Pelvic congestion syndrome

Application of the Symptoms-Varices-Pathophysiology classification system in patients with pelvic venous disorders

Introduction: In 2021, the American Vein and Lymphatic Society convened a multi-disciplinary group to develop a valid and reliable discriminative instrument for the classification of patients suffering from pelvic venous disorders (PeVD) referred to as the Symptoms-Varices-Pathophysiology (SVP) system. Limited data exists regarding the utility of this instrument in the care of patients with PeVD. The goal of this investigation is to apply the SVP classification system to a group of patients treated for PeVDs. Methods: From January 2018 to January 2019, we retrospectively reviewed the records of 70 female patients treated for a PeVD at the Center for Vascular Medicine. Age, race, gender, medical/surgical histories, CEAP classification and intervention types were assessed and patients were categorized according to their SVP classification. The prevalence of each S and V class, their association with gonadal or iliac vein obstructive lesions and the prevalence of lower extremity varicosities was evaluated. Results: The average age of the entire cohort was 47.4 ± 13.4. The race distribution was as follows: African American (6), Hispanic (1), and Caucasian (63). Of the 140 limbs, 57% were C3 or greater with an average rVCSS score of 4.53. At the time of intervention, 54 patients (77%) demonstrated CEAP class 2 disease or greater with 25 patients (35%) demonstrating lower extremity varicosities. Medical co-morbidities included the following: Endometriosis (n = 1), Uterine Fibroids (n = 1), Ovarian cysts (n = 4), history of venous thrombosis (n = 2) and prior lower extremity venous procedures (n = 3). Overall, 47 patients (67.1%) demonstrated S2 disease secondary to dyspareunia, post-coital pain, or dysmenorrhea. S2 alone was observed in 17 patients (24.3%), S2,3a and S2,3a,3b in nine patients each (12.9%), and S2,3b was in 12 patients (17.1%). Thirteen patients presented with isolated extra-pelvic symptoms (19%); four (5.7%) were classified as S3a,3b, and nine (12.9%) were classified as S3b only. Finally, 10 patients (14%) had no pelvic symptoms and thus were classified as S0. V0 disease was observed in 17 patients (24.3%) secondary to a high incidence of iliac vein stenoses (IVS). V1 disease was observed in 1 patient (1.43%). V2 disease was observed in 53 patients (74.3%) secondary to iliac or ovarian vein reflux. Of these, 45 patients (64.3%) presented with reflux in the iliac veins. Sixteen patients had reflux in the common iliac veins, 17 patients exhibited reflux of the external iliac veins, and 41 patients demonstrated reflux of the internal iliac veins. Thirty-two patients (45.7%) presented with V2 disease secondary to reflux of the ovarian veins, 8 of whom presented with isolated ovarian vein reflux without IVS. Bilateral ovarian vein reflux was observed in 6 patients (9%) and unilaterally in 26 (37%) patients with concomitant ovarian vein reflux and IVS observed in 31 patients (44%). In patients with ovarian vein reflux, 89% had a concomitant iliac vein stenosis: (96.9% in the common iliac vein, 81.3% in the external iliac vein and 3.1% in the internal iliac vein). Conclusion: In our patient cohort, 70 women demonstrated 14 different SV classifications. The most common was S2V2, found in 10 patients. Chronic pelvic pain of venous origin, S2 disease, was the most common symptom, present in 47 patients (67.1%); followed by extra-pelvic symptoms as 22 patients demonstrated symptoms of the external genitalia (S3a), and 21 patients had symptoms secondary to the non-saphenous leg veins (S3b). Pelvic varicosities, V2, were also the most common variceal pattern seen in 53 patients, and 17 patients did not have any varices noted by venogram. Non-thrombotic IVS either alone or with ovarian vein reflux was the most common cause of PeVD in this cohort and may reflect referral patterns to our center. To determine the true incidence of these SVP patterns, larger cohort studies are necessary.

Relationships Among Pelvic Congestion Syndrome Pain, Daily Activities, and Quality of Life

OBJECTIVE

To examine women's experiences of pelvic congestion syndrome (PCS) pain.

DESIGN

Descriptive, cross-sectional.

SETTING

Online questionnaires in a Facebook PCS support group.

PARTICIPANTS

Convenience sample of 143 women who self-identified as being diagnosed with PCS.

METHODS

We recruited women through a social media support group and invited them to participate in a self-reported questionnaire. We collected demographic information and used the McGill Pain Questionnaire to elicit responses related to pain quality, pain intensity, quality of life, and satisfaction with health care. We analyzed data using descriptive statistics and correlation coefficients.

RESULTS

Respondents characterized their PCS pain as exhausting, stabbing, sharp, shooting, and tender. Respondents indicated that 19 of 24 daily activities increased PCS pain, whereas only 5 reduced PCS pain. Pain intensity was negatively related to the quality of life, health satisfaction, sleep, and sexual relationships.

CONCLUSION

Chronic pelvic pain from PCS severely affected quality of life among respondents. These findings suggest a difference in the presentation of PCS from historical pain depictions and further highlight the need to identify pain profiles to increase timely and precise diagnosis. Further research is needed to evaluate interventions to increase the quality of life for women with PCS.

Improvement in chronic pelvic pain, orthostatic intolerance and interstitial cystitis symptoms after treatment of pelvic vein insufficiency

OBJECTIVES

Comorbidities associated with venous origin chronic pelvic pain (VO-CPP) were evaluated pre and post venous treatment to assess change.

MATERIALS AND METHODS

45 women with VO-CPP were treated with venous stenting and/or embolization. Four surveys assessed symptoms pre- and post-treatment: IPPS (chronic pelvic pain), PUF (interstitial cystitis), OHQ (dysautonomia), and modified ROME III (IBS). Prevalence of joint hypermobility was investigated.

RESULTS

Ages were 18-65. Pretreatment, 64% and 49% of women were in the severe range for PUF and OHQ, respectively. 40% and 56% met criteria for IBS and Ehlers-Danlos syndrome/Hypermobility Spectrum Disorder (EDS/HSD), respectively. 17eceived an iliac stent, 5 pelvic embolization, and 23 both. Post-treatment, average scores improved: IPPS (by 55%), PUF (34%), and OHQ (49%). Rome III improved only slightly.

CONCLUSION

Pelvic pain, interstitial cystitis, and dysautonomia were frequently found with VO-CPP and improved after venous treatment. EDS/HSD and IBS were common in these women.

Successful Ovarian Vein Embolization of a Multiparous Woman with Pelvic Congestion Syndrome

Pelvic congestion syndrome (PCS) is a clinical syndrome supported by specific findings, such as ovarian vein's dilatation, that cause pelvic vein congestion. Although many theories are explaining the pathophysiologies of this condition, the underlying cause remains unknown. The clinical manifestations of PCS are various including chronic pelvic pain (CPP), voiding disturbances, or ureteral obstruction. Imaging modality, such as ultrasonography, computed tomography (CT scan), magnetic resonance imaging (MRI), and venography, are needed to confirm and exclude the differential diagnosis. Currently, American venous forum guidelines recommended endovascular therapy which is percutaneous embolization as the first option therapy of PCS. Here, we reported a 35-year-old woman with PCS who underwent successful percutaneous embolization therapy.

Balancing evidence-based care with patient-centered individualized care

Weak evidence, when manifested in clinical guidelines, can translate into biased vascular care. In vascular surgery, we have few randomized controlled trials with appropriate representation of females and persons of color, so generalizability of trial results can be problematic. Physicians are required to balance evidenced-based care (which is only as good as the underlying evidence) with personalized treatment recommendations that are often based on demographics, social circumstances, and/or existing therapeutic relationships. Biases, whether implicit or explicit, have an oversized effect on treatment decisions, and patient outcomes. In this commentary, we propose three principles to strengthen the vascular surgery evidence foundation and patient-centered decision-making going forward: (1) generating evidence designed for individualized care, (2) constructing clinical guidelines that are context specific and complexity aware, and (3) strengthening the training and support for surgeons to deliver patient-centered individualized care.

Transabdominal ultrasound accurately identifies a significant iliac vein area-reducing lesion in patients with pelvic venous insufficiency

BACKGROUND

In patients with pelvic venous disorders secondary to pelvic venous insufficiency (PVI), the optimal imaging modality is ill-defined. Transabdominal ultrasound (TAU) is widely used to identify the presence of iliac vein stenosis. The purpose of the present investigation is to determine the accuracy of TAU for determining the presence of an iliac vein area-reducing lesion compared with intravascular ultrasound (IVUS).

METHODS

From January to December 2020, a retrospective review of prospectively collected data from 96 patients treated for symptomatic PVI at the Center for Vascular Medicine was performed. All patients had complete history and physical examination findings, demographics, CEAP (clinical, etiologic, anatomic, pathophysiologic), revised venous clinical severity score, and TAU, diagnostic venography, and IVUS measurements recorded in our electronic medical record system. All TAU measurements were performed by the same ultrasound technician with the patient in the supine position. Iliac vein diameters of the common femoral, external iliac, and common iliac veins and the inferior vena cava were obtained. Differences in body habitus were normalized by dividing the minimum diameter measurement of the stenotic vessel with that of the ipsilateral common femoral vein, subtracting this number from 1 and multiplying by 100 (stenosis = [1 - minimal diameter/common femoral diameter] × 100). The normalized stenoses were then compared with the IVUS-derived area reducing measurements. A receiver operating characteristic curve was created, and logistic regression analysis for the probability of predicting an area-reducing lesion of >50% and >60% with TAU was performed. The sensitivity, specificity, and positive and negative predictive values were calculated.

RESULTS

The average age of the entire cohort was 49.8 ± 13.5 years, with 69 women and 27 men. The CEAP distribution was as follows: C0, 5%; C1, 5%; C2, 10%; C3, 40%; C4a,b, 30%; C5, 7%; and C6, 3%. The average revised venous clinical severity score was 6.2 ± 2.6. The indications for intervention were leg symptoms alone in 43%, pelvic symptoms alone in 3%, and combined leg and pelvic symptoms in 54%. TAU identified a stenosis of ≥50% in 92 of the 96 patients (96%). For a ≥50% stenosis, a normalized diameter of ≤3 mm demonstrated a sensitivity, specificity, and positive and negative predictive value of 75%, 75%, 98%, and 12%, respectively. Logistic regression analysis indicated that TAU was significant in predicting the presence of a ≥60% area-reducing lesion (odds ratio, 1.03; 95% confidence interval, 1.01-1.05; P = .009). The area under the receiver operating characteristic curve (c-statistic) was 68.6%. The sensitivity, specificity, and positive and negative predictive values were 66.7%, 66.7%, 81.5%, and 47.6%, respectively, for a normalized diameter of ≥4 mm.

CONCLUSIONS

The ability of TAU to identify an iliac vein stenosis of ≥50% is 96%. The positive predictive value for TAU to identify a ≥60% iliac vein area-reducing lesion is high, with moderate sensitivity and specificity. For patients with symptoms consistent with pelvic venous disorders secondary to PVI, TAU is a good preintervention screening modality for properly trained vascular imaging specialists with findings that correlate well with IVUS measurements.

Lycopene ameliorates locomotor activity and urinary frequency induced by pelvic venous congestion in rats

Decreased locomotor activity and altered urinary frequency are induced by bilateral common iliac vein ligation in rats. As a carotenoid, lycopene has a strong anti-oxidative function. This research investigated the function of lycopene in the pelvic venous congestion (PC) rat model and the underlying molecular mechanism. Lycopene and olive oil were administered intragastrically on a daily basis for 4 weeks after successful modeling. Locomotor activity, voiding behavior, and continuous cystometry were analyzed. The levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), nitrate and nitrite (NO _x ), and creatinine in the urine were measured. Gene expression in the bladder wall was analyzed by quantitative reverse transcription polymerase chain reaction, enzyme-linked immunosorbent assay, and Western blot. Locomotor activity, single voided volume, the interval between the bladder contractions, and urinary NO _x /cre ratio were all decreased in rats with PC, while the frequency of urination, urinary 8-OHdG/cre ratio, inflammatory responses, and nuclear factor-κB (NF-κB) signal activity were all increased. Lycopene treatment increased locomotor activity, decreased frequency of urination, elevated urinary NO _x level, and decreased urinary 8-OHdG level in the PC rat model. Lycopene also inhibited PC-enhanced pro-inflammatory mediator expression and NF-κB signaling pathway activity. In conclusion, lycopene treatment ameliorates PC-induced phenotypes and shows an anti-inflammatory effect in the PC rat model.

Nitinol stents placed in iliac veins are not associated with prolonged back pain

INTRODUCTION

Endovascular stenting is the standard of care for the management of symptomatic chronic venous obstruction. The increased radial resistive force and longer lengths of Nitinol stents have led to questions over persistent post-operative back pain. The purpose of this investigation was to assess the incidence and severity of post-operative back pain of Nitinol stents compared to Wallstents.

METHODS

A retrospective review of data at the Center for Vascular Medicine was performed. Patient demographics, pre-operative, one week, three-, six,- and 12 month visual analog pain scores (VAS) for back pain, stent type, diameter, length, and vein locations were assessed.

RESULTS

From April 2014 to November 2021, 627 (412 women/215 men) patients were assessed for the presence of post-operative back pain after an initial iliac vein stent placement. Stents utilized were Wallstents (n = 114), Venovo (n = 342), and Abre (n = 171). The most common Nitinol stent diameter and lengths were 14 mm, 16 mm, and 120 mm, respectively (p ≤ .03). The incidence of back pain at one week was 66% (411/627). VAS scores at one week and one, three, and six months post-operatively were the following: Wallstents-2.6 ± 3 (n = 66), 1.7 ± 2.6 (n = 43) 0.7 ± 2 (n = 51), and 0 ± 0 (n = 27); Abre-3.5 ± 3 (n = 130), 3.8 ± 3 (n = 19), 1.2 ± 2.5 (n = 12), and 1 ± 2 (n = 5); and Venovo- 2.5 ± 3 (n = 216), 2.4 ± 3 (n = 70), 0.9 ± 2 (n = 68), and 0.6 ± 1.7 (n = 49). There was no difference in the severity of back pain at any time point (p ≥ .99). The development of back pain was unrelated to stent type, diameter, length, or covered vein territory.

CONCLUSIONS

Post-operative back pain was observed in 66% of patients at one week. The average pain score at one week for the entire cohort was three, which declined to less than one at one month. No difference in the severity of back pain between groups was observed at any time point, and the development of back pain is unrelated to stent type, diameter, length, or covered vein territory.

Comprehensive overview of the venous disorder known as pelvic congestion syndrome

Pelvic venous disorders (PeVD) also known as Pelvic Congestion Syndrome (PCS) affect a great number of women worldwide and often remain undiagnosed. Gynecological symptoms caused by vascular background demand a holistic approach for appropriate diagnosis. This is a relevant cause of chronic pelvic pain and atypical varicose veins. The diagnosis is based on imaging studies and their correlation with clinical presentation. Although the aetiology of PCS still remains unclear, it may result from a combination of factors including genetic predisposition, anatomical abnormalities, hormonal factors, damage to the vein wall, valve dysfunction, reverse blood flow, hypertension and dilatation. The following paper describes an in-depth overview of anatomy, pathophysiology, symptoms, diagnosis and treatment of PCS. In recent years, minimally invasive interventions have become the method of first choice for the treatment of this condition. The efficacy of a percutaneous approach is high and it is rarely associated with serious complications.Key MessagesPelvic venous disorders demand a holistic approach for appropriate diagnosis.This article takes an in-depth look at existing therapies of Pelvic Congestion Syndrome and pathophysiology of this condition.Embolisation is an effective and safe treatment option.

An online survey of pelvic congestion support group members regarding comorbid symptoms and syndromes

Objectives

Patients with pelvic congestion syndrome (PCS) often report overlapping somatic symptoms and syndromes. The objective of this study was to explore the prevalence of co-existing symptoms and self-reported syndrome diagnoses among women with PCS and to inform future research hypotheses.

Methods

A brief online survey was offered to members of a PCS support group website. Responses were assessed for self-reported co-existing symptoms and formal diagnoses, including: chronic fatigue syndrome, fibromyalgia, postural tachycardia syndrome, irritable bowel syndrome, migraines, interstitial cystitis, and temporomandibular joint dysfunction.

Results

Of a total of 6000 members, there were 398 respondents; 232 (59%) had not yet been treated for PCS. Among these, the most prevalent co-existing symptoms were as follows: severe fatigue (72%), dizziness (63%), IBS symptoms (61%), brain fog (33%), migraines (49%), polyuria or dysuria (41%), excessive sweating (31%), TMJ pain (31%), and loose skin or lax joints (18%). These are much higher than reported for the general female population. The most commonly self-reported comorbid syndrome diagnoses for the overall group of 398 were: irritable bowel syndrome (29%), fibromyalgia (13%), spinal nerve problems (18%), interstitial cystitis (10%), postural tachycardia syndrome (9%), hypertension (11%), chronic fatigue syndrome (10%), and Ehlers-Danlos syndrome (6%). Other than with hypertension, these rates are variably higher than in the general population.

Conclusion

Several self-reported co-existing symptoms and syndromes are more prevalent in members of a PCS support group relative to the reported prevalence in the general population. More formal investigation is warranted to evaluate this finding and to investigate potential etiologic links. Ehlers-Danlos Syndrome appears to be common in self identifying PCS women.

Painful Ejaculation In A Patient With Pelvic Venous Insufficiency

Pelvic venous insufficiency (PVI) is common in women but has been rarely diagnosed in men. The clinical manifestations include varicocele and pelvic disturbances; however, we were unable to find a previous description of painful ejaculation as a symptom of PVI. We present the case of a 36-year-old man with a 7-year history of severe sharp ejaculatory pain. PVI was suspected after previous treatment attempts. The diagnosis was confirmed by descending phlebography, and he underwent coil embolization of the pelvic vessels and phlebotonic therapy. At 6 months after treatment, he reported a 75% improvement in his condition. Therefore, painful ejaculation should be considered an uncommon manifestation of PVI.

Embolization in pelvic venous disorders using ethylene vinyl alcohol copolymer (Onyx®) and Aetoxysclerol: a prospective evaluation of safety and long-term efficacy

OBJECTIVES

To prospectively evaluate the safety and efficacy of embolization using ethylene vinyl alcohol copolymer (Onyx^®) and Aetoxysclerol for treatment of pelvic venous disorders (PeVD).

METHODS

This prospective study was approved by the institutional ethics review board. Ten clinical parameters were retained for evaluation of PeVD (pelvic pain, dyspareunia, post-coital pain, menstruation pain, lower limbs pain, difficulty walking, aesthetic discomfort, impact on daily working life, psychological impact and impact on daily life), measured on a visual analogue scale (VAS) between 0 and 10, and a global score out of 100 was noted before embolization, after 3 months during the imaging follow-up, and at the end of follow-up by phone call. The main criterion was clinical efficacy of embolization defined by an impairment score < 40/100 and a 50% decrease in overall score. Complications were recorded. Visualization of Onyx^® on MRI 3 months after embolization was noted.

RESULTS

Between July 2017 and May 2019, 73 consecutive women (mean age ± SD [range]: 41 ± 11 years [25-77]) treated by embolization with Onyx^® and Aetoxysclerol were included. The median follow-up was 28 months [Q1-Q3: 24.0-29.2] (range: 18.1-34.5). The median initial VAS impairment score was 39/100 [29.75-48.50] (12-58). Clinical efficacy was obtained for 70 patients (70/73, 95.9%), and the median VAS impairment score at the end of follow-up was significantly lower at 3 [0.00-7.25] (0-73) (p < 0.0001). Four minor complications occurred. Onyx^® was visualized on DIXON sequence of MRI for all patients.

CONCLUSION

Embolization using Onyx^® and Aetoxysclerol for PeVD is safe and effective.

KEY POINTS

• Embolization using Onyx^® and Aetoxysclerol for pelvic venous disorders is safe and effective. • Imaging follow-up is facilitated by visualization of Onyx^® on MRI DIXON sequences.

Case Series: Superficial Sonography in Urgent Care

Sonography is an essential imaging modality, known for its real-time capabilities, relative low cost, and multiple diagnostic applications. Although there are protocols which are well-established for specific examinations, there are not clear guidelines for sonographic examinations of soft tissues. Many sonographers have to establish their own imaging protocols when completing a soft tissue examination. This case series details five soft tissue examinations that represent just a few of the clinical requests generated in an Urgent Care (UC) facility. Since UC usage has increased over the past several years, it appears likely that any sonographer working in such outpatient settings will benefit from as much exposure to soft tissue examinations as possible.

Nutcracker syndrome: diagnosis and therapy

Nutcracker syndrome (NCS) is an extrinsic compression of the left renal vein (LRV) by the superior mesenteric artery (SMA) anteriorly and aorta posteriorly resulting in renal vascular congestion manifesting as hematuria, proteinuria, orthostatic hypotension, pain, or even renal dysfunction. Long-standing venous compression can encourage collateral drainage pathways through gonadal and pelvic veins, which may explain reported symptom and syndrome overlap with pelvic congestion syndrome. Diagnosis can be challenging and variable, frequently involving a combination of ultrasound Doppler, cross-sectional, and invasive imaging. Often, intravascular pressure measurements are required to prove a renocaval pressure gradient to aid in a definitive diagnosis. Conservative management is appropriate, especially in children, who tend to outgrow the disorder. In the interim, medical management with angiotensin converting enzyme inhibitors (ACEIs) is a useful therapy to manage orthostatic hypotension in the pediatric population. In adults, invasive therapies are more frequently pursued. These are aimed at relieving the extrinsic compression on the LRV. The standard of care is renal vein transposition, with renal autotransplantation reserved for recalcitrant cases. Endovascular stenting is a less invasive option. Laparoscopic placement of an exovascular stent is a newer therapy intended to minimize trauma to the LRV. In this review, we will discuss the clinical manifestations, diagnostic criterion, imaging features, and conservative and surgical therapies for this condition.

Pelvic Congestion Syndrome: A Missed Opportunity

Background/Aims  Chronic pelvic pain (CPP) is pelvic pain for greater than 6 months with many potential causes one being pelvic congestion syndrome (PCS). PCS is diagnosed by clinical symptoms, exclusion of other etiologies, and imaging. Given the complex nature and diagnosis of CPP, we examined ordering and referral patterns in our local population to understand how the imaging findings of PCS correlate with patient symptoms and referral and treatment. Materials and Methods  After IRB approval, we searched all 18 to 70-year-old females with CT of the pelvis between March 2015 and March 2018 with the terms "pelvic" plus "congestion," "varices," or "vein dilation" in the dictation. Via electronic medical record and image review we collected data regarding demographics, clinical presentation, symptoms, imaging findings, ordering provider, and any follow-up/referrals or interventions regarding PCS. Results  A total of 96 patients were included of the 197 studies, with an average age of 47 years and average body mass index of 19.3 ( n  = 93) at the time of imaging. The reason for imaging was often acute abdominal or flank pain ( n  = 22) with 38% of cases ordered from the emergency room. Only 72 patients had documentation of clinical evaluation for symptoms of PCS. Notably, only 20 were referred for their symptoms, and only two patients were referred to IR. Both patients underwent successful endovascular intervention. Conclusion  CPP is a common cause of morbidity with PCS representing an underdiagnosed cause. We demonstrate that while imaging findings may be incidental, we are failing to capture and triage patients with clinical symptoms of PCS. Radiologists can play a key role in the care of these patients.

Is the Prevalence of Estimated Pelvic Congestion Higher Than Examined? A Retrospective Study of Consecutive Abdominopelvic Computed Tomography Analyses

BACKGROUND

Chronic pelvic pain (CPP) is a common complaint in women, and is the key factor in the diagnosis of pelvic congestion syndrome (PCS).

INTRODUCTION

Consecutive abdominal and pelvic computed tomography (CT) scans in adult female patients not diagnosed with PCS and collected over a period of 3 years were evaluated retrospectively to determine the prevalence of underestimated pelvic congestion (PC).

METHODS

500 consecutive abdominal and pelvic CT scans collected from female patients aged 18-80 years were retrospectively analyzed for the presence of PC.

RESULTS

90 of the CT scans examined showed the presence of PC (18 %). These patients were divided into two groups: Group I had 52 scans with unilateral PC, while Group II had 38 scans with the bilateral enlarged ovarian vein (OV). Left and right OV diameters were measured as 7.14±2.15 and 5.56±1.87 mm, respectively. Co-occurrence of additional vascular anomalies, such as nutcracker-type compression of the left renal vein, and May Thurner, was significantly higher in Group I than Group II (p<0.001). The diameter of the OV remained wide irrespective of age in Group I, but showed a decrease with increasing age in Group II. The most common complaint was abdominal pain; these patients required an average of six referrals to two different clinics (primarily general surgery and internal medicine) before being diagnosed with PC.

CONCLUSION

The diagnosis of PCS remains to be an important problem for patients because of insufficient perception of physicians. PCS should be considered in female patients with complaints of chronic abdominal and pelvic pain and CT may be a valuable examination tool for diagnosis.

Pelvic Venous Congestion Secondary to a Circumaortic Renal Collar in an Adolescent Female: Report of a Case

We report a 13-year-old girl who presented with a recurrent abdominal pain that started after her menarche. The abdominal palpation revealed tenderness over the left ovarian point. The laboratory study, ultrasonography, and abdominal X-ray were normal. The computed tomography and magnetic resonance imaging showed a double left renal vein with a retroaortic component, an increased left parauterine circulation, and ipsilateral ovarian vein engorgement. A diagnostic and therapeutic phlebography allowed a selective catheterization of a group of pelvic varicose veins draining to the left ovarian and to the internal iliac veins. There were no complications during the procedure and the symptoms disappeared 2 days later. Circumaortic left renal vein may cause hematuria, proteinuria, pelvic congestion syndrome, and massive hemorrhage during surgery. A conservative treatment is recommended for patients without gynecourological/renal symptoms or with mild hematuria. The endovascular treatment by gonadal venous embolization is safe and effective.

Incidental Ovarian and Uterine Findings on Cross-sectional Imaging

Incidental adnexal masses and uterine findings occur with a high frequency on cross-sectional imaging examinations, particularly in postmenopausal women in whom imaging is performed for a different reason. These incidentalomas encompass a gamut of potential pelvic gynecologic disorders. Most are benign ovarian cysts; however, other less commonly encountered disorders and improperly positioned gynecologic devices may be seen. A knowledge of the management recommendations for such pelvic incidental findings is critical to avoid unnecessary imaging and surgical interventions, as well as to avoid failure in diagnosis and management of some of these conditions.

Management of Patients when Superficial Venous Disease Arises from Pelvic Escape Points

Chronic pelvic pain (CPP) is a common condition in women that carries with it significant morbidity. It is commonly seen in patients presenting to obstetrics and gynecology outpatient clinic visits. CPP is a presenting symptom of various pathologies including pelvic varicocele, pelvic adhesions, spastic colon syndrome, uterine fibroids, endometriosis, and psychosomatic disorders. Pelvic congestion syndrome has more recently been termed "pelvic venous insufficiency (PVI)" due to the underlying retrograde flow through incompetent ovarian and pelvic veins that are thought to cause the symptoms of CPP. Pelvic varices can commonly present alongside vulvar, perineal, and lower extremity varices. There are some predictable "escape pathways" for these varices that may present for interventional treatment. This article introduces the reader to current terminology, clinical presentation, diagnosis, and treatment of patients with pelvic varices due to PVI.

Pelvic congestion syndrome (PCS) as a pathology of postmenopausal women: a case report with literature review

Background

Due to the scarcity of adequately powered, randomized controlled trials and internationally standardized diagnostic criteria, evidence on the diagnosis and treatment of pelvic congestion syndrome (PCS) is limited. Earlier epidemiologic observations led to the attribution of PCS to the premenopausal state, and a remission of symptoms after menopause is frequently described a hallmark of the pathology. This concept has currently been challenged by radiological studies reporting a notable prevalence of ovarian venous congestion in adult female patients of advanced age. PCS as a pathology of postmenopausal women, however, has not been acknowledged by systematic research to date, impeding appropriate diagnostics and therapy for affected patients.

Case presentation

A 69-year-old postmenopausal patient presented with newly diagnosed dilated and insufficient pelvic veins in combination with characteristic pain anamnesis, thereby fulfilling the diagnostic criteria of PCS. Interventional coil embolization of both ovarian veins as a standard treatment previously described for premenopausal patients was successfully performed, resulting in prompt alleviation of symptoms. The patient remained symptom-free at the 18-month follow-up visit.

Conclusions

Given this first systematically documented case of a patient with postmenopausal symptomatic PCS in the light of recently published data on the prevalence of ovarian venous congestion in patients of advanced age, it may be assumed that PCS is not to be considered a pathology strictly limited to premenopausal state. Further clinical studies expanding the diagnostic scope beyond menopause may help to substantiate evidence and subsequently define standardized therapeutic approaches for affected postmenopausal patients.

Imaging of Pelvic Venous Disorders (PeVD); Should Every Patient Get an MRI?

Pelvic venous disease (PeVD) is part of the broad differential diagnosis of chronic pelvic pain with a challenging diagnosis and clinical workup to identify those patients that are most likely to benefit from intervention. Ultrasound, MRI, CT, venography, and intravascular ultrasound can all provide information to aid in the diagnostic algorithm. The purpose of this article is to review imaging as a component of the outpatient workup of patients with chronic pelvic pain to guide appropriate understanding and use of imaging modalities to accurately identify patients suffering from PeVD. A favored approach is to begin with transabdominal sonography with selective use of MRI/MRV in specific patient populations.

Ovarian Vein Embolization: How and When Should It Be Done?

Pelvic Venous Disease (PeVD) is characterized by pelvic varicosities and chronic pelvic pain, defined as noncyclic pelvic pain that persists for more than 6 months. Pain and discomfort related to PeVD typically worsen with upright positioning and occur more frequently in multiparous and premenopausal women. The most common cause of PeVD is pelvic venous insufficiency (PVI) due to incompetent valves. Noninvasive imaging modalities such as ultrasound, computed tomography, or magnetic resonance imaging, and invasive catheter-based venography can help characterize varicosities and venous insufficiency, supporting the diagnosis of PeVD. In patients with PeVD, ovarian and/or internal iliac vein embolization demonstrate excellent technical and clinical success rates with relatively low complication rates and should be considered as standard management, in conjunction with medical therapy. Appropriate diagnostic work-up and patient selection are important prior to any intervention for achieving therapeutic success, as multiparous women have a higher success rate compared to patients with dyspareunia after embolization therapy. Post-procedure follow-up is critical for assessing symptom improvement and need for repeat intervention. However, further research is needed to identify additional predictors of successful outcomes after embolization therapy. This article aims to provide an overview of patient selection, interventional technique, challenges, and outcomes of ovarian vein embolization.

Pelvic venous insufficiency secondary to iliac vein stenosis and ovarian vein reflux treated with iliac vein stenting alone

BACKGROUND

We have previously reported that in women with a pelvic venous disorder secondary to pelvic venous insufficiency, 56% will present with an iliac vein stenosis (IVS) and ovarian vein reflux (OVR). The purpose of the present investigation was to determine whether women with combined disease can be treated using iliac vein stenting alone.

METHODS

A retrospective review of prospectively collected data at the Center for Vascular Medicine was performed. We investigated women with pelvic pain or dyspareunia secondary to combined IVS and OVR who had undergone stenting alone. The patient demographics, pre- and 6-month postoperative visual analog scale (VAS) for pain scores, stent type, stent diameter, stent length, and ovarian vein diameters were assessed. All patients had undergone diagnostic venography of their pelvic veins, left ovarian veins, and pelvic reservoirs and intravascular ultrasonography of their iliac veins.

RESULTS

From May 2016 to October 2019, 82 patients with a pelvic venous disorder secondary to IVS and OVR were identified. The present data analysis focused on 38 patients with complete pre- and postoperative VAS scores and duplex scan stent patency data at 6 months. The pelvic and dyspareunia VAS scores at the initial and 6-month follow-up visits were as follows: 6.83 ± 3.19 and 4.24 ± 2.65 and 1.72 ± 2.01 and 0.05 ± 2.0, respectively (P ≤ .001). At 6 months, 29 of the 38 women (76%) reported complete resolution of all symptoms, 26 of 28 (93%) reported complete resolution of their dyspareunia, 5 of 38 (13%) reported significant improvement, and 4 of 38 (10%) reported no improvement. The average ovarian vein diameter was 6.7 ± 2.5 mm. The average stent size and length was 18.20 ± 1.6 mm and 92.41 ± 18.5 mm, with 25 placed in the left common iliac, 2 in the right common iliac vein, and 3 bilaterally. Of the 38 patients, 7 required reintervention (18%). An untreated pelvic reservoir was observed in 17 of the 38 patients (44%). One of the two with no response and six of the patients with improvement had OVR and an untreated pelvic reservoir. The remaining 10 patients with a pelvic reservoir had experienced complete resolution of their symptoms with stenting alone.

CONCLUSIONS

Of the 38 women with pelvic pain secondary to combined IVS and OVR, 76% achieved complete symptom resolution with iliac vein stenting alone. Most of the women with a pelvic reservoir were asymptomatic and reported full symptom resolution after stenting alone. However, these data suggest that in some women, a relationship might exist between the presence of a pelvic reservoir and the persistence of symptoms. Therefore, for women with combined IVS and OVR, we recommend iliac vein stenting alone and staged ovarian vein embolization only for women with persistent symptoms.

Ovarian Vein Thrombosis: A Narrative Review

Ovarian vein thrombosis (OVT) is a rare type of venous thromboembolism. The most common risk factors for OVT include pregnancy, oral contraceptives, malignancies, recent surgery, and pelvic infections; however, in 4 to 16% of cases, it can be classified as idiopathic. Most of the available information regards pregnancy-related OVT, which has been reported to complicate 0.01 to 0.18% of pregnancies and to peak around 2 to 6 days after delivery or miscarriage/abortion. The right ovarian vein is more frequently involved (70-80% of cases). Clinical features of OVT include abdominal pain and tenderness, fever, and gastrointestinal symptoms. The most typical finding is the presence of a palpable abdominal mass, although reported in only 46% of cases. OVT can be the cause of puerperal fever in approximately a third of women. Ultrasound Doppler is the first-line imaging, because of its safety, low cost, and wide availability. However, the ovarian veins are difficult to visualize in the presence of bowel meteorism or obesity. Thus, computed tomography or magnetic resonance imaging is often required to confirm the presence and extension of the thrombosis. In oncological patients, OVT is often an incidental finding at abdominal imaging. Mortality related to OVT is nowadays low due to the combination treatment of parenteral broad-spectrum antibiotics (until at least 48 hours after fever resolution) and anticoagulation (low-molecular-weight heparin, vitamin K antagonists, or direct oral anticoagulants). Anticoagulant treatment duration of 3 to 6 months has been recommended for postpartum OVT, while no anticoagulation has been suggested for incidentally detected cancer-associated OVT.

[Immediate and remote results of endovascular embolization of ovarian veins]

Presented in the article is a prospective study of endovascular embolization of ovarian veins in female patients suffering from primary pelvic varicose veins, with the assessment of the immediate and remote results, as well as a 1-year follow up.

AIM

The aim of our investigation was a comprehensive clinical and instrumental assessment of efficacy of endovascular embolization in women with pelvic varicose veins.

PATIENTS AND METHODS

Our single-centre study included a total of 29 female patients presenting with pelvic varicose veins and undergoing embolization of ovarian veins using microcoils, in 5 cases the procedure was supplemented with injecting a foam sclerosant.

RESULTS

The technical success of endovascular occlusion of ovarian veins amounted to 100%. Two women immediately after the operation were subjected to a redo intervention: in one case - resection of the ovarian vein and in the second case - repositioning of the microcoils. In the remote period, one patient due to recurrent relapses underwent repeat embolization followed by retroperitoneal resection of the ovarian vein. The findings of the clinical methods of examination demonstrated a decrease in the intensity of manifestations of pelvic varicose veins according to the pelvic venous clinical severity score and visual analogue scale, as well as improvement of the women's quality of life.

CONCLUSION

Endovascular occlusion of ovarian veins is a highly effective, minimally invasive, and safe method of treatment of female patients with incompetent ovarian veins. Endovascular treatment may be regarded as a method of choice in management of the primary form of pelvic varicose veins.

Medicine and Phlebolymphology: Time to Change?

Biomedical science is undergoing a reappraisal of its scientific advancement process and of the related healthcare management. Progress in medicine should combine improvements of knowledge, efficacy, and safety of diagnostic/therapeutic procedures, with adequate cost-effectiveness profiles. This narrative review is aimed at assessing in medicine, more specifically in phlebology and lymphology: (a) scientific literature possible biases, (b) the level of evidence, comprehensiveness, and cost-effectiveness of the main therapeutic options, and (c) the possible contribution of integrative and translational medicine. Current medical research may have cognitive biases, or industry-tied influences, which impacts clinical practice. Some reductionism, with an increasing use of drugs and technology, often neglecting the understanding and care of the root causative pathways of the diseases, is affecting biomedical science as well. Aging brings a relevant burden of chronic degenerative diseases and disabilities, with relevant socio-economic repercussions; thus, a major attention to cost-effectiveness and appropriateness of healthcare is warranted. In this scenario, costly and innovative but relatively validated therapies may tend to be adopted in venous and lymphatic diseases, such as varicose veins, leg venous ulcer, post-thrombotic syndrome, pelvic congestion syndrome, and lymphedema. Conversely, a more comprehensive approach to the basic pathophysiology of chronic venous and lymphatic insufficiency and the inclusion of pharmacoeconomics analyses would benefit overall patients’ management. Erroneous lifestyle and nutrition, together with chronic stress-induced syndromes, significantly influence chronic degenerative phlebo-lymphatic diseases. The main active epigenetic socio-biologic factors are obesity, dysfunctions of musculo-respiratory-vascular pumps, pro-inflammatory nutrition, hyperactivation of stress axis, and sedentarism. An overall critical view of the scientific evidence and innovations in phebolymphology could be of help to improve efficacy, safety, and sustainability of current practice. Translational and integrative medicine may contribute to a patient-centered approach. Conversely, reductionism, eminence/reimbursement-based decisional processes, patients’ lack of education, industry-influenced science, and physician’s improvable awareness, may compromise efficacy, safety, appropriateness, and cost-effectiveness of future diagnostic and therapeutic patterns of phlebology and lymphology.

Pelvic Congestion Syndrome

Pelvic congestion syndrome (PCS) is often an underdiagnosed cause of chronic pelvic pain in female patients with radiology detection of gonadal vein dilatation and parauterine varices. It may occur either alone or in combination with vulvar varicosities and/or lower extremity venous insufficiency. Although transcatheter venography represent the gold standard for PCS diagnosis, it is performed after inconclusive noninvasive imaging such as Doppler Ultrasound, CT scan, and MRI. Once diagnosis has been confirmed, management of PCS include medical, surgical, and endovascular therapy. Medical and surgical treatments have been shown to be less effective than transcatheter pelvic vein embolization. This latter has been proven to be a safe, effective, and durable therapy for the treatment of PCS. Numerous studies have shown their results in PCS endovascular treatment, but neither of them has been subjected to an adequate randomized controlled trial. A well-designed randomized controlled trial is urgently needed to assess transcatheter embolization clinical success.

Microsurgical gonadal-inferior epigastric vein anastomosis to treat the nutcracker phenomenon with left gonadal vein varices with reflux

OBJECTIVE

To evaluate the effectiveness and safety of microsurgical gonadal-inferior epigastric vein anastomosis for the treatment of the nutcracker phenomenon (NCP) associated with left gonadal vein varices with reflux.

METHODS

Thirty-five patients with NCP associated with left gonadal vein varices with reflux diagnosed in our hospital from June 2016 to June 2018 were included. All patients underwent a shunt operation consisting of microsurgical gonadal-inferior epigastric vein anastomosis, and the patients were followed up for 1 year.

RESULTS

All patients were successfully operated on, with an average operation time of 96.5 ± 12.3 min. After a 1-year follow-up, the symptom of gross hematuria disappeared in 3 patients (including 1 woman). For the other 32 patients, the sperm concentration (27.43 ± 8.68 × 10⁶/ml) and motility (33.06 ± 4.27%) postoperatively were significantly higher than that preoperatively (16.21 ± 6.43 × 10⁶/ml and 23.48 ± 4.43%, respectively) (P < 0.05); among these patients, 2 had natural pregnancies with their spouses. The peak velocity (PV) at the aortomesenteric portion of the left renal vein (LRV) and the PV ratio between the aortomesenteric and hilar portion of the LRV significantly decreased after surgery (117.9 ± 30.4 cm/s vs 76.6 ± 18.5 cm/s; 7.3 ± 0.7 vs 4.1 ± 0.4). Two patients had complications of mild hydroceles requiring no intervention, and no major complications were observed during and after surgery.

CONCLUSION

Our results suggest that the microsurgical gonadal-inferior epigastric vein anastomosis is both effective and safe to treat patients with gonadal varicose veins caused by the nutcracker phenomenon.

[A case of successful endovascular treatment of a patient with chronic pelvic pain and recurrent varicocele]

Described in the article is a clinical case report regarding diagnosis and treatment of pelvic varicose veins in a 34-year-old male patient presenting with compressive stenosis of the left common iliac vein (May-Thurner syndrome). The man had developed clinical symptoms of the disease as varicocele when he was 17 years old. Multiple surgical interventions on the veins of the spermatic cord failed to result in significant success. The diagnosis was verified by means of ultrasound examination and contrast X-ray phlebography. The patient was subjected to balloon angioplasty and stenting of the compressive stenosis of the left common iliac vein. The endovascular treatment performed was followed by the patient's improved condition, confirmed by methods of instrumental diagnosis, as well as by regression of clinical symptomatology.

Imaging Appearance and Nonsurgical Management of Pelvic Venous Congestion Syndrome

Pelvic venous congestion syndrome (PVCS) is a challenging and complex cause of chronic pelvic pain in female patients. PVCS due to incompetent vein valves is the combination of gonadal vein reflux and pelvic venous engorgement in patients with chronic pelvic pain without other causes. However, pelvic venous engorgement and gonadal vein reflux can be seen in patients without pelvic pain, which makes obtaining a detailed history and physical examination important for workup and diagnosis. The underlying cause of PVCS may be incompetent gonadal vein valves or structural causes such as left renal vein compression with an incompetent gonadal vein valve (nutcracker syndrome) or iliac vein compression (May-Thurner configuration) with reflux into the ipsilateral internal iliac vein. Venography is considered the criterion standard for imaging diagnosis; however, more recently, US and MRI have been shown to provide adequate accuracy for diagnosis. Noninvasive imaging studies aid in the diagnosis of PVCS and also aid in pretreatment planning. When PVCS is caused by incompetent gonadal vein valves, treatment typically is performed by means of embolization via a minimally invasive catheter with excellent technical and clinical success rates. When PVCS is caused by venous obstruction, the obstruction must be treated first before gonadal vein embolization and sclerotherapy are considered. ^©RSNA, 2019 Online supplemental material is available for this article.

Role of Interventional Procedures in Obstetrics and Gynecology

Radiological guided intervention techniques are discussed in obstetric and gynecologic patients. Fallopian tube recanalization, postpartum hemorrhage control, techniques of treating uterine leiomyomas, pelvic congestion treatment, and the use of percutaneous and transvaginal ultrasonography-guided aspirations and biopsy are covered. These techniques use basic radiological interventional skills and show how they are adapted for use in the female pelvis.

A cadaveric study of ovarian veins: variations, measurements and clinical significance

The literature showing information regarding ovarian venous variation, its diameter and termination distance from respective renal venous origin are limited. This information is important in various surgical and clinical procedures including venous embolization, vascular reconstruction during renal transplantation and localizing the source of origin of a pelvic mass. We examined 94 sides of 47 formalin fixed female cadavers and noted the course and termination of ovarian veins. We measured the diameter of ovarian veins at their termination point and the termination distance in respect to the termination point of renal veins at inferior vena cava (IVC) on respective sides. We found two cases of variations related to right ovarian vein -one, right ovarian vein joined the right renal vein; two, right ovarian vein duplicated and joined with IVC at two different points. We found one case of variation related to left ovarian vein-a partially duplicated left ovarian vein. All the variations were unilateral. The mean diameters of right and left ovarian veins were 3.66±1.18 and 4.20±0.96 mm, respectively. The distance of termination of ovarian veins ranged from 19-40 mm and 13-41 mm, respectively from termination points of right and left renal veins at IVC on respective sides. Our study presents a set of data regarding variation of ovarian veins, diameters and termination distances which could be useful for gynecologists, surgeons and radiologists.

[Method of determining disease severity in women with pelvic varicose veins]

BACKGROUND

Using assessment scales in clinical and research practice is one of fundamental reference methods of evaluation in human pathological states. Pelvic vein varicosity is an independent nosological entity within the framework of chronic vein diseases. Currently, the clinical methods of assessment in the aspect of a patient-oriented approach in this type of disease are largely understudied and still not duly defined.

AIM

The study was aimed at analyzing clinical outcomes of surgical treatment in the form of resection of the ovarian vein in female patients with pelvic varicose veins, based on the developed specialized scale of clinical assessment of disease severity.

PATIENTS AND METHODS

We carried out an open prospective study of efficacy of resection of the ovarian vein in 37 women with pelvic varicose veins. The main criterion for assessment was a clinical method of determining manifestations of the disease by means of the Pelvic Venous Clinical Severity Score.

RESULTS

According to the Pelvic Venous Clinical Severity Score, improvement of the condition was observed in 36 (97.3%) operated female patients and 1 (2.7%) woman turned out to have negative dynamics. The median of the composite score of the severity scale decreased form 11.78±5.06 points to 5.22±3.19 (p<0.05). The total positive gradient of the score amounted to 6.57±3 .65 points. A significant decrease in manifestations of severity was observed for 9 of the 10 clinical descriptors of the disease.

CONCLUSION

The use of the suggested scale in practical assessment of the results made it possible to prove high efficacy of resection of the ovarian vein in women with pelvic varicose veins in the form of decreased intensity of the disease's symptomatology. The VCSS is an easy-to-fill-in tool, taking up little time, ensuring no influence of the physician's personality on the answers, presenting quantitative expression of therapeutic results.

The Effect of a Subsequent Pregnancy After Ovarian Vein Embolization in Patients with Infertility Caused by Pelvic Congestion Syndrome

RATIONALE AND OBJECTIVES

To report the effect of pregnancy on patients who have undergone pelvic vein embolization with pelvic congestion syndrome, which was suspected to be the only cause of infertility.

MATERIAL AND METHODS

Data from a total of 12 women (mean age: 36.5 ± 4.3 years, range: 29-45 years) were collected between May 2013 and June 2016. Transvenous embolization with fibre platinum coils combined with anhydrous alcohol was performed in unilateral or bilateral ovarian veins after the diagnosis of venous varices confirmed by transvaginal ultrasound or pelvic venography. The follow-up time was 2-3 years. The primary outcomes of this study were the technical procedure and clinical effect, especially the pregnancy rate and complications.

RESULTS

The successful embolization rate was 100% with no significant complications during or after embolization. Ovarian vein embolization was performed unilaterally (7/12, 58.3%) or bilaterally (5/12, 41.7%). A total of 66.7% (8/12) of women had a subsequent pregnancy and complete pelvic pain relief, and 33.3% (4/12) of patients had partial pain relief. The numeric pain perception scores improved from 6.7 ± 1.1 to 2.7 ± 1.2 (p < 0.001).

CONCLUSION

Ovarian varices may be associated with infertility in some patients, and embolization of ovarian varices is a safe and effective method for those trying to become pregnant.

Incidence and distribution of lower extremity reflux in patients with pelvic venous insufficiency

Introduction

Women with pelvic venous insufficiency often present with lower extremity symptoms and manifestations of chronic venous disorders. The purpose of this investigation was to determine the incidence of lower extremity chronic venous disorders and the types and distribution of lower extremity veins involved in patients with a known diagnosis of pelvic venous insufficiency.

Methods

Between January 2012 and December 2015, we retrospectively reviewed the charts of 227 women with pelvic venous insufficiency as well as their lower extremity venous duplex investigations. Presenting symptoms, Clinical, Etiology, Anatomy, Pathophysiology (CEAP) class, initial revised Venous Clinical Severity Score (rVCSS) and the types of lower extremity veins with reflux and their locations were noted. Patients were also subcategorized according to their primary pelvic disorder as follows: Entire cohort (PVI), Ovarian vein reflux (OVR), Iliac vein stenosis (IVS) or both (OVR + IVS).

Results

The study group consisted of 227 women (454 limbs) with documented pelvic venous insufficiency. The average age was 44.71 ± 10.2 years. In decreasing order, patients presented with the following lower extremity symptoms: pain (66%), swelling (32%), heaviness (26%), limb fatigue (13%), itching (13%), leg cramps (10%), skin changes or Superficial Venous Thrombosis (SVT) (2%) and ulceration or bleeding (0.08%). Table 1 outlines the CEAP class for 215 of the 227 patients. For the entire cohort, 48% of right and 50% of left limbs demonstrated C0 or C1 disease. The incidence and type of symptomatic lower extremity veins were as follows: any axial vein, 32%; great saphenous vein (GSV), 21%; small saphenous vein (SSV), 11%; GSV and SSV, 5%; non-saphenous tributaries, 15%; saphenous tributaries, 12%; posterior or postero-lateral thigh distribution, 5%; vulvar distribution, 4%; perforators, 4%; deep veins, 2%; and anterior accessory saphenous veins, 1%. For the GSV and SSV, the following patterns of reflux were observed: entire GSV, 4%; entire above knee GSV, 2%; entire below knee GSV, 2%; above knee segmental GSV, 20%; below knee segmental GSV, 21%; above and below knee GSV segmental disease, 1%; entire SSV, 4%; and SSV segmental disease, 12%. The incidence of reflux in any axial vein, the GSV and anterior accessory GSV was greater in the OVR group compared to IVS or OVR + IVS (p ≤ 0.03). In addition, 64 of 227 (28%) patients had a history of prior lower extremity venous ablations: OVR (10/39, 26%), IVS (15/50, 30%) and OVR + IVS (39/127, 9%). The number of ablations per patient was as follows—OVR: 1.48 ± 0.5, IVS: 1.7 ± 0.7 and OVR + IVS: 1.65 ± 0.7.

Conclusion

At least 50% of patients with pelvic venous insufficiency present with lower extremity venous disease. The incidence of reflux in any axial vein is greatest in the OVR group suggesting a correlation with hormonal fluctuations and pregnancy. The majority of symptomatic patients present with segmental axial GSV or SSV disease. Although vulvar and gluteal escape veins are highly associated with pelvic venous insufficiency, they are infrequently observed. In patients who experience residual or persistent symptoms after treatment for chronic venous disorders, a pelvic venous ultrasound should be performed to assess the presence of pelvic venous insufficiency.

Transient increased tumescence of the glans penis during penile erection after endovenous ablation of the great saphenous vein

OBJECTIVE

The primary objective of our study was to investigate the impact of endovenous ablation of the great saphenous vein (GSV) on the degree of tumescence of the glans penis during penile erection as well as on global erectile function (EF).

METHODS

We included patients scheduled for one of three different methods of endoluminal treatment. Our questionnaire was composed of the EF domain of the International Index of Erectile Function, an additional question that has been validated for assessment of swelling (tumescence) of the glans penis, and a question on the use of erectogenic medication.

RESULTS

There were 62 patients enrolled in the study. Seven patients (11%) reported a postoperative enlargement of the glans penis on penile erection compared with the subjectively assessed glans tumescence before surgery. Three patients (5%) reported an increased tumescence of the glans 1 week after surgery, and four (7.4%) different patients reported the effect 3 months after surgery. Of these seven men, three had normal EF (score ≥26) at any time. One patient had mild erectile dysfunction before the operation, with an improvement to normal EF from week 1 throughout the observation in the study (3 months).

CONCLUSIONS

This is the first prospective study that confirms an unexpected side effect of endoluminal treatment of the GSV occurring in approximately 10% of men. It might be of interest for insufficient responders to phosphodiesterase type 5 inhibitors with varicosis of the GSV in the future.

Application of 64-slice MSCT with ovarian vein tracking technique in identification of suture-fixed transposed ovaries

OBJECTIVE

To explore the accuracy of 64-slice multislice computed tomography with ovarian vein tracking technique in identification of surgically transposed ovaries.

METHODS

The CT and clinical data of 84 patients with ovarian transposition were retrospectively analyzed. Two radiologists completed the assessments independently. The CT data were analyzed twice. During the first assessment, transposed ovaries were identified on both sides of the lower paracolic gutters on enhanced axial CT images. The second assessment was carried out two months later. The presence or absence of transposed ovaries was identified by ovarian vein tracking technique. If the adjacent colon of the transposed ovary was not filled with contrast agents, two radiologists measured the CT values of the solid-appearing area of the transposed ovary and the wall of the adjacent colon.

RESULTS

84 patients with cervical cancer underwent ovarian transposition. There were 98 transposed ovaries and 70 non-transposed ovaries. The sensitivity, specificity and accuracy of the two assessments in identification of the ovaries were 72.4%, 98.6%, and 83.3% (first assessment), and 93.9%, 100% and 96.4% (second assessment). The sensitivity and accuracy of the two assessments were significantly different (p < 0.01). The solid-appearing area of the transposed ovaries and the wall of the adjacent colon in 33 cases showed soft tissue density. The CT values were (44.44 ± 5.78) HU and (44.50 ± 6.30) HU. The CT values were no significant difference (p > 0.05).

CONCLUSION

Ovarian vein tracking technique can accurately identify the unmarked transposed ovaries, which is crucial in the diagnosis of abdominal/pelvic lesions.

Pelvic Congestion Syndrome: Systematic Review of Treatment Success

Pelvic venous insufficiency is now a well-characterized etiology of pelvic congestion syndrome (PCS). The prevalence of CPP is 15% in females aged 18 to 50 years in the United States and up to 43.4% worldwide. In addition to individual physical, emotional, and quality-of-life implications of CPP, there are profound healthcare and socioeconomic expenses with estimated annual direct and indirect costs in the United States in excess of 39 billion dollars. PCS consists of clinical symptoms with concomitant anatomic and physiologic abnormalities originating in venous insufficiency. The etiology of PCS is diverse involving both mechanical and hormonal factors contributing to venous dilatation (>5 mm) and insufficiency. Factors affecting the diagnosis of PCS include variance of causes and clinical presentations of pelvic pain and relatively low sensitivity of noninvasive diagnostic imaging and laparoscopy to identify insufficiency compared with catheter venogram. A systematic review of the literature evaluating patient outcomes following percutaneous treatment of PCS is presented.

Noninvasive diagnostic tools for pelvic congestion syndrome: a systematic review

Introduction

In the work‐up of patients with suspected pelvic congestion syndrome, venography is currently the gold standard. Yet if non‐invasive diagnostic tools are found to be accurate, invasive venography might no longer be indicated as necessary.

Material and methods

A literature search in Pubmed and EMBASE was performed from inception until 6 May 2017. Studies comparing non‐invasive diagnostic tools to a reference standard in the work‐up of patients with (suspected) pelvic congestion syndrome were included. Relevant data were extracted and methodological quality of individual included studies was assessed by the Quality Assessment of Diagnostic Accuracy Studies (QUADAS‐2) tool.

Results

Nine studies matched our inclusion criteria. Six studies compared ultrasonography to venography and three studies described a magnetic resonance imaging technique. In using transvaginal ultrasonography, the occurrence of a vein greater than five mm crossing the uterine body had a specificity of 91% (95% CI; 77–98%) and occurrence of pelvic varicoceles a sensitivity and specificity of 100% (95% CI; 89–100%) and 83–100% (95% CI; 66–93%), respectively. In transabdominal ultrasonography, reversed caudal flow in the ovarian vein accounted for a sensitivity of 100% (95% CI; 84–100%). Detection of pelvic congestion syndrome with magnetic resonance imaging techniques resulted in a sensitivity varying from 88 to 100%.

Conclusions

The sensitivity of ultrasonography and magnetic resonance imaging seem to be adequate, which indicates a role for both tests in an early stage of the diagnostic workup. However, due to methodological flaws and diversity in outcome parameters, more high standard research is necessary to establish a clear advice for clinical practice.

Erectile function improvement after endovenous varicosis therapy of the great saphenous vein

There are no cases reported about endovascular varicosis therapy having an impact on the erectile function of the man. This case reports’ patient had a stronger erection in the area of the glans penis after he underwent endovenous lasertherapy of the great saphenous vein.

This effect could also be explained with the anatomy of the veins because some of the blood of the penis is drained by the external pudendal vein which leads into the saphenofemoral junction. If there is a manipulation on the veins of the saphenofemoral junction it might have an impact on the drainage of the penis.

Correlation between pelvic congestion syndrome and body mass index

OBJECTIVE

Previous studies of men suggested that patients with varicocele may be leaner than the normal population. No such work exists in women with pelvic congestion syndrome (PCS). This study evaluated the correlation between body mass index (BMI) and PCS.

METHODS

A case-control study at a single institution was performed of women who had the objective diagnosis of PCS. Data were prospectively collected for 100 consecutive patients with PCS. BMI was calculated for every patient and categorized into normal weight (BMI <25), overweight (BMI 25-29.9), and obese (BMI >30). Diagnosis of PCS was made by ultrasound and venography. Mean BMI was compared with that of the general female population of the United States from 1999 to 2002. Furthermore, analyses included comparison of patients with and without ovarian vein dilation and pelvic varices.

RESULTS

There were 100 women with a median age of 44 years (range, 24-73 years). The mean BMI of the study group was 25 ± 5.6 kg/m². The cohort was categorized into 59 women with normal BMI, 23 overweight women, and 18 obese women. The study cohort's BMI was less than that of the general U.S. female population (P = .02). The majority of the study group were white with lower BMI (P < .0001). Leg varicosities were more prevalent in obese patients (100% obese vs 81% normal BMI; P = .01). Patients with ovarian vein dilation had significantly lower BMI (24.1 ± 5.6 kg/m² and 26.7 ± 5.4 kg/m²; P = .036). No differences were identified for pelvic varices or reflux.

CONCLUSIONS

Women with PCS are more likely to have a normal BMI with ovarian vein dilation compared with obese women, who are more frequently affected by leg varicosities.
