Safety and efficacy of microsurgery for complex cranial pathologies in the ultra-geriatric population.

OBJECTIVE

The global increase in the "ultra-geriatric" population (aged 80 years and older) has led to higher demand for neurosurgical procedures in this vulnerable population. The objective was to evaluate the safety and efficacy of advanced microsurgical procedures on ultra-geriatric patients, in our modern era of neurosurgery, anesthesiology, and advanced medical care.

METHODS

The study examined 66 complex cranial procedures, performed on 65 ultra-geriatric patients, who constituted 3.8% of the 4461 consecutive neurosurgical procedures performed by a single neurosurgeon over 14-years in a tertiary care university hospital. Excluded from this study were intra- or extra-axial spontaneous hematomas or traumatic brain injuries, infections, biopsy-only cases and carotid endarterectomies.

RESULTS

The most common indication for surgery for the 66 complex cranial procedures were meningiomas (23.9%), followed by gliomas (17.9%), and metastatic brain tumors (17.9%). Postoperative complications occurred in seven procedures (10.60%). No patient deaths were directly caused by intra- or postoperative events, and only one 30-day mortality occurred. All deceased patients had a statistically significant higher American Society of Anesthesiologists (ASA) class (p = 0.024). However, there was no significant correlation between ASA class and modified Rankin scale at discharge (p = 0.238).

CONCLUSION

With the aging global population and increasing life expectancy, the number of ultra-geriatric patients with complex pathologies seeking advanced microsurgical treatment is growing. Therefore, neurosurgeons are confronting a growing number and variety of complex pathologies in ultra-geriatric patients in their daily practice. Regardless of advanced age, microsurgery provides safe and effective treatment, with age alone not being a barrier to proper neurosurgical treatment when other risk factors are adequately modified.
