Official title

Study on the Effect of Ultra-early Autologous Cranioplasty on Neurological Function Recovery: a Multicenter, Prospective, Open-label, Endpoint-blinded, Randomized Controlled Study

Overview

To compare the neurological recovery and complication rate of autogenous cranioplasty(CP) within 6 weeks after decompressive craniectomy (DC) with that of autogenous cranioplasty within 3\~6 months after DC.

Detailed description

Objective:

To compare the neurological recovery and complication rate of autogenous cranioplasty(CP) within 6 weeks after decompressive craniectomy (DC) with that of autogenous cranioplasty within 3\~6 months after DC.

Design:

This study is a multi-center, prospective, randomized controlled, open-label trial.

Interventions:

Intervention measures were the time point of cranioplasty: within 6 weeks after decompressive craniectomy VS 3-6 months after decompressive craniectomy.

Interventions

  • Procedure operation opportunity-within 6 weeks after the DC operation.
    The autologous skull repair surgery will be completed within 6 weeks after the DC operation.
  • Procedure operation opportunity-within 90 to 180 days after the DC operation.
    The autologous skull repair surgery should be completed within 90 to 180 days after DC.

Primary outcome measures

  • modified Rankin Scale (mRS) 0-2 [Time frame: at 180 (± 7) days]
Secondary outcome measures (11)
  • mRS≤2 and mRS ≤3 [Time frame: 90 (±7) days after CP]
  • mRS ≤3 [Time frame: 180 (±7) days after CP]
  • Mini-Mental State Examination (MMSE) score [Time frame: 90 days (±7 days) and 180 days (±7 days) after CP surgery]
  • Glasgow Outcome Score (GOS) [Time frame: 90 days (±7 days) and 180 days (±7 days) after CP surgery]
  • hydrocephalus or Cerebrospinal fluid shunt surgery rate [Time frame: 90 days (±7 days) and 180 days (±7 days) after CP surgery]
  • Total medical expenses (excluding materials) [Time frame: At the time of discharge from CP, 90 (±7) days after CP-CP and 180 (±7) days after CP-CP at discharge]
  • Complications related medical expenses [Time frame: At the time of discharge from CP, 90 (±7) days after CP-CP and 180 (±7) days after CP-CP at discharge]
  • Incidence of infection, poor healing, and subcutaneous effusion [Time frame: 90 days (±7 days) and 180 days (±7 days) after CP surgery]
  • The incidence rate of intracranial hemorrhage [Time frame: 90 days (±7 days) and 180 days (±7 days) after CP surgery]
  • incidence of epilepsy [Time frame: 90 days (±7 days) and 180 days (±7 days) after CP surgery]
  • incidence of reoperation [Time frame: 90 days (±7 days) and 180 days (±7 days) after CP surgery]
