RESUMO
The aim of this study was to evaluate the safety and clinical effectiveness of endovascular stent repair of celiac arterial aneurysm (CAA).From January 2015 to December 2018, 11 patients (7 males, 4 females with a mean age of 52.2â±â7.9 years) underwent endovascular stent repair of CAA in our center. A covered stent was used to occlude the CAA neck. Follow-up was performed 2 weeks and 1, 3, 6, and 12 months following surgery and yearly thereafter. Rates of technical success, treatment-related complications, and long-term outcome were analyzed.Each patient was placed with 1 stent for repair of CAA. Stent was placed in the celiac and common hepatic arteries for 10 patients and was placed in the celiac artery for 1 patient. The duration of the procedure ranged from 50 to 75âminutes (mean 63.2â±â7.2âminutes). The rate of technical success of the endovascular stent repair was 100%. No patient experienced CAA rupture or instant endoleak during or after stent insertion. Abdominal pain was relieved progressively after stent insertion. All patients were followed-up for 6 to 48 months (mean 22.4â±â10.8 months). All patients were alive during the follow-up. No endoleaks were experienced during follow-up with 100% stent patency rate. No patient suffered splenic, hepatic, or bowel infarction during follow-up.Endovascular stent repair is a safe, simple, and effective treatment for patients with CAA.

To reduce the negative effect of algae on conventional water treatment, a full-scale research of removing algae from algae-laden raw water by stocking filter-feeding silver carp was processed. After the pretreatment in a presedimentation tank with silver carp, the concentration of phytoplankton, the biomass of cyanobacteria and Microsystis flos-aquae in algae-laden raw water with Microsystis flos-aquae its dominant species decreased 61.8%, 76.1% and 78.2% respectively. This effective decrease of algae load on conventional process created favorable conditions for water treatment. Analysis indicates that food habit of silver carp and algae size are two causes of different removal efficiency between cyanobacteria and green algae. The results show that biomanipulation of silver carp is applicable for treating algae-laden raw water in which colonial cyanobacteria is dominant.
