Brief Summary
Project Summary: Retrospective Cohort Study
- 1.Core ObjectiveThe primary goal is to determine if the volume of Hydroxyethyl Starch (HES) 130/0.4 (specifically Voluven® or Volulyte®) administered during the removal of giant meningiomas (tumors \> 5 cm) increases the risk of postoperative complications.
- 2.Research Question
- 3.Outcomes Primary: Incidence of re-bleeding at the tumor bed requiring re-operation within 48 hours Secondary: New-onset postoperative AKI within 7 days (defined by KDIGO criteria)

Outcome Measures
Primary Outcomes (1)

The cumulative incidence of re-bleeding and required re-craniotomy within 48 hours
7 days
Secondary Outcomes (1)

Study Arms (2)
Exposed Group
Patients who received HES during surgery
Non-Exposed Group
Patients who did not receive HES (received only crystalloids or other fluids).
Interventions
did and did not receive HES (received only crystalloids or other fluids)
Eligibility Criteria
Adult patients diagnosed of giant meningiomas, diameter of at least 5 cm. They were scheduling for craniotomy during 2016-2024. Withdrawal Criteria: There are no specific withdrawal criteria listed for this study. Ethical Consideration: Since this is a retrospective study using existing hospital electronic records, individual informed consent is not required.
You may qualify if:
- Diagnosis: Patients must be diagnosed with a meningioma. Tumor Size: The tumor must be classified as "giant," defined as having a diameter of 5 cm or larger as seen on a CT scan.
- Surgery Type: Patients must have undergone a craniotomy to remove the tumor. Timeframe: The surgery must have occurred between the years 2016 and 2024
You may not qualify if:
- Recurrent Cases: Patients with a recurrent meningioma (rather than a first-time surgery).
- Emergency Cases: Patients requiring an emergency craniotomy. Pregnancy: Any patient who is pregnant. Major Complications: Patients who experienced cardiac arrest during the surgery.
