Trauma vascular na popula？？o pediátrica

background: vascular trauma in the pediatric population is a unique challenge, mainly due to its relatively low incidence, even in high complexity medical centers. due to the fragility of the tissues, the small size of vessels and low incidence, it manifests with significant rates of morbidity and mortality. objective: to describe and analyze the cases of vascular trauma in pediatric patients admitted to a tertiary hospital. methods: through retrospective study we analyzed the cases of vascular trauma in patients younger than 18 years, admitted from january 2000 to july 2010, taking into account demographic data, mechanisms of injury, associated injuries, treatment techniques and complications. results: during the studied period, 242 patients were admitted with vascular trauma, 37 (15.2%) belonging to the pediatric population. the average age was 12.5 years, and 81% of the research participants were male. related to the mechanisms of injury, penetrating trauma was the most common (57%), followed by blunt (38%) and iatrogenic (5%). among the surgical techniques employed, arterial bypass with autologous vein was the most common (13 cases). there was a case of primary major amputation (below the knee) and four amputations in the early postoperative period (three transfemoral and one transtarsic). for the 11 patients admitted with popliteal artery injury, the rate of postoperative transfemoral amputation was 27.3%. there was only one death due to an iatrogenic trauma in a hemophilic lactant. conclusions: vascular trauma in pediatric patients involves several technical challenges, such as vasospasm and vessel diameter. the high rates of amputation in patients with popliteal artery injuries, despite attempts of revascularization, reinforce the seriousness of this type of trauma.
