Latex and silicon allergy related to cerebrospinal shunt hardware: a review

Abstract

A less frequent complications of shunt systems ventriculoperitoneal used for the management of hydrocephalus is the allergy materials which usually are built, silicone and latex. Patients undergoing multiple changes device may be at risk of developing high rejection to materials. Differential diagnosis should be done with infections and obstructions, usual causes of dysfunction. We present a review updated literature focused neurosurgeon.

Subcutaneous granulomatous reaction with eosinophil infiltration to a silicone continuous ambulatory peritoneal dialysis Tenckhoff catheter

“…Medical silicone resin is widely used in clinical applications . Two types of medical silicone resin are in use: vinyl specific and non‐vinyl specific.…”

“…Although numerous silicone granulomas after breast implants had been documented, reports of skin granuloma by indwelling catheters are rare . A few hypotheses concerning the pathogenesis of silicone granuloma are proposed, such as a foreign body‐type reaction and immunogenic effect of silicone .…”

“…Medical silicone resin is widely used in clinical applications. 3,4 Two types of medical silicone resin are in use: vinyl specific and non-vinyl specific. Chemical modifications applied to vinyl-specific silicone resin add flexibility at low temperatures, high-temperature stability, and radiation stability.…”

“…Although numerous silicone granulomas after breast implants had been documented, 6 reports of skin granuloma by indwelling catheters are rare. 4,7 A few hypotheses concerning the pathogenesis of silicone granuloma are proposed, such as a foreign body-type reaction 8 and immunogenic effect of silicone. 9 A unique point of our case was that eosinophil infiltration was histologically observed in granulomas around the CAPD catheter as well as in the skin reaction to the scratch-patch test.…”

Aspergillus growth within ventriculoperitoneal shunt tube

“…[ 1 ] Allergy or hypersensitivity to latex or silicone is now emerging. [ 2 ] Extrusion of the peritoneal end of the shunt through intact skin over the abdominal end is extremely rare. Aspergillosis is a serious infection caused by the proliferation and invasion of hyphae in tissue.…”
