale severity score of less than 3 for all body regions other than lower extremity. Patients dead on arrival and those with less than 18 years of age were excluded. The primary outcomes were in-hospital mortality, amputation, and in-hospital amputation-free survival (AFS). Secondary outcomes included lower extremity compartment syndrome, fasciotomy, acute kidney injury, pulmonary embolism, deep venous thrombosis, and inferior vena cava filter placement. Results: Overall, 1819 patients (0.03%) had a PVI and after exclusion 1213 met the criteria for initial analysis. Of those, 308 had isolated PVI, and 905 had combined PVI and PAI. Patients with combined PVI and PAI had higher rates of amputation (15.2% vs 6.8%; P <.001), fasciotomy (64.5% vs 30.8%; P <.001), compartment syndrome (14.8% vs 8.8%; P = .006), and a lower AFS (82.9% vs 91.8%; P <.001) than patients with isolated PVI. There was no difference in in-hospital mortality, amputation, or in-hospital AFS between ligation and repair of isolated PVI. On multivariable logistic regression of isolated PVI, ligation was not independently associated with in-hospital AFS, amputation, or mortality. Conclusions: Ligation of isolated PVI was not an independent predictor of in-hospital mortality, lower extremity amputation, or in-hospital AFS. Ligation also did not result in higher rates of fasciotomy, acute kidney injury, or pulmonary embolism.
