Cisternal puncture complications. Treatment of coccidioidal meningitis with amphotericin B
Abstract:
Of two patients who had acute neurologic damage from cisternal punctures, one died 17 hours following a tap which produced major subarachnoid hemorrhage, the other patient recovered from probable brain stem infarction associated with cisterna magna amphotericin injection. Subarachnoid hemorrhage is the commonest major complication of cisternal puncture, with at least 30 reported fatalities. Other serious complications result from direct puncture of brain substance.Cisternal puncture is not an appropriate alternative to a difficult lumbar puncture, and indications for its use are limited. The occasional required cisternal tap should be performed only by persons carefully trained in the technique, preferably utilizing fluoroscopic guidance, and only where neurosurgical assistance is readily available.Post-puncture subarachnoid hemorrhage accompanied by progressive obtundation requires emergency evaluation and consideration of posterior fossa decompression.
Insights
Cisternal puncture can cause severe neurologic damage, including fatal subarachnoid hemorrhage. This procedure is not a substitute for lumbar puncture and requires expert technique and neurosurgical support.
Area of Science:
- Neurology
- Neurosurgery
Background:
- Cisternal puncture is a neurosurgical procedure with potential for serious complications.
- Subarachnoid hemorrhage is a known risk, with at least 30 reported fatalities.
Purpose of the Study:
- To highlight the severe neurologic risks associated with cisternal puncture.
- To emphasize the limited indications and necessary precautions for cisternal puncture.
Main Methods:
- Case review of two patients experiencing acute neurologic damage after cisternal puncture.
- Analysis of reported fatalities and complications associated with the procedure.
Main Results:
- One patient died from subarachnoid hemorrhage post-cisternal puncture.
- The second patient recovered from brain stem infarction following cisterna magna injection.
- Subarachnoid hemorrhage is the most frequent severe complication.
Conclusions:
- Cisternal puncture carries significant risks and is not a suitable alternative for difficult lumbar punctures.
- The procedure should only be performed by highly trained personnel, ideally with fluoroscopic guidance and immediate neurosurgical availability.
- Emergency evaluation and potential posterior fossa decompression are critical for managing post-puncture subarachnoid hemorrhage with obtundation.
