The surgery itself can cause complications. [3] Damage to a blood vessel may cause intracranial haemorrhage. [3] Damage to the optic tract can cause a permanent vision problem. [3] Pressure on brain tissue can induce a seizure. [3]
Frequently a groove or indentation is seen in the nerve where the offending vessel was in contact with the nerve. Less often the nerve is thin and pale. Once the vessel is mobilized a sponge like material is placed between the nerve and the offending blood vessel to prevent the vessel from returning to its native position.
Leptomeningeal collateral vessels from the anterior cerebral artery and posterior cerebral artery appeared to allow for perfusion of some brain tissue to persist, partially compensating for the loss of the major vessel. [6] This compensatory effect is however usually inadequate to maintain a normal blood supply. [11]
It is thought that it may be caused by the body's inflammatory response to surgery, stress hormone release during surgery, ischemia, or hypoxaemia. [5] [6] Post-operative cognitive dysfunction can complicate a person's recovery from surgery, delay discharge from hospital, delay returning to work following surgery, and reduce a person's quality ...
Endovascular coiling is an endovascular treatment for intracranial aneurysms and bleeding throughout the body. The procedure reduces blood circulation to an aneurysm or blood vessel through the implantation of detachable platinum wires, with the clinician inserting one or more into the blood vessel or aneurysm until it is determined that blood flow is no longer occurring within the space.
If MSC treatment becomes available for stroke patients, it is possible that current mortality and morbidity rates could substantially improve due to the direct enhancement of neuroprotection and neurorestoration mechanisms rather than only indirect facilitation or prevention of further damage, e.g. decompressive surgery. However, for MSC ...
A subdural hematoma (SDH) is a type of bleeding in which a collection of blood—usually but not always associated with a traumatic brain injury—gathers between the inner layer of the dura mater and the arachnoid mater of the meninges surrounding the brain. It usually results from rips in bridging veins that cross the subdural space.
Hemispherectomy is a surgery that is performed by a neurosurgeon where an unhealthy hemisphere of the brain is disconnected or removed. There are two types of hemispherectomy. Functional hemispherectomy refers to when the diseased brain is simply disconnected so that it can no longer send signals to the rest of the brain and body.
