Gelatin sponges, such as Gelfoam, are used as hemostatic agents during surgery and are generally absorbed over the course of 4-6 weeks in most body cavities. The time course of the dissolution of Gelfoam sponges within the cerebral ventricles has not been described.
The authors present a case of intraventricular migration of Gelfoam after ventriculoperitoneal shunt placement in a 6-week-old infant. The infant was imaged regularly after ventriculoperitoneal shunt placement, and the Gelfoam sponge persisted within the ventricles on all images until 11 months after surgery. At no time during follow-up did the patient have any symptoms of hydrocephalus requiring retrieval of the sponge or shunt revision.
This is the first case describing time until absorption of a gelatin sponge within the ventricle and successful conservative management.
明胶海绵，如明胶泡沫，在手术中用作止血剂，在大多数体腔内通常在4 - 6周内被吸收。明胶海绵在脑室内溶解的时间过程尚未见报道。
作者报告了一例6周龄婴儿在脑室腹腔分流术后明胶泡沫在脑室内迁移的病例。该婴儿在脑室腹腔分流术后定期进行影像学检查，明胶海绵在所有图像上均持续存在于脑室内，直至术后11个月。在随访期间，患者从未出现任何需要取出海绵或进行分流术修复的脑积水症状。
这是首例描述明胶海绵在脑室内吸收时间及成功保守治疗的病例。
