Study on Hemodynamics and Hyperperfusion Syndrome in CICAO Patients Post-Bypass Surgery
New Information: This study investigates the hemodynamic changes in the brain’s surgical area and the risk of hyperperfusion syndrome (HPS) in patients with chronic internal carotid artery occlusion (CICAO) undergoing superficial temporal artery-middle cerebral artery (STA-MCA) bypass surgery. It utilizes intraoperative indocyanine green videoangiography (ICGV-FLOW 800) and postoperative CT perfusion to assess these changes.
Importance: Understanding hemodynamic changes and identifying potential risk factors for HPS are crucial for improving surgical outcomes in CICAO patients.
Contribution to Literature: The study provides evidence that ICGV-FLOW 800 can accurately record hemodynamic changes in cortical vessels during STA-MCA bypass surgery. It also identifies increased area under the time curve (AUCTTP) of the distal MCA and shorter time to peak (TTP) of the cortical blood capillary as potential risk factors for HPS.
Results: Among 77 patients, 14 developed HPS post-surgery. The HPS group showed a significantly larger AUCTTP of DMCA (T = -3.301, p = 0.004) and shorter TTP of CBC (T = -2.929, p = 0.005) compared to the non-HPS group. Multivariate logistic regression analysis indicated that a larger AUCTTP of DMCA is an independent risk factor for HPS (OR = 3.024, 95%CI 1.390-6.578, p = 0.0050).
