Comparative Effectiveness of Nonoperative Management in Large and Small Acute Traumatic Subdural Hematomas

Patients aged >80 years frequently have intracranial meningiomas. In the present study, we have discussed the pathological features, comorbidities, and surgical complications for this age group from a surgical series and literature review.In the present study, we reviewed a surgical series of 354 intracranial meningiomas and compared the oldest age group (age, ≥80 years) of 17 patients with 73 patients aged 70–79 years and 264 patients aged <70 years. From a literature review, we selected 10 studies of meningiomas in patients aged ≥80 years. The analyzed factors included sex, meningioma location, World Health Organization grade, Ki-67 MIB1, progesterone receptor expression, comorbidities, American Society of Anesthesiologists class, Karnofsky performance scale score, postoperative complications, and death.Patients aged ≥80 years had had higher rates of World Health Organization grade II meningioma, higher rates of Ki-67 expression of >4% and <20%, and progesterone receptor expression <15%. Of the postoperative complications, only neurological deficits and acute bronchopneumonia were significantly more frequent in patients aged ≥80 years. The incidence of intracerebral hematoma, lung embolism, acute heart ischemia, and death were not significantly different between the patients aged ≥80 years and those aged 70–79 years and <70 years.Patients aged ≥80 years must be considered a true elderly group with higher rates of comorbidities. The very old age is not a limitation to surgery; however, careful patient selection is necessary. In addition, for the oldest age group, the surgical decision should not be delayed because of advancing age.
