31 patients underwent ventricular shunting (17 VA and 14 VP) for post-haemorrhagic hydrocephalus over 11 years. The mean gestational age was 31.8 +/- 4.17 (1 SD) weeks and birth weight 1.83 +/- 0.77 (1 SD) kg, with no differences between the VA and VP groups. Shunts inserted less than 5 weeks of age failed more frequently than those inserted after 5 weeks. There were 5 early (less than 30 days) blocks all in VP shunts (p = 0.023) but no difference in distal catheter blockage rate (p = 0.14). There were no early infections. In later follow-up, 35% of patients had block episodes and 22% infective episodes with no significant difference between the type of shunt used. Overall mortality was 6.5% and not related to shunt complications. Revisions were more frequent in VP shunts (0.9 revisions/shunt year) than VA shunts (0.6 revs/shunt year). Using life table analysis 60% of VP and 30% of VA shunts failed within 2 years of insertion.
在11年期间，31例患者因出血后脑积水接受了脑室分流术（17例为脑室-心房分流术，14例为脑室-腹腔分流术）。平均胎龄为31.8±4.17（1标准差）周，出生体重为1.83±0.77（1标准差）kg，脑室-心房分流术组和脑室-腹腔分流术组之间无差异。出生后5周内插入的分流管比5周后插入的分流管失败频率更高。有5例早期（少于30天）堵塞，均发生在脑室-腹腔分流管（p = 0.023），但远端导管堵塞率无差异（p = 0.14）。无早期感染。在后期随访中，35%的患者出现堵塞事件，22%的患者出现感染事件，所用分流管类型之间无显著差异。总体死亡率为6.5%，与分流并发症无关。脑室-腹腔分流术的翻修频率（0.9次翻修/分流管年）高于脑室-心房分流术（0.6次翻修/分流管年）。使用生命表分析，60%的脑室-腹腔分流管和30%的脑室-心房分流管在插入后2年内失败。
