to analyze the changes in the width of selected veins in the lower limbs during pregnancy and puerperium, with or without venous insufficiency (VI) diagnosed at the first trimester
the group of 100 pregnant was divided into two subgroups with or without VI. The examination was performed, namely between 11-14th, 18-22nd, 28-32nd weeks of gestation and in 6th week of the puerperium. The sonographic examination included the measurement of the transverse diameter (TD) of the common femoral vein (CFV), the superficial femoral vein (SFV) and the popliteal vein (PV). The changes in the vessel width during pregnancy and puerperium were compared in both groups. Moreover the changes of analyzed ultrasound parameters between the two groups in the 4 analyzed time periods were compared to the first trimester results.
there was a statistically significant increase in the TD of CFV with the highest values in the third trimester and significantly higher in the puerperium compared to the first visit. TD in all analyzed stages of pregnancy in the group with VI was significantly higher SFV and PV were not statistically different between the groups in any of the analyzed periods. Average TD of these vessels was higher in the third trimester decreasing gradually during the postpartum period.
The average TD was highest in the third trimester decreasing during the postpartum period. In VI group a full return of TD to the values observed in the first trimester was not observed in the puerperium.
分析妊娠和产褥期下肢选定静脉的宽度变化，无论在孕早期是否诊断为静脉功能不全（VI）
100名孕妇分为有或无VI的两个亚组。检查分别在妊娠第11 - 14周、18 - 22周、28 - 32周以及产褥期第6周进行。超声检查包括测量股总静脉（CFV）、股浅静脉（SFV）和腘静脉（PV）的横径（TD）。比较两组妊娠和产褥期血管宽度的变化。此外，将两组在4个分析时间段内分析的超声参数变化与孕早期结果进行比较。
CFV的TD有统计学显著增加，在妊娠晚期最高，与首次就诊相比，产褥期显著更高。VI组在妊娠所有分析阶段的TD均显著更高，SFV和PV在任何分析时间段内两组之间无统计学差异。这些血管的平均TD在妊娠晚期较高，产后逐渐降低。
平均TD在妊娠晚期最高，产后降低。在VI组中，产褥期TD未完全恢复到孕早期观察到的值。
