To evaluate the efficacy and safety of cyanoacrylate glue embolization in the treatment of severe arterioportal shunt (APS) presenting with hepatofugal portal venous flow in hepatocellular carcinoma (HCC) patients. Between July 2000 and January 2010, 27 HCC patients with severe APS presenting with hepatofugal portal venous flow underwent transarterial angiography and treatment. Among them, four patients were excluded from the study. Twelve patients underwent transarterial chemoperfusion and embolization of APS with cyanoacrylate glue between January 2006 and January 2010 (Emb group), and the other 11 patients undergoing only transarterial chemoperfusion without embolization of APS between July 2000 and December 2005 served as a control group (non-Emb group). The change of APS, survival rates, and procedure related complications were analyzed. In the Emb group, APS was improved in all of the 12 patients after initial glue embolization; long-term APS improvement with hepatopetal portal flow was achieved in 80 % (8 of 10) patients who underwent follow-up angiography. Survival rates in the Emb group were 67 % at 6 months, 33 % at 1 year, and 8 % at 2 years, whereas those in the non-Emb group were 0 % at 6 months (P

To evaluate the clinical effectiveness of a newly designed stent for the treatment of malignant distal duodenal stenosis. From March 2011 to May 2013, six patients with malignant duodenal stenosis underwent fluoroscopically guided placement of the new duodenal stent consisting of braided, nested stent wires, and a delivery system with a metallic mesh inner layer. Primary diseases were pancreatic cancer in three patients, gastric cancer in two patients, and endometrial stromal sarcoma in one patient. Duodenal obstructions were located in the horizontal part in two patients, the ascending part in two patients, and the duodenojejunal flexure in two patients. Technical success, defined as the successful stent deployment, clinical symptoms before and after the procedure, and complications were evaluated. Technical success was achieved in all patients. No major complications were observed. Before treatment, two patients could not take any food and the gastric outlet obstruction scoring system (GOOSS) score was 0; the other four patients could take only liquids orally (GOOSS score = 1). After treatment, five patients could take soft food (GOOSS score = 2) and one patient could take a full diet (GOOSS score = 3). The mean duration of primary stent patency was 115.7 days. The newly designed stent is associated with a high degree of technical success and good clinical outcome and may be clinically effective in the management of malignant distal duodenal obstruction.

This study was designed to evaluate the efficacy and safety of percutaneous mechanical thrombectomy (PMT) for acute massive pulmonary embolism (PE). Fourteen patients (8 men, 6 women) with a mean age of 55.4 (range, 38–71) years with acute massive PE were initially diagnosed by computed tomography (CT) and confirmed by pulmonary angiography. All patients presented with acute PE symptoms and hemodynamic compromise. Each patient was treated with Straub Rotarex thrombectomy device and five patients received additional thrombolysis. Technique success and clinical improvement were achieved in all patients without major complications. The mean pulmonary artery pressure (PAP) decreased from 37.6 ± 6.6 to 29 ± 6.4 mmHg (P
