Abstract:

Objective

To investigate the clinical characteristics and risk factors of delayed cerebral hyperperfusion syndrome (dCHS) after decompressive hemicraniectomy (DHC) for massive cerebral infarction (MCI).

Methods

A retrospective analysis of 44 patients with MCI who underwent DHC at Ningbo Medical Center Lihuili Hospital from June 2016 to September 2020 was performed. The patients were divided into three groups: dCHS group (n = 10), acute cerebral hyperperfusion syndrome (aCHS) group (n = 14) and non-CHS group (n = 20), based on whether CHS occurred and when it occurred. The general data of the three groups were compared, and the risk factors related to dCHS were analyzed by multivariate Logistic regression.

Results

There were significant differences in middle cerebral artery (MCA) occlusion, hemorrhagic transformation, and reoperation after hemorrhagic transformation among these three groups (χ2 = 17.720, 24.144, 18.324, all P < 0.05). The results of multivariate Logistic regression analysis showed that delayed recanalization after MCA occlusion [odds ratio (OR) = 16.750, 95% confidence interval (CI) (1.111, 252.468), P = 0.042] and hemorrhagic transformation [OR = 10.206, 95%CI (1.095, 95.123), P = 0.041] were independent risk factors for the occurrence of dCHS.

Conclusion

Delayed recanalization after MCA occlusion and hemorrhagic transformation are independent risk factors for dCHS in patients with MCI undergoing DHC.
