Volumetric analysis using contrast-enhanced computed tomography was performed at a median of 25 days (PHVE) and 31 days (PVE) after embolization (P = .011). Primary outcome was FLR absolute hypertrophy (FLRabh). Multivariable linear regression including interaction terms was used to identify predictors of FLRabh. Adverse events were graded using the Society of Interventional Radiology (SIR) classification.Results: PHVE achieved significantly greater FLRabh (51.3% vs 27.0%, P < .001), degree of hypertrophy (13.4% vs 10.1%, P = .01), and kinetic growth rate (4.2 vs 2.9 %/wk, P = .001) compared with PVE. Resection rates were higher in the PHVE group (95.2% vs 76.5%, P = .008), with fewer tumor progressions during follow-up (3.2% vs 14.7%, P = .049). Multivariable analysis confirmed PHVE as an independent predictor of greater FLR hypertrophy, particularly in patients with lower baseline FLR volumes. One adverse event occurred in each group (SIR Grades 1 and 3).Conclusions: PHVE induces greater liver hypertrophy and is associated with lower tumor progression during the hypertrophy interval, supporting its role as an effective and safe option for surgical preparation in HCC with limited FLR.","PeriodicalId":49962,"journal":{"name":"Journal of Vascular and Interventional Radiology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144994210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study also assessed the radiopacity of the Onyx after a 1-minute mixing time.Materials and methods: Embolization using EVOH alone or in combination with coils/plugs was performed on large-vessel, small-vessel, and very-small-vessel (3-5 mm, 1-3 mm, and <1 mm in diameter, respectively) targets in the peripheral vasculature of Yucatan miniature pigs. Multiple formulations of EVOH were used. Angiography at 1, 3, and 12 months was used to assess embolic migration and vessel occlusion. Pathological evaluations were performed to assess the biological response to Onyx-mediated embolization.Results: Angiography demonstrated that the radiopacity of EVOH was sufficient for control during deployment in 98.2% of the procedures. Microcatheter removal was successful in all cases, and there was minimal migration of EVOH after delivery. Pathological findings indicated no significant tissue response or vessel trauma after embolization, and the occlusive material (consisting of EVOH, thrombus, and fibrotic tissue) evolved over time. The inflammatory response was minimal to mild, and vessel wall injury was observed in some cases. Complete to near-complete occlusion was achieved at every embolization site at the time of follow-up, although histologic evidence of recanalization was observed in 59.3% of the treated vessels.Conclusions: The study demonstrated the effectiveness of EVOH as an embolic agent in the peripheral vascular system with adequate radiopacity, minimal adverse effects, and acceptable long-term histologic outcomes in a swine model.","PeriodicalId":49962,"journal":{"name":"Journal of Vascular and Interventional Radiology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144994246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data collected included patient demographics, age of kidney transplant at biopsy, number of cores sampled, serum creatinine levels, medication use, and hemorrhagic adverse events (AEs). AEs were graded using the Society of Interventional Radiology (SIR) classification system. Outcomes were analyzed on the basis of graft age at the time of biopsy.Results: Among 1,017 biopsies, 34 hemorrhagic AEs were recorded. Severe hemorrhagic AEs, defined as those requiring secondary intervention, occurred in 1% (10 of 1,017) of cases, with a significantly higher incidence in the ≤90-day graft group than in the >90-day graft group (1.57% [8 of 509] vs 0.39% [2 of 508], P = .04). Mild hemorrhagic AEs, managed conservatively, were observed in 2.4% (24 of 1,017) of cases, with no significant difference between the ≤90-day group (1.77% [9 of 509]) and the >90-day group (2.95% [15 of 508], P = .24). No graft failures were reported during the study period. The median time from biopsy to surgical evacuation for severe AEs was 3.5 hours (interquartile range, 2.8-5.1 hours).Conclusions: Biopsies performed within 90 days after transplantation were associated with a significantly increased risk of severe hemorrhagic AEs requiring secondary intervention. These findings underscore the need for careful risk stratification and precautionary measures when performing transplant kidney biopsies in early grafts.","PeriodicalId":49962,"journal":{"name":"Journal of Vascular and Interventional Radiology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144976715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For same-day radioembolization, once operators determined the required number and activity of vials, daughter vials were dispensed from a mother vial in the hospital nuclear medicine facility and then delivered to the angiography room. Tumor responses and toxicity between same-day radioembolization and multiday radioembolization were compared using the chi-square test.Results: Among 80 patients who were scheduled to receive same-day radioembolization, 4 were excluded because of a high estimated lung dose, leading to the rejection of the radioembolization procedure. The remaining 76 patients (median tumor size, 8.3 cm) were treated with resin microspheres, using a median activity of 2.7 GBq. The median time interval from the initiation of planning angiography to the completion of radioembolization was 215 minutes. Among patients with hepatocellular carcinoma, the objective response rates by modified Response Evaluation Criteria in Solid Tumors were 87.7% (50/57) for same-day radioembolization and 89.2% (99/111) for multiday radioembolization (P = .776).

A multiple linear regression model assessed the association of anesthesia type and vasoconstrictor administration with intralymphatic contrast agent transit time, controlled for confounders.Results: A total of 147 lymphangiograms from 141 patients (median age, 64 years [interquartile range, 56-72 years]) were reviewed. Sedation (vs GA) was associated with 43% shorter log-transformed contrast agent transit time (βˆ = 1.43; 95% CI, 1.04-1.97; P = .029), reflecting a 13-minute faster median contrast agent transit time (absolute standardized difference, 0.44).

In addition to its association with increased contrast agent transit time, GA also added a median of 16 minutes (range, 11.0-22.3 minutes) of anesthesiology care time to cases.Conclusions: Sedation (vs GA), but not vasoconstrictor administration, was associated with shorter contrast agent transit time and anesthesiology care time.

Survival outcomes, computed tomography (CT) imaging findings, and histopathological features including hemosiderin deposition were evaluated. Chronic effects were assessed at 10 weeks through histopathology and hemosiderin deposition quantification. Human equivalent doses (HEDs) were calculated using body weight ratio conversion.Results: The LD50 was determined to be 30 μL in mice, corresponding to an HED of 94.7 mL for a 60-kg human. All mice receiving 50 μL died immediately, whereas the 30-μL group showed 50% survival. CT imaging revealed dose-dependent ethiodized oil accumulation predominantly in pulmonary vasculature, with regional heterogeneity in distribution patterns.
