postoperative hematoma
Pronunciation: hee-mah-TOH-mah
Accumulation of blood in the surgical site following neurosurgical procedures, potentially requiring evacuation.
Full Definition
A postoperative hematoma is a collection of blood that accumulates at the surgical site following neurosurgical procedures. These hematomas can be epidural, subdural, or intraparenchymal depending on their location relative to brain structures. Postoperative hematomas may cause mass effect, increased intracranial pressure, and neurological deterioration, potentially requiring emergency surgical evacuation. Risk factors include coagulopathy, hypertension, and extensive surgical dissection. Early recognition through clinical monitoring and imaging is crucial for optimal patient outcomes.
Usage
Usage note: Specify location (epidural, subdural, intraparenchymal) and whether evacuation is required.
