[Efficacy of early consecutive lumbar puncture treatment in aneurysmal subarachnoid hemorrhage after embolization].

Objective: To summarize the significance of lumbar punctures in remedy for aneurysmal subarachnoid hemorrhage (aSAH) after embolization.

Methods: From December 2002 to September 2011, 43 cases of aSAH underwent aneurysm embolization at department of interventional radiology and vascular surgery, Peking University Third Hospital. After the embolization,consecutive lumbar punctures were undertaken everyday, by which we measured proper cerebrospinal fluid pressure and slow drainage of cerebrospinal fluid. In accordance with the lumbar puncture results we determined the control of blood pressure, dehydration and rehydration therapy procedures.

Results: Two patients died. Only one patient in the 41 cases of the survived patients developed cerebral vasospasm, cerebral infarction and obstructive hydrocephalus, but by ventriculo-peritoneal shunt, obstructive hydrocephalus was relieved. The remaining 39 patients recovered well. After the mean follow-up of (26.0±5.8) months, no new neurological symptoms were found.

Conclusion: Early consecutive lumbar puncture treatment in ASH after embolization is significant.
