Official Description

Implanting and securing cerebral thermal perfusion probe, including twist drill or burr hole, to measure absolute cerebral tissue perfusion

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 0077T involves the implantation and securing of a cerebral thermal perfusion probe. This probe is inserted through a twist drill or burr hole created in the skull. The primary purpose of this procedure is to measure the absolute cerebral tissue perfusion, which refers to the blood flow within the brain tissue. Accurate measurement of cerebral perfusion is critical, particularly in clinical scenarios such as severe head injuries, where monitoring blood flow can provide essential information regarding the patient's condition and guide further treatment decisions. The use of a thermal perfusion probe allows for real-time assessment of cerebral blood flow, which is vital for managing patients with compromised brain perfusion and ensuring optimal outcomes.

1. Indications

The procedure is indicated for specific clinical scenarios where monitoring cerebral blood flow is essential. The following conditions may warrant the implantation of a cerebral thermal perfusion probe:

  • Severe Head Injury The procedure is commonly performed in patients who have sustained significant head trauma, where assessing cerebral perfusion can help in evaluating the extent of brain injury and guiding treatment.
  • Cerebral Ischemia In cases where there is a concern for reduced blood flow to the brain, this procedure can assist in monitoring and managing the patient's condition.
  • Neurological Monitoring Patients requiring close observation of cerebral perfusion due to various neurological conditions may also be candidates for this procedure.

2. Procedure

The procedure for implanting and securing a cerebral thermal perfusion probe involves several critical steps to ensure accurate placement and functionality. The following outlines the procedural steps:

  • Step 1: Preparation The patient is positioned appropriately, and the area of the skull where the probe will be inserted is cleaned and sterilized to minimize the risk of infection. Anesthesia may be administered to ensure the patient's comfort during the procedure.
  • Step 2: Creating the Access Point A twist drill or burr hole is utilized to create an opening in the skull. This step is crucial as it provides access to the brain tissue for the insertion of the thermal perfusion probe.
  • Step 3: Inserting the Probe The cerebral thermal perfusion probe is carefully inserted through the created hole. The probe must be positioned accurately to ensure it measures the blood flow within the targeted area of the brain tissue.
  • Step 4: Securing the Probe Once the probe is in place, it is secured to prevent any movement that could affect the accuracy of the measurements. This may involve suturing or using other fixation methods to ensure stability.
  • Step 5: Monitoring and Calibration After securing the probe, it is connected to monitoring equipment that will measure cerebral perfusion. Calibration may be performed to ensure that the readings are accurate and reliable.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any complications that may arise from the implantation of the cerebral thermal perfusion probe. This includes observing for signs of infection at the insertion site, monitoring neurological status, and ensuring that the probe is functioning correctly. Patients may require imaging studies to assess the placement of the probe and the condition of the brain. Recovery time can vary depending on the patient's overall health and the complexity of the procedure, but close monitoring is essential to ensure optimal outcomes and address any issues promptly.
