Background:
Spinal cord ischemia (SCI) is a serious complication that can occur at the onset of aortic aneurysm (AA) or after AA surgery. SCI impairs ambulation in patients. However, there is a lack of evidence regarding ambulatory status and its associated factors.
Objectives:
To identify the ambulatory status of patients with SCI due to AA and/or AA surgery and sociodemographic and clinical characteristics factors associated with ambulatory status.
Methods:
A descriptive study using a retrospective medical record data was undertaken. Data were collected from the electronic health records of SCI patients resulting from AA or who underwent surgical intervention for AA from January 2009 through December 2021. We analyzed the data to determine the ambulatory status before discharge. The demographic and clinical characteristics of the patients were investigated using chi-square and Fisher's exact tests to identify factors associated with ambulatory status.
Results:
Among the 4,142 patients diagnosed with AA, 30 developed SCI. Of these 30 AA patients with SCI, 63.3 % were male. The median age was 70 years, ranging from 39 to 89 years. Six had SCI at the time of AA diagnosis. Among the subset of 2,994 patients who underwent aortic surgery, 24 developed SCI postoperatively. At discharge, two-thirds of the SCI patients with AA were unable to ambulate, and almost half were bedridden. The factors associated with ambulatory status were length of stay, neurogenic bladder, and pressure ulcers.
Conclusions:
Most patients with SCI due to AA and/or AA surgery are unable to walk before discharge. Length of stay, neurogenic bladder, and pressure ulcers were associated with poor ambulatory status. Older adults and those with medical comorbidities and complications are at particularly high risk for impaired ambulation.
