Abstract
Objective
To evaluate the effects of modified encephalo-duro-arterio-synangiosis (EDAS) on Moyamoya diseases (MMD) by single photon emission tomography (SPECT).
Methods
Thirty-six patients with MMD (29 with ischemic MMD and 7 with hemorrhagic MMD), admitted to our hospital from January 2011 to December 2013 and treated by modified EDAS, were chosen in our study; all the patients were followed up by SPECT, and the images changes before and after modified EDAS were compared.
Results
In the 36 MMD patients, 41 hemisheres were treated by modified EDAS; the total improvement rate was 56.1% (23/41), enjoying increased cerebral blood flow after EDAS; in ischemic MMD patients, the total improvement rate was 58.8% (20/34), while those was 42.9% (3/7) in hemorrhagic MMD patients.
Conclusion
The cerebral blood flow is improved obviously when MMD is treated by modified EDAS, especial on ischemic MMD patients.
