What are the possible complications during the procedure? Pacemaker installation is a minimally invasive procedure, and the most likely complication during the procedure is a trauma to a blood vessel that could lead to a cerebral hemorrhage, which could cause a serious adverse reaction. This is the most likely complication that can cause serious adverse effects during surgery. If the distribution of blood vessels is clarified through preoperative examination, intraoperative damage to blood vessels can be minimized. What are the risks to the patient if a blood vessel is accidentally touched? Once a cerebral blood vessel is injured causing a brain hemorrhage, the blood will take over the tissue structure of the brain, which will affect the normal work of the central nervous system and may lead to problems such as speech impairment and hemiplegia. However, it is relatively rare for these complications to occur with pacemaker surgery. Is it possible to have a tiny wound that is difficult to heal with a pacemaker? This can happen, especially in elderly male patients. The traditional pacemaker implantation procedure is usually a straight incision, where a hole is drilled in the skull under the skin to implant the stimulation electrode and place the fixation device. However, in elderly male patients, there is very little subcutaneous fat, and the older they get, the thinner their scalp becomes, and the more likely it is that the area with the foreign body will become infected or not heal. In view of the problem that the wound does not heal easily, the neurosurgery department specially made a curved incision for the patient to bypass the foreign body underneath. After the wound is closed, there will not be any foreign body underneath the incision to minimize the problem of poor wound healing. What factors can affect the outcome of the surgery? The factors that affect the effect of the surgery include the following: 1. Clear diagnosis is required: At present, it is mainly patients diagnosed with Parkinson’s disease or dystonia that the installation of a brain pacemaker will be effective. Parkinson’s disease needs to be distinguished from Parkinson’s syndrome because Parkinson’s syndrome is not suitable for the installation of a brain pacemaker, only Parkinson’s disease is, and this requires the cooperation of neurology for identification. If the neurology department confirms the diagnosis of Parkinson’s disease, then the post-operative effect will be obvious. 2, the surgical target should be accurate: only the surgical target is accurate to ensure good efficacy. 3, post-operative regulation: surgery is only to put the pacemaker in, post-operative regulation is a process to really make it work. Therefore, after surgery, the brain pacemaker should be adjusted to a suitable state and combined with drug therapy to really make the brain pacemaker work. Therefore, preoperative diagnosis, intraoperative target accuracy, and postoperative regulation and medication adjustment are all decisive factors affecting the efficacy of the pacemaker. In view of this, the hospital has established a comprehensive treatment team, including neurological surgery, neuropsychology, neurorehabilitation, and a post-operative regulation center.
