Event Description
It was reported that before the shunt, the patient had an operation to remove a brain tumor (pilocytic astrocytoma), and an external lateral ventricular drain (evd) was placed on the right on (b)(6) 2020.On (b)(6) 2020, the drainage system was removed due to ventricular bleeding.Over the next 24 days, cerebrospinal fluid (csf) was repaired.There were no signs of infection in the csf during the whole period, and the patient received antibiotic-prophylactic.On (b)(6) 2020 the patient was implanted with a ventriculoperitoneal shunt without any complication.The valve performance was set at 2.The next day, the healthcare professionals (hcp) noticed signs of shunt insufficiency.The patient was experiencing drowsiness, and rising sun sign.Ct of the head showed a typical placement of ventricular catheter in the lateral ventricle with no signs of bleeding.The valve performance was reduced to 1 and then to 0.5, but due to the lack of positive development, on (b)(6) 2020, a shunt revision was performed where a blockage with blood particles of the ventricular catheter was observed.It was stated that this was cleared up.After the operation, the hcp observed no positive development so a double shunt revision was fulfilled.As a result of the revision, it was found that the peritoneal and ventricular catheters were open.At that time, it was assumed that the shunt peritoneal catheter made a hook in the tunnel in which was corrected by stretching during the placement back of the catheter.Several hours later after the operation, signs of tentorium occlusion developed mostly on the left side (coma, expressed rising sun sign, 6th nerve function insufficiency).The valve performance was checked which was the same at 0.5.Urgently, on (b)(6) 2020, an evd was placed on the left side.The shunt system has not been removed.Treatment has continued in the icu.The patient's condition has been assessed as severe during the last 2 weeks.Until (b)(6) 2021, the patient was on respiration with a low level of consciousness (coma, then sopor).The external drainage reservoir was located 10-12 cm above the external auditory canal; however, daily 400-450 ml accumulated in the reservoir.Positive dynamics was noticeable in the last 3 days.The patient opened their eyes, moved limbs, and followed some instructions.On (b)(6) 2021, an mri examination of the head was performed, and the results showed decreased ventriculomegaly, lack of continuous tumor growth but signs of hemorrhage on the left side of the midbrain as a result of the tentorium occlusion.Consultation with the neurosurgeons came to the conclusion that there was a problem with the valve.
 
Event Description
Additional information received reported that the peritoneal and the ventricular catheters were from another manufacturer that was compatible with the valve.It was stated that 2 shunt revisions were made, and during the second revision, they excluded blockage of the catheters as well as blockage of the valve.Since the valve settings were on the lowest setting (0.5), no actions were taken to change anything with the valve.A new evd was implanted into the patient in another ventricle to solve their hydrocephalus and save their life.It was noted that the by the impression of the doctors, the valve was functioning but not enough in correspondence to it's setting of 0.5.The shunt system was explanted on (b)(6) 2021.
