01Approach to the Critical Patient/attcp27

Immediate priorities

›Acute pelvic pain assessment

›Hemodynamic instability — SBP <90 mmHg or MAP <65 mmHg mandates immediate resuscitation

›IV access x2 large bore

›Crystalloid bolus 1L isotonic saline

›PCS itself is rarely life-threatening; critical presentation implies alternative or concurrent diagnosis

›Ruptured ectopic pregnancy must be excluded first

›Ovarian torsion requires emergent surgical consultation

›If hemodynamically unstable with acute pelvic pain, activate surgical team immediately

Key Concepts

›PCS overview

›Chronic pelvic pain (CPP) from dilated, incompetent, refluxing pelvic veins

›Accounts for up to 30% of CPP cases

›Primarily premenopausal, multiparous women

›PCS is not an emergency diagnosis in most cases — acute presentations require excluding surgical emergencies first

›Ovarian torsion

›Ruptured ectopic

›Ruptured ovarian cyst

›Pelvic inflammatory disease with abscess

Alarm Features

›Cannot-miss diagnoses to exclude

›Acute onset severe pelvic pain — rule out ovarian torsion, ruptured ectopic, ruptured ovarian cyst

›Nausea and vomiting common with torsion

›Syncopal or presyncope with ruptured ectopic

›Fever with pelvic pain — rule out PID and tubo-ovarian abscess

›Cervical motion tenderness indicates PID

›Unilateral leg swelling with pelvic pain — consider iliac vein thrombosis (May-Thurner syndrome)

›Duplex ultrasound of lower extremity indicated

02History/hx73

Symptom Characterization

›Pain character

›Dull, aching unilateral or bilateral pelvic pain

›Occasional sharp flares superimposed

›Pelvic heaviness or pressure sensation

›Duration — chronic by definition, typically >6 months

›Onset often in reproductive years

›Often worsens with successive pregnancies

Aggravating and Relieving Factors

›Posture and activity triggers

›Prolonged standing or walking

›Characteristic feature of venous origin pain

›Hydrostatic pressure increases with upright posture

›Fatigue and end-of-day worsening

›Symptom pattern parallels chronic venous insufficiency

›Premenstrual exacerbation

›Estrogen peak promotes venous distensibility

›Relieving factors

›Lying supine relieves pain

›Distinguishes venous from somatic or inflammatory causes

›Elevation of legs reduces pelvic venous pressure

Sexual and Menstrual Symptoms

›Dyspareunia and postcoital symptoms

›Deep dyspareunia during intercourse

›Dilated pelvic veins engorge with pelvic congestion

›Prolonged postcoital ache — pathognomonic feature

›Distinguishes PCS from most other CPP causes

›Persists hours after intercourse

›Menstrual symptoms

›Dysmenorrhea

›Often worsens with time

›Premenstrual symptom flare

›Pain peaks days before menstruation

Associated Symptoms

›Urologic symptoms

›Dysuria and urinary frequency without infection

›Bladder irritability from adjacent venous congestion

›Sterile hematuria — associated with nutcracker syndrome variant

›Left renal vein compression by superior mesenteric artery

›Gastrointestinal symptoms

›Rectal discomfort and pressure

›Perineal varicosities contribute

›Bloating and constipation

›Constipation increases intra-abdominal pressure and worsens venous return

›Vascular symptoms

›Vulvar or perineal varicosities

›Visible at rest or after prolonged standing

›Atypical varicose veins — medial thigh, posterior thigh, buttock, perineum

›Distribution not explained by superficial saphenous insufficiency alone

Risk Factors

›Demographic and reproductive risk factors

›Multiparity — most significant risk factor

›Each pregnancy increases pelvic venous volume and valvular stress

›Premenopausal status required — estrogen-dependent condition

›History of varicose veins or chronic venous insufficiency

›Genetic predisposition to venous valve incompetence

›Connective tissue disorders

›Marfan syndrome, Ehlers-Danlos — weakened venous walls

›Occupational and anatomic risk factors

›Prolonged standing occupation

›Increases chronic venous hypertension

›Obesity

›Increases intra-abdominal pressure impairing venous return

›Anatomic variants

›Nutcracker syndrome — left renal vein compression between aorta and SMA

›May-Thurner syndrome — left common iliac vein compression by right common iliac artery

Past Medical and Surgical History

›Prior pelvic evaluation

›Previous negative laparoscopy for CPP in up to 50% of cases — PCS missed due to pneumoperitoneum

›CO2 insufflation compresses veins

›Trendelenburg positioning reduces pelvic venous filling

›Prior hysterectomy or oophorectomy history

›Post-hysterectomy PCS can persist if ovarian veins untreated

›Gynecologic conditions

›Endometriosis — can coexist with PCS

›Dysmenorrhea and dyspareunia overlap

›Fibroids or adenomyosis — assess for concurrent pathology

›History of DVT or venous thromboembolism

›May indicate underlying hypercoagulability or anatomic venous obstruction

03Physical Exam/exam45

Vital Signs

›Hemodynamic assessment

›Blood pressure — typically normal in PCS

›Hypotension suggests alternative acute diagnosis

›Temperature — typically afebrile

›Fever >38.0°C suggests PID, TOA, or other infectious etiology

›Heart rate — typically normal

›Tachycardia suggests acute pathology or significant pain

Abdominal Examination

›Ovarian point tenderness

›Junction of upper and middle thirds of line from umbilicus to ASIS

›Sensitivity 94% for venous-origin pelvic pain when combined with postcoital ache

›Specificity 77%

›Bilateral tenderness more common than unilateral

›Correlates with bilateral ovarian vein incompetence

›Peritoneal signs

›Absence of guarding and rigidity — favors PCS over surgical emergency

›Rebound tenderness mandates urgent surgical evaluation

›Bowel sounds — normal in PCS

Pelvic Examination

›Bimanual examination findings

›Adnexal tenderness — bilateral or left-predominant

›Cervical motion tenderness absent — distinguishes from PID

›Uterine tenderness on bimanual

›Enlarged or boggy uterus suggests adenomyosis

›Adnexal masses

›If present, prompt imaging to exclude ovarian pathology

›Speculum examination

04Differential Diagnosis/ddx50

Gynecologic Causes

›Endometriosis (N80.x)

›Dysmenorrhea, dyspareunia, infertility overlap with PCS

›Pain typically cyclical with menstruation

›Can coexist with PCS — both diagnoses may be present simultaneously

›Laparoscopy required for definitive diagnosis

›Adenomyosis (N80.0)

›Heavy menstrual bleeding, dysmenorrhea, diffusely enlarged uterus

›Junctional zone >12mm on MRI

›Absence of the postcoital ache pattern favors adenomyosis over PCS

›Ovarian cyst (N83.x)

›Functional cysts can cause pelvic pain with positional component

›Typically self-resolving

›Ultrasound differentiates

Surgical Emergencies (Cannot Miss)

›Ovarian torsion (N83.53)

›Acute severe unilateral pelvic pain with nausea and vomiting

›Absent venous flow on Doppler does not rule in; present flow does not rule out

›Surgical emergency — time to OR determines ovarian salvage

›Ruptured ectopic pregnancy (O00.x)

›Hemodynamic instability with pelvic pain and positive beta-hCG

›Empty uterus on ultrasound with free peritoneal fluid

›Immediate surgical consultation

›Tubo-ovarian abscess (N70.93)

›Fever, cervical motion tenderness, purulent discharge

›Elevated WBC and CRP

›IV antibiotics and consideration of drainage

05Laboratory Tests/lt36

Initial Exclusion Testing

›Urine pregnancy test (beta-hCG)

›Mandatory in all premenopausal women with pelvic pain

›Negative result required before attributing pain to PCS

›If positive, ectopic must be excluded with ultrasound

›Urinalysis and urine culture

›Sterile hematuria may support PCS or nutcracker syndrome variant

›Urinary tract infection excluded before attributing dysuria to PCS

›Microscopic hematuria without infection — consider renal vein compression imaging

Infection Markers

›Complete blood count

›Leukocytosis suggests infection or inflammatory process

›WBC >10 x10^9/L with pelvic pain warrants PID workup

›Anemia — assess for concurrent blood loss (fibroids, heavy menses)

›Inflammatory markers

›C-reactive protein (CRP)

›Elevated CRP supports infectious or inflammatory etiology over PCS

›Erythrocyte sedimentation rate (ESR)

›Non-specific but useful adjunct for inflammatory workup

›STI screening

›Gonorrhea and chlamydia NAAT (cervical or vaginal swab)

›Required when PID is in differential

›Negative result supports PCS over PID in appropriate context

Endocrine and Oncologic Testing

›CA-125

›If endometriosis or ovarian malignancy is suspected

›Elevated in endometriosis, ovarian cancer, fibroids, PID

08Treatment/t84

Conservative and Lifestyle Measures

›Non-pharmacologic interventions

›Posture modification

›Avoidance of prolonged standing

›Leg elevation periods during the day

›Compression therapy

›Graduated compression stockings may reduce venous pooling

›20-30 mmHg compression as starting point

›Exercise

›Regular low-impact activity improves venous return

›Avoid high-impact activities that increase intra-abdominal pressure acutely

Analgesic Therapy

›NSAIDs for symptomatic pain relief

›Ibuprofen 400-600 mg orally every 6-8 hours as needed

›With food to reduce GI effects

›Maximum 2400 mg/day

›Naproxen 250-500 mg orally twice daily

›Avoid in renal insufficiency and peptic ulcer disease

›NSAIDs provide symptomatic relief only; do not address underlying venous pathology

Venoactive Drug Therapy

›Micronized purified flavonoid fraction (MPFF)

›Diosmin 450 mg + hesperidin 50 mg per tablet — trade name Daflon

›Dose: 1000 mg (2 tablets of 500 mg) once daily

›Demonstrated QoL improvement and symptom severity reduction vs. placebo in RCT

›Mechanism

›Increases venous tone and reduces venous distensibility

›Anti-inflammatory and antioxidant effects on venous endothelium

›Reduces capillary permeability

›Safety

›Generally well tolerated

›GI upset most common side effect

›Use in pregnancy requires specialist guidance

Hormonal Suppression Therapy

›Medroxyprogesterone acetate (MPA)

›Dose: 30 mg orally daily for 6 months

›Mechanism — suppresses ovarian estrogen production

›Provides short-term symptom relief

›Limited long-term efficacy data

›Side effects

›Irregular bleeding, weight gain, mood changes

›Bone density loss with prolonged use

›Avoid estrogen-containing combined contraceptives — estrogen promotes venous distensibility and may worsen symptoms

›Superior to MPA in RCT for venographic improvement and symptom relief at 1 year

›Symptomatic improvement in up to 75% during therapy

›Add-back therapy required for treatment >6 months

›Continuous combined estrogen-progestogen add-back minimizes hypoestrogenic effects

›Bone density monitoring (DXA) at baseline and 12 months

›Limitations

›Side effects of hypoestrogenism — hot flashes, vaginal atrophy, reduced libido

›Symptoms often recur after stopping therapy

›Long-term data limited; hormonal therapies have unproven sustained efficacy

Interventional Treatment — Percutaneous Embolization

›Ovarian and pelvic vein embolization — mainstay definitive treatment

›Indications

›Confirmed PCS on imaging

›Permanent loss of fertility — extensive counseling required

09Special Populations/sp50

Pregnancy

›PCS in pregnancy

›Pelvic varicose veins are common and expected in pregnancy due to increased pelvic blood flow

›Not synonymous with PCS — symptoms in pregnancy differ from chronic PCS

›Pelvic varicosities often resolve or improve post-partum

›Avoid venography and embolization during pregnancy

›Ionizing radiation contraindicated

›Endovascular procedures deferred until post-partum

›Safe interventions in pregnancy

›MPFF — safety in pregnancy not established; generally avoid especially first trimester

›Compression garments — safe, reduce symptomatic pelvic and lower extremity congestion

›NSAIDs — avoid after 20 weeks gestation (premature ductus arteriosus closure risk)

›Acetaminophen 500-1000 mg every 6-8 hours preferred analgesic in pregnancy

›Post-partum management

›Reassess PCS symptoms after 6 months post-partum

›Many symptoms improve without intervention

›If symptoms persist post-partum and no further pregnancies planned, embolization can proceed

›Ovarian reserve implications should be discussed with women <30

Geriatric

›Post-menopausal presentations

›PCS is estrogen-dependent; symptoms often improve or resolve after menopause

›New onset pelvic pain with venous dilation in post-menopausal woman warrants malignancy exclusion

›Malignant venous obstruction mimics PCS on imaging

›Pelvic or abdominal malignancy causing extrinsic venous compression

›CT abdomen and pelvis with contrast for evaluation

›Hormonal therapy considerations in older women

›GnRH agonists not indicated post-menopause

›MPA — increased VTE risk in older women, especially with venous insufficiency

10Background/b67

Epidemiology

›Prevalence and disease burden

›PCS accounts for up to 30% of chronic pelvic pain cases in women

›CPP affects approximately 15-25% of reproductive-age women globally

›PCS significantly underdiagnosed due to non-specific symptoms and imaging overlap

›Case-control evidence

›Pelvic vein incompetence found in 62% of women with CPP vs. 19% of controls

›Odds ratio 6.79 (BJOG, 2023)

›Demographic distribution

›Predominantly premenopausal women

›Peak incidence in 3rd and 4th decades

›Multiparity is the strongest demographic risk factor

›Risk increases with each subsequent pregnancy

›Improvement or resolution common after menopause — estrogen-dependent condition

›Diagnostic delay

›Mean diagnostic delay of 5-7 years from symptom onset to PCS diagnosis

›Frequently attributed to psychiatric or psychosomatic causes

›Up to 50% of CPP investigations include negative laparoscopy

›PCS missed at laparoscopy due to pneumoperitoneum collapsing veins

Pathophysiology

›Venous anatomy and mechanism

›Ovarian veins drain the ovarian plexus

›Right ovarian vein drains into inferior vena cava

›Left ovarian vein drains into left renal vein

›Normally competent valves prevent retrograde flow

›Valve incompetence or agenesis leads to venous reflux

›Reflux increases pelvic venous hydrostatic pressure

›Estrogen contribution

›Estrogen promotes venous distensibility and weakens vein walls

›Explains predominance in premenopausal women and during pregnancy

›Exacerbation premenstrually when estrogen peaks

›Pregnancy causes sustained increase in pelvic blood flow

›Volume increase up to 60% above baseline

›Repeated pregnancies cumulatively damage venous valves

›Secondary causes of venous hypertension

›Nutcracker syndrome — left renal vein compression by SMA increases left ovarian vein pressure

›Causes left-sided PCS predominance and hematuria

›May-Thurner syndrome — left common iliac vein compression increases pelvic venous pressure bilaterally

›Risk of left iliac DVT

›Extrinsic compression from masses or malignancy in post-menopausal women

›Pain mechanism

›Pelvic venous congestion activates nociceptors in pelvic peritoneum

›Visceral pain radiates to pelvis, lower back, and perineum

›Postural pressure changes — upright posture increases venous hydrostatic pressure

›Explains relief with recumbency and worsening with standing

›Central sensitization contributes in chronic cases

›Coexisting anxiety and depression amplify pain perception

Therapeutic Considerations

›Treatment selection framework

›Etiologic classification before treatment

›Primary reflux (gonadal vein incompetence) — embolization is mainstay

›Secondary obstruction (May-Thurner, nutcracker) — treat obstruction first

›Mixed etiology — requires staged approach

›Severity-based stepwise approach

›Mild — lifestyle modification and venoactive drugs

›Moderate — add hormonal suppression if appropriate

›Severe — interventional embolization

›Evidence base for treatments

›Embolization has strongest evidence — systematic review of 12 studies showed sustained pain reduction

›Daniels et al., Journal of Vascular and Interventional Radiology, 2016

›Technical success 96-100%; symptom relief approximately 75%

›Hormonal therapy — short-term benefit only; symptoms recur after discontinuation

›RCT comparing goserelin to MPA: goserelin superior for venographic improvement at 1 year

›Soysal et al., Human Reproduction, 2001

›MPFF — placebo-controlled trial demonstrated QoL improvement and reduced symptom severity

›Akhmetzianov et al., Pain and Therapy, 2021

›ACOG position

›Evidence insufficient to establish definitive cause-and-effect between venous congestion and pain

›ACOG Practice Bulletin 218, Obstetrics and Gynecology, 2020

›PCS remains clinical-radiologic diagnosis requiring symptom correlation

11Patient Discharge Instructions/pdi37

copy discharge instructions

›What is Pelvic Congestion Syndrome?

›PCS is a cause of chronic pelvic pain from dilated, poorly draining veins in the pelvis

›Similar to varicose veins but located inside the pelvis

›More common in women who have had children

›Pain is typically dull and aching, worse after standing and better when lying down

›Your symptoms and treatment plan

›Your pain is caused by abnormally dilated veins in your pelvis that are not draining properly

›This is a chronic condition that requires ongoing management

›Several treatment options are available depending on severity

›Current treatment prescribed

›Take pain medication as prescribed — do not exceed the recommended dose

›Avoid prolonged standing when possible

›Elevate your legs when resting to reduce pelvic pressure

›Activity and lifestyle

›Modify daily activities to reduce time standing

›Take regular sitting or lying breaks if your job requires standing

›Wear graduated compression stockings if recommended by your doctor

›Put on in the morning before getting out of bed

›Regular low-impact exercise (walking, swimming) improves circulation

›Avoid heavy lifting or straining which increases abdominal pressure

›Follow-up instructions

›Return to your gynecologist or specialist as scheduled

›Symptom diary recommended — note pain triggers, severity (0-10 scale), and timing

›If referred for pelvic vein embolization, attend your pre-procedure appointment

›Bring imaging results and medication list to all appointments

›Return to emergency department immediately for

›Sudden severe pelvic pain significantly worse than your usual pain
