If a patient is bleeding at the surgical site after a lumbar laminectomy and requires a return to the OR, what complication should the surgeon suspect if not resolved immediately?

In the scenario where a patient is bleeding at the surgical site after a lumbar laminectomy, the concern for a hematoma arises if the bleeding is not addressed promptly. A hematoma is a localized collection of blood outside of blood vessels, which can occur due to the accumulation of blood at the surgical site as a result of uncontrolled bleeding.

This can pose several risks, including increased pressure on surrounding tissues, which may lead to complications such as nerve compression or infection. If a hematoma is significant and not resolved, it may require surgical intervention to evacuate the blood and control the source of bleeding.

In the context of lumbar laminectomy, which involves manipulation around the spine, the formation of a hematoma could severely compromise recovery and lead to further complications if not managed quickly. Thus, the presence of bleeding that necessitates a return to the operating room signifies a high alert for the potential development of a hematoma.
