Due to increased number of patients suffering from hydrocephalus (HCP) and lack of data concerning volumetric changes after shunting operations, this study aims to assess the volumetric changes in brain ventricles after successful ventriculoperitoneal (VP) shunt surgery in correlation with clinical improvement. This study included 20 patients; all of them are below the age of 2 years. All the patients had hydrocephalus, were treated surgically with VP shunts, and have clinically improved over the period of study. We measured the volumetric changes radiologically using the fronto-occipital horn ratio (FOHR) over a period of 6 months postoperatively. The frontal and occipital horn ratio was calculated in all these patients both pre and postoperatively. There was a significant radiological improvement in the majority of children after the shunt operation. One month postoperatively, the FOHR decreased to about 85% of its preoperative value in average. The FOHR was found to be significantly improving with time over a period of 6 months reaching 63% of its preoperative value. Successful treatment of HCP in infants via VPS seems to be of benefit in decreasing the ventricular size gradually to a near normal FOHR with clinical improvement.

脑积水婴儿成功分流后的心室容积变化

由于患有脑积水（HCP）的患者人数增加，并且缺乏有关分流手术后容量变化的数据，因此本研究旨在评估成功的心室腹膜（VP）分流手术后脑室的容量变化以及临床改善。这项研究包括20例患者。他们都不到2岁。所有患者均患有脑积水，接受了VP分流术的手术治疗，并且在研究期间临床上有所改善。我们在术后6个月内使用额枕角比率（FOHR）放射学测量了体积变化。计算所有这些患者术前和术后的额角和枕角比例。分流手术后，大多数儿童的放射学有了明显改善。术后一个月，FOHR平均降低至术前值的约85％。发现FOHR在6个月的时间内显着改善，达到术前价值的63％。通过VPS成功治疗婴儿的HCP似乎有益于随着临床的改善逐渐将心室大小减小至接近正常的FOHR。
