Transvaginal power Doppler ultrasound in pelvic congestion

Purpose: 
Pelvic congestion is diagnosed by transuterine venography, an invasive procedure requiring sedation and irradiation. Ultrasound may be an alternative but is hindered by slow flow within pelvic veins. In an attempt to counter this, we investigated the possible role of transvaginal power Doppler ultrasound. Material and Methods: 
42 women with a clinical suspicion of pelvic congestion underwent transvaginal ultrasound. Adnexal veins were examined and a congestion score established. Planimetric measurements of adnexal vessels were obtained using power Doppler ultrasound, and uterine and ovarian morphology noted. All women then underwent transuterine venography and agreement with the ultrasound congestion score and morphologic features was determined. Results: 
There was a trend towards weak positive correlation between ultrasound and venography congestion scores (r = 0.29, p = 0.06). However, agreement between scores was poor on an individual basis (95% limits of agreement, -3.9 to +2.7). Planimetric power Doppler assessments of adnexal vascularity were unrelated to venographic congestion. Instead, there was correlation between the number and diameter of ovarian follicles and venographic congestion: women with congestion tended to have significantly more (0.04) and smaller follicles (p = 0.001). Conclusion: 
There was poor individual agreement between ultrasound and venographic estimates of congestion. However, there was a direct relationship between venographic congestion score and ovarian morphology.     

Prevalence of abnormal CT findings in patients with proven ovarian torsion and a proposed triage schema

Many women with ovarian torsion present with nonspecific abdominal/pelvic pain and initially receive computed tomography (CT). We hypothesize that the CT scans preformed on these women will all show abnormalities of the involved ovary. Our purpose is to review cases of surgically proven ovarian torsion at our institution over the last 20 years, assessing CT findings in women with ovarian torsion. A retrospective review of all patients at our institution with surgically proven ovarian torsion from 1985–2005 was conducted. Two physicians reviewed available CT reports, and a radiologist reviewed all available images. CT was obtained in 33% of the 167 patients. Dictated reports were available for 28 studies; all described an enlarged ovary, ovarian cyst, or adnexal mass of the involved ovary. Radiologist review of the available CT images confirmed these findings. This series supports the claim that a CT scan with well-visualized normal appearing ovaries rules out ovarian torsion, while abnormal pelvic findings or failure to visualize the ovaries in women with pelvic pain necessitates further evaluation of torsion. There was no extramural support for this investigation.     

Diagnosis of pelvic congestion syndrome using transabdominal and transvaginal sonography

OBJECTIVE: We prospectively evaluated transabdominal and transvaginal sonographic findings of patients with pelvic congestion syndrome and compared them with those of healthy volunteers. SUBJECTS AND METHODS. We examined 32 patients with pelvic congestion syndrome and 35 control subjects. Using transabdominal sonography, we evaluated the ovarian veins for diameter and flow direction, presence of pelvic varicocele, diameter of the pelvic veins, change of the duplex waveform during the Valsalva's maneuver, volume of the uterus, and presence of polycystic changes in the ovaries. We compared and statistically analyzed each parameter in the pelvic congestion syndrome group and in the control group. RESULTS: The mean (+/- SD) diameter of the left ovarian vein was 0.79 +/- 0.23 cm in the pelvic congestion syndrome group and 0.49 +/- 0.15 cm in the control group (p = 0.000). Reversed caudal flow in the left ovarian vein was present in 22 of 22 patients and in four of 16 control subjects. Pelvic varicoceles were present in all patients with pelvic congestion syndrome and in six control subjects. The mean diameter of the left pelvic vein was 0.68 +/- 0.21 cm in the pelvic congestion syndrome group and 0.42 +/- 0.19 cm in the control group; the mean diameter of the right pelvic vein was 0.64 +/- 0.24 cm in the pelvic congestion syndrome group and 0.35 +/- 0.14 cm in the control group (p = 0.000). Polycystic changes of the ovary were present in 13 patients with pelvic congestion syndrome (40.6%) and four control subjects (11.4%). CONCLUSION: Sonographic findings of pelvic congestion syndrome were dilated left ovarian vein with reversed caudal flow, presence of varicocele, dilated arcuate veins crossing the uterine myometrium, polycystic changes of the ovary, and variable duplex waveform during the Valsalva's maneuver. Combined transabdominal and transvaginal sonography are potentially useful as a noninvasive screening tool for determining which patients with chronic pelvic pain may benefit from selective ovarian venography and transcatheter embolization.     

The role of transvaginal ultrasound in the assessment of the female pelvis

Transabdominal ultrasound of the female pelvis has been compared with transvaginal ultrasound, using a 7.5 MHz transducer, in 80 women. Transvaginal ultrasound required less patient time and was preferred in 56% of patients. Image quality was superior in 72% of cases, and visualisation of the pelvic organs was equivalent with each technique. Transabdominal ultrasound gives a more global view of the pelvis, and is of more value in assessing large pelvic masses. Transvaginal ultrasound is of more value in assessing early pregnancy, ectopic pregnancy, ovarian abnormalities, and for visualising the ovaries following hysterectomy.     

Double retroaortic left renal veins as a possible cause of pelvic congestion syndrome: imaging findings in two patients

Pelvic congestion syndrome is characterized by chronic pelvic pain and varicose veins around the uterus and ovaries. We report two cases of double retroaortic left renal vein, associated with left-sided pelvic congestion syndrome, diagnosed by CT and confirmed by clinical findings and colour Doppler ultrasound. Double retroaortic left renal veins may be a contributing factor for the development of left pelvic congestion syndrome. This is the first report of double retroaortic left renal vein and associated pelvic congestion syndrome.     

Treatment of Symptomatic High-Flow Female Varicoceles with Stop-flow Foam Sclerotherapy

Purpose

To assess the efficacy of stop-flow foam sclerotherapy (SFFS) in high-flow pelvic varicoceles using 3 % sodium tetradecyl sulfate (STS) foam.

Methods

Our institutional review board granted approval and waived informed consent for this retrospective study of 26 patients (mean age 37.3 years, range 23–46 years) with pelvic congestion syndrome (PCS) who had high-outflow venous collaterals treated by SFFS between June 2005 and June 2011 in our department. PCS was diagnosed by physical and transvaginal color Doppler ultrasound examination, while high-outflow venous collaterals were detected at selective ovarian venography. SFFS was performed by injection of 3 % STS foam into the pelvic varices after balloon occlusion of the major venous vessels (hypogastric and/or ovarian veins) to which the high-outflow venous collaterals were tributary. Follow-up was performed at 1, 3, 6, and 12 months by physical and transvaginal color Doppler ultrasound examination and by a questionnaire-based assessment of pain using a symptom severity score.

Results

The procedure was technically successful in all patients. After the injection of 3 % STS foam, all patients had a colic like pain that spontaneously resolved after 5 min. During follow-up, no recurrences of PCS were detected. Significant improvement of symptoms (Student’s t test P < 0.01) was observed at 1, 3, 6, and 12 months.

Conclusion

SFFS using 3 % STS foam is a safe and effective treatment for high-flow female varicoceles and should be considered as an alternative to other endovascular and surgical options.     

Pelvic congestion in women: evaluation with transvaginal ultrasound and observation of venous pharmacology

Fourteen women with chronic pelvic pain due to congestion underwent transvaginal ultrasound scanning to observe changes in the diameters of dilated pelvic veins. Spontaneous fluctuations were observed, and intravenous dihydroergotamine resulted in a consistent venoconstrictor response (p = 0.0021) during 20 min observation. Transvaginal ultrasound is useful for imaging dilated pelvic veins and for the study of venous pharmacology.     

Gynecologic ultrasound

For most women, pelvic sonography using a transvaginal probe is the imaging modality of choice for evaluating the uterus and adnexae. It is reliable for detecting ovarian cysts and other adnexal masses, and it can often determine if a lesion can be observed on serial examinations or if it requires more urgent attention. Uterine ultrasound is reliable for evaluating both the normal and abnormal endometrium and myometrium. In cases that are technically limited, or in those that are difficult to interpret, a tailored MR imaging examination often can be helpful.     

Scintigraphic localization of ovarian dysfunction

To assess the potential role of scintigraphy in the evaluation of clinically and biochemically suspect ovarian hyperandrogenism (HA), dexamethasone suppression 131I-6 beta-iodomethyl-19-norcholesterol (NP-59) scans were performed to characterize ovarian function in nine patients. Pelvic ultrasound and/or computed tomography (CT) identified anatomic abnormalities in the adnexal region in six women in whom there was discernible pelvic accumulation(s) of NP-59. In the remaining three patients testosterone levels were normal or only slightly elevated and the NP-59 scan did not demonstrate abnormal adrenal or pelvic uptake. CT and/or ultrasound studies failed to demonstrate an abnormality in the pelvis suggesting excessive peripheral conversion or abnormal end organ sensitivity of androgen precursors as potential etiologies of their HA. In three women with androgen secreting lipoid tumors of the ovary, unilateral, pelvic NP-59 activity was noted; these tumors were subsequently resected. Two women with bilateral pelvic NP-59 uptake were later shown to have hyperthecosis with markedly asymmetric and enlarged ovaries. In one woman the extent of asymmetric NP-59 uptake was anticipated by the asymmetry of ovarian vein androgen levels at selective venous catheterization. In another woman with markedly asymmetric polycystic ovary disease, intense focal uptake of NP-59 localized to the side of the anatomically abnormal, enlarged ovary. Thus, our preliminary study reviews our experience to date and suggests that NP-59 scintigraphy may be used to localize both tumorous and nontumorous ovarian dysfunction in states of HA and virilization.

Recovery of ovarian function after detorsion: Doppler findings

Adnexal torsion is one of the most common surgical gynecologic emergencies and needs prompt diagnosis. It usually occurs during reproductive age, which makes the early diagnosis all the more important in attempting to preserve ovarian function. If adnexal torsion is suspected from the clinical findings, Doppler ultrasound can be the best tool in diagnosis. It can also be helpful in assessing recovery of the ovary after surgical treatment. We present a case of adnexal torsion successfully diagnosed with power Doppler ultrasound and managed by detorsion. The postoperative gray-scale and power Doppler examination confirmed the recovery of ovarian follicles and stoma.     

Trans-catheter ovarian vein coiling in management of symptomatic females having chronic pelvic congestion

Transvaginal US-guided aspiration of ovarian cysts and solid pelvic masses.

Sixty-eight transvaginal ultrasound (US)-guided aspirations or biopsies were performed in 61 patients, of whom 48 had ovarian cysts and 13 had solid pelvic masses. In one patient with an ovarian cyst, aspiration revealed malignancy. Thirty-six of the 48 cysts were drained transvaginally in 23 premenopausal and 13 postmenopausal women, with recurrence rates of 48% and 80%, respectively. In seven cases a cyst was aspirated twice. In the 13 patients with solid pelvic lesions, 11 lesions proved to be malignant, with positive biopsy results in nine (sensitivity, 82%). Two benign lesions were correctly identified. No major complication was observed. The authors conclude that the transvaginal route offers simple access to pelvic lesions in pre- and postmenopausal patients. For women with a solid pelvic lesion, transvaginal aspiration biopsy with endovaginal US guidance is a safe and effective alternative to surgery, especially for patients with previously diagnosed malignant disease.     

Percutaneous treatment of pelvic congestion syndrome

INTRODUCTION: Pelvic congestion syndrome and chronic pelvic pain are enigmatic clinical conditions that may have considerable impact on the social and relational life of women. Patients usually complain of lower abdominal pain that has lasted for more than six months, is intermittent or continuous, and may become worse during menses or after a hard day's work. Sometimes the pain is accompanied by dyspareunia, urinary urgency or constipation. The traditional treatment of pelvic congestion syndrome has included both medical (analgesics, hormones) and surgical approaches (hysterectomy, ovarian vein ligation). Recently, percutaneous transcatheter embolization has also been proposed. We report our experience with the percutaneous management of pelvic congestion syndrome, using the transbrachial approach and sclerosis alone. MATERIAL AND METHODS: Between 1996 and 2001, 33 women underwent percutaneous treatment for pelvic congestion syndrome at our department. All the women had chronic pelvic pain which was continuous in 69%; 20 patients had dyspareunia, whereas 8 had urinary urgency; 72% took analgesics on a regular basis. All the patients underwent percutaneous treatment of pelvic congestion syndrome on a outpatient basis in a radiological suite, after receiving local anaesthesia. Sclerosis was performed with 3% sodium tetradecyl sulfate. Follow-up consisted of a questionnaire at one month and gynaecological and ultrasound examinations at 6/12 months. RESULTS: The pre-procedural ultrasound examination had revealed a mean diameter of 4.5 mm for the right ovarian vein and of 6.3 mm for the left. We found one pelvic congestion syndrome on the right, 11 on the left and 21 bilaterally. At the one-month follow-up, chronic pelvic pain was present in 13 patients (39%); the pain was continuous in three and intermittent in ten. At the follow-up after 6/12 months the symptoms were unchanged. Ultrasound revealed a reduction in periovarian varicosities, recording a mean diameter of 3.19 mm on the right and 4.5 mm on the left. Symptoms persisted in women with pelvic varicosities measuring over 5 mm at ultrasound. CONCLUSIONS: Pelvic congestion syndrome and chronic pelvic pain that do not respond to medical therapy can be resolved by percutaneous management. Less expensive than surgery, this therapeutic option is safe, effective, minimally invasive and capable of restoring patients to normal function. We propose the transbrachial approach as the first-choice treatment for bilateral pelvic congestion syndrome.     

Transcatheter Foam Sclerotherapy of Symptomatic Female Varicocele with Sodium-Tetradecyl-Sulfate Foam

To evaluate the efficacy of transcatheter foam sclerotherapy (TCFS) in pelvic varicocele using sodium-tetradecyl-sulfate foam (STSF), we conducted a retrospective study in 38 patients (mean age, 36.9 years; range, 22–44 years) with pelvic congestion syndrome (PCS) treated between January 2000 and June 2005 by TCFS. Pelvic pain was associated with dyspareunia in 23 (60.5%) patients, urinary urgency in 9 (23.7%) patients, and worsening of pain during menstruation and at the end of a day of work in 7 (18.4%) and 38 (100%) patients, respectively. Diagnosis was made by pelvic and transvaginal color Doppler ultrasound examination, demonstrating ovarian or pelvic varices with a diameter >5 mm presenting venous reflux. TCFS was performed in all patients, using 3% STSF. Follow-up was performed by physical examination, pelvic and transvaginal Doppler ultrasound examination and by a questionnaire-based assessment of pain at 1, 3, 6, and 12 months after the procedure. Technical success was achieved in all patients (100%). In three patients a pelvic colic-like pain occurred immediately after sclerotic agent injection, disappearing spontaneously after a few minutes. No recurrent varicoceles were observed during a 12-month follow-up. A statistically significant improvement in each category of specific symptoms was observed at 1, 3, 6, and 12 months after the procedure. We conclude that TCFS of female varicocele using a 3% STSF is safe and effective for the treatment of PCS. It is associated with a significant reduction of symptoms and can be regarded as a valid alternative to other endovascular and surgical techniques.

Ultrasound and MR imaging of diabetic mastopathy

AIM: To review the imaging findings of diabetic mastopathy, and document the colour flow ultrasound and MR imaging features in this benign condition. MATERIALS AND METHODS: Diabetic mastopathy was clinically and histologically diagnosed in eight lesions in six women. All six women underwent conventional mammography and high frequency grey-scale ultrasound. Colour flow ultrasound was performed additionally in six lesions in four women and MR imaging in four lesions in three women before biopsy. The imaging findings were reviewed and correlated with final histological diagnosis. RESULTS: Mammography showed regional asymmetric increased opacity with ill-defined margins in all lesions. A heterogeneously hypoechoic mass with ill-defined margins was identified on high frequency grey-scale ultrasound in all lesions. Marked posterior acoustic shadowing was present in seven of eight (88%) lesions. Six lesions interrogated with colour flow ultrasound showed absence of Doppler signal. MR imaging in three women revealed non-specific stromal enhancement. CONCLUSION: Diabetic mastopathy shows absence of Doppler signal on colour flow ultrasound and non-specific stromal enhancement on MR imaging.     

Evaluation of Effectiveness of Embolization in Pelvic Congestion Syndrome with the New Vascular Occlusion Device (ArtVentive EOS™): Preliminary Results

Purpose

This study aimed to collect confirmatory data in support of the safety and efficiency of the ArtVentive EOS? for the treatment of the pelvic congestion syndrome (PCS). This study was based on the OCCLUDE 1 Study Protocol approved by the Local Ethics Committee.

Materials and Methods

A prospective study carried out in June and July 2014 included 12 women aged 21–48 years (mean 31 years) scheduled for PCS embolization using the ArtVentive EOS?. The inclusion criteria were clinical symptoms of PCS documented by transvaginal Doppler ultrasound and pelvic MRI. The pelvic pain was assessed by VAS score from 0 to 10 (0 represents lack of pain and 10 unbearable pain). A decrease in pelvic pain intensity based on the VAS was considered a clinical success.

Results

Successful embolization procedures with ArtVentive EOS? were performed in 11 out of 12 patients. Nine patients underwent unilateral embolization of the left ovarian vein, and two had bilateral embolization of the ovarian veins. Complete ovarian vein occlusion confirmed by post deployment venography was achieved in all 11 patients. Procedures lasted from 19 to 45 min (average 28 min). Pain intensity decrease was observed in all 11 patients—a decrease of 5.6 points—from 7.3 pre-procedure to 1.6 post-embolization (standard deviation: 0.67). In one case, the left ovarian vein was injured by guide wire manipulation with contrast extravasation—not clinically significant.

Conclusions

The use of ArtVentive EOS? for occlusion of the ovarian veins in PCS patients is safe and effective.

     

Case report: the ultrasound and Doppler appearances of pelvic varices

Dilatation of the veins of the broad ligament and ovarian plexi cause a very specific clinical entity called the pelvic congestion or pelvic pain syndrome. The ultrasound and Doppler appearances of this condition are unique and should be easily recognized. We describe these appearances in one patient and review the literature.
