Trauma vascular na população pediátrica

Pediatric vascular trauma in Manaus, Amazon - Brazil

Objective:

to assess the incidence of pediatric vascular injuries in patients treated at the Emergency Room of the Eastern Children's Hospital, in Manaus.

Methods:

we conducted a retrospective study of pediatric patients who suffered vascular injuries treated between February 2001 to February 2012.

Results:

we studied 71 patients, predominantly male (78.87%), with a mean age of 7.63 years. The predominant mechanism of injury was stab wound in 27 patients (38.03%). The average hospital stay was 10.18 days; 16 patients required care in intensive care unit, with average stay of 8.81 days. The main injuries occurred in the extremities, the upper limb being the most affected, with lesions of the ulnar artery in 13 (15.66%) and radial in 10 (12.04%). The mostly applied procedure was vascular exploration 35 (32.4%). Complications occurred in nine patients (12.68%). Mortality was 1.4%, in one patient with a lesion of the common iliac vein and the inferior vena cava due fall from height.

Conclusion:

pediatric vascular injury occurred predominantly in the extremities. The dimensions of the injured vessels made surgical correction more complex and increased complication rates, particularly amputations.

Objetivo:

avaliar a incidência de traumatismos vasculares pediátricos em doentes atendidos no Hospital Pronto Socorro da Criança Zona Leste, na cidade de Manaus.

Métodos:

estudo retrospectivo de doentes pediátricos vítimas de traumatismos vasculares atendidos no período de fevereiro de 2001 a fevereiro de 2012.

Resultados:

foram estudados 71 doentes com predominância do sexo masculino (78,87%) com média de idade de 7,63 anos. O mecanismo de trauma predominante foi o ferimento por arma branca em 27 pacientes (38,03%). A média de internação foi 10,18 dias, com 16 doentes necessitando de cuidados em unidade de tratamento intensivo com permanência média de 8,81 dias. As principais lesões ocorreram em extremidades, com predomínio do membro superior, com lesões das artérias ulnar em 13 (15,66%) e radial em dez (12,04%). O procedimento mais utilizado foi a exploração vascular 35 (32,4%). Em nove doentes (12,68%) ocorreram complicações. A mortalidade foi 1,4%, em um paciente com lesão da veia ilíaca comum e da veia cava inferior, devido à queda de altura.

Conclusão:

o traumatismo vascular pediátrico ocorreu predominantemente em extremidades. As dimensões dos vasos lesionados tornaram a correção cirúrgica mais complexa e aumentaram os índices de complicações, particularmente, de amputações.

Vascular trauma in the Amazon - the challenge of great distances

OBJECTIVE

to evaluate the incidence of unfavorable outcomes in vascular trauma patients and their possible correlation to the distance between the city where the injury was sustained and the hospital where the patient received definitive treatment.

METHODS

descriptive and retrospective study. Data were collected from medical records of patients submitted to surgical procedures for arterial or venous injuries from February 2011 to February 2013 at the only trauma center providing vascular surgery in a vast area of the Amazon region. Trauma date, patient gender and age, mechanism and anatomic topography of injury, surgical management, need for surgical re-intervention, hospitalization period, postoperative complications, mortality and limb amputation rates were analyzed. The incidence of unfavorable outcomes was assessed according to the distance between the city where the vascular injury was sustained and the trauma center.

RESULTS

One hundred seventy-three patients with 255 vascular injuries were analyzed; 95.95% were male (p<0.05), mean age of 28.92 years; 47.4% were caused by firearm projectiles (p<0.05); topographic distribution: 45.66% lower limbs (p<0.05), 37.57% upper limbs, 6.94% abdominal, 5.2% thoracic and 4.62% were cervical vascular injuries; 51.42% of patients required hospitalization for seven days or less (p<0.05); limb amputation was necessary in 15.6% and the overall mortality was 6.36%.

CONCLUSION

distances greater than 200 Km were associated to longer hospitalization period; distances greater than 300 Km were associated to increased limb amputation probability; severe vascular trauma have an increased death probability when patients need to travel more than 200 Km for surgical treatment.

Vascular injuries in the state of Pará, Brazil, 2011-2013 and their relation with demographic and clinical variables

BACKGROUND:Vascular traumas are associated with high morbidity rates.OBJECTIVE: To report the characteristics of vascular traumas in the Brazilian state of Pará, in trauma victims treated at the Hospital Metropolitano de Urgência e Emergência (HMUE), from 2011 to 2013.METHOD: This was a descriptive, cross-sectional, retrospective and quantitative study that analyzed data on sex, age group, geographical origin, time waiting for care, mechanism of trauma, clinical status, anatomic site of injury, prevalence of associated fractures, vascular structures injured, types of vascular injury, principal types of surgery, early postoperative outcomes, level of amputation, number of deaths, length of hospital stay and multidisciplinary care for 264 medical records.RESULTS: The majority of victims were male and the most common age group was from 16 to 30 years. The majority of cases were from towns other than the state capital, accounting for 169 cases (64.02%). The principal mechanism of injury was firearm wounding - 110 (41.67%) followed by cold weapon wounds - 65 (24.62%) and traffic accidents - 42 (15.91%). The segments of the body and the vascular structures most often injured were lower limbs - 120 (45.45%) and injuries to the popliteal and femoral arteries and veins. The most common clinical presentation at admission was hemorrhage - 154 (58.33%). The most common surgeries were ligatures of veins and arteries. There were 163 (61.74%) hospital discharges and 33 (12.5%) deaths.CONCLUSIONS: The greatest prevalence observed was related to traumas caused by urban violence. Victims were most frequently male, of working age and from towns other than the capital of the state of Pará.
