›Underestimation of blood loss due to concealed retroperitoneal extension

›Failure to recognize spontaneous hematoma without obvious trauma in anticoagulated or pregnant patients

›Misidentification as Bartholin abscess delaying hemorrhage control

02History/hx41

Mechanism of Injury

›Sexual intercourse or consensual genital trauma

›Sexual assault (requires SANE evaluation and forensic documentation)

›Vulvar surgery or procedural complication

Symptom Characterization

›Pain and swelling profile

›Acute onset unilateral vulvar or perineal pain

›Pressure sensation or fullness in perineum or rectum

›Rapid enlargement of swelling suggesting active arterial bleeding

›Preeclampsia and thrombocytopenia

03Physical Exam/exam18

Vital Signs and Hemodynamic Assessment

›Hemodynamic parameters

›Heart rate and blood pressure with shock index calculation (HR/SBP)

›Orthostatic vital signs if able to assess volume depletion

External Genital Examination

›Vulvar and labial inspection

›Unilateral labial or vulvar swelling with ecchymosis

›Tense fluctuant mass with dimensions documented (cm)

›Rapid expansion on serial exams indicating active bleeding

05Laboratory Tests/lt17

Hematologic Studies

›Complete blood count

›Serial hemoglobin and hematocrit for monitoring progressive anemia from occult bleeding

›Platelet count to assess for thrombocytopenia contributing to hematoma

›Transfusion required in up to 73% of puerperal cases requiring surgical management

Type and Crossmatch

›Urinalysis with microscopy for hematuria indicating urethral or bladder injury

06Diagnostic Tests/dt29

Scoring Systems

›Severity stratification tools

›Shock index (HR/SBP) as primary hemodynamic scoring tool

›Shock index > 1.0 indicates hemodynamically significant hemorrhage

›Shock index > 1.5 triggers massive transfusion protocol consideration

›Hematoma size thresholds for management decisions

›Less than 3 cm in premenarchal patients: conservative management appropriate

›Less than 6 cm in postmenarchal patients: conservative management appropriate

›Greater than 5 cm per ACS Best Practices Guidelines: surgical intervention indicated

›Presence of extravasation on CT: adjusted relative risk 5.30 for need for therapeutic intervention

MRI

›MRI indications and findings

›Detailed anatomic mapping of hematoma extent and retroperitoneal involvement

›T1 hyperintense signal confirms subacute blood products

›T2 signal characteristics distinguish hematoma from solid mass or abscess

›Not typically first-line in acute setting due to time constraints

›Preferred for follow-up imaging after conservative management or surgical repair

›CT with intravenous contrast indications

›Gold standard for large or expanding hematomas requiring intervention planning

›Active extravasation on CT angiography is the only significant predictor of need for therapeutic intervention (aRR 5.30)

›Identification of retroperitoneal extension beyond vulvar compartment

›Hematoma volume quantification for serial comparison

›CT angiography identifies pudendal, inferior gluteal, or internal iliac artery branch bleeding

›Recommended for any hematoma with hemodynamic instability or rapidly expanding presentation

Ultrasound

›Ultrasound applications

›Transperineal ultrasound as first-line imaging for characterizing hematoma size and location

07Disposition/dispo19

Admission Criteria

08Treatment/t40

Conservative Management

›Non-operative treatment (stable, non-expanding hematomas without extravasation)

›Ice packs to perineum for first 24 hours (20 minutes on, 20 minutes off)

›Reduces swelling and provides analgesia

›Transition to sitz baths after acute phase

›Compression dressing or snug perineal pad

›Foley catheter for urinary retention

›Relieves urethral obstruction from hematoma compression

›Maintains until hematoma begins to resolve and voiding is possible

›Hematomas without extravasation on CT can be managed conservatively regardless of size (Takahashi et al, AJOG 2024)

Analgesia

›Pain management protocol

›Acetaminophen 650 to 1000 mg oral every 6 hours (preferred first-line)

›Maximum 4000 mg per 24 hours (3000 mg per 24 hours in hepatic impairment)

›Ibuprofen 400 to 600 mg oral every 6 to 8 hours if no active bleeding concern

›Avoid if large hematoma or coagulopathy present

›Oxycodone 5 to 10 mg oral every 4 to 6 hours for moderate to severe pain

›Ketorolac 15 to 30 mg IV every 6 hours (short-term, maximum 5 days; avoid if bleeding active)

Surgical Intervention

›Operative management (rapidly expanding, hemodynamically significant, or > 5 cm per ACS guidelines)

›Incision and drainage with clot evacuation

›Incision over point of maximal fluctuance

›Identify and ligate discrete bleeding vessels with absorbable suture

›If no discrete vessel identified, suture-obliterate cavity and pack

›Closed-system drainage (Jackson-Pratt drain) placement to reduce reaccumulation

›Examination under anesthesia for inaccessible vaginal or high perineal extension

›Broad-spectrum antibiotics if surgical evacuation performed

›Cefazolin 2 g IV (3 g if weight > 120 kg) within 60 minutes of incision

09Special Populations/sp22

Pregnancy

›Antepartum and intrapartum considerations

›Spontaneous vulvar hematoma without trauma possible due to increased pelvic vascularity

›Venous engorgement of pelvic vasculature in pregnancy increases hematoma severity

›Serial fetal heart rate monitoring required during maternal hemorrhage

›MRI preferred over CT for imaging when fetal radiation exposure is a concern

›Avoid NSAIDs after 20 weeks gestation (risk of premature ductal closure and oligohydramnios)

›TAE feasible in pregnancy; uterine and ovarian artery shielding employed when possible

Geriatric

›Older adult considerations

›Higher prevalence of anticoagulant use (warfarin, direct oral anticoagulants) increasing hematoma risk and severity

›Anticoagulant reversal: vitamin K 5 to 10 mg IV for warfarin; andexanet alfa or 4-factor PCC for factor Xa inhibitors

›Reduced physiologic reserve for hemorrhage; earlier transfusion threshold

›Atrophic vulvar and vaginal tissue more susceptible to injury from minor trauma

›Spontaneous hematoma may indicate underlying pelvic malignancy requiring follow-up imaging

Pediatrics

›Premenarchal and adolescent considerations

›Straddle injury is most common mechanism in premenarchal girls

›Lacerations present in up to 50% of premenarchal patients with vulvar hematoma

›Conservative management appropriate for hematomas less than 3 cm without expansion

›Examination under anesthesia required for complete assessment when exam is not tolerated or sexual abuse suspected

›Screen for sexual abuse; involve child protective services and SANE nurse if suspected

›Avoid pelvic exam without adequate analgesia or sedation in young children

›Acetaminophen 15 mg/kg oral every 6 hours (maximum 1000 mg per dose)

›Ibuprofen 10 mg/kg oral every 6 to 8 hours (maximum 400 mg per dose) if no active bleeding

10Background/b21

Epidemiology

›Incidence and prevalence data

›Puerperal vulvovaginal hematoma incidence approximately 1 to 2 per 1000 vaginal deliveries

›Non-obstetric vulvar hematoma incidence approximately 3.7% of vulvar trauma presentations

›Operative vaginal delivery (forceps or vacuum) is the strongest obstetric risk factor

›Straddle injury accounts for the majority of non-obstetric vulvar hematomas in all age groups

›Transfusion required in up to 73% of puerperal cases requiring surgical management

›Expected resolution time: approximately 3 weeks conservative; approximately 9 days surgical

Pathophysiology

›Mechanisms of hematoma formation

›Rich bilateral vulvar vascular network from pudendal, inferior gluteal, and obturator artery branches

›Vulvar venous plexus lacks venous valves, predisposing to rapid hematoma expansion

›Bleeding is predominantly venous in origin; arterial bleeding causes rapidly expanding or life-threatening hematoma

›Hematoma forms within loose connective tissue of the labia majora, ischiorectal fossa, or paravaginal space

›Retroperitoneal extension occurs when hematoma dissects along fascial planes above levator ani

›Spontaneous hematoma in pregnancy reflects increased pelvic vascularity and venous hypertension

Therapeutic Considerations

›Evidence base for management decisions

›Presence of active extravasation on CT is the only significant predictor of need for therapeutic intervention (adjusted relative risk 5.30) (Takahashi et al, AJOG 2024)

›TAE outperforms surgery in reducing blood transfusions for postpartum vulvovaginal hematoma (Takahashi et al, AJOG 2024)

›Conservative management appropriate for hematomas without CT extravasation regardless of absolute size

›ACOG Practice Bulletin No. 183 (2017) addresses postpartum hemorrhage management including genital tract hematoma

›ACS Best Practices Guidelines for Genitourinary Injuries (2025) recommend intervention for hematomas > 5 cm

›Closed-system drainage reduces hematoma reaccumulation after surgical evacuation (Zahn et al, J Reprod Med 1996)

11Patient Discharge Instructions/pdi17

copy discharge instructions
