Reply to the Editor:
We appreciate the comments regarding our article by Oberwalder and colleagues and thank them for the valuable adjuncts regarding cerebrospinal fluid (CSF) drainage in stent-graft implantation.
Because of the restricted number of references in brief communications, we considered only publications in the high-impact journals. Nevertheless, we are aware of the report of Tiesenhausen and associates,
1 who described for the first time the impact of CSF drainage in a case of paraplegia after stent-graft implantation.
To close the entry tear in the descending aorta it is sometimes necessary to deploy a stent graft in the region (Th 8- L2) most prone to ischemia, but we agree that this should be avoided whenever possible. However, the risk of paraplegia has to balanced against the risk of rupture of the aneurysm in these patients.
Routine use of CSF drainage in stent-graft implantations could help to reduce the risk of paraplegia in such cases.
