Case Responses
Delay in diagnosis of anterior communicating aneurysm with intracerebral hemorrhage. (Case #442)

- Causation Probability: 5 / 10
- Causation Summary: The neurological sequela seems to be related to initial subarachnoid and intraparenchymal hemorrhage insult.

- Similar Summary: Every week and sometimes multiple times a week
**PEDIATRIC NS EXPERT REQUESTED** Malpositioned ventricular stent leading to neuro deficit. (Case #461)
- Medical Probability: 5 / 10

- Causation Probability: 6 / 10
- Causation Summary: Lack of thorough assessment of shunt dysfunction, and lack of urgent attention for consideration of a possible revision.
- Expert Summary: This is a general neurosurgery case. Any neurosurgeon should know how and when to deal with a dysfunctional shunt in a patient who is shunt dependent. It is basic.
- Similar Summary: I am a sub-specialized neurosurgeon but will still see about 5-10 patients with suspicion of shunt dysfunction in the ER every year and some necessitate urgent revision.
