Safety and accuracy of frameless electromagnetic-navigated (axiem)-guided brain lesion biopsies: a large single-unit study.
Acta neurochirurgica (2019) 161: 2 87¿5 259 3 https://doi.

1007/s00701-019-04093-y abstract: background: brain biopsies are required to establish a definitive histological diagnosis for brain lesions that have been identified on imaging in order to guide further treatment for patients.
Objective: various navigation systems are in use but little up to date evidence is available regarding the safety and accuracy of a frameless, electromagnetic technique to target brain lesions.
Methods: data was collected retrospectively on all patients that had brain biopsies at our institution from 01/01/2010 to 31/12/2017.
Operation notes, neuropathology reports, and clinical notes on electronic patient record were used to determine whether biopsy of adequate identifiable abnormal tissue was achieved, whether a definitive diagnosis was established, any adverse events occurred, and if a repeat biopsy was carried out.
Results three hundred seventy-one axiem(medtronic, minneapolis, usa)-guided brain tumor biopsies were performed in this 8-year period.
Three hundred forty-nine (94.
07%) procedures provided definitive tissue diagnosis, 22 (5.
93%) were non diagnostic; in 6 cases (1.
62%), repeat biopsy was performed and adverse events which caused clinical compromise were observed in 4 patients (1.
08%).
Conclusions the axiem is a fast, effective, and safe frameless and pinless neuronavigational system.
It offers a high degree of accuracy required for the establishment of a definitive diagnosis, permitting optimal further treatment, and thus improving patient outcomes.
Reported events: 1.
Three patients died from postoperative hematoma and cerebral edema in the region of the biopsy tract within 24 hours.
It was noted the patients had a diagnosis of glioblastoma multiforme iv.
2.
One patient died from new onset postoperative status epilepticus.
It was noted that the patient had diffuse b cell lymphoma.
