PURPOSE: To evaluate the effects of endovascular denervation (EDN) on abdominal cancer pain relief. MATERIALS AND METHODS: From April 2017 to February 2018, 7 cancer patients (2 males and 5 females) were enrolled in this study. The diagnoses of the patients included 3 pancreatic cancer, 2 cervical carcinoma, 1 cholangiocarcinoma, and 1 esophageal cancer with retroperitoneum lymph nodes invasion. Denervation was carried out at the abdominal aorta close to the origin of celiac artery and superior mesenteric artery with the use of a multielectrode radiofrequency ablation catheter with settings of time 120 seconds and temperature 60°C...

Between September 2008 and August 2017, 36 patients (mean age 56 y; range, 30-89 y) underwent transvenous biopsy of suspected tumor thrombus or perivascular tumor. Intravascular biopsy was pursued because of inaccessible percutaneous access in 9 patients (25%) and as part of a planned revascularization procedure in 27 patients (75%). Histopathologic results showed malignancy in 26 patients (72%) and benign etiologies in 10 patients (28%). No patients required repeat biopsy. There were no complications related to the biopsy procedure...

PURPOSE: To identify whether symptom relief and stent patency vary with use of long-term anticoagulation after stent placement for benign superior vena cava (SVC) syndrome. MATERIALS AND METHODS: Patients with benign SVC syndrome treated with stent placement between January 1999 and July 2017 were retrospectively identified (n = 58). Average age was 49 years (range, 24-80 y); 34 (58%) were women, and 24 (42%) were men. Average follow-up was 2.4 years (range, 0...

PURPOSE: To evaluate outcome of endovascular elective repair and repair of ruptured isolated iliac artery aneurysms (IIAAs) as a primary treatment strategy. MATERIALS AND METHODS: All patients with an IIAA undergoing endovascular treatment were included. Aneurysms were classified according to an anatomic classification and treated with coiling of the internal iliac artery, stent graft placement in the common to external iliac artery, or placement of a bifurcated aortoiliac stent graft...

PURPOSE: To demonstrate the feasibility of detecting patency, stenosis, or occlusion of transjugular intrahepatic portosystemic shunt (TIPS) with four-dimensional (4D) flow MR imaging. MATERIALS AND METHODS: Sequential adult patients with TIPS were eligible for enrollment. Volumetric phase-contrast sequence was used to image TIPS. Particle tracing cine images were used for qualitative assessment of stenosis. TIPS was segmented to generate quantitative data sets of peak velocity...

PURPOSE: To evaluate the value of α-fetoprotein (AFP) classification criteria in predicting tumor response and patient survival and to discuss the agreement between AFP criteria and modified Response Evaluation Criteria In Solid Tumors (mRECIST). MATERIALS AND METHODS: Between January 2011 and December 2014, 147 patients with unresectable hepatocellular carcinoma (HCC) with baseline AFP levels ≥ 400 ng/mL who underwent transarterial chemoembolization as initial treatment were retrospectively enrolled for AFP/imaging correlation analysis...

PURPOSE: To compare relative cost-effectiveness of serial large-volume paracentesis (LVP) and transjugular intrahepatic portosystemic shunt (TIPS) creation for treatment of refractory ascites. MATERIALS AND METHODS: A decisional Markov model was developed to estimate payer cost and quality-adjusted life-ears (QALYs) associated with LVP and TIPS treatment strategies for cirrhotic patients with refractory ascites. Survival estimates were derived from an individual patient-level meta-analysis of prospective randomized clinical trials...

Three patients with a medical history of breast carcinoma and metastatic carcinomatous liver disease associated with severe portal hypertension and refractory ascites are presented. Transjugular intrahepatic portosystemic shunt creation was considered as a palliative treatment option and a valuable alternative to regular paracenteses in these patients. In 2 of the 3 patients, the refractory ascites was controlled for several months without need for paracentesis, and subsequently transjugular intrahepatic portosystemic shunt may provide valuable palliation and ascites control in patients with refractory ascites due to breast cancer-induced pseudocirrhosis...

PURPOSE: To assess the role of epithelial cell adhesion molecule (EpCAM)-positive circulating tumor cell (CTC) count in predicting survival outcomes of transcatheter arterial chemoembolization in patients with unresectable hepatocellular carcinoma (HCC). MATERIALS AND METHODS: EpCAM-positive CTC counts were prospectively determined via CellSearch in peripheral blood of 97 patients with unresectable HCC treated with chemoembolization. The impact of each CTC cutoff point on overall survival (OS) was evaluated by univariate Cox regression analysis...

PURPOSE: The primary end point of this trial was to determine the feasibility and safety of transarterial chemoembolization with the use of 75-150-μm drug-eluting embolics loaded with irinotecan (DEE-IRI) for the treatment of metastatic colorectal cancer (CRC) refractory to systemic chemotherapy. MATERIALS AND METHODS: Fourteen patients (mean age 57.9 years) with liver-dominant metastatic disease (14.3% unilobar, 85.7% bilobar), who had failed at least 1 line of chemotherapy, were enrolled and received up to 4 (mean 2...

PURPOSE: To investigate the differences in immune responses between cryoablation and irreversible electroporation (IRE) in a preclinical mouse model. MATERIAL AND METHODS: A mouse pancreatic cancer cell line (PANC-2) was implanted in the bilateral flanks of mice, and tumor-bearing mice were divided into 6 groups. One of the tumors was ablated either with contact cryoablation using an argon-cooled cryoablation probe for 1 minute at 5% power or by IRE for a total of 64 100-μs-duration, 1250-V/cm2 pulses with 100-ms spacing...

PURPOSE: To determine success and complication rates of percutaneous transjejunal biliary access (PTJBA) in patients with bilioenteric anastomoses. MATERIALS AND METHODS: In a single-center, retrospective study, 169 PTJBA procedures were performed over a 13.8-y period in 60 subjects (47 male; mean age, 54.5 y). Indications for biliary interventions were cholangitis (137 cases, 45 subjects) or hyperbilirubinemia (32 cases, 18 subjects). All patients had antecolic bilioenteric anastomoses without surgical fixation to the peritoneum (liver transplantation with hepaticojejunostomy, n = 37; hepatectomy with hepaticojejunostomy, n = 8; hepaticojejunostomy only, n = 12; pancreaticoduodenectomy, n = 3)...

PURPOSE: To measure the decay activity loss and delivery system residual activity loss of yttrium-90 (Y90 ) radioembolization treatments across resin and glass microsphere activities. MATERIALS AND METHODS: For Y90 administrations between December 2009 and June 2017 at the study institution, the prescribed activity, prepared activity, and delivered activity were recorded. Six hundred sixty-two administrations were reviewed-345 glass (0.21-8.52 GBq) and 317 resin (0...

PURPOSE: To explore optimal diagnostic criteria for localizing insulinomas with the selective arterial calcium injection (SACI) test using decision tree analysis. MATERIALS AND METHODS: A retrospective study included 86 vessels of 18 patients (5 men, 13 women; mean age 67 y; range, 49-73 y) with insulinomas who underwent SACI test between June 2007 and May 2016. Of 27 insulinomas, 7 were found in the head, 13 in the body, and 7 in the tail of the pancreas. Two patients had multiple tumors...

PURPOSE: To evaluate the safety and efficacy of prostatic artery embolization (PAE) using the combination of 50-μm and 100-μm polyvinyl alcohol (PVA) particles versus 100-μm PVA particles alone in the treatment of patients with symptomatic benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Over a 5-year period, 120 patients treated with PAE for lower urinary tract symptoms (LUTS) secondary to BPH were randomized to undergo embolization with 50-μm plus 100-μm PVA particles (group A) or 100-μm PVA particles alone (group B)...

PURPOSE: To report long-term results of iliofemoral stent placement after transcatheter aortic valve replacement (TAVR). MATERIALS AND METHODS: TAVR access-related complications treated with iliofemoral stent placement were recorded in 56 patients (mean age, 81 years; range; 53-93 years; 48% male) of 648 patients who underwent TAVR at a single center. Fifty-six patients treated with stent placement (40 patients with stent grafts and 16 patients with bare metal stents) underwent clinical and ultrasonographic follow-up after a mean of 676 days (range, 60-1840 days)...
