The EASYXâ„¢ Liquid Embolic is a new injectable, precipitating polymeric agent for the obliteration of vascular spaces through direct puncture or catheter access performed under X-ray guidance. The embolic liquid is an iodinized Polyvinyl Alcohol (PVA) Polymer ether. Iodine groups are covalently grafted to the PVA polymer backbone, whereby a stable nondegradable polymer with the desired features is created. The resulting polymer is dissolved in Dimethyl Sulfoxide (DMSO). EASYXâ„¢ is CE-marked since December 2016 and has been used in humans a few time for type II endoleaks, portal vein and varicocele (<10 cases at the date of submission). The purpose of this study is to evaluate the safety and efficacy of EASYXâ„¢ embolization liquid for the percutaneous treatment of vascular lesions, i.e. embolization of varicocele, type II endoleaks, portal vein before surgery, active peripheral bleeding or angiomyolipoma (AML).

| Safety:Total number of per-procedure Serious Adverse Events (SAE) for the safety | Expected and unexpected per-procedure (SAE) related to the EASYXâ„¢ use (imputability "certain" or "probable") | one day |
| Efficacy for type 2 endoleaks embolization | Percentage of clinical success. The clinical success of type II endoleaks embolization is defined as the stability or reduction of aneurysm's both anterioposterior and transverse diameters assessed on CT-scan at 6 months compared to baseline (4mm threshold). | 6 months |
| Efficacy for portal vein embolization | Percentage of clinical success before ablation for portal vein embolization. The clinical success of portal vein embolization is defined as the growth ≥15 % of the remnant liver assessed on presurgical CT-scan compared to baseline | Before ablation |
| Efficacy for varicocele embolization | Percentage of clinical success for varicocele embolization The clinical success of varicocele embolization is defined as the absence of reflux on ultrasound Doppler at one month follow-up. | 1 month |
| Efficacy for angiomyolipoma embolization | Percentage of clinical success for angiomyolipoma embolization. The clinical success of angiomyolipoma embolization is defined as the reduction >10% of at least one diameter on MRI or CT-scan at 3 months follow-up compared to baseline | 3 month |
| Efficacy for active bleeding embolization | Percentage of clinical success for active bleeding embolization The clinical success of active bleeding embolization is defined as the complete occlusion of the target vessel assessed by angiography during the index procedure |
