New Technique Seeking Prophylaxis in the Displacement of Distal Ventriculoperitoneal Shunt Catheter – Case Report
Nova técnica buscando profilaxia no desacoplamento do cateter distal de derivação ventriculoperitoneal – Relato de caso Funding The present work and its authors did not receive any form of external funding.
Abstract
Idiopathic 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.
Resumo
A hipertensão intracraniana idiopática é uma comorbidade tratada na prática neurocirúrgica usualmente com técnica de derivação ventriculoperitoneal. No entanto, apesar de sua grande segurança e eficácia, a técnica é sujeita a falhas, pouco frequentes, como o desacoplamento do cateter, levando à necessidade de reoperação. Relatamos, no presente artigo, um caso de correção cirúrgica a partir de prolongamento do cateter distal com a utilização de conector extensor sem prejuízo ao fluxo de drenagem em paciente obeso acometido por recidiva de migração da ponta do cateter peritoneal para o tecido subcutâneo. Em nosso relato de caso, o paciente seguiu sem complicações e sem a ocorrência de novos desacoplamentos após 8 meses do ato operatório. Os resultados obtidos pelo estudo corroboram a necessidade de maiores investigações buscando o conhecimento da eficácia e segurança da técnica empregada buscando minimizar os riscos de migração da ponta do cateter peritoneal em pacientes obesos e de elevada pressão intra-abdominal, ajudando a diminuir a necessidade de reoperações.
