When taken to mastectomy, breast reconstruction is an integral part of treatment.  Objectives: The purpose of this study is to determine which factors are associated to post-operatory complications of breast reconstruction in patients with breast cancer treated with mastectomy.  Methods: 306 patients taken to breast reconstruction were divided into three groups depending on technique: pedicled flaps, prosthetic material and deep inferior epigastric perforators (DIEP). Descriptive and comparative statistics were performed to find associations between the type of reconstruction and complications.  Results: The factors associated to general were bleeding and reintervention. Reintervention was associated to loss of reconstruction. Factors associated to reoperation were immediate complications, late complications, and radiotherapy. Factors associated to loss of reconstruction where smoker status, presence of late complications, and reintervention.  Conclusion: There is a higher percentage of immediate complications and loss of reconstruction with prosthetics. DIEP is an alternative with lower probability of loss of reconstruction. Multidisciplinary teams should establish the decision of the best type of reconstruction.]]></p></abstract>

Cuando son llevadas a mastectomía, la reconstrucción mamaria es también una parte integral del tratamiento.  Objetivos: Determinar factores asociados a complicaciones postoperatorias de reconstrucción mamaria en pacientes con cáncer de mama tratadas con mastectomía.  Métodos: 306 pacientes llevadas a reconstrucción mamaria fueron divididas en tres grupos dependiendo de la técnica: colgajo pediculado, prótesis y colgajo DIEP. Se realizaron análisis descriptivos y comparativos entre el tipo de reconstrucción y las complicaciones postoperatorias.  Resultados: Los factores asociados a complicaciones en general fueron sangrado y reintervención. Los factores asociados a la reintervención fueron complicaciones inmediatas, tardías y radioterapia. Los factores asociados a la pérdida de la reconstrucción fueron el tabaquismo, complicaciones tardías y reintervención.  Conclusión: Hay un mayor porcentaje de pacientes con complicaciones inmediatas y pérdida de la reconstrucción en técnicas que involucran prótesis. El colgajo DIEP es una alternativa con menor probabilidad de pérdida de la reconstrucción. Un equipo multidisciplinario debe decidir el mejor tipo de reconstrucción para cada paciente.]]></p></abstract>
