E-056 Current applications of oct in neurointerventional angiography: a retrospective cross-sectional observational analysis
Abstract
Introduction Optical coherence tomography (OCT) is a novel intraluminal imaging modality that uses optical backscattering to produce cross-sectional images of tissue. The technique has already proven useful in the coronary vasculature for evaluation of plaques, stent-vessel interactions, dissections and intimal healing. However, there is limited data regarding the current applications of OCT in cerebrovascular imaging. Methods We performed a retrospective analysis of the Nationwide Inpatient Sample (NIS) between 2009–2015. Patients with an ICD-9-CM procedure code indicating use of OCT (38.25) and an ICD-9-CM diagnosis code indicating either presence of an intracranial aneurysm/SAH (437.3 or 430), carotid/vertebrobasilar/intracranial atherosclerosis with or without associated cerebral infarction (433.xx or 434.xx), or carotid/vertebrobasilar arterial dissection (443.21 or 443.24) were included. Primary diagnosis codes, primary procedure codes, hospital region, hospital teaching status, rate of iatrogenic neurologic injury, and time to use of OCT were evaluated in an effort to identify current inpatient OCT practices in neurointerventional angiography. Results 7 patients in the NIS were identified as having undergone OCT for a cerebrovascular pathology between the years of 2009–2015. Average age was 71.3 years. 2 patients were female and only 28% were elective admissions. 4 patients were discharged home, 2 would be discharged to a long-term care facility and 1 patient would…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 7 participants or records.
