Objective To analyze the color Doppler flow imaging (CDFI) in 12 cases of induced abortion post-operative uterine cavity caused by traumatic arteriovenous fistula color blood flow signal and frequency spectrum characteristics. Methods Application of color Doppler ultrasonic diagnostic instrument, screening from January 2009 to June 2014 line appears irregular vaginal bleeding after abortion or sudden hemorrhage patients of our hospital, with color Doppler ultrasound examination, uterine cavity is unusually rich blood flow mass in 12 cases color and spectral Doppler blood flow condition analysis. Results Eight cases of postoperative uterine arteriovenous fistula induced abortion color Doppler were showed the zone of intrauterine lesions showed colorful Mosaic blood flow signal and doppler frequency spectrum performance for high speed frequency spectrum characteristics of low resistance, PSV 42-98 cm/s, was RI 0.28-0.45, and continuous venous blood flow spectrum measurement at the same time. Among them 9 cases for 2 weeks postoperatively, through successful anti-inflammatory hemostasia conservative treatment, 2 cases of postoperative 3 weeks, with intrauterine villi residue, lines and curettage after uterine artery embolization cured, 1 case for 6 weeks postoperatively, due to blood loss is bigger, line success after uterine artery embolization. Conclusion Postoper-ative uterine arteriovenous fistula is abortion cause vaginal bleeding of rare but serious complication of color Doppler ul-trasound in the diagnosis of uterine arteriovenous fistula to guide clinical therapy has a certain practical value.

甲状腺结节的临床发病率较高，尤其在碘充足地区，据统计有5%的女性和1%的男性存在可触及的甲状腺结节。另有数据显示经高分辨率超声检查，在随机选择人群中甲状腺结节的检出率为19%～67%。目前高频超声检查作为诊断甲状腺结节疾病的手段在临床上已普遍使用，既往超声检查主要依靠常规二维灰阶及彩色多普勒超声，对甲状腺良恶性结节的鉴别诊断价值有限。近10年来超声弹性成像是发展起来的一项新技术，有助于甲状腺良恶性结节的鉴别，但是目前的弹性成像技术多应用面积评分法和测定病灶与周围组织应变率比值法，均为半定量测定甲状腺结节硬度的方法。最新的实时剪切波弹性成像（shear wave elastography，SWE）为定量测量技术。 SEW技术能够实时、独立地测得组织杨氏模量，并且具有很好的重复性。可以直接、定量地反映甲状腺结节绝对硬度，为甲状腺结节良恶性鉴别提供了一个固有的、新的、有价值的、更为客观的诊断方法，具有广阔的临床应用前景。

患者男,48岁.醉酒嗜睡16 h后觉腹痛,腹胀,不能自主排尿来诊.患者小腹极度憋胀,以至不能平卧,遂置尿管导尿,导出血尿量约500 ml,腹痛腹胀症状有所缓解,行超声检查见:肝胆胰脾双肾未见异常,盆腔内少量积液,膀胱充盈不佳,膀胱腔内可见尿管声像,球囊位于膀胱右侧方,其周围未见明显膀胱壁(图1),超声诊断:盆腔积液,不除外膀胱破裂可能.

患者女,35岁.因月经周期缩短,经量增多5+月,排尿困难1个月,加重1 d就诊.超声检查示:子宫颈后唇肌瘤伴囊性变.为保留子宫,采取了经阴道摘除肌瘤手术.术后次日高热,经抗感染治疗无效.术后第4天阴道间断性排出黑绿色渣样物.超声检查示:左膈下局限条形液性暗区,子宫体左后方见不均质等回声及强回声混合性包块,无明显包膜,边界不清,后方伴声影(图1).CDFI:包块周围无血流信号显示,超声提示阴道直肠瘘可能.剖腹探查见直肠中段前壁约1.5 cm破口,漏黄色液体,周围粘连,附坏死组织.

患者,女性,34岁.因车祸伤1小时入院.查体:血压90/60 mmHg,脉搏128次/分,呼吸24次/分,神志不清,左顶枕部约15 cm×15 cm皮下血肿,双瞳孔正大等圆,直径0.6 cm,对光反射欠灵敏,面部散在皮擦伤,颈部稍抵抗,心肺(-),腹膨隆,腹肌紧张,移动性浊音(+),肠鸣音消失.头部CT报告:蛛网膜下腔出血.血常规:WBC 27.8×109/L,RBC3.04×109/L,HB 87 g/L.尿常规:肉眼血尿,红细胞充满视野,腰穿抽出少量不凝血.
