Long-term surgical outcomes of XXXX .

@entity1 @entity1283 @entity602 @entity5254
BACKGROUND: Because of the lack of long-term postoperative follow-up studies of @entity602 ( @entity602 ), there is little information about the long-term effectiveness and complications of the dural defect enlargement in @entity1 with @entity602 . The purpose of this study is to determine the long-term effectiveness of this procedure. METHODS: Sixteen @entity1 with @entity602 were treated surgically by @entity1283 . The @entity1 's neurological status and surgical outcome were evaluated by the JOA scores for thoracic @entity602 and the recovery rate (mean follow-up period 9.6  years). Correlations between the surgical outcomes and @entity1 ' age and duration of disease were assessed retrospectively. The @entity1 were also divided into two groups based on the location of the dural defect: the ventro-lateral (VL) group and the ventral (V) group. The difference in the duration of disease, preoperative JOA score, and the recovery rate were compared between the two groups. RESULTS: There was no recurrence of @entity602 after surgery. The mean recovery rate was 42.6%. There was a significant correlation between the @entity1 's age and the recovery rate, and between the duration of disease and the recovery rate. The median recovery rate was significantly lower in the V group than in the VL group. There were no complications related to @entity5254 after surgery. CONCLUSIONS: Long-term surgical outcomes of @entity1283 for @entity602 were stable and favorable without recurrences or any complications. This procedure should be considered for @entity1 with @entity602 before their neurological deficit worsens, especially for the @entity1 in whom the dural defect is located at the ventral part of the dural canal.
