PURPOSE: To report technical success, outcomes, and patency of iliocaval stent reconstruction for inferior vena cava (IVC) filter-bearing iliocaval thrombosis. MATERIALS AND METHODS: A total of 120 patients with 123 IVC filters and symptomatic iliocaval thrombosis underwent stent reconstruction. Mean patient age was 55 years (range, 19-88 y). Filters included 70 (57%) retrievable and 53 (43%) permanent filters. Symptoms included lower extremity swelling or pain (n = 93), ulcers (n = 8), phlegmasia (n = 7), back pain (n = 5), shortness of breath (n = 4), worsening renal function (n = 2), and stenosis identified during translumbar catheter placement (n = 1)...

PURPOSE: To determine if outpatient medications taken at the time of liver tumor embolization or ablation affect survival. MATERIALS AND METHODS: A retrospective review was done of 2,032 liver tumor embolization, radioembolization, and ablation procedures performed in 1,092 patients from June 2009 to April 2016. Pathology, hepatocellular carcinoma (HCC) stage (American Joint Committee on Cancer), neuroendocrine tumor (NET) grade, initial locoregional therapy, overall survival after initial locoregional therapy, Child-Pugh score, Eastern Cooperative Oncology Group performance status, Charlson Comorbidity Index, and outpatient medications taken at the time of locoregional therapy were analyzed for each patient...

PURPOSE: It is hypothesized that intraarterial administration of verapamil is a safe and effective way to reverse the flow in intraprostatic anastomoses to extraprostatic arteries without compromising treatment outcomes in prostatic artery embolization (PAE) for benign prostatic hypertrophy (BPH). MATERIALS AND METHODS: A prospective study of 62 prostate sides in 31 consecutive patients (median age, 66 y; range, 60-71 y) with symptomatic BPH was undertaken. Median prostate volume was 72...

PURPOSE: To compare physicochemical properties of emulsions of ethiodized oil (Lipiodol; Guerbet, Villepinte, France) and epirubicin prepared using different techniques for conventional transarterial chemoembolization. MATERIALS AND METHODS: Lipiodol was mixed with epirubicin solution (8.33 mg/mL) by using a 3-way stopcock. The following technical parameters were compared: ratio of epirubicin solution to Lipiodol (1:2 vs 1:1), number of pumping exchanges through the stopcock (20 exchanges vs 10 exchanges), pumping speed (1 s/push vs 2 s/push), and first push syringe (epirubicin solution vs Lipiodol)...

PURPOSE: To test the hypotheses that (i) heavier rats demonstrate improved survival with diminished fibrosis in a diethylnitrosamine (DEN)-induced model of hepatocellular carcinoma (HCC) and (ii) transarterial embolization via femoral artery access decreases procedure times versus carotid access. MATERIALS AND METHODS: One hundred thirty-eight male Wistar rats ingested 0.01% DEN in water ad libitum for 12 weeks. T2-weighted magnetic resonance imaging was used for tumor surveillance...

PURPOSE: To study the factors that might impact infarction of individual uterine leiomyomas and total tumor burden after uterine artery embolization (UAE). MATERIALS AND METHODS: This retrospective study included 91 patients (mean age, 44 y [range, 34-54 y]) who underwent UAE with tris-acryl gelatin microspheres (TAGMs) or nonspherical polyvinyl alcohol (PVA) particles. Twenty-one patients were treated with PVA (23%) and 70 were treated with TAGMs (77%). A total of 356 uterine leiomyomas were assessed, with a median uterine volume of 533 cm(3) (range, 321-848 cm(3))...

PURPOSE: To investigate the relationship between recanalization rate of occluded veins after deep venous thrombosis (DVT) and development of postthrombotic syndrome (PTS). MATERIALS AND METHODS: Patients treated for DVT of the lower limbs were evaluated 12-36 months after acute DVT. Of 100 patients, 34 developed PTS, defined as Villalta score of ≥ 5. Symptoms and signs of PTS were assessed, and ultrasound examination of the veins was performed, checking for residual thrombus and presence of reflux...

PURPOSE: To determine frequency of and assess risk factors for hepatic artery (HA) injury during percutaneous transhepatic biliary drainage (PTBD) and to discuss the technique and report the clinical outcome of embolization for HA injury. MATERIALS AND METHODS: Over a 14-year period (2002-2016), 1,304 PTBD procedures in 920 patients were recorded. The incidence of HA injury was determined, and possible associated risk factors were analyzed. When injury occurred, HA embolization was performed at the site as close to the bleeding point as possible...

PURPOSE: To evaluate potential biologic and thermal mechanisms of the observed differences in thrombosis rates between hepatic vessels during microwave (MW) ablation procedures. MATERIALS AND METHODS: MW ablation antennae were placed in single liver lobes of 2 in vivo porcine liver models (n = 3 in each animal; N = 6 total) in the proximity of a large (> 5 mm) portal vein (PV) and hepatic veins (HVs). Each ablation was performed with 100 W for 5 minutes. Conventional ultrasound imaging and intravascular temperature probes were used to evaluate vessel patency and temperature changes during the ablation procedure...

PURPOSE: To retrospectively review and report the efficacy and safety of percutaneous image-guided ablation (cryoablation or radiofrequency ablation) in the treatment of oligometastatic prostate cancer. MATERIALS AND METHODS: An institutional registry was retrospectively reviewed and revealed 16 patients with oligometastatic prostate cancer (median age, 67 y; range, 50-86 y) who underwent percutaneous image-guided ablation to treat 18 metastatic sites. A subgroup of 7 patients with 8 metastases were androgen-deprivation therapy (ADT)-naïve and underwent ablation to delay initiation of ADT...

PURPOSE: To investigate treatment outcome, prognostic factors for overall survival, and appropriate candidates for transarterial chemoembolization among patients with hepatocellular carcinoma (HCC) and extrahepatic spread (EHS). MATERIALS AND METHODS: From January 2010 to June 2014, 111 consecutive patients with HCC and EHS treated by transarterial chemoembolization alone were evaluated. Factors associated with overall survival were evaluated using Cox regression analysis, and a scoring equation was established to subgroup patients with EHS...

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. HCC develops through a multistep process that involves the local tumor microenvironment, intracellular signaling pathways, and altered metabolic system that allows the cancer proliferation. Understanding the mechanisms of tumor development and progression is critical to developing improved therapies aimed at better survival. This article reviews the molecular mechanisms of HCC development and highlights the potential therapeutic targets for treatments...
