Patients who are affected by Parkinson\u2019s disease may benefit from DBS of either the subthalamic nucleus or the globus pallidus internus. Patients who undergo DBS often notice a significant reduction in their clinical symptoms; however, the procedure is not without risks. Multicenter studies have reported postoperative complications such as hardware infection, intracranial hemorrhage, and perielectrode edema.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>The authors report a case of a perielectrode cyst managed conservatively. Tracking the impedance trend was a novel approach to monitor for changes within the cyst and to herald a clinical change in the patient. Perielectrode cystic formation can be a transient process that resolves spontaneously or with conservative, nonoperative management, and all diagnostic information is valuable in making clinical decisions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>Impedance values have provided an appropriate estimation of this patient\u2019s clinical picture. The authors suggest treatment of edema and a cyst after DBS lead implantation through conservative management and observation, avoiding the removal of hardware if a patient\u2019s clinical picture is either stable or improving and forgoing additional clinical imaging if the impedance values are trending in an appropriate direction.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case23349","type":"journal-article","created":{"date-parts":[[2023,9,18]],"date-time":"2023-09-18T21:15:29Z","timestamp":1695071729000},"source":"Crossref","is-referenced-by-count":3,"title":["Impedance trend from a symptomatic perielectrode cystic cavity following deep brain stimulation: illustrative case"],"prefix":"10.3171","volume":"6","author":[{"given":"Brooke","family":"Elberson","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hayden","family":"Scott","sequence":"additional","affiliation":[{"name":"Surgery, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rohit","family":"Dhall","sequence":"additional","affiliation":[{"name":"Neurology, University of Arkansas for Medical Sciences, Little Rock, Arkansas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erika","family":"Petersen","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"1","key":"b1","series-title":"J Neurosurg","first-page":"132","article-title":"Risks of common complications in deep brain stimulation surgery: management and avoidance","volume":"120","author":"Fenoy AJ","year":"2014","unstructured":"Fenoy AJ, Simpson RK Jr. Risks of common complications in deep brain stimulation surgery: management and avoidance.
