Summary
A patient developed persistent lower limb weakness after spinal anesthesia for bladder surgery. This rare neurologic deficit was likely caused by spinal anesthesia complications, not surgical issues.
Area of Science:
- Neurology
- Anesthesiology
- Urology
Background:
- Prostatic cancer extending to the urinary bladder requires surgical intervention.
- Transurethral resection of the bladder neck is a common procedure for such cases.
- Spinal anesthesia is frequently employed for lower abdominal and urologic surgeries.
Observation:
- A 70-year-old man experienced proximal lower limb weakness hours after transurethral resection of the bladder neck under spinal anesthesia.
- The neurological deficit persisted for several months.
- No local surgical complications or metastatic disease were identified as causes.
Findings:
- The patient's persistent lower limb weakness was considered likely related to spinal anesthesia.
- Potential causes of neurologic deficits post-spinal anesthesia include direct nerve injury, hematoma, abscess, arachnoiditis, neurotoxicity, or spinal cord ischemia.
- Spinal cord ischemia can be precipitated by patient positioning, hypotension, or vasoconstrictors during surgery.
Implications:
- Highlights the importance of considering spinal anesthesia as a potential cause of rare neurologic deficits.
- Underscores the need for vigilance regarding potential complications of spinal anesthesia, even in the absence of obvious surgical issues.
- Suggests further investigation into the mechanisms and prevention of spinal anesthesia-related neurologic complications.
