A vulvar hematoma is usually the consequence of a "straddle"
injury. When a woman falls while straddling a fixed structure, such as chair, railing,
sawhorse or fire hydrant, it is a common occurrence that the peri-clitoral vessels on one
side or the other will be crushed against the pubic bone. This results in a vulvar
hematoma.
Most of the vulvar enlargement is soft tissue swelling, but some is due to an
encapsulated hematoma.
Diagnosis is made on the basis of history of a fall and the typical physical findings
of unilateral swelling and pain.
Clinical management consists of:
- An icepack is placed over the perineum and left in place for 24-48 hours. This will help
control the pain and limit swelling and further bleeding into the hematoma.
- A Foley catheter is inserted and left in place. The local swelling may be sufficient to
impair voluntary voiding and the Foley is much easier to insert earlier in the process.
- Bedrest for several days to a week.
- Appropriate analgesia. Initially, this may need injectable narcotics. Later, oral
narcotics and then NSAIDs will give satisfactory results.
- Dramatic resolution will occur. When completely healed in a few weeks, the vulva will
look normal and function normally.
- Most of these hematomas will not require surgical exploration and drainage. If you
explore them, in about half the cases, no bleeding point will ever be found. Opening them
introduces bacteria into an otherwise sterile hematoma. Particularly in operational
settings, ice, Foley and bedrest are usually better choices for treatment.
- In following these, it may prove useful to measure the hematoma with a tape measure to
compare the size over time. As they are feeling less pain, patients will often feel that
the hematoma is enlarging. Having objective measures of its' size will be very reassuring
to the patient.
