Clinical imaging analysis of 12 cases of orbital solitary fibrous tumor / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM:To investigate the characteristics of color Doppler sonography and MRI in orbital solitary fibrous tumor(SFT). <p>METHODS: It was a retrospective case series study. A total of 12 cases of orbital solitary fibrous tumors were recruited from April 2013 to August 2018 in Tianjin Medical University Eye Hospital. Color Doppler sonography and MRI plain scan and DCE-MRI were applied in all cases. <p>RESULTS: Of 12 cases, 7 cases were males and 5 were females, with the duration of symptoms ranged from 3mo-20y, with an average course of 3.2y; 6 cases were the primary cases and 6 cases were relapse cases. All lesions involved one side of the orbit, of which 8 cases were in the left orbit and 4 in the right. Of 12 cases, there were 5 tumors in intraconal space, 3 in the extraconal space, and 4 in intra and extraconal space. Well-circumscribed lesions showed oval shape in 9 cases and the left 3 were irregular. 12 cases showed hypoechoic and 2 cases heterogeneous signal on color Doppler sonography; All cases had flow signals on CDFI, and showed arterial spectrum on PW. On T1WI, all lesions demonstrated isointense. On T2WI, 5 lesions showed hypointense, 3 lesions showed isointense and 4 lesions slight hyperintense, of which 3 lesions showed heterogeneous signal. After contrast enhancement, all cases demonstrated markedly enhancement, with homogeneous enhancement in 10 cases and heterogeneous enhancement in 2 cases. The time-intensity curves(TIC)of 7 cases exhibited a rapid washout pattern, and 5 cases a rapid plateau pattern on DCE-MRI. <p>CONCLUSION: Color Doppler sonography features of orbital SFT include hypoechoic and flow signals. Heterogeneous signals on T2WI, marked enhancement, and a rapidly enhancing and slow washout pattern TIC on DCE-MRI are the typical MRI features of orbital SFT.

Correlation of grayscale combined with color doppler sonography from histopathology in predicting retained products of conception / Philippine Journal of Obstetrics and Gynecology

Background@#Retained products of conception can be troublesome complications following miscarriages. Ultrasound has a significant impact in their diagnosis and with the advent of color doppler sonography can improve the assessment. @*Objective@#The goal of this study was to evaluate the use of grayscale combined with color Doppler ultrasound findings and correlate with histopathology in predicting retained products of conception in a maternity hospital. @*Methods@#This was a cross sectional prospective study of 109 patients who underwent transvaginal grayscale ultrasound with color Doppler to evaluate the presence of retained products of conception. Resistance index(RI) is measured in Pulsed doppler to assess the impedance of blood flow. The standard criterion was the histopathologic reports obtained during completion curettage. @*Results@#Histopathologic results validated the presence of immature placental tissues in 93 (85%) patients and decidua in 16 (15%). Endometrial mass was greater with positive histopath results (p<0.05). Endometrial mass had a sensitivity of 83.9% in detecting retained products of conception. Thickened endometrium was detected in 71.4 % of women with positive histopath results, but only in 28.6% with negative histopath results. Color flow was confirmed in 85% with positive histopathology results. @*Conclusion@#The combination of an endometrial mass with vascular pattern had the highest positive predictive value in determining retained products of conception.

The reevaluation and surgical strategy of the superficial circumflex iliac artery perforator (SCIP) flap / 中华显微外科杂志

Objective To introduce the classification of the perforators of the superficial circumflex iliac artery(SCIA),and the superficial circumflex iliac artery perforator (SCIP) flaps based on different perforators have different characters and harvesting methods.To explore a set of coping strategy for the drawbacks of the SCIP flap.Methods Review 90 cases of SCIP flaps in August,2011 to June,2017.The pre-operative radiology navigation was conducted in all cases.Different surgical approaches were applied in flaps based on different perforators.The pedicle elongation method was adopted when necessary.The thickness of the flap,the length of the pedicle,the survival rate of the flap and the closure of the donor site were analyzed.Regular follow-up was performed after the operation.Results All flaps were followed-up for 6-15 months (average 8 months).Fifty-seven flaps were raised on the basis of the proximal perforators of the superficial branch of the SCIA,whereas 29 cases were based on the distal perforators from the deep branch,and in 4 cases,the pedicle was switched to the superficial inferior epigastric artery.In 8 cases,the arterial pedicle lengthen technique was applied with a maximum length of 10 cm.All donor sites were closed directly.Conclusion These surgical strategies simplified the intraoperative decision-making and conquered the shortcomings of the SCIP flap.It is believed that the SCIP flap can possibly become the new workhorse flap in the field of reconstructive surgery.

Effects of induced endometritis on uterine blood flow in cows as evaluated by transrectal Doppler sonography

This study was conducted to evaluate the effects of induced endometritis on uterine blood flow in cows. Transrectal Doppler sonography was performed on uterine arteries of six cyclic cows before and for 4 days after inducing acute endometritis by intrauterine infusion of 720 mg of policresulen, and for 4 days of the following estrous cycle. Time-averaged maximum velocity (TAMV) increased (p 0.05) in the next 4 days of the same cycle. TAMV and PI values in the subsequent cycle did not differ (p > 0.05) from the values measured before infusion and showed no changes (p > 0.05) within the cycle. Blood flow parameters were not related (p > 0.05) to plasma concentrations of progesterone and estrogen. All cows showed an acute endometritis determined by histopathological findings of biopsy samples taken 1 day after infusion and fibrotic endometrial alterations detected in the subsequent cycle. No relationships were observed between fibrotic changes of the endometrium and uterine blood flow during either cycle. In conclusion, acute inflammation is accompanied by a rise in uterine blood flow, but fibrotic alterations do not seem to be related to Doppler sonographic findings.

Objective To explore the treatment of complications associated with non-functioning renal allografts using embolism of renal artery.Methods Six patients with non-functioning renal allografts were treated with renal artery embolism,morphous,blood flow of allografts and symptoms were observed.Results Hematuria disappeared in 3 days after embolism;blood pressure levels controlled by drugs were in a normal region.Using color Doppler sonography,we found no blood flow in 4 cases,discontinuous blood flow in 2 cases.Blood flow disappeared in all 6 allografts 3 months later,and the allografts had atrophied.Conclusion Embolism of renal artery may be an effective and safe method for the treatment of complications associated with non-functioning renal allografts,especially for some severe patients;it could avoid the risks of operation.

Evaluation of effects of uterine artery embolization for uterine fibroid by color Doppler sonography / 中国微创外科杂志

Objective To assess the clinical value of color doppler sonography in the evaluation of effects of uterine artery embolization(UAE) for the treatment of uterine fibroid.Methods Twentythree patients with symptomatic uterine fibroid were given transvaginal color Doppler sonography before and 1~7 days,1~3 months and 6~12 months after the UAE.Measurements of the uterus,myomas,and resistance index(RI) of the uterine artery were obtained. Results Out of 21 patients examined at 1~7 days after UAE,the uterus volume increased by a mean of 10% in 7 patients(4%~63%) and decreased by a mean of 21% in 14 patients(1%~67%) with the dominant myoma decreased by 24% in size(1%~56%).In 21 patients examined at 1~3 months after embolization,the uterus and dominant myoma decreased in size by 53%(24%~82%) and 47%(6%~88%),respectively.In 19 patients examined at 6~12 months,the uterus and myoma decreased in size by 66%(5%~91%) and 71%(32%~99%),respectively.Vessels inside and surrounding the myoma remarkably diminished or completely disappeared after embolization.No statistically significant changes in uterine artery RI were noted before and after UAE(F=0.47,P=0.70).Symptomatic improvements were achieved in 87% of patients(20/23) at 1 year after UAE. Conclusions UAE for the treatment of symptomatic uterine fibroid is safe and effective.Color Doppler sonography can evaluate the effect of UAE by means of measuring the volume of the uterus and myoma and the hemodynamic changes of the uterine artery before and after embolization.

Sonographic Findings of Endometrial Polyps / 대한산부인과학회지

OBJECTIVE: To characterize the sonographic findings of endometrial polyp and to differentiate it from other endometrial lesions. METHODS: Using transvaginal sonography, preoperative sonographic findings of pathologically proven endometrial polyp in 24 patients were retrospectively evaluated for the size, margin, echogenicity, nature (cystic, solid, mixed), and blood flow signal by color Doppler sonography (CDS). The t-test was used to check the statistical significance for Resistive index (RI) between endometrial polyp and other endometrial lesions. RESULTS: Of 110 patients studied for abnormal vaginal bleeding, 24 (21.9%) patients had endometrial polyps, 4 (3.6%) patients had secretory phased endometriums, 4 (3.6%) patients had submucosal myomas, 4 (3.6%) had retained placentaes, 1 (0.9%) had endometrial hyperplasia, 1 (0.9%) had blood clot, 1 (0.9%) had endometrial carcinoma and 71 (64.6%) patients had normal findings. The sonographic findings of endometrial polyp were well defined (24 patients), round (16 patients), hyperechoic (20 patients), and solid mass (21 patients). Using transvaginal CDS, the location of blood flow (9 patients) showed a single feeding artery with a mean RI of 0.60. There were no statistical significant differences between endometrial polyp and other endometrial lesions in arterial waveform (mean RI: 0.6) by transvaginal CDS (p>0.05). CONCLUSION: Endometrial polyp has a characteristic sonographic appearance of a well-defined, hyperechoic round mass by transvaginal sonography. In addition, it contains a single feeding vessel to the vascular stalk with a characteristic color Doppler signal detected by transvaginal CDS. These findings enable us to make differential diagnosis from other endometrial lesions.

Objective: To explore the value of combined treatment of advanced hepatic carcinoma. Methods:117 cases with advanced hepatic carcinoma underwent a combined treatment by radio frequency ablation(RF),percutaneous ethanol injecton(PEI),transcatheter hepatic arterial chemoembolization(TACE)and transultrasonic portal vein chemoembolization (SPVE).The comparison was made between this treatment and that of TACE alone in terms of size of tumor ,changes of blood supply and clinical effects before and after each of these two treatments. Results: After three months,Ultrasonographic examination showed that the tumor size decreased by 25.0% was 87.2%.The disappearing rate and decreasing rate of blood supply of tumor was 88.0%; AFP turning-negative rate was 78.3%.The follow-up survey showed that one-year and two-year survival rates for combined therapy were 73.5%and 62.4% respectively ,significantly higher than that for the control TACE group 59.4%and 32.6%. Conclusion: The combined treatments are effective ways for carcinoma treatment. Color Doppler imaging is important to guide and assess the treatment.

Role of Color Doppler Sonography in Transrectal Ultrasound Guided Biopsy of Prostate / 대한비뇨기과학회지

PURPOSE: The aim of this study is to correlate the findings at prostate CDS (Color doppler sonography) with those of site specific transrectal ultrasound (TRUS) guided biopsy for determining the role of CDS in detection of prostate cancer. MATERIALS AND METHODS: Forty-nine patients underwent TRUS guided biopsy because of palpable hard nodule of prostate, abnormal prostate specific antigen, or hypoechoic lesion of TRUS. CDS was performed at all biopsy sites before TRUS guided biopsy. Color flow at CDS was prospectively graded on a scale of 0, I, II (0=no or minimal, I=moderate, II=markedly increased color flow at peripheral zone). CDS results were correlated with histologic findings from 491 separate biopsy sites of 49 patients. RESULTS: Cancer was found on biopsy in 153 sites, prostatitis was found in 95 sites, and benign prostatic hyperplasia (BPH) was found in 243 sites. CDS had a sensitivity of 30.1%, specificity of 98.2%, positive predictive value of 88.5%, and negative predictive value of 75.6%. Of 52 grade II color flow biopsy sites, 46 were prostate cancer, prostatitis and BPH were 3 each other. Of 153 biopsy sites in prostate cancer, 46 sites were grade II, 62 sites were grade I, 45 sites were grade 0 color flow. CDS depicted cancer in 43 sites of 5 patients without gray scale abnormality. Of 16 patients with hypoechoic lesion, eight patients had cancer, but CDS did not assist to differentiate the cancer from benign lesion. CONCLUSIONS: Grade II color flow in peripheral zone is highly associated with prostate cancer. In case of no gray scale abnormality, CDS may help identify appropriate sites for biopsy. But, negative CDS do not exclude biopsy because of low sensitivity.

Diagnostic Efficacy of the Morphological Scoring System of Ultrasound, CA-125, Color Doppler Sonography(CDS), and Magnetic Resonance Imaging(MRI) in Detecting Ovarian Malignancy / 대한산부인과학회잡지

OBJECTIVE: Ovarian cancer is a silent disease with few symptoms. Because early detection of ovarian cancer is difficult, most cases are diagnosed at an advanced stage. To determine whether an ovarian tumor is malignant or not, various diagnostic procedures have been used including physical examination, ultrasound and tumor markers such as CA-125. We recently compared color Doppler sonography(CDS) with the morphological scoring system and CA-125 levels in establishing an accurate preoperative diagnosis of adnexal mass. As a result, we tried to compare the morphological scoring system with CA-125 and CDS in the diagnosis of adnexal mass. METHODS: The medical records of 47 patients referred with preexisting adnexal lesion were reviewed retrospectively by comparing ultrasonic data(morphological scoring system and color Doppler finding) with serum CA-125 and MRI findings. RESULTS: Forty-nine masses were removed surgically and confirmed as 25 malignancies and 22 benign tumors. In cases using the morphological scoring system and CA-125, the accuracy showed 95% sensitivity. In cases using the morphological scoring system and CDS, the sensitivity was 88%. In cases using the morphological scoring system and CDS, the sensitivity was 48%. CONCLUSIONS: The morphological scoring system and CA-125 are the basic methods for predicting ovarian malignancy. MRI and CDS may be also useful diagnosis methods in diagnosis of ovarian malignancy. But combination of these diagnositic modalities may not improve the accuracy of predicting ovarian malignancy, significantly.

Clinical value of monitoring blood flow of transplanted kidney by color Doppler sonography / 中华器官移植杂志

Retrospective analysis of 761 case-times successive color Doppler sonography for 518 renal transplant patients was carried out.six parameters of sonography were used to compare, the CsA-NT hemodynamic changes among the patients with normal function, rejected and hy-dronephrotic kidney.It revealed that during rejection of the rendl srafts, besides an elevation of resistance index(RI)and a decrease of D/S ratio, the velocity and volume of renal blood flow were also slowed down and decreased respectively.After combating rejection, the renal function recovered to normal gradually, and RI dropped below 0.75 subsequently.Otherwise R1 would be persistently elevated, which indicated an irreversible rejection.The diagnosis of acute rejection was given at RI≥0.83, with the sensitivity rate being 82.70%and specificity being 80.10%.It was suggested that RI is a relatively sensitive and relialble parameter for the diagnosis of rejection.In combination with the clinical manifestations RI is of great important clinical value for the early diagnosis and treatment of acute rejection.

Post-Biopsy Arterio-Venous Fistula: Color Doppler Sonography in Evaluation of Its Incidence and Evolution / 대한신장학회잡지

Arteriovenous fistulae(AVF) are well documented complications of percutaneous renal biopsy. Between August 1995 and April 1997, we prospectively studied 280 consecutive ultransound-guided percutaneous renal biopsies to evaluate the incidence of post-biopsy AVF and its natural course. All biopsies patients were monitored through a routine follow-up echo-color popple sonography at post-biopsy 1, 7, 14 and 30 days. The 28 patients(10%) out of 280 consecutive percutaneous renal biopses were diagnosed to have AVF. There was no differences in the incidence of AVF between native and transplanted kidney biopsy. Most AVF were small(<2cm) and caused minimal or no symptoms. AVF was accompanied with large hematoma(thickness above 2cm) was observed in 9 cases(53%) of 17 native kidneys and none in 10 transplanted kidneys. This difference was statistically significant(P=0.008). At follow-up, AVF resolved spontaneously in 24 cases(87%). In two patients(7.1%) required superselective arterial embolization, one develoved spontaneous rupture of AVF, and one had persistence of AVF over 12 months. We concluded that color Doppler sonography provides a good, non-invasive and safe method for diagnosis and follow up of post-biopsy AVF.
