儿童四叠体池蛛网膜囊肿临床特点及疗效分析：一项定量回顾性研究
Clinical characteristics and surgical outcome analysis of quadrigeminal cistern arachnoid cysts in children: a quantitative retrospective cohort study
Note： A. Correlation analysis of various indicators. Moderate correlations (0.5≤|rₛ|<0.7) were observed between cyst volume and cyst count (rₛ=0.54), as well as between cyst volume and cyst location (rₛ=0.62). Weak correlations (0.3≤|rₛ|<0.5) were identified between clinical symptoms and patient age (rₛ=0.43), cyst location and age (rₛ=-0.48), Evans index and cyst count (rₛ=0.41), and Evans index and cyst volume (rₛ=0.45). B. Postoperative changes in cyst volume at the 3-month follow-up. Among in the 27 pediatric cases, the absolute value of change rate in cyst volume ranged from 0.004 to 1.810, with a median change rate of 0.360. C/D. Overall change rates of cyst volume and Evans index during follow-up. Panels C and D depict the overall change rates of cyst volume and Evans index at the 3-, 12-, and 24-month postoperative follow-ups. The change rate of cyst volume was greatest at 3 months and subsequently declined. In contrast, the change rate of the Evans index was most pronounced at 24 months. E/F. Longitudinal changes in cyst volume and Evans index in 8 cases after initial surgery. Panels E and F illustrate the longitudinal changes in cyst volume and Evans index preoperatively and at 3, 12, and 24 months postoperatively in 8 patients who underwent initial surgery. The trends for both metrics were concordant across all 8 cases. A marked reduction was observed in 2 cases (ID 6, 12), relative stability in 4 cases (ID 14, 15, 18, 21), and a notable increase in 2 cases (ID 8, 10). T1—preoperatively; T2, T3, and T4—3, 12, and 24 months postoperatively, respectively.
