Résumé
To report the utility of real-time arteriography-directed percutaneous MWA (rad-pMWA) in a hybrid angiography-computed tomography (Angio-CT) suite to treat small or inconspicuous hepatic tumors on non-contrast CT. This single-center retrospective cohort included 15 consecutive patients who underwent rad-pMWA (6 HCC, 4 mCRC, 4 NET, and 1 cholangiocarcinoma). The median longest axial diameter of treated tumors was 1.7 (range: 1.4-6.0) cm. Technical success, contrast use, procedure-related complication, and initial treatment response were recorded. Technical success was achieved in 15/15 (100%) as shown by no residual enhancement on catheter-directed CT-angiography at the conclusion of the procedure. Average contrast volume use was 63.1 (SD: 29.1) ml. No major arterial access-related complication or residual tumor was noted. Complete ablation rate was 14/14 (100%) at initial 6-8-week follow-up. Local disease progression occurred in one patient during follow-up. Rad-pMWA using Angio-CT is safe and effective for improving tumor visibility and operator convenience. Tumors can be localized with low contrast dosage and ablated with high efficacy with immediate real-time evaluation of the ablation cavity.
