Background: Digit amputation is rare in pediatric trauma but can lead to functional morbidity. The true incidence of digital arterial injury is lacking in the literature, and revascularization techniques are not well-described.
Methods: Retrospective review of a pediatric trauma registry identified patients with a digital artery injury between July 2008 and December 2013. Isolated vein injuries and arterial injuries proximal to the digits were excluded. Descriptive statistics were used.
Results: Twenty-five subjects met inclusion. Most were male (n=16; 64%) and the median age was 6.8 (IQR: 2.8, 11.1) years. The most common blunt (n=12) trauma was struck/crushed by object (n=4; 33%) and the most common penetrating (n=13) trauma was because of glass (n=9; 69%). All subjects were managed operatively. Initial operations for arterial repair were primary arterial repair (15; 20%), vein graft (7; 28%), thrombectomy (1; 4%), and amputation (1; 4%). Twelve patients (48%) had reported complications at initial follow-up, but only two (8%) had long-term (>24weeks) sequelae.
Conclusion: Digital artery injury is rare among pediatric traumas. Functional outcomes after digital artery revascularization are favorable. Primary repair can successfully manage these injuries and vein grafting appears to be a suitable alternative when primary repair is not feasible.
