This article aims to describe an extraordinary complication of a ventriculoperitoneal shunt system that formed a knot spontaneously and lead to a shunt malfunction. A 3-year-old male patient was operated due to posttraumatic hydrocephalus. After an uneventful follow-up period of 34 months, he presented with shunt malfunction. During the shunt revision surgery, the peritoneal catheter was found to form a loop over itself. There are various complications of ventriculoperitoneal shunt systems. Migration to body cavities is among the most interesting ones. This is the fifth report describing this rare complication. Hydrocephalic patients should be closely followed up after shunt surgery for various extraordinary complications. KeywOrds: V/P Shunt, Shunt Complication, Shunt Malfunction ÖZBu makale, kendi üzerine katlanarak bir düğüm oluşturup şant malfonksiyonuna neden olan ventriküloperitoneal şant sisteminin yol açtığı bu sıradışı bir komplikasyonu incelemektedir. Travma sonrasında gelişen hidrosefali nedeni ile opere edilen 3 yaşındaki erkek hasta 34 aylık sorunsuz bir takip süresi ardından şant malfonksiyonu ile başvurdu. Şant revizyonu sırasında peritoneal kateterin kendi üzerine katlanarak bir düğüm oluşturduğu gözlendi. Ventriküloperitoneal şant sistemlerine ait birçok farklı komplikasyon bildirilmiştir. Vücut boşluklarına migrasyon bu komplikasyonlardan en ilginç olanlar arasındadır. Bu makalede, sunulan vaka literatürdeki beşinci vakadır. Hidrosefalili hastalar şant cerrahisi sonrasında bu komplikasyonlar için yakın takipte tutulmalıdırlar.

The course of AMRR during radiotherapy can differ between individual patients. After the initial increase in AMRR intensity, a stabilization of the reaction--visible as a plateau phase on the course curve--is observed in the majority of patients. A proportion of the irradiated patients experience a continual increase in AMRR intensity up until the end of radiotherapy. A further group of patients exists in whom signs of AMRR healing are observed during the final stages of radiotherapy.
