“…14 Similarly, other studies have shown failure rates of 18.7% to 64% within 3 years and as high as 50% within the first 12 months for shunts placed in patients with IIH, with most studies showing failure rates greater than 40% at 1 year. [17][18][19][20][23][24][25] This failure rate is likely due to the decreased ventricle size in patients with IIH, which makes catheter positioning difficult and increases the possibility for occlusion from the brain collapsing around the catheter.…”

“…In addition, LPS is prone to failure because of the extremely small catheter diameters, with 35% to 86% needing revisions within 2 years. [17][18][19][20] Consequently, patients with IIH are often left unsatisfied or require frequent shunt revisions.…”

“…Altta yatan bir nedene bağlı gelişme olasılığının daha yüksek olması, kronikleşme ve nüks oranlarının daha düşük olması ile göreceli daha iyi prognoza sahip olması nedeniyle erişkin çağı psödotümör serebrilerinden farklıdır (1-4). Psödotümör serebrili erişkin hastalarda sık etiyolojik nedenlerinden biri obezitedir (9,21). Ancak çocukluk çağında obezite daha nadir eşlik etmektedir (22).…”

“…However, even this rate of failure is significantly lower than rates described in studies of CSF shunting. Greener et al, 43 for example, found that by 3 years post shunt, only 52% of IIH patients still had a surviving shunt, and the median survival of the initial shunt was 23 months. Furthermore, causes of failure included infection, which can be associated with morbidity and mortality over and above the associated worsening of IIH, a complication that does not affect venous stents.…”
