Résumé
Objetivo: Conocer la prevalencia y factores de riesgo de complicaciones en safenectomía de pacientes postoperados de revascularización miocárdica, en el Departamento de Cirugía Cardiotorácica. Diseño: Estudio prospectivo, transversal, descriptivo y comparativo. Análisis estadístico: Medidas de tendencia central y t de Student. Pacientes y métodos: Se estudiaron pacientes sometidos a revascularización miocárdica entre el 1 de enero y el 31 de octubre del 2011, en los que se utilizó vena safena como injerto libre, con o sin uso adicional de arteria mamaria interna izquierda. La obtención del injerto fue a través de múltiples incisiones. Fueron consideradas como complicaciones: hematoma, infección, edema, rechazo de material de sutura, dehiscencia, necrosis, celulitis, dermatitis, trombosis, seroma, síndrome compartimental. Se comparó número de incisiones, longitud de incisiones, obtención de vena safena inversa, tiempo quirúrgico y pinzamiento de aorta, entre los pacientes complicados y los no complicados. Resultados: En el periodo de estudio, en 150 pacientes (129 hombres y 21 mujeres), se realizó safenectomía para utilizar la vena safena como injerto libre. La edad promedio fue 61 ± 9.48 años. La prevalencia de complicaciones fue de 29%. Correspondiendo a hematoma 19% (n = 29), infección del sitio quirúrgico 4.6% (n = 7), edema 2% (n = 3), reacción al material de sutura 1.3% (n = 2) y dehiscencia 2% (n = 3). No existió diferencia estadística entre las variables evaluadas entre pacientes complicados y no complicados. Conclusiones: La prevalencia de complicaciones en la safenectomía para revascularización miocárdica es baja y se encuentra en los rangos aceptados en la literatura médica. No identificamos factores de riesgo.
Objective: To know the prevalence and risk factors for complications of saphenous vein harvesting for myocardial revascularization in patients operated at the Department of Cardiothoracic Surgery. Design: Prospective, cross-sectional, descriptive, and comparative study. Statistical analysis: Central tendency measures and Student's t test. Patients and methods: We studied patients subjected to myocardial revascularization between January 1st and October 31st 2011, in whom the saphenous vein was harvested to be used as free graft, with or without using additionally the left internal mamary artery. The graft was obtained through multiple incisions. Hematoma, infection, edema, suture material rejection, dehiscence, necrosis, cellulitis, dermatitis, thrombosis, seroma, compartmental syndrome were considered complications. We compared the number of incisions, length of incisions, inverse saphenous vein obtainment, surgical time and aorta clamping between complicated and non-complicated patients. Results: In the studied period, 150 patients (129 men and 21 women) were subjected to saphenous vein harvesting to be used as a free graft. Average age was of 61 ± 9.48 years. Prevalence of complications was of 29%, corresponding 19% (n = 29) to hematoma, 4.6% (n = 7) to infection of the surgical site, 2% (n = 3) to edema, 1.3% (n = 2) to reaction of the suture material, and 2% (n = 3) to dehiscence. No statistical difference was found in the variables between complicated and non-complicated patients. Conclusions: Prevalence of complications in saphenous vein harvesting for myocardial revascularization was low, and was within the ranges accepted in the medical literature. We did not identify risk factors.
Résumé
BACKGROUND: Uncontrolled bleeding leads to 40-86% of preventable deaths due to trauma. Use of NovoSeven (rFVIIa) in trauma is promising, although data supporting its utilization are limited. CASE REPORT: We report the case of a patient who sustained a penetrating grade V cardiac injury (AAST-OIS) and presented postoperative massive coagulopathic bleeding arrested by the administration of platelet pools and NovoSeven. DISCUSSION: This report represents our initial experience and the very first case of successful use of NovoSeven for the treatment of traumatic coagulopathic hemorrhage at the Central Military Hospital in Mexico City. A further prospective trial justifying its use in our institution is warranted.
