Purpose: To report the feasibility and long-term clinical outcome of percutaneous aspiration thrombectomy for treating acute or subacute arterial thromboembolism in the infrainguinal arteries. Materials and Methods: Thirty limbs of 29 patients were enrolled in this retrospective study between January 2004 and March 2014. Nine limbs underwent overnight catheter-directed thrombolysis followed by percutaneous aspiration thrombectomy (PAT). Eighteen limbs underwent PAT with adjunctive selective intra-arterial thrombolysis in a single session. The remaining three limbs underwent PAT alone. Balloon angioplasty (n = 16) or stent placement (n = 3) was performed as required. In-hospital mortality and complications were estimated. The primary patency rate and the rate of freedom from reintervention were calculated using the Kaplan-Meier method. Results: Technical success was achieved in 28 limbs. Clinical success was achieved in 27 limbs. The mean ankle-brachial index increased from 0.17 ± 0.26 to 0.98 ± 0.19 after the procedure. Three in-hospital deaths and no major amputations were recorded. Distal embolization of crural arteries occurred as a minor complication in five limbs, but no major complications occurred. The primary patency rate and the rate of freedom from reintervention were 74.9% and 90.9% at 1 year, respectively, and 66.6% and 80.8% at 2 years, respectively. Conclusion: PAT is a rapid and effective method to remove a thrombus from occluded infrainguinal arteries.

Purpose – This study is regarding customer service environment in casino marketing under a study on the factors affecting casino tourist satisfaction based on casino tourists’ various needs. Research design and methodology – The study of casino tourism policy factors is proceeded by interviewing tourists of Macao casino. A total of 220 copies were distributed and 193 copies were collected, but 13 copies were not conceded due to insincere responses, and a total of 180 cases were analyzed for this study. Based on the analysis results, the casino tourism policy factors were derived through satisfaction level of casino tourist service as follows. Results – Firstly, the casino tourist satisfaction is a positive influence on casino visits, so efforts should be made to enhance tourist satisfaction when establishing cultural experience programs and casino marketing strategies. Casino culture for tourist should be matured to develop casino tour. In order to increase the satisfaction level of revisiting casino resorts, various cultural products such as clean environment should be developed to enhance the satisfaction level of casino visitors in the future. Secondly, a positive impact of cultural, experiential visits and psychological motivations affect to tourists’ psychological stability through cultural experiences as well as casino games. Thirdly, casino tourist satisfaction has been shown to provide a positive impact on behavior intention.

Objective: To determine the efficacy of retrievable metallic stent with fixation string for benign anastomotic stricture after upper gastrointestinal (UGI) surgery. Materials and Methods: From June 2009 to May 2015, a total of 56 retrievable metallic stents with fixation string were placed under fluoroscopy guidance in 42 patients who were diagnosed with benign anastomotic stricture after UGI surgery. Clinical success was defined as achieving normal regular diet (NRD). Results: The clinical success rate after the first stent placement was 57.1% (24/42). After repeated stent placement and/or balloon dilation, the clinical success rate was increased to 83.3% (35/42). Six (14.3%) patients required surgical revision to achieve NRD. One (2.4%) patient failed to achieve NRD. Stent migration occurred in 60.7% (34/56) of patients. Successful rate of removing the stent using fixation string and angiocatheter was 94.6% (53/56). Distal migration occurred in 12 stents. Of the 12 stents, 10 (83.3%) were successfully removed whereas 2 could not be removed. No complication occurred regarding distal migration. Conclusion: Using retrievable metallic stent with a fixation string is a feasible option for managing early benign anastomotic stricture after UGI surgery. It can reduce complications caused by distal migration of the stent.
