{"title":"The role of intervention timing and treatment modality in visual recovery following pituitary apoplexy: a systematic review and meta-analysis.","authors":"Nolan J Brown, Saarang Patel, Julian Gendreau, Mickey E Abraham","doi":"10.1007/s11060-024-04717-z","DOIUrl":"https://doi.org/10.1007/s11060-024-04717-z","url":null,"abstract":"<p><strong>Introduction: </strong>Pituitary apoplexy has historically been considered an emergent condition that necessitates surgical intervention when there is acute symptomatic onset. This potentially serious condition often occurs in the setting of an underlying adenoma, cystic lesion, or other sellar mass. When these mass lesions hemorrhage within the confined space of the sella turcica, the pituitary gland is subjected to hemorrhagic ischemia. Furthermore, critical neurovasculature in close proximity to the sella can sustain collateral damage. In the present study, we investigate whether early versus delayed surgical intervention (in terms of three timelines: before versus after 48 h, 72 h, and 7 days, respectively) results in differences in visual outcomes for patients experiencing pituitary apoplexy with acute onset neurological and/or neuro-opthalmic symptoms. Furthermore, we compare the efficacy of surgical decompression versus expectant management of this condition.</p><p><strong>Methods: </strong>Accordingly, we queried the PubMed, Scopus, and Embase databases in adherence to PRISMA guidelines. Quantitative meta-analysis was performed according to the Mantel-Haenszel method and forest plots were generated using Review Manager v5.4. P-values < 0.05 were defined as the threshold for statistical significance.</p><p><strong>Results: </strong>Twenty-nine studies remained eligible for review following initial search and screen, including 16 studies describing the role of intervention timing and 15 studies comparing intervention modality. Most patients presented with a visual deficit, and all patients underwent surgery - most commonly via the endoscopic endonasal (EEA) approach. Two hundred and twenty patients were included in the sub-analysis for the 7-day cutoff point. Furthermore, 81 patients underwent surgical decompression of the sella prior to 48 h, and 32 patients underwent surgical decompression between 48-72 h following presentation. Almost all patients exhibited improved vision post-decompression, including 19/19 patients (100%) in the post-72-h cohort. On meta-analysis using the Mantel-Haenszel method, there was a significant difference in vision outcomes in favor of patients who underwent surgical decompression before 7 days as compared to after seven days (OR 5.88, 95% CI [1.77, 19.60], I<sup>2</sup> = 0%, p < 0.01). In a separate sub-analysis, there was a total of 288 patients across 15 studies comparing surgical versus conservative management of pituitary apoplexy. These management options proved equivocal on meta-analysis (p > 0.05).</p><p><strong>Conclusion: </strong>In the present study, timing of surgical intervention for pituitary apoplexy was predictive of visual function recovery only at the 7-day timepoint, as has been reported by previous studies. Ultimately, this suggests that pituitary apoplexy involving severe visual deficits or altered mental status is best addressed within the first seven days post-presentation, ","PeriodicalId":16425,"journal":{"name":"Journal of Neuro-Oncology","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142583190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
