To assess the placental elasticity using point shear wave velocity (pSWV) in pregnant women who had recovered from coronavirus COVID-19.
A total of 40 pregnant women who had recovered from moderate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and 40 healthy pregnant women were included in this study. We evaluated placental elasticity by using transabdominal pSWV method. Three measurements were made, and their average was accepted as the mean placental velocity value in each case. The results were compared between the post-COVID-19 and control groups.
The mean pSWV values were significantly higher in the post-COVID-19 group compared to the control group, indicating that the women with a history of COVID-19 had stiffer placentas. Furthermore, the pSWV values were significantly and positively correlated with the uterine artery pulsatility index. We also found that the NICU requirement was statistically higher in the post-COVID 19 group.
The pregnant women who had recovered from COVID-19 had rigid placentas than the healthy controls. The use of pSWV for the assessment of placental velocity may provide valuable information in the diagnosis and management of post-COVID-19 patients as a complementary tool to the existing ultrasonography methods.
评估冠状病毒 COVID-19 康复后孕妇的胎盘弹性，使用点剪切波速度 (pSWV)。
本研究共纳入 40 名从中度严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）中康复的孕妇和 40 名健康孕妇。我们使用经腹 pSWV 方法评估胎盘弹性。进行了三次测量，其平均值被接受为每个病例的平均胎盘速度值。将结果在 COVID-19 后组和对照组之间进行比较。
与对照组相比，COVID-19 后组的平均 pSWV 值明显更高，表明有 COVID-19 病史的女性胎盘更硬。此外，pSWV 值与子宫动脉搏动指数呈显著正相关。我们还发现 COVID-19 后组的新生儿重症监护病房需求在统计学上更高。
从 COVID-19 中康复的孕妇的胎盘比健康对照组更硬。使用 pSWV 评估胎盘速度可能为 COVID-19 后患者的诊断和管理提供有价值的信息，作为现有超声方法的补充工具。
