摘要

目的:评估用于测量剖宫产术后切口部位产褥期子宫肌层微血管血流的超级微血管成像技术:研究对象为 20 名产后妇女(单胎):10 名剖宫产,10 名经阴道分娩。所有剖宫产病例均为首次手术分娩,子宫下段切口用双层缝合线修补。在产后1周和4周,使用经阴道超声波和超微血管成像对子宫进行划定。峡部前方子宫肌层和子宫体分别为不同的观察区域。对感兴趣区内三个圆形取样点的微血管流动情况进行量化,并以血管密度表示。两组子宫峡部和子宫体的血管密度比在一周和四周之间进行比较。采用 Wilcoxon 符号秩检验来评估统计显著性(以 p 为结果):在剖宫产中,子宫峡部与子宫体的血管密度比值从1周(中位数:0.51,范围:0.30-0.68)增加到4周(0.99,0.85-1.60),而经阴道分娩则没有变化:结论:高超的微血管成像技术能有效测量剖宫产切口部位子宫肌层微血管的血流恢复情况,显示了其作为产后伤口愈合监测工具的潜力。

Superb microvascular imaging for assessment of post-cesarean myometrial blood flow from 1 to 4 weeks after operation: A preliminary study.

Purpose: To evaluate superb microvascular imaging for measuring puerperal myometrial microvascular blood flows at incisional sites following cesarean delivery.

Methods: Twenty postpartum women (singleton births) were studied: 10 with cesarean and 10 with transvaginal deliveries. All cesarean cases were first operational delivery with lower uterine incision, repaired with double-layer suture. At 1 and 4 weeks postpartum, the uterus was delineated using transvaginal ultrasonography with superb microvascular imaging. Separate regions of interest were created for anterior myometrium of the isthmus and the body. The microvascular flow profile in three circular sampling points placed in a region of interest was quantified and expressed as vascular density. The vascular density ratio of the uterine isthmus to the body was compared between one and four weeks for both groups. Wilcoxon's signed-rank test was used to assess statistical significance (set at p < 0.05).

Results: In cesarean deliveries, the vascular density ratio of the uterine isthmus to the body increased from 1 (median: 0.51, range: 0.30-0.68) to 4 weeks (0.99, 0.85-1.60), whereas no changes were noted in transvaginal deliveries.

Conclusion: Superb microvascular imaging can effectively measure myometrial microvascular blood flow recovery at cesarean incision sites, indicating its potential as a tool for monitoring postpartum wound healing.

期刊介绍: The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography. The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents. JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
