For this reason, imaging studies are now considered more adequate for assessing the compromise created by the lesion, when used together with the clinical history of associated signs and symptoms such as orthopnea, stridor, dyspnea, etc.In a retrospective study of 98 patients with risk factors for intraoperative and postoperative complications, Bechard et al found a significant association with the mixed restrictive-obstructive pattern and the reduced peak expiratory flow in the flow-volume curve.
Bechard et al identificaron, en un estudio retrospectivo con 98 pacientes, los factores de riesgo de complicaciones intraoperatorias y postoperatorias; encontraron una asociación significativa con el patrón mixto restrictivoobstructivo y la reducción del flujo espiratorio pico de la curva flujo-volumen. Los pacientes con masas mediastinales anteriores deben tener en la valoración preoperatoria una TC de tórax.
