MATERIALS AND METHODS: A total of 131 patients who underwent RE for liver metastases from CRC, treated at 2 academic centers, were reviewed. Twenty-one baseline pretreatment clinical factors were analyzed in relation to OS by the Kaplan-Meier method along with log-rank tests and univariate and multivariate Cox regression analyses...

PURPOSE: To compare the drug effect in treated vessels and downstream effects in distal skeletal muscle of drug-coated balloons (DCBs) and drug-eluting stents (DESs) in a healthy preclinical swine model. MATERIALS AND METHODS: Four groups of treated iliofemoral arteries (percutaneous transluminal angioplasty [PTA]+DES, DCB+DES, DCB+bare metal stent [BMS], and DCB alone) of 12 healthy swine were assessed, with euthanasia at 30 days. Biological drug effect was evaluated using smooth muscle cell (SMC) loss score according to both depth and circumference as well a neointimal fibrin and medial proteoglycan scores which were compared between the 4 groups...

PURPOSE: To quantify the effect of transarterial embolization on microwave (MW) ablations in an in vivo porcine liver model. MATERIALS AND METHODS: Hepatic arteriography and cone-beam computed tomography (CT) scans were performed in 6 female domestic swine. Two lobes were embolized to an endpoint of substasis with 100-300-μm microspheres. MW ablations (65 W, 5 min) were created in embolized (n = 15) and nonembolized (n = 12) liver by using a 2.45-GHz system and single antenna...

PURPOSE: To compare differences in patient radiation exposure (PRE) during transarterial yttrium-90 (90 Y) radioembolization (TARE) between transradial access (TRA) and transfemoral access (TFA). MATERIALS AND METHODS: A total of 810 consecutive first-time TARE procedures in patients from 2013 to 2017 were retrospectively reviewed. A propensity score-matching (PSM) analysis matched TRA and TFA groups on the basis of patient age, sex, weight, height, cancer type, 90 Y microsphere type, and number of previous procedures from the same and opposite approaches...

PURPOSE: To evaluate cone-beam parenchymal blood volume (PBV) before and after embolization as a predictor of radiographic response to transarterial chemoembolization in unresectable hepatocellular carcinoma (HCC). MATERIALS AND METHODS: A phase IIa prospective clinical trial was conducted in patients with HCCs > 1.5 cm undergoing chemoembolization; 52 tumors in 40 patients with Barcelona Clinic Liver Criteria stage B disease met inclusion criteria. Pre- and postembolization PBV analysis was performed with a semiquantitative best-fit methodology for index tumors, with a predefined primary endpoint of radiographic response at 3 months...
