The role of different imaging modalities: is MRI a conditio sine qua non for ETV?

Abstract

The authors conclude that MRI is a conditio sine qua non for ETV in elective surgical cases.

Microsurgical third ventriculocisternostomy as an alternative to ETV: report of two cases

“…In the last two decades, endoscopic third ventriculocisternostomy (ETV) via a precoronal burr hole and transfrontal approach became a good therapeutic alternative to shunt placing and in non-communicating hydrocephalus, ETV has become the first choice of treatment [ 29 ]. Also, ETV is more and more offered to patients with shunt at the time of shunt malfunction or in case of slit-ventricle syndrome (SVS) as a means to become shunt independent.…”

Adjustable shunt valve–induced magnetic resonance imaging artifact: a comparative study

“…In addition, patients with an implanted shunt valve might need MR imaging with different pulse sequences (such as DW imaging or gradient echo sequences) to investigate a separate or associated brain condition. 4,15,20,21 Most of the adjustable shunt valves rely on intrinsic magnetic components, the position of which can be noninvasively altered using an external adjustment magnetic device. Inevitably, the shunt valve induces artifacts on MR images; this has been studied as part of the assessment of shunt valve MR imaging safety, mainly ex vivo.…”
