line of treatment for management of hydrocephalus despite available new techniques and

systems of shunting. Associated complications should be recognized and managed properly,

but the most recognized complications are shunt obstruction which its prevalence

through surgical approach is discussed here. Two approaches (frontal and parietal) are used

to insert ventriculoperitoneal shunt. In this study we retrospectively examined patterns of

shunt failure in patients with symptoms of shunt malfunction. Factors analyzed included

site of failure, time from shunt placement or last revision of failure, age of patient at time of

failure, infection and primary etiology of hydrocephalus. Two approaches were compared

to determine which one is more associated with shunt failure.

: Shunting procedures specifically ventriculoperitoneal shunts are the main


retrospectively examined, in 126 cases who were shunted through frontal approach, 48 cases

and in 124 patients whose shunts were inserted through parietal approach 64 cases of

malfunction observed. All data was analyzed with SPSS software and with T-test,and then

the failure rate for frontal versus parietal approach was compared.

: 250 patients with symptoms of shunt malfunction over 4 years period were


of underlying cause of ventriculoperitoneal shunt failure was observed, with the

less failure rates through frontal approach.

: Significant difference in malfunction rate between these two approaches regardless


shunt failure and frontal approach demonstrated less failure rate, but as it is

known placing the catheter tip away from the choroids plexus is the most important factor

avoiding obstruction.

: Although proximal obstruction is the most common cause of ventriculoperitoneal
