Event Description
Citation: bassaganyas-vancells, et al. ¿combined use of 5-aminolevulinic acid and intraoperative low-field magnetic resonance imaging in high-grade glioma surgery. ¿ world neurosurgery. Oct. 2019;130:e206-e212. Https://doi. Org/10. 1016/j. Wneu. 2019. 06. 029 abstract: objective: we sought to assess the impact of 5-aminolevulinic acid (5-ala) and low-field intraoperative magnetic resonance imaging (imri) on the extent of resection of high-grade gliomas (hggs). Results are compared with those obtained when using 5-ala and imri separately. Methods: we retrospectively included patients with an hgg eligible for gross total resection (gtr) from january 2013 to january 2018. Patients were included according to 5-ala surgical guidance (5a-group), imri (imri-group), or both (5a-imri-group). Surgical variables were registered, and presurgical and postsurgical radiologic and clinical variables were analyzed. Extent of resection greater or equal to 90%, complications, and new permanent neurologic deficit were compared using the chi-squared and analysis of variance tests. Other variables studied were mortality, average hospital stay, surgical time, and karnofsky performance scale status before and after surgery. Results: most of the 118 procedures carried out were in men (59. 2%). The mean age was 58 years. Sixty patients (50. 8%) were operated on using exclusively 5-ala assistance (5a-group), 19 (16. 1%) using imri (imri-group), and 39 (33%) combining both techniques (5a-imri-group). There were no statistically significant differences among 3 groups regarding extent of resection greater or equal to 90% (73% 5a, 73. 7% imri, 71. 8% 5a-imri, p
=
0. 94); complication rates (18. 3% 5a, 5. 3% imri, 7. 7% 5a-imri, p
=
0. 17); new or worsening of preexisting neurologic deficit at 1-month follow-up (13. 3% 5a, 10. 5% imri, 15. 4% 5a-imri, p
=
0. 26); average hospital stay in days (9. 5 5a, 6. 4 imri, 7. 6 5a-imri, p
=
0. 18); karnofsky performance scale; nor surgical time in minutes (212. 4 5a, 187. 9 imri, 201. 4 5a-imri, p
=
0. 13). Conclusions: in our experience, combined use of imri and 5-ala does not improve the studied variables when compared with those technologies when used separately, even though a slight tendency of a superior effectiveness is observed when using imri individually. Reported events: 11 patients in the 5a-imri group had re-operations. 8 patients in the 5a-imri group had an occurrence of a new neurologic deficit or worsening of preexisting deficit in the immediate postoperative period. 6 of these patients had these deficits remaining one month post-operatively. 1 patient in the 5a-imri group had superficial infection of the surgical wound. 1 patient in the 5a-imri group had meningitis (listeria). 1 patients in the 5a-imri group had an epidural hematoma.
