Characteristics of ventricular shunt malfunctions among patients with neurocysticercosis
Abstract
Ventricular shunts used to relieve hydrocephalus among patients with neurocysticercosis have been plagued by high shunt malfunction rates. We examined the characteristics of shunt malfunctions among patients with neurocysticercosis. This is a retrospective chart review of data for 122 patients who were admitted with a diagnosis of cysticercosis during a 5.5-year period. Cases of hydrocephalus requiring shunt placement were reviewed with respect to the segment of shunt obstruction, disease activity at the time of shunt placement, and the effects of antihelminthic treatment on shunt failures and longevity. Twenty-one patients required 49 operations for relief of hydrocephalus, including 22 new shunt placements, 23 revisions, and 4 cyst extirpations. Of these shunt failures, 78% occurred within the first 12 months and 96% within 3 years. Of the failures that occurred in the distal segment, 75% occurred within 6 months. By comparison, 33% of proximal segment obstructions and 50% of the total number of valve obstructions occurred within the first 6 months. Of the shunts placed during the vesicular stage of infection, 63% required revisions, compared with 29% of those placed during the colloidal through calcified stages. Nineteen shu...Continue Reading

Anthelmintics (ASM)
Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
