[Surgical treatment of unruptured cerebral aneurysms and complications in patients with ischemic cerebrovascular disease].
Patients who have unruptured intracranial aneurysms associated with ischemic cerebrovascular disease are a high-risk group for surgery. We have done clipping surgery in 15 patients among 40 with ischemic cerebrovascular disease. The criteria for surgery included an age below 65 years, CBF of more than 35 ml/100 g/min, and favorable ADL comparable to Rankin score 0-III. Two patients received simultaneous aneurysm clipping and superficial-middle cerebral artery anastomosis. Only one patient suffered from ischemia-related permanent neurological worsening, and one had direct optic nerve injury. Surgical mortality was 0%, and morbidity was 15%. There were two patients who had transient neurological worsening. These results suggest that surgical treatment of unruptured cerebral aneurysms is not contraindicated in patients with ischemic brain disease, but careful selection and careful perioperative management are mandatory for preventing surgical complications.
