Long-term outcomes after pediatric peripheral revascularization secondary to trauma at an urban level I center.

The purpose of this investigation was to determine our limb-related contemporary pediatric revascularization perioperative and follow-up outcomes after major blunt and penetrating trauma. A retrospective review was performed of a prospectively maintained pediatric trauma database spanning January 2010 to December 2017 to capture all level I trauma activations that resulted in a peripheral arterial revascularization procedure. All preoperative, intraoperative, and postoperative continuous variables are reported as a mean ± standard deviation; categorical variables are reported as a percentage of the population of interest. During the study period, 1399 level I trauma activations occurred at a large-volume, urban children's hospital. The vascular surgery service was consulted in 2.6% (n = 36) of these cases for suspected vascular injury based on imaging or physical examination. Our study population included only patients who received an arterial revascularization, which was performed in 23 of the 36 consultations (1.6% of total traumas; median age, 11 years). These injuries were localized to the upper extremity in 60.9% (n = 14), lower extremity in 30.4% (n = 7), and neck in 8.7% (n = 2). The mean Injury Severity Score in the revascularized cohort was 14.0 (±7.6). Bone fractures were associated with 39.1% of the vascular injuries (90% of blunt injuries). Restoration of in-line flow was achieved by an endovascular solution in one patient and open surgery in the remainder, consisting of arterial bypass in 59.1% and direct repair in 40.9%. Within 30 days of the operation, we observed no deaths, no infections of the arterial reconstruction, and no major amputations. One patient required perioperative reintervention by the vascular team secondary to the development of a superficial seroma without evidence of graft involvement. Mean follow-up in our cohort was 43.3 (±35.4) months. During this phase, no additional deaths, amputations, chronic wounds, or limb length discrepancies were observed. All vascular repairs were patent, and all but one patient reported normal function of the affected limb at the latest clinic visit. Traumatic peripheral vascular injury is rare in the pediatric population but is often observed secondary to a penetrating force or after long bone fracture. However, contemporary perioperative and long-term outcomes after surgical revascularization are excellent as demonstrated in this institutional case series.

Vascular Trauma in Children-Review from a Major Paediatric Center.

Traumatic noniatrogenic vascular injuries in children are rare and rarely discussed in literature. Pediatric vascular injuries pose a set of challenges mainly because of continued growth and development in a child or adolescent. The purpose of the study is to characterize management strategies and outcomes in these cases. This is a single-center retrospective review of patients less than age 18 years (pediatric age) with acute, noniatrogenic traumatic vascular injuries between January 2009 and December 2015. Patient's demographics, injury characteristics, surgical management, complications, and follow-up were analyzed. From 2009 to 2015, 3277 children with traumatic injuries were treated, of which 21 (0.6%) had 23 significant vascular injuries: 17 arterial and 6 venous injuries. The majority were males (n = 16), and the median age was 14 years (range 1 to 16 years). Penetrating injuries were the predominant mechanism (n = 21), mainly by glass (n = 13). At presentation, 4 patients were hemodynamically unstable, 3 of them in hypovolemic shock. All patients were managed operatively. Operations for arterial injuries included 5 primary arterial repairs, 4 repairs using vein grafts and 8 ligations. The following adjunct procedures were necessary: one 4-compartment leg fasciotomy due to associated soft tissue trauma, 8 tendon repairs, and 11 nerve repairs. Operations for venous injuries included 4 ligations and 2 primary repairs. There were no intraoperative or postoperative deaths, major complications, or limb loss. The median length of stay in the hospital was 6 days (range: 2-23 days). The median time of follow-up was 52 months (range: 20-94 months). Ten patients did not have any sequelae, and 11 patients reported impaired mobility and/or decreased sensation, which was transitory in most cases and related to associated neurological or muscle tendon injuries. All reconstructions remained patent over the course of follow-up. No limb asymmetry was observed. Noniatrogenic pediatric vascular trauma is uncommon. Penetrating mechanism is more common than blunt and extremities are more frequently affected. Overall complications come from associated injuries to tendons and nerves.

Contemporary outcomes of civilian lower extremity arterial trauma.

Lower extremity arterial injury may result in limb loss after blunt or penetrating trauma. This study examined outcomes of civilian lower extremity arterial trauma and predictors of delayed amputation. The records of patients presenting to a major level I trauma center from 2004 to 2014 with infrainguinal arterial injury were identified from a prospective institutional trauma registry, and outcomes were reviewed. Standard statistical methods were used for data analysis. We identified 149 patients (86% male; mean age, 33 ± 14 years,). Of these, 46% presented with blunt trauma: 19 (13%) had common femoral artery, 26 (17%) superficial femoral artery, 50 (33%) popliteal, and 54 (36%) tibial injury. Seven patients underwent primary amputation; of the remainder, 21 (15%) underwent ligation, 85 (59%) revascularization (80% bypass grafting, 20% primary repair), and the rest were observed. Delayed amputation was eventually required in 24 patients (17%): 20 (83%) were due to irreversible ischemia or extensive musculoskeletal damage, despite having adequate perfusion. Delayed amputation rates were 26% for popliteal, 20% for tibial, and 4.4% for common/superficial femoral artery injury. The delayed amputation group had significantly more (P < .05) blunt trauma (79% vs 30%), popliteal injury (46% vs 27%), compound fracture/dislocation (75% vs 33%), bypass graft (63% vs 43%), and fasciotomy (75% vs 43%), and a higher mangled extremity severity score (6.1 ± 1.8 vs 4.3 ± 1.6). Predictors of delayed amputation included younger age, higher injury severity score, popliteal or multiple tibial injury, blunt trauma, and pulseless examination on presentation. Individualized decision making based on age, mechanism, pulseless presentation, extent of musculoskeletal trauma, and location of injury should guide the intensity of revascularization strategies after extremity arterial trauma. Although patients presenting with vascular trauma in the setting of multiple negative prognostic factors should not be denied revascularization, expectations for limb salvage in the short-term and long-term periods should be carefully outlined.
