thoracic complications spine level marker 179 gold fiducialAbstract
BACKGROUND AND PURPOSE: Wrong-level spinal surgery, especially in the thoracic spine, remains a challenge for a variety of reasons related to visualization, such as osteopenia, large body habitus, severe kyphosis, radiographic misinterpretation, or anatomic variation.
Preoperative fiducial marker placement performed in a dedicated imaging suite has been proposed to facilitate identification of thoracic spine vertebral levels.
In this current study, we report our experience using image-guided percutaneous gold fiducial marker placement to enhance the accuracy and safety of thoracic spinal surgical procedures.
MATERIALS AND METHODS: A retrospective review was performed of all fluoroscopy- or CT-guided gold fiducial markers placed at our institution between January 3, 2019, and March 16, 2022.
A chart review of 179 patients was performed detailing the procedural approach and clinical information.
In addition, the method of gold fiducial marker placement (fluoroscopy/CT), procedure duration, spinal level of the gold fiducial marker, radiation dose, fluoroscopy time, surgery date, and complications (including whether wrong-level surgery occurred) were recorded.
RESULTS: A total of 179 patients (104 female) underwent gold fiducial marker placement.
The mean age was 57 years (range, 12–96 years).
Fiducial marker placement was performed by 13 different neuroradiologists.
All placements were technically successful without complications.
All 179 (100%) operations were performed at the correct level.
Most fiducial markers (143) were placed with fluoroscopy with the most common location at T6–T8.
The most common location for placement in CT was at T3 and T4.
CONCLUSIONS: All operations guided with gold fiducial markers were performed at the correct level.
There were no complications of fiducial marker placement.
