What type of hemorrhage involves bleeding into the subgaleal compartment?

• A. Subgaleal hemorrhage
• B. Intracranial hemorrhage
• C. Retroperitoneal hemorrhage
• D. Intra-abdominal hemorrhage

Answer: (A)

Subgaleal hemorrhage refers specifically to bleeding in the subgaleal space, which is located beneath the galea aponeurotica—a strong fibrous tissue covering the skull. This type of hemorrhage is particularly significant in newborns and can occur due to various factors, often related to delivery practices such as the use of vacuum extraction, which can disrupt blood vessels and lead to bleeding in this area. The subgaleal compartment is unique in that it can accommodate a significant amount of blood, which may not be immediately apparent, making monitoring crucial following delivery. This type of hemorrhage can lead to complications if not managed properly, including significant blood loss and potential shock. In contrast to subgaleal hemorrhage, other types listed—such as intracranial hemorrhage, retroperitoneal hemorrhage, and intra-abdominal hemorrhage—pertain to bleeding in different anatomical locations and contexts. Intracranial hemorrhage occurs within the cranial cavity, while retroperitoneal and intra-abdominal hemorrhage involve bleeding in the abdominal cavity outside of the peritoneum. Each of these has distinct causes, presentations, and management strategies that do not relate directly to the subgaleal space.
