New Technique Seeking Prophylaxis in the Displacement of Distal Ventriculoperitoneal Shunt Catheter – Case Report

Abstract

AbstractIdiopathic intracranial hypertension is a comorbidity treated in neurosurgical practice today with the ventriculoperitoneal derivation technique. However, despite its great safety and efficacy, this technique is susceptible to infrequent failures, such as displacement of the catheter leading to the need for reoperation. In the present article, we report a case involving a peritoneal catheter tip retropulsion for subcutaneous tissue in an obese patient with posterior correction using an extending connector to the distal catheter, without harming the drainage flow. In our case report, the patient went on without complications and without the occurrence of new displacement after 8 months of surgery. The results obtained by this technique supported the idea that this alternative construction minimizes the risk of displacement of the peritoneal tip catheter in obese patients and with high intra-abdominal pressure, helping to reduce the need for reoperations. In addition, the present case report supports the need for further studies and clinical trials on the subject.
