Abstract
Objective To study the clinical features of ruptured aneurysms of anterior circulation. Methods The clinical data of 178 patients suffered from ruptured anterior circulation aneurysms were retrospectively analyzed. In the group, preoperative Hunt and Hess grade was Ⅰ in 59 cases, Ⅱ in 41, Ⅲ in 45, and Ⅳ-Ⅴ in 33. The pterional approach was used for microsurgery in all the cases, and 179 aneurysms were clipped successfully under the microscope. Results After the surgery, good outcome was achieved in 133 cases, mild disability in 25, severe disability in 11, and dead in 9. Conclusion Early surgery by clipping the aneurysms can avoid rehemorrhage. Active treatment is feasible to increase the survival rate of patients with grade Ⅳ or Ⅴ. To prevent intraoperative rupture of aneurysm can decrease the disability rate and mortality.
