About this trial

The goal of this randomized clinical trial is to assess the benefit of early resumption versus late resumption of oral anticoagulation medication in adults with atrial fibrillation undergoing surgery for chronic subdural hematoma. The main questions it aims to answer are:

* Does anticoagulation resumption 5 days after surgery as compared to 30 days after surgery result in fewer thromboembolic complications, without increasing the risk for bleeding? * Does anticoagulation resumption 5 days after surgery as compared to 30 days after surgery affect the risk of reoperation, functional outcome, mortality, and healthcare use?

Researchers will compare early anticoagulation resumption (5 days) and late anticoagulation resumption (30 days) after chronic subdural hematoma surgery.

Participants will either resume the medication 5 days or 30 days after the surgery. The participants will be followed up for 3 months after the surgery.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age ≥18 years.

Patients with a symptomatic unilateral or bilateral CSDH requiring burr-hole evacuation with drainage (CSDH is predominantly hypodense or isodense on imaging [CT/MRI]; clinical symptoms attributable to the CSDH; patients with bilaterally operated CSDHs will be treated with the same protocol on both sides and analyzed as a single study participant).

Patients that are on an oral anticoagulation medication due to permanent, persistent or paroxysmal spontaneous atrial fibrillation previously known

Randomization done within 4 days of the surgery

Disqualifiers

Intraoperative or immediate postoperative hemorrhagic complication

CSDH requiring surgical treatment other than burr-hole evacuation (e.g. craniotomy)

Prior CSDH surgery within 12 months

Cerebrospinal fluid shunt

Treatments tested in this trial

  • Early Resumption of Oral Anticoagulation Therapy

    Drug

    The patient's prescribed anticoagulant therapy for atrial fibrillation is resumed on the 5th postoperative day following burr-hole surgery for chronic subdural hematoma. This early resumption strategy is compared to the standard practice of resuming anticoagulation therapy on the 30th postoperative day.

  • Late Resumption of Oral Anticoagulation Therapy

    Drug

    The patient's prescribed anticoagulant therapy for atrial fibrillation is resumed on the 30th postoperative day following burr-hole surgery for chronic subdural hematoma. This standard resumption strategy is compared to the early approach of resuming anticoagulation therapy on the 5th postoperative day.

Trial outcomes

Primary outcomes

1

Rate of composite outcome of vascular events

Rate of the composite outcome that combines thromboembolic events (ischemic stroke, systemic embolism), hemorrhagic events (intracranial hemorrhage, major extracranial bleeding), and vascular death.

Time frame
90 days

Secondary outcomes

1

Rate of different components of the primary composite outcome

Separation of the components of the primary composite outcome (thromboembolic, hemorrhagic, vascular death).

Time frame
90 days
2

Rate of patients with favorable functional outcome

Assessed using the modified Rankin Scale (mRS), which ranges from 0 (no symptoms) to 6 (death).

Time frame
90 days
3

Rate of reoperation

Reoperation for the initially treated chronic subdural hematoma.

Time frame
90 days
4

Rate of all-cause mortality

Time frame
90 days and 12 months
