Shunt infection

What it is

Shunt infection is an infection involving the shunt system. It is a serious complication that usually requires treating the infection with antibiotics and, in most cases, removing the infected shunt hardware.

Understanding Shunt infection

Most shunt infections occur in the period soon after the shunt is placed or revised (often within the first few months), typically from bacteria introduced at the time of surgery. Reported infection rates vary but are often in the range of a few to around fifteen percent in children. Signs can include fever, redness or swelling along the shunt tract, irritability, poor feeding, or signs of malfunction, and sometimes signs of meningitis. Treatment generally involves antibiotics and, in most cases, removing the infected hardware — often with temporary external drainage in the meantime — followed by placing a new shunt once the infection clears. Because shunt infection is serious, recognizing the signs (especially fever with shunt symptoms) and seeking prompt care is important. Infection-prevention measures aim to reduce its occurrence.

Why it matters

Understanding shunt infection helps families recognize a serious complication, know its warning signs (such as fever with shunt symptoms), and understand why prompt care and, usually, removing the infected hardware are part of treatment.
