Cerebral Palsy maybe/maybe not

surface and thus seldom show typical hemiplegia patterns (at least those caused by single artery blockage). In anticipation of the shearing caused by the floating skull plates in the birth process, these extra vessels on the outer surface are removed late in pregnancy. Bleeding But hemiplegia may also result from a right sided or a left sided intracranial hemorrhage (bleeding). In this case, damage is less road-like (following the artery) and more lake-like (under the pool of bleeding). Occasionally the bleeding, by sheer volume, can displace the brain and cause secondary injuries well away from the prime bleeding area. These secondary injuries caused by herniation from pressure or shifting also need to be addressed as additional injuries on top of the hemiplegia. There are only three main arteries. The middle one is the most at risk, hence the typical pattern of damage.

In all of the cp types, bleeding can do the obvious, but that blood clots. Those clots can plug up the CSF (cerebrospinal fluid) passages at narrow flow areas. This is why CSF shunts are placed to let that fluid get to an alternative disposal area (in the belly – peritoneal cavity). Shunt from ventricles to peritoneum = VP shunt.
