影像学随访期间的可靠生长评估通常受限于直径测量的显著变化以及生长并不总是发生在标准测量位置的事实。需要基于成像的技术来更准确地评估生长。在这项研究中，我们调查了一个三维主动脉生长评估技术的可行性，以量化开放式主动脉repair.METHODSThree-dimensional主动脉生长的患者使用血管变形映射（VDM），一种技术，量化的局部率的体积生长在主动脉壁，每年雅可比（J）单位表示的主动脉生长进行了测量。我们纳入了16例患者，并分析了每例患者的6个主动脉节段（共96个节段）。通过3个指标评估生长：临床报告的直径、雅可比行列式和目标直径重新测量。ERTSVDM能够清楚地描述局部主动脉生长的存在或不存在，并允许评估生长的分布及其与解剖标志（例如，闭塞、分支动脉）的关系。与临床直径变化（r = 0.15，P = 0.141）相比，目标直径变化与J（r = 0.20，P = 0.047）显示出更强且显着的相关性。在20/96（21%）个通过VDM识别出生长的节段中，7个节段的生长通过临床测量得到证实，11个节段的靶向再测量得到证实。VDM和直径测量之间的增长评估协议是略高的有针对性的重新测量（κ = 0.38）相比，临床measurements（κ = 0.25）。使用VDM进行三维生长评估可提供更全面的生长评估，允许进行目标直径测量，并可作为确定哪些术后患者未来并发症风险较高和较低的附加工具。
OBJECTIVESConfident growth assessment during imaging follow-up is often limited by substantial variability of diameter measurements and the fact that growth does not always occur at standard measurement locations. There is a need for imaging-based techniques to more accurately assess growth. In this study, we investigated the feasibility of a three-dimensional aortic growth assessment technique to quantify aortic growth in patients following open aortic repair.METHODSThree-dimensional aortic growth was measured using vascular deformation mapping (VDM), a technique which quantifies the localized rate of volumetric growth at the aortic wall, expressed in units of Jacobian (J) per year. We included 16 patients and analysed 6 aortic segments per patient (96 total segments). Growth was assessed by 3 metrics: clinically reported diameters, Jacobian determinant and targeted diameter re-measurements.RESULTSVDM was able to clearly depict the presence or absence of localized aortic growth and allows for an assessment of the distribution of growth and its relation to anatomic landmarks (e.g. anastomoses, branch arteries). Targeted diameter change showed a stronger and significant correlation with J (r= 0.20,P= 0.047) compared to clinical diameter change (r= 0.15,P= 0.141). Among 20/96 (21%) segments with growth identified by VDM, growth was confirmed by clinical measurements in 7 and targeted re-measurements in 11. Agreement of growth assessments between VDM and diameter measurements was slightly higher for targeted re-measurements (kappa = 0.38) compared to clinical measurements (kappa = 0.25).CONCLUSIONSAortic growth is often uncertain and underappreciated when assessed via standard diameter measurements. Three-dimensional growth assessment with VDM offers a more comprehensive assessment of growth, allows for targeted diameter measurements and could be an additional tool to determine which post-surgical patients at high and low risk for future complications.
