Evaluation of ventriculoperitoneal shunt malfunction regarding ventricular catheter placement

AbstractBackgroundline of treatment for management of hydrocephalus despite available new techniques andsystems of shunting. Associated complications should be recognized and managed properly,but the most recognized complications are shunt obstruction which its prevalencethrough surgical approach is discussed here. Two approaches (frontal and parietal) are usedto insert ventriculoperitoneal shunt. In this study we retrospectively examined patterns ofshunt failure in patients with symptoms of shunt malfunction. Factors analyzed includedsite of failure, time from shunt placement or last revision of failure, age of patient at time offailure, infection and primary etiology of hydrocephalus. Two approaches were comparedto determine which one is more associated with shunt failure.: Shunting procedures specifically ventriculoperitoneal shunts are the mainMethodsretrospectively examined, in 126 cases who were shunted through frontal approach, 48 casesand in 124 patients whose shunts were inserted through parietal approach 64 cases ofmalfunction observed. All data was analyzed with SPSS software and with T-test,and thenthe failure rate for frontal versus parietal approach was compared.: 250 patients with symptoms of shunt malfunction over 4 years period wereResultsof underlying cause of ventriculoperitoneal shunt failure was observed, with theless failure rates through frontal approach.: Significant difference in malfunction rate between these two approaches regardlessConclusionshunt failure and frontal approach demonstrated less failure rate, but as it isknown placing the catheter tip away from the choroids plexus is the most important factoravoiding obstruction.: Although proximal obstruction is the most common cause of ventriculoperitoneal
