Clinical-Interventional debriefing analysis for all patients who underwent ultrasound-guided focal liver biopsy and developed hemorrhage requiring embolization. PVA=polyvinyl alcohol particles. AVF = Arterial-Venous fistula. PSA = Pseudoaneurysm

Patient	Angiography findings	Embolization materials	Catheter position	Result
1	AVF	100 μm PVA, microcoils	Segmental (focal / sub-selective not possible)	Effective
2	Extravasation	40–120 μm microspheres, PVA, microcoils	Segmental, lobar (focal / sub-selective not possible)	Effective
3	AVF, PSA	500–700 μm microspheres, microcoils	Focal sub-selective/subsegmental	Effective
4	AVF	300 μm PVA, microcoils	Focal sub-selective and segmental	Effective
5	AVF	300–500 μm PVA	Lobar	Effective
6	PSA, hypervascular tumor	50 μm PVA, microcoils	Focal sub-selective and subsegmental	Effective
7	Transient blush	Gelfoarr particles and slurry	Lobar	Effective
8	AVF, Extravasation	Microcoils	Focal sub-selective	Effective
9	Transient blush	Gelfoam particles	Sectoral	Post-embolization transfusion was given for hemoglobin drop by 1 point.
10	Hepatic arterial-biliary fistula	100–300 μm microspheres, 100 μm PVA	Lobar	Persistent slow bleeding for 8 days after embolization.
11	None	50 μm PVA	Lobar	Effective
12	Extravasation	Coils, 300–500 μm PVA	Sectoral	Effective
