Abstract
Long-term survival and acute kidney injury during hospitalization after major neurosurgical procedure
Highlights
Acute kidney injury (AKI) during hospitalization after major surgical procedures is a risk factor for short-term mortality [1,2]
Patients were categorized by type of operative procedure or primary condition as follows: spinal surgery (SS); vascular surgery (VS); craniotomy for tumor (CT); craniotomy for non-tumor surgery (CNT); and patients with intracerebral hemorrhage (ICH)
The prevalence of AKI during hospitalization was dependent on the type of surgery, with the highest prevalence being among ICH patients (n=64, 17%) and the lowest among patients who underwent a non-tumor craniotomy (n=18, 6%) (Table 2)
Summary
Acute kidney injury (AKI) during hospitalization after major surgical procedures is a risk factor for short-term mortality [1,2]. Several studies have reported a higher prevalence of RIFLE-defined AKI in various patient populations, and confirmed the association of less severe AKI with short-term mortality,[4,7,8] few studies have focused on AKI in the cohort of neurosurgical patients[9,10]. Several studies have reported, that RIFLEdefined AKI is associated with a significant risk for long-term mortality in several different cohorts including large cohort of surgical patients as demonstrated in our previous study[11]. This association may vary with the type of surgery, and studies in more homogenous patient populations may be warranted[12]
