Image-guided percutaneous bone biopsy with a simulated van sonnenberg removable hub system

Area of Science:

• Radiology
• Interventional Radiology
• Oncology

Background:

• Percutaneous bone biopsy is crucial for diagnosing bone lesions.
• Image guidance enhances accuracy and safety in bone biopsy procedures.

Purpose of the Study:

• To evaluate the success and complication rates of image-guided percutaneous bone biopsy using a simulated Van Sonnenberg removable hub system.

Main Methods:

• Retrospective analysis of 28 percutaneous bone biopsies performed over 3.5 years.
• Utilized a simulated Van Sonnenberg removable hub system with a cut-out Chiba needle hub for guidance.
• Employed fluoroscopy or CT for guidance, with core and aspiration biopsy or core biopsy alone.

Main Results:

• Diagnostic material was obtained in 89% of cases (48% infection, 22% benign, 19% malignant).
• Combined core and aspiration biopsy showed higher diagnostic accuracy than core biopsy alone.
• No false positive/negative diagnoses or serious complications (neurological deficits, bleeding, organ injury) were observed.

Conclusions:

• The simulated Van Sonnenberg removable hub system is a safe and effective technique for percutaneous bone biopsies.
• This system is particularly advantageous for accessing deep-seated lesions, such as those in the vertebrae.
• The procedure demonstrates a favorable safety profile compared to existing literature data.
