Iodized Oil-Assisted Biopsy of Hepatic Space-Occupying Lesions Utilizing Hepatic Artery Catheter Protection

1

Iodized oil marking-guided biopsy enhances the diagnosis of hepatic space-occupying lesions by improving targeting and reducing bleeding risk.
2

The study involved 39 patients with suspected malignant hepatic lesions requiring pathological confirmation under hepatic artery catheter protection.
3

Ultrasound-guided biopsy is limited for small or deep lesions, while iodized oil marking provides a novel approach for better visualization.
4

The technique includes preoperative imaging, hepatic arterial catheterization, and post-embolization confirmation of iodized oil deposition.
5

Safety and efficacy were evaluated, with complications classified by the Clavien–Dindo system, ensuring comprehensive patient monitoring.
