Does subgaleal hematoma cross suture lines?

Subgaleal hemorrhages cross suture lines and may enlarge after birth. Large subgaleal hemorrhages may lead to hypovolemic shock with a mortality rate of nearly 25%.

How does a cephalohematoma differ from subgaleal hematoma?

A subgaleal hematoma is caused by rupture of the emissary veins between the dural sinuses and scalp veins and is not bound by suture lines. Cephalohematomas generally do not pose a significant risk to the patient and resolve spontaneously. 1 Conversely, a subgaleal hematoma is a rare but more serious condition.

Does cephalohematoma cross midline?

In other words, a cephalohematoma is confined to the area on top of one of the cranial bones and does not cross the midline or the suture lines. Because the collection of blood is sitting on top of the skull and not under it, there is no pressure placed on the brain.

How long does a subgaleal hematoma last?

SGH may be misdiagnosed as cephalohematomas or caput succedaneum. ♣ Cephalhematoma is the collection of blood under the periosteum and does not cross the suture lines. Cephalhematomas are firm masses that will resolve in 2 weeks to 6 months.

Which is more common a cephalohematoma or A subgaleal hematoma?

Subgaleal hematomas may be ballotable and have a fluid wave. As noted previously, a cephalohematoma does not cross suture lines, whereas the other two may. Subgaleal hematomas are more common after assisted deliveries such as forceps and vacuum.

How does A subgaleal hematoma cross a suture line?

It therefore can cross suture lines and is a large potential space where hemorrhage can occur. Subgaleal hematomas usually occur due to shearing of emissary veins between the intracranial venous sinus and the scalp. A cephalohematoma is due to bleeding beneath the periosteum of the bone, i.e. between the periosteum and cortical bone.

Can a cephalohematoma cross a suture line?

Cephalohematomas are traumatic subperiosteal hematomas of the skull that are usually caused by birth injury. They are bound between the periosteum and cranium, and therefore cannot cross sutures. Being bound by a suture line distinguishes them from subgaleal hematoma, which can cross sutures.

How is a caput related to a cephalohematoma?

Caput is a subcutaneous collection of fluid that crosses the sutures and rapidly resolves hours to days after delivery. A cephalohematoma is a subperiosteal hemorrhage confined by suture lines. A subgaleal hemorrhage results from rupture of scalp veins.
