Commercially available port systems may be unavailable or cost-prohibitive in certain practice environments.<\/jats:p>\n <\/jats:sec>\n \n Case Description:<\/jats:title>\n Case #1 involved a 69-year-old man who presented with mild cognitive changes and gait disturbance and was found to have a left parietal enhancing mass consistent with a high-grade glioma. Case #2 involved a 63-year-old man who presented 5 months following prior resection with right-sided focal motor seizures and a recurrent left frontal lobe, premotor cortex glioblastoma multiforme. Case #3 involved a 49-year-old right-handed man who presented to the emergency department with a Glasgow Coma Scale of 8. Head computed tomography demonstrated a 65 cc intracerebral hematoma with surrounding edema involving the right thalamus and basal ganglia, bilateral lateral ventricle intraventricular hemorrhage, and 5 mm right-to-left midline shift. Case #4 involved a 77-year-old man with a 3.5 cm left frontal mass consistent with metastatic tumor, significant associated vasogenic edema, left-to-right midline shift, and herniation. In the absence of a dedicated MIPS port system, a balloon-expandable covered vascular stent was repurposed as a temporary intracranial access port using image guidance. Tumor resections in Cases 1, 2, and 4 were performed through the repurposed balloon-expandable covered stent port. GammaTile post-resection brachytherapy placement was accomplished through the stent port in Cases 1 and 4. In Case #3, intentional hematoma debulking was performed using stent port access. Gross total resection\/complete resection was achieved in all three neoplasm cases. Post-operative imaging confirmed complete resections of both Grade IV glial neoplasms and complete resection of the Case #4 left frontal metastatic mass. In the hematoma case, intentional subtotal 30 cc evacuation was achieved.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Balloon-expandable covered stents may represent a feasible alternative access port for MIPS procedures in select clinical circumstances.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_433_2026","type":"journal-article","created":{"date-parts":[[2026,8,21]],"date-time":"2026-08-21T08:48:15Z","timestamp":1787302095000},"page":"481","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Minimally invasive port stent surgery: Re-purposing a balloon-expandable covered vascular stent for minimally invasive resection of deep cerebral masses: Report of 4 first-in-human stent port cases"],"prefix":"10.25259","volume":"17","author":[{"given":"Michael B.","family":"Horowitz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2026,8,21]]},"reference":[{"key":"10.25259\/SNI_433_2026\/ref-1","first-page":"282","article-title":"Stereotactically guided endoscopic port surgery for intraventricular tumor and colloid cyst resection","volume":"79","author":"Engh","year":"2016","journal-title":"Neurosurgery"},{"key":"10.25259\/SNI_433_2026\/ref-2","doi-asserted-by":"crossref","first-page":"3051","DOI":"10.1007\/s00381-024-06417-5","article-title":"Cylinder tumor surgery in pediatric low-grade gliomas","volume":"40","author":"Jaimovich","year":"2024","journal-title":"Childs Nerv Syst"},{"key":"10.25259\/SNI_433_2026\/ref-3","doi-asserted-by":"crossref","first-page":"S18.e1","DOI":"10.1016\/j.wneu.2012.02.022","article-title":"Endoneurosurgical resection of intraventricular and intraparenchymal lesions using the port technique","volume":"79","author":"McLaughlin","year":"2013","journal-title":"World Neurosurg"},{"key":"10.25259\/SNI_433_2026\/ref-4","doi-asserted-by":"crossref","first-page":"1611","DOI":"10.1007\/s10143-020-01349-5","article-title":"Minimally invasive trans-sulcal parafascicular surgical resection of cerebral tumors: Translating anatomy to early clinical experience","volume":"44","author":"Monroy-Sosa","year":"2021","journal-title":"Neurosurg Rev"},{"key":"10.25259\/SNI_433_2026\/ref-5","article-title":"Proceedings of the ASME 2021 Design of Medical Devices Conference","volume-title":"Minneapolis","author":"Yoo","year":"2021"}],"container-title":["Surgical Neurology International"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/surgicalneurologyint.com\/minimally-invasive-port-stent-surgery-re-purposing-a-balloon-expandable-covered-vascular-stent-for-minimally-invasive-resection-of-deep-cerebral-masses-report-of-4-first-in-human-stent-port-cases\/","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/minimally-invasive-port-stent-surgery-re-purposing-a-balloon-expandable-covered-vascular-stent-for-minimally-invasive-resection-of-deep-cerebral-masses-report-of-4-first-in-human-stent-port-cases\/","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,21]],"date-time":"2026-08-21T08:48:16Z","timestamp":1787302096000},"score":1,"resource":{"primary":{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/minimally-invasive-port-stent-surgery-re-purposing-a-balloon-expandable-covered-vascular-stent-for-minimally-invasive-resection-of-deep-cerebral-masses-report-of-4-first-in-human-stent-port-cases\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,21]]},"references-count":5,"alternative-id":["10.25259\/SNI_433_2026"],"URL":"https:\/\/doi.org\/10.25259\/sni_433_2026","relation":{},"ISSN":["2152-7806","2229-5097"],"issn-type":[{"value":"2152-7806","type":"electronic"},{"value":"2229-5097","type":"print"}],"subject":[],"published":{"date-parts":[[2026,8,21]]},"article-number":"481"}}
