Subgaleal hemorrhage

Subgaleal Hemorrhage

Subgaleal hemorrhage (pronunciation: sub-ga-le-al hem-or-rage) is a rare but potentially life-threatening condition that involves bleeding into the subgaleal space, a potential space between the galea aponeurotica and the periosteum of the skull.

Etymology

The term "subgaleal hemorrhage" is derived from the Latin "sub" meaning under, "galea" meaning helmet, and "hemorrhage" from the Greek "haima" meaning blood and "rhegnynai" meaning to burst forth. Thus, it literally means bleeding under the helmet, referring to the galea aponeurotica that covers the skull like a helmet.

Causes

Subgaleal hemorrhage is most commonly associated with trauma to the head, particularly in newborns during difficult birth procedures such as vacuum-assisted deliveries. Other causes can include coagulation disorders, scalp lacerations, and skull fractures.

Symptoms

Symptoms of subgaleal hemorrhage can include swelling of the scalp, pallor, tachycardia, and hypotension. In severe cases, it can lead to shock and death if not promptly treated.

Treatment

Treatment of subgaleal hemorrhage involves addressing the underlying cause of the bleeding, managing the patient's hemodynamic status, and in some cases, surgical intervention to evacuate the blood.
