Here, we describe a case of NF-1 complicated with a massive subcutaneous hematoma posing a risk of visual impairment for which rapid decompression and a subsequent less invasive approach result in a favorable outcome.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nA 40-year-old woman with NF-1 presented with a massive left subcutaneous temporal hematoma following a mild head contusion. Four days after hospitalization, the hematoma increased in size and severely compressed the left eye, prompting immediate hematoma removal to preserve visual function. Immediately after the hematoma removal, a superficial temporal arteriovenous fistula was found on the digital subtraction angiography and embolized by the endovascular procedure. Her visual acuity was preserved, and no bleeding recurrence was observed throughout the follow-up.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nSurgical hematoma removal followed by endovascular treatment was effective in preserving visual function. Since vessel fragility is characteristic of patients with NF-1, it should be kept in mind that vascular complications may lead to serious clinical outcomes. In certain NF-1 cases, less invasive treatments for vascular abnormalities may be preferable.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_471_2024","type":"journal-article","created":{"date-parts":[[2024,8,16]],"date-time":"2024-08-16T11:10:12Z","timestamp":1723806612000},"page":"289","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Traumatic
