Outcome Measures

Primary Outcomes (1)

  • Effective Aneurysm Clipping (no residual cerebral aneurysm)

    All patients will be submitted to a post operative angiography to asses the presence of residual cerebral aneurysm after clipping.

    3 months after surgery

Secondary Outcomes (5)

  • All Cause Mortality

    1 year

  • Neurological Outcome

    1 year

  • Cosmetic Outcome

    1 year

  • Surgical Safety assessed by number and description of Surgical Complications (infection rate, postoperative epidural/ contusional hematomas, number of reoperations, need of blood transfusion)

    1 year

  • Early Hospital Discharge

    15 days

Other Outcomes (1)

  • Quality of Life

    15 days, 3 months, 6 months and 1 year

Study Arms (3)

Transpalpebral Approach

EXPERIMENTAL

Aneurysm Clipping - Patients will be submitted to a Transpalpebral Approach to Unruptured Anterior Circulation Aneurysm and they will be discharged from the hospital on the next day.

Procedure: Aneurysm Clipping

NanoPterional Approach

EXPERIMENTAL

Aneurysm Clipping - Patients will be submitted to a Modified MiniPterional Approach (Nanopterional) to Unruptured Anterior Circulation Aneurysm and they will be discharged from the hospital on the next day.

Procedure: Aneurysm Clipping

Classical Pterional Craniotomy

SHAM COMPARATOR

Aneurysm Clipping - Patients will be submitted to a Classical Pterional Approach to Unruptured Anterior Circulation Aneurysm and they will be discharged from the hospital 4-5 days after the procedure.

Procedure: Aneurysm Clipping

Interventions

All Patients will be submitted to a surgical intervention in order to clip their unruptured brain aneurysm

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with the diagnosis of incidental unruptured cerebral aneurysms (4mm to 2cm)

You may not qualify if:

  • Patients who do not have adequate family care during the immediate post-operative period (the patient's family must commit to stay with the patient in the first five days after hospital discharge)
  • Patients who are unable to communicate by telephone
  • People with cardiovascular disease, liver or kidney failure.
  • Pregnant women or breastfeeding
  • Patients with coagulation abnormalities
  • Patients with High Surgical Risk evaluated by different risk scores (ASA, AHA, Goldman, Detsky)
