Objective To study the value of reverse CT scan in eliminating the respiratory motion artifacts in the thoracic CT of the patients with chronic obstructive pulmonary diseases(COPD).Methods Fourty patients with COPD were randomly selected and underwent chest CT examinations with the technique of GR-Helical including directive and reverse CT scans.The images were blindly evaluated by three experienced doctors.Results In 40 cases,the respiratory motion artifacts were present in 17 cases,among them,70.59%(12/17) artifacts was in lower lung field,and 64.7%(11/17) artifacts occurred in the people over 60 years of age.The rate of artifact was 35% at directive scan,while it was reduced to 7.5% at reverse scan,the image quality was improved at 27.5%.There was statistical significance in eliminating respiratory motion artifacts between two scanning method (P＜0.05).Conclusion Reverse CT scanning can effectively eliminating or reducing the respiratory motion artifacts in lower lung field,it is the best choice of scanning mode in elderly patients with COPD.

Objective To compare the clinical efficacy of two different injection ways in treating lower extremity varicose veins with foam sclerotherapy of lauromacrogol. Methods During the period from Dec. 2010 to Dec. 2012 a total of 80 patients with clinically-proved lower extremity varicosis were admitted to authors’ hospital. The patients were randomly and equally divided into two groups:anterograde group (n=40) and retrograde group (n=40). For patients of anterograde group, under fluoroscopy guidance the needle was directly punctured into the distal end of the varicose vein with subsequent injection of 1%lauromacrogol foam sclerosing agent, while for patients of retrograde group the opposite femoral vein was punctured by using Seldinger technique, then a catheter was inserted into the proximal part of the great saphenous vein of the diseased side, and 1%lauromacrogol foam sclerosing agent was injected into the varicose vein. The operation time, recovery time, the dosage of the sclerosing agent used, the incidence of complications and the use of additional treatment were recorded, and the results were statistically analyzed. All the patients were followed up for 3 - 6 months. Results No significant difference in the overall effective rate existed between the two groups at 3-6 months after the treatment (P>0.05). The preoperative and postoperative CEAP scores of the anterograde group were 3.70 ± 0.63 and 0.88 ± 1.18 respectively, while the preoperative and postoperative CEAP scores of the retrograde group were 3.73 ± 0.59 and 0.88 ± 1.27 respectively. The difference in CEAP score between preoperative values and postoperative ones was statistically significant in both anterograde group and retrograde group (P < 0.05). Besides, the differences in the operation time, recovery time, the dosage of the sclerosing agent used, the incidence of complications and the use of additional treatment between the two groups were also statistically significant. Conclusion In treating lower extremity varicose veins with foam sclerotherapy of lauromacrogol, the overall effectiveness of anterograde injection and retrograde injection is quite the same. As each injection way has its own advantages and disadvantages, the therapeutic scheme should be individualized for each patient.
