 Since we are already on this, a region of the dissection, on this cadaver, I thought it would be appropriate to mention the finding that we can see here. We can obviously see that some sort of a surgery has been done here. It is my assessment that this patient sustained communicated multiple fractures of the skull bone here. And they have put a plate here, we can see that, with multiple small screws holding the fragment in place. Then they put another pin here, with multiple screws attaching these two fragments. Then they have put some sutures and we can see one suture here, we can see another suture here and we can see a few other sutures here. So they have tied these fragments. And finally, we can also see that in this area, there is bone loss, there is loss of outer table. And what we are seeing here is the diplo. So as I said, it is my assessment that this was a communicated fracture of the skull. And we can also see that in this region, the temporalis muscle is missing. Because this fracture had gone through the temporal line, the inferior and the superior temporal line. And correspondingly in this region, the temporalis fascia is also missing. Furthermore, it is also our assessment that in the time of the fracture or thereafter, there may have been intracerebral hemorrhage and even maybe subacnoid hemorrhage. And in order to opiate the possibility of secondary hydrocephalus developing, they inserted what we can see very clearly here, a ventricular peritoneal shunt. And we can see this is the ventricular end of the shunt going into the brain, into the ventricle. It usually goes to the lateral ventricle. We can see this portion of the shunt here. This is the reservoir, which enables the neurosurgeon to determine the patency of the shunt. It can be palpated from outside the scalp. Then below, we can see this is the region of the valve of the shunt, which ensures that fluid flows only downwards and not upwards. And then we can see this portion of the shunt here, which is the peritoneal end of the shunt, which has been tunneled under the skin of the neck. And it has gone all the way. It was tunneled under the skin of the chest, which we can see here. And it had gone through the rectus abdominis muscle and it had gone into the pelvic cavity. So this is the ventricular peritoneal shunt, which we feel they would have inserted to overcome a possible hydrocephalus, maybe because of subarachnoid hemorrhage. The ventricular end of the shunt and the peritoneal end of the shunt, both of these are radio opaque. So therefore, postoperatively, we can take an x-ray to confirm that these two ends of the shunt are intact and in position or not. So this is what we can see in this particular cadaver regarding the surgery. And what we said is our hypothesis that the postoperative injury and the shunt was in place to overcome hydrocephalus.
