Objectives: 1/ To describe the dinical features and imaging of SAH due to ruptured MCA aneurysms. 2/ To comment on the results of treatment of SHA due to ruptured MCA aneurysms. Subjects and Methods: prospective cross-sectional study of 54 patients who suffered from SHA due to ruptured MCA aneurysms and admitted to the Bach Mai Hospital from 1/2009 to 12/2010. Results and conclusions: There were 26 females and 28 males, the mean age was 56 years.

Approximately 74 percent of aneurysms neck size were small and medium. The average size of aneurysms was 6.0mm, most MCA aneurysms occurred at the bifurcation 79.6 percent, right 55.6 percent, left 37 percent, both sides 7.4 percent. Treatment: surgical treatment 48.1 percent, endovascular treatment 31.5 percent, medicine treatment 13 percent, good recovery 55.6 percent, moderate sequelae 18.5 percent, severe sequelae 9.2 percent, vegetable 1.9 percent and mortality 14.8 percent.
