Summary
Unusual spinal hematomas after lumbar puncture can cause urinary retention and neurological deficits. This case highlights the importance of recognizing these rare complications in patients on anticoagulation.
Area of Science:
- Neurosurgery
- Urology
- Nephrology
Background:
- Lumbar punctures, while common diagnostic procedures, carry rare risks including spinal hematomas.
- Patients on anticoagulant therapy have an increased risk of bleeding complications.
Observation:
- A renal allograft recipient on anticoagulation developed urinary retention and S2-S4 neurological deficits post-lumbar puncture.
- Myelography revealed a posterior lumbosacral spinal canal defect.
Findings:
- Urodynamic testing indicated impaired parasympathetic and pudendal innervation.
- This suggests a neurological basis for the observed urinary dysfunction.
Implications:
- Early recognition and management of spinal hematomas are crucial in patients undergoing lumbar puncture, especially those on anticoagulation.
- Understanding the neuro-urological impact can guide treatment strategies for post-procedural complications.
