A rare but serious complication of regional anesthesia, subdural hemorrhage (SDH), can cause persistent positional headaches. Prompt diagnosis and surgical intervention are crucial for potentially fatal subdural hematoma cases.
Area of Science:
- Anesthesiology
- Neurosurgery
- Neurology
Background:
- Regional anesthesia is frequently employed for surgical procedures.
- Postdural puncture headache (PDPH) is a common, typically self-limiting complication.
- Subdural hemorrhage (SDH) is a rare but life-threatening complication that requires immediate recognition.
Purpose of the Study:
- To highlight a case of subdural hematoma presenting as a persistent positional headache after regional anesthesia.
- To emphasize the importance of considering SDH in the differential diagnosis of headaches post-anesthesia.
- To underscore the critical need for timely surgical intervention in cases of SDH.
Main Methods:
- Case report of a healthy female patient experiencing persistent positional headache.
- Diagnostic workup including neuroimaging to identify the cause of headache.
- Surgical evacuation of the identified subdural hematoma.
Main Results:
- The patient presented with symptoms mimicking PDPH but was diagnosed with a large subdural hematoma.
- The subdural hematoma caused a significant midline shift, necessitating urgent surgical management.
- Surgical evacuation of the hematoma was performed.
Conclusions:
- Persistent positional headaches following regional anesthesia can be indicative of serious intracranial pathology like SDH.
- Early diagnosis and surgical decompression are vital for managing SDH and improving patient outcomes.
- Anesthesiologists and neurologists must maintain a high index of suspicion for SDH in patients with persistent headaches post-regional anesthesia.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
