A vaginal hematoma is a collection of blood that forms within the soft tissues of the vaginal wall, vulva, or the surrounding pelvic space, usually after tissue injury or blood vessel damage. Most cases arise after childbirth, but the condition can also follow accidental injuries, surgery, or sexual intercourse. Depending on its size and location, a vaginal hematoma can range from a small, self-limiting bruise to a rapidly expanding mass that threatens hemodynamic stability and requires urgent intervention.
How Vaginal Hematomas Form
The vaginal and vulvar tissues are richly supplied with blood vessels. When one or more of these vessels tears or ruptures, blood leaks into the surrounding connective tissue. Because there is no open wound for the blood to escape through, it pools and creates a pressurized pocket. In many postpartum cases, the bleeding comes from veins rather than arteries, and the damaged vessel cannot always be pinpointed even during surgery because the bleeding originates from multiple small sites rather than a single identifiable source.1Obstetrics and Gynaecology Cases – Reviews. Endovascular Management of Refractory Puerperal Hematomas: A Case Report and Review of the Literature
The tissue planes of the pelvis allow blood to track in several directions. A hematoma that starts near the vaginal wall can extend downward into the vulva, upward into the broad ligament, or even behind the peritoneum. This ability to spread through tissue layers is part of what makes larger hematomas dangerous: the visible swelling may underrepresent the true volume of blood loss.
Obstetric Causes
Childbirth is by far the most common setting for vaginal hematomas. The vaginal tissues stretch enormously during delivery, and small vessels can tear even in an otherwise uncomplicated birth. The risk rises substantially when instruments are used. Deliveries involving the sequential use of a vacuum extractor followed by forceps carry a roughly six-fold higher rate of hematoma among women who have given birth before, compared with spontaneous vaginal deliveries.2American Journal of Obstetrics and Gynecology. The effect of sequential use of vacuum and forceps for assisted vaginal delivery on neonatal and maternal outcomes That same study found elevated rates of severe lacerations and postpartum hemorrhage with sequential instrument use, underscoring the cumulative trauma that operative vaginal delivery can cause.
Episiotomy, prolonged second stage of labor, and large birth weight are other recognized contributors. In some cases, a hematoma develops even when the delivery appeared straightforward. A blood vessel deep in the vaginal wall can tear without any visible laceration on the surface, which is one reason postpartum hematomas sometimes go undetected for hours.
Non-Obstetric Causes
Outside of childbirth, vulvar and vaginal hematomas occur after blunt trauma to the genital area. A common mechanism is the straddle injury, where a fall onto a narrow object like a bicycle crossbar, playground equipment, or a fence concentrates force directly on the vulva. In a review of pediatric and adolescent cases, every premenarchal patient who presented with a vulvar hematoma had sustained a straddle injury. Among older adolescents who had reached menarche, the causes were more varied and included consensual sexual intercourse and prior vulvar surgery.3Journal of Pediatric and Adolescent Gynecology. Management of Traumatic Vulvar Hematomas in Pediatric and Adolescent Females
Genital injuries from any cause can affect the labia, vulva, vagina, urethra, and surrounding structures. When these injuries are not properly managed, they can lead to chronic discomfort, pain during intercourse, or, in rarer cases, fistula formation.4Elsevier / PubMed Central. Genital injuries acute evaluation and management Anticoagulant medication and bleeding disorders can also predispose someone to hematoma formation after relatively minor trauma that would not normally cause significant bleeding.
Symptoms and How Location Changes the Picture
The symptoms you experience depend heavily on where the hematoma sits relative to the pelvic floor muscles. The levator ani muscle group acts as a dividing line. A hematoma below that muscular plate, in the vulva or lower vagina, typically produces visible swelling, pain, bruising of the skin, and sometimes difficulty urinating. These are the hematomas that you or a clinician can see and feel. A hematoma above the levator plate, deeper in the pelvis, may produce no external signs at all.5PubMed Central. Paravaginal hematomas; their recognition and management postpartum
That distinction matters enormously for detection. A postpartum patient with a supralevator hematoma may have unexplained tachycardia, falling blood pressure, or worsening pain without any obvious swelling. Because the blood is collecting in a space hidden from external view, clinicians sometimes identify the problem only once the patient shows signs of significant blood loss. Urinary retention is a common early clue in either location, because the expanding mass compresses the urethra or bladder.
Diagnosis
For a hematoma in the vulva or lower vagina, the diagnosis is usually straightforward on physical examination. The area is visibly swollen, tense, and discolored, and the mass is tender to the touch. The more difficult diagnostic challenge involves hematomas that extend above the pelvic floor or that develop deep within the paravaginal tissue without obvious external findings.
Imaging plays a key role in those cases. Ultrasound is generally the first-line tool, and it can be performed transabdominally with a full bladder or transperineally to visualize paravaginal collections after vaginal delivery. CT scanning and MRI are particularly helpful for hematomas above the pelvic diaphragm and for assessing how far the blood has tracked into the pelvis. When CT is performed with intravenous contrast, it can also identify arteriovenous malformations or retroperitoneal bleeding, though these are uncommon causes of postpartum hematoma.6Clinical Case Reports Journal. Conservative Management of Large Spontaneous Vaginal Hematoma in the Puerperium Ultrasound is generally preferred as the initial imaging approach for patients with unexplained postpartum pelvic pain, vulvar swelling, or urinary retention.
Conservative Management
Not every vaginal hematoma needs surgery. Small, stable hematomas are often managed with pressure, ice packs, pain relief, and close monitoring.7Obstetrics and Gynaecology Cases – Reviews. Endovascular Management of Refractory Puerperal Hematomas: A Case Report and Review of the Literature The body gradually reabsorbs the pooled blood over days to weeks, much like a deep bruise. During this time, the swelling and discoloration slowly resolve, though the area may remain tender for a while.
Conservative management works best when the hematoma is not expanding, the patient is hemodynamically stable, and pain is controlled with standard analgesics. Close surveillance is the critical part: serial assessments of the size of the mass, vital signs, and hemoglobin levels help clinicians detect any progression early. If the hematoma continues to grow, the pain becomes unmanageable, or vital signs begin to deteriorate, the plan shifts to intervention.
Surgical Treatment
Surgery is indicated when a hematoma is large, expanding rapidly, or not responding to conservative measures. The standard approach involves making an incision over the most prominent part of the swelling, evacuating the clotted blood, and attempting to identify and tie off any bleeding vessel. In practice, a single bleeder often cannot be found, because the hemorrhage tends to be diffuse and venous.8Obstetrics and Gynaecology Cases – Reviews. Endovascular Management of Refractory Puerperal Hematomas: A Case Report and Review of the Literature In those situations, the cavity may be packed or sutured closed to apply pressure and tamponade the bleeding.
In one reported non-obstetric case, a large vulvar hematoma required evacuation under spinal anesthesia. A vertical incision over the most prominent area released more than 500 milliliters of clotted blood, and the resulting cavity was closed with interrupted sutures without packing or drainage.9Journal of Case Reports and Images in Obstetrics and Gynecology. Surgical management of a large non-obstetric vulvar hematoma: A case report Cosmetic concerns are real for many patients. In one case, the surgical team chose to make the incision through the vaginal sidewall rather than the external vulvar skin so the scar would be hidden. After evacuating the blood and achieving hemostasis, the wound edges were secured in a technique resembling marsupialization to allow continued drainage.10PubMed Central. Evacuation of a large traumatic vulvar haematoma with an intravaginal cosmetic approach These cases highlight that the specific surgical approach can be tailored to the patient’s anatomy and preferences.
When Surgery Is Not Enough
Sometimes surgical evacuation fails to control the bleeding, or the patient is too unstable to tolerate a prolonged operation. Puerperal hematoma is considered one of the life-threatening obstetric emergencies, and ligating the bleeding vessel surgically is not always feasible in a hemodynamically unstable patient.11PubMed Central. Angiographic Embolization in the Treatment of Puerperal Hematoma In those cases, interventional radiology offers an alternative: pelvic arterial angiography and embolization. A catheter is threaded through an artery in the groin to the pelvic blood supply, and the feeding vessel is blocked with tiny particles or coils. The procedure is minimally invasive and can be performed under local anesthesia with sedation.
A study comparing transcatheter arterial embolization with surgical management for postpartum vulvovaginal hematomas found that embolization reduced the total amount of blood transfusion required compared with surgery.12American Journal of Obstetrics & Gynecology. Transcatheter arterial embolization outperforms surgery in reducing blood transfusions for postpartum vulvovaginal hematoma This finding has made embolization an increasingly preferred first-line option for refractory hematomas, particularly in patients who have already undergone one unsuccessful attempt at surgical control or who are continuing to bleed despite packing.
What Predicts Who Will Need Surgery
Clinicians have looked at whether certain factors can help predict which postpartum hematomas will require surgical drainage versus which will resolve on their own. Research into clinical predictors of postpartum vaginal and vulvar hematomas has found that postpartum hemorrhage rates and blood transfusion needs did not consistently differ between groups managed conservatively and those who went to surgery, which means the decision to operate often comes down to the trajectory of the individual case rather than a simple threshold.13PubMed Central. Clinical predictors of postpartum vaginal and vulvar hematomas and the need for surgical treatment In practical terms, this means that a “wait and watch” approach with frequent reassessment remains the standard starting point, with the pivot to intervention guided by how the patient is responding rather than by a single lab value or measurement.
Reducing the Risk During Childbirth
Because vaginal hematomas share many risk factors with perineal lacerations and other birth-related soft tissue injuries, the same strategies that reduce tearing also lower hematoma risk. Evidence supports several approaches for reducing genital tract trauma during spontaneous vaginal birth:
- Perineal massage: Done in the weeks before delivery, this reduces injury rates for first-time mothers.
- Upright or lateral positions: Birthing in positions other than flat on the back distributes pressure more evenly across the perineum.
- Avoiding forced pushing: Letting the body push reflexively, rather than prolonged breath-holding, reduces the intensity of pressure on vaginal tissues.
- Delayed pushing with epidural: Waiting to push until the urge is strong, rather than pushing immediately at full dilation, is associated with less trauma.
- Avoiding routine episiotomy: Episiotomy can itself create the tissue disruption that leads to hematoma.
- Controlled delivery of the head: Guiding the baby’s head slowly through the perineum lets tissues stretch gradually.
These measures do not eliminate the possibility of hematoma entirely, but they meaningfully lower the odds of the kind of tissue damage that leads to bleeding into the vaginal and vulvar tissues.14PubMed. Minimizing genital tract trauma and related pain following spontaneous vaginal birth
Vaginal Hematomas in Children and Adolescents
Vulvar hematomas in younger patients present a distinct clinical challenge. The mechanism is almost always accidental in prepubertal girls, with straddle injuries accounting for every case in one series of premenarchal patients.15Journal of Pediatric and Adolescent Gynecology. Management of Traumatic Vulvar Hematomas in Pediatric and Adolescent Females These injuries typically happen during play, cycling, or falls where the child lands with force on a narrow surface.
The genital tissues of prepubertal girls are thinner and less estrogenized than in adults, which means they are more vulnerable to bruising but also that small hematomas can look alarming relative to the child’s body size. Clinicians evaluate these injuries carefully, both to manage the hematoma and to assess whether the injury is consistent with the reported mechanism. The good news is that most childhood vulvar hematomas are small and respond to conservative care: ice, rest, and pain management. Surgical drainage is reserved for large or expanding collections, just as in adults.
Adolescents who have reached menarche have a broader range of causes, including sexual intercourse and prior surgical procedures, which means the clinical history is especially important in guiding evaluation and ensuring appropriate follow-up care.
Why Some Hematomas Recur or Become Complicated
Most vaginal hematomas resolve completely, but complications do occur. If a hematoma is inadequately drained or if the underlying vessel continues to ooze, the collection can reform. Infection is another risk, particularly when the hematoma is large or when surgical evacuation has been performed. An infected hematoma may present with worsening pain, fever, and purulent discharge, and it typically requires drainage combined with antibiotics.
Abscess formation is the most common infectious complication. The stagnant blood inside a hematoma provides a good environment for bacteria, especially in the warm, moist genital area. For this reason, clinicians watch closely for signs of infection in the days following either conservative or surgical management. Hematomas that extend deep into the pelvis carry additional risks because of their proximity to the bladder, ureters, and rectum, and because the blood can track into the retroperitoneal space where it is harder to monitor and manage.
Rarely, a large or poorly managed genital injury can lead to long-term consequences including chronic pain, scar tissue that causes discomfort during intercourse, or fistula formation.16Elsevier / PubMed Central. Genital injuries acute evaluation and management These outcomes are uncommon when the initial injury is recognized and treated promptly, which is why the emphasis on early detection and appropriate follow-up runs through every aspect of hematoma management.
What Recovery Actually Looks Like
For a small hematoma managed conservatively, you can expect the swelling and discoloration to peak within the first day or two and then gradually diminish over one to three weeks. The area may remain tender, and sitting or walking can be uncomfortable during the first week. Ice packs, sitz baths, and over-the-counter pain relievers are typically sufficient for comfort during this phase.
After surgical evacuation, recovery depends on the size of the original hematoma and whether packing was placed. Vaginal packing, if used, is usually removed within 24 to 48 hours. You may have a urinary catheter for a short period if the hematoma was compressing the urethra. Most patients who undergo evacuation of a straightforward hematoma are discharged within a day or two of the procedure, with instructions to watch for signs of re-accumulation or infection: increasing pain, new swelling, fever, or foul-smelling discharge.
Patients who required arterial embolization generally recover faster from the procedure itself, since it avoids a surgical incision in an already traumatized area. However, the underlying tissue still needs time to heal, and the bruised, swollen feeling persists for a similar duration. Activity restrictions typically apply for several weeks regardless of the treatment method, with a gradual return to normal as comfort allows. Sexual activity is usually deferred until pain has resolved and any incisions have healed, which your clinician can help you gauge at a follow-up visit.
