Background. Ventriculoperitoneal (VP) shunt is the most common neurosurgical procedure to treat obstructive and communicating hydrocephalus in children and adults but failure are frequent. The knowledge of risk factors related to abdominal shunt failure is useful to avoid complications.
Patients and methods. We analyze retrospectively 86 adults patients affected by obstructive and communicating hydrocephalus operated for VP shunt at our Institution. Statistical analysis was performed in order to correlate shunt malfunctioning with type of abdominal approach (trocar vs mini-laparotomy), perioperative infective status, sex, bowel distention and length of surgical time.
Results. Factors statistically significant for surgical shunt revision were the use of trocar (univariate analisys p=0,029 and multivariate p= 0,035) and high infective risk (univariate analisys p=0,028 and multivariate p= 0,038). No statistical significant association was observed between shunt revision and sex, bowel distension and operative length time.
Conclusions. To avoid postoperative shunt malfunctions especially in peritoneum the mini-laparotomy is the approach of choice. Surgery must be performed when infective status is healed.
