Thirty-six patients with aortoiliac reconstruction were studied by magnetic resonance imaging (MRI) to determine the diameter, baseline signal, and subsequent magnetic signal characteristics of postoperative periprosthetic collection (PPC). Our study confirmed the presence of PCC in most cases (32/36). The diameter was significantly (p < 0.05) correlated with the type of disease being treated, the type of proximal anastomosis created, and whether or not drainage and postoperative transfusion were used. PPC usually disappeared within 3 to 6 months postoperatively. Modifications of magnetic signals T1 and T2 require approximately the same amount of time to diminish. During follow-up investigations in this series, there was one case of prosthetic infection characterized by the persistence of PPC and a strong T2 signal 6 months after surgery, the latter corresponding to incomplete or delayed healing. The MRI aspects of normal healing of aortic grafts were analyzed to correctly interpret the MRI aspects of complications in surgery of the aorta.
对36例行主-髂动脉重建术的患者进行了磁共振成像（MRI）检查，以确定术后假体周围积液（PPC）的直径、基线信号及后续磁信号特征。我们的研究证实，大多数病例（32/36）存在PCC。其直径与所治疗疾病的类型、近端吻合口的类型以及是否使用引流和术后输血显著相关（p < 0.05）。PPC通常在术后3至6个月内消失。磁信号T1和T2的改变减弱所需时间大致相同。在本系列随访研究中，有1例假体感染，其特征为术后6个月PPC持续存在且T2信号增强，后者对应愈合不全或延迟愈合。分析了主动脉移植物正常愈合的MRI表现，以正确解读主动脉手术并发症的MRI表现。
