[ References ](#references-heading) Postpartum hemorrhage is easy to miss when the uterus is firm and the blood on the pad does not look dramatic. The patient says the pain is unbearable, her pulse is climbing, and everyone keeps reaching for another uterotonic. That is how genital tract lacerations and concealed hematomas get missed. Trauma is a major PPH cause, and the bedside clue is simple: if bleeding continues with a firm uterus, look hard for trauma. [\[1\]](#cite-1 "Reference [1]") Start With the Pattern, Not the Procedure ----------------------------------------- If the placenta is complete, the fundus is firm, and bleeding persists, move trauma high on the differential. Risk rises after operative vaginal birth, episiotomy, macrosomia, prolonged or obstructed labor, and other deliveries that stretch or tear the lower genital tract. Do not let a reassuring fundal exam end the workup. [\[1\]](#cite-1 "Reference [1]") ### Hidden hemorrhage recognition Hematomas are where trainees get burned. Infralevator collections are often obvious, but paravaginal, supralevator, broad-ligament, and retroperitoneal bleeding may produce little external blood while the patient becomes tachycardic, anemic, and exquisitely uncomfortable. WHO teaching materials also flag a shock index greater than 1 as a warning sign during postpartum bleeding assessment. [\[2\]](#cite-2 "Reference [2]") Watch for these clues: - pain out of proportion to the visible laceration - vulvar or perineal swelling, ecchymosis, or a tense mass - deep pelvic or rectal pressure - urinary retention or difficulty voiding - falling hemoglobin or abnormal vital signs with modest visible bleeding Use this bedside frame: Lesion patternTypical cluesPractical implication**Infralevator** vulvar/lower vaginal hematomavisible swelling, ecchymosis, severe vulvar/perineal painexam is often diagnostic**Supralevator/paravaginal** hematomalittle external finding, deep pelvic or rectal pressure, anemia, instabilitythink occult hemorrhage; imaging may help if stable**Broad ligament/retroperitoneal** extensionabdominal distension, shock, sometimes hematuriaurgent senior escalation That distinction matters because supralevator bleeding is the classic “hidden hemorrhage” lesion. [\[2\]](#cite-2 "Reference [2]") Repair Principles That Prevent Rebleeding ----------------------------------------- Repair is not a quick stitch at the introitus. Adequate anesthesia, exposure, lighting, suction, retractors, and an assistant are prerequisites, and actively bleeding vessels should be clamped or compressed before repair. If you cannot see the apex, you are not ready to close. [\[3\]](#cite-3 "Reference [3]") ### What good repair looks like - Re-examine the **entire** genital tract, not just the obvious tear. - For cervical injury, inspect the full circumference with sponge forceps moved sequentially around the cervix. - Put the first stitch **above the apex** of the tear; otherwise the retracted vessel keeps bleeding. - Repair deep vaginal tears in layers: close the deep layer first, then the mucosa. - Protect nearby structures. Posterior repairs must respect the rectum; anterior or lateral tears should make you think about urethral or bladder involvement. - Reassess hemostasis before you leave. Persistent oozing means the source or the space is not controlled. [\[3\]](#cite-3 "Reference [3]") A prevention pearl: after an operative vaginal delivery or any difficult repair, do a deliberate final inspection before you declare victory. Missing the high sulcal or cervical extension is far more dangerous than taking one extra minute to look. [\[1\]](#cite-1 "Reference [1]") > **Clinical Pearl:** A repaired perineum does **not** exclude trauma. The missed lesion is often higher—cervix, deep sulcus, or paravaginal space. When to Image and When to Move to the OR ---------------------------------------- Do not delay repair of an obvious bleeding laceration for imaging. Imaging is for the stable patient whose source is unclear, whose symptoms exceed the visible findings, or in whom you suspect a deep hematoma, retroperitoneal extension, uterine rupture, or vascular lesion. In current ACR guidance, pelvic ultrasound is usually appropriate first-line imaging for postpartum hemorrhage, while CT or CTA becomes useful when active occult bleeding must be localized. [\[4\]](#cite-4 "Reference [4]") ### Practical imaging strategy 1. **Exam first** for visible vulvar, vaginal, perineal, or cervical trauma. 2. **Ultrasound first** in stable PPH when the diagnosis is uncertain. 3. **MRI** can help localize deep-seated pelvic hematomas after difficult vaginal delivery when no large palpable hematoma is found. 4. **CT/CTA** is the better escalation when you suspect active extravasation, retroperitoneal spread, or another occult surgical source. [\[4\]](#cite-4 "Reference [4]") ### OR or senior consult now Move early to the OR, senior obstetric help, and anesthesia when exposure is poor, the tear extends high into the vagina or cervix, the hematoma is expanding, vitals are abnormal, or bedside repair is failing. If bleeding persists from a cervical tear that cannot be repaired transvaginally, or if an arterial source is suspected, selective arterial embolization is a reasonable fertility-sparing option where available. [\[3\]](#cite-3 "Reference [3]") Key Takeaways ------------- - A **firm uterus plus ongoing bleeding** is trauma until proven otherwise. - Severe postpartum pelvic, vulvar, or rectal pain is not “just normal soreness.” Exclude hematoma. - Find the apex before you suture, and repair deep tears in layers. - Stable but unclear source: image thoughtfully. Unstable or expanding: escalate to OR. - After repair, reassess vitals, bleeding, and pain. If the physiology still looks wrong, keep looking. [\[1\]](#cite-1 "Reference [1]") The board answer is straightforward, but the clinical lesson is sharper: genital tract trauma causes PPH by hiding in plain sight. Inspect systematically, respect disproportionate pain, and escalate earlier than your ego wants to. That is how you prevent a missed hemorrhage. [\[1\]](#cite-1 "Reference [1]") Frequently Asked Questions ---------------------------- ### What is the classic clue that postpartum bleeding is from trauma rather than uterine atony? Persistent bleeding with a **firm uterus** and a complete placenta should push genital tract trauma high on the differential. Look for cervical, vaginal, vulvar, or perineal injury rather than reflexively giving more uterotonics. [\[1\]](#cite-1 "Reference [1]") ### When should I suspect a concealed postpartum hematoma? Suspect it when pain is disproportionate, the patient has rectal or pelvic pressure, urinary retention, tachycardia, anemia, or shock with surprisingly little visible bleeding. Supralevator and paravaginal hematomas are the classic occult lesions. [\[2\]](#cite-2 "Reference [2]") ### When is imaging most helpful in genital tract hematomas? Imaging helps most in **hemodynamically stable** patients when the bleeding source is unclear or a deep hematoma is suspected. Ultrasound is usually first-line; MRI can localize deep pelvic hematomas, and CT/CTA is useful when active occult bleeding is suspected. [\[4\]](#cite-4 "Reference [4]") ### When is conservative management reasonable for a postpartum genital hematoma? Only in a stable patient with a small or nonexpanding hematoma, controlled symptoms, and close reassessment. Expansion, worsening pain, anemia, or abnormal vitals should trigger drainage, surgery, or embolization rather than watchful waiting. [\[5\]](#cite-5 "Reference [5]") ### When should interventional radiology be involved? Call IR when bleeding persists despite repair, when a cervical tear cannot be repaired transvaginally, or when an arterial source or deep pelvic hematoma is suspected and the patient is stable enough for embolization.
