The validity of clinical studies on shunt-treated hydrocephalic patients is often hindered by inhomogeneity of the patient population examined, technical devices used, or by other specific factors. In an effort to introduce a homogeneous clinical study on hydrocephalic patients 66 hydrocephalic newborns and infants have been treated exclusively with CORDIS Orbis-Sigma Valve (OSV) System (CORDIS Corporation, Miami, USA) in 1990-1995. The results are compared with an equivalent group of 53 children treated with CODMAN Holter Valve (HV) System (CODMAN Inc., Randolph, USA) during a similar 5-year-period (e.g., 1986-1991). Searching for different reasons of shunt insufficiency in both groups demonstrates a more than double risk of shunt complication for ventriculo-atrial HV treated patients (VA-HV) in comparison with those treated ventriculo-peritoneally with OSV System (VP-OSV): 4.22 versus 1.98 mean surgical procedures per person. The different revision and survival rates are discussed and specific problems are mentioned.

“…Complications following insertion of VP shunts for the treatment of hydrocephalus are numerous and have been well documented [4,[8][9][10][11][12][13][14], In analyzing the contributing factors in shunt complications, Griebel et al [81 found the surgeon performing the procedure and the type of shunt used to be highly significant correlates.…”

Disconnection as a Cause of Ventriculoperitoneal Shunt Malfunction in Multicomponent Shunt Systems

The cause of malfunction in 275 consecutive ventriculoperitoneal (VP) shunt revisions over an 8-year period were retrospectively analyzed. In all cases the shunt revised was a multicomponent (Holter) VP shunt. Disconnections in the system accounted for 41 (15%) of the malfunctions. The more distal the connection was from the ventricle, the higher the likelihood of disconnection. Furthermore, occipitally placed shunts had a significantly higher tendency to dislocate than frontally placed shunts.

“…Excluding the unishunt system, all shunts included connectors [ 14,26], However, the connection site is often the surgeon's choice. For instance, the majority of the de tached ventricular catheters lost in the ventricles are those which were ligatured under the skull (burr hole reservoir).…”

A retrospective study was conducted on 1,719 hydrocephalic patients, treated between 1974 and 1983 at the Hospital for Sick Children (Toronto) and l’Hôpital des Enfants Malades (Paris), in order to better understand shunt failure. The statistical analysis demonstrates the following: (1) A probability of occurrence of shunt malfunction of 81 % at 12 years of follow-up. (2) A high prevalence of shunt obstruction (56.1% of all malfunction) and fracture or disconnection of the tubings (13.6%). (3) A higher risk of proximal occlusion with flanged ventricular catheter. (4) Less malfunction with proximal-non-slit valves as compared to distal-slit valves. (5) The importance of pressure-flow characteristics of the shunt; because of an indircet relation between overdrainage and proximal occlusion. (6) A correlation between connectors and migration or fracture of the shunt. (7) Less distal obstructions when an open-ended distal-catheter was used. These complications were of some clinical, psychological and economical consequences. Their rate could be lowed.
