| 1 | A study of pulmonary embolism after abdominal surgery in patients undergoing prophylaxis显示文摘AIM:To determine risk factors for pulmonary embolism and estimate effects and benefits of prophylaxis.METHODS:We included 78 patients who died subsequently to a pulmonary embolism after major abdomi nal surgery from 1985 to 2003.A first,retrospective analysis involved 41 patients who underwent elective surgery between 1985 and 1990 without receiving any prophylaxis.In the prospectively evaluated subgroup,37 patients undergoing major surgery between 1991 and 2003 were enrolled:all of them had received a prophylaxis consisting in low-molecular weight heparin,given subcutaneously at a dose of 2850 IU AXa/0.3 mL(body weight < 50 kg) or 5700 IU AXa/0.6 mL(body weight ≥ 50 kg).RESULTS:A higher incidence of thromboembolism(43.9% and 46.34% in the two groups,respectively) was found in older patients(> 60 years).The incidence of pulmonary embolism after major abdominal surgery in patients who had received the prophylaxis was signifi cantly lower compared to the subjects with the same condition who had not received any prophylaxis(P < 0.001,OR = 2.825;95% CI,1.811-4.408).Furthermore,the incidence of pulmonary embolism after colorectal cancer surgery was signifi cantly higher compared to incidence of pulmonary embolism after other abdominal surgical procedures.Finally,the incidence of pulmonary embolism after colorectal cancer surgery among the patients who had received the prophylaxis(11/4316,0.26%) was significantly lower compared to subjects undergoing a surgical procedure for the same indication but without prophylaxis(10/1562,0.64%)(P < 0.05,OR = 2.522;95% CI,1.069-5.949).CONCLUSION:Prophylaxis with low molecular weight heparin is highly recommended during the preoperative period in patients with diagnosis of colorectal cancer due to high risk of pulmonary embolism after elective surgery. | Mirko D Kerkez Dorde M ulafi Dragana D Mija Vitomir I Rankovi Nebja S Leki Dejan Z Stefanovi | 2009 | World Journal of Gastroenterology2009，15，3： | 14 |
| 2 | Color Doppler sonography and angioscintigraphy in hepatic Hodgkin's lymphoma显示文摘AIM:To estimate the characteristics of Color Doppler findings and the results of hepatic radionuclide angiography (HRA) in secondary Hodgkin's hepatic lymphoma.METHODS:The research included patients with a diagnosis of Hodgkin's lymphoma with metastatic focal lesions in the liver and controls.Morphologic characteristics of focal liver lesions and hemodynamic parameters were examined by pulsed and Color Doppler in the portal,hepatic and splenic veins were examined.Hepatic perfusion index (HPI) estimated by HRA was calculated.RESULTS:In the majority of patients,hepatomegaly was observed.Lesions were mostly hypoechoic and mixed,solitary or multiple.Some of the patients presented with dilated splenic veins and hepatofugal blood flow.A pulse wave was registered in the centre and at the margins of lymphoma.The average velocity of the pulse wave was higher at the margins (P>0.05).A continuous venous wave was found only at the margins of lymphoma.There was no linear correlation between lymphoma size and velocity of pulse and continuous wave (r=390,P<0.01).HPI was significantly lower in patients with lymphomas than in controls (P<0.05),pointing out increased arterial perfusion in comparison to portal perfusion.CONCLUSION:Color Doppler ultrasonography is a sensitive method for the detection of neovascularization in Hodgkin's hepatic lymphoma and estimation of its intensity.Hepatic radionuclide angiography can additionally help in the assesment of vascularisation of liver lesions. | Mirjana V Stojkovi Vera M Artiko Irena B Radoman Slavko J Knezevi Snezana M Luki Mirko D Kerkez Nebojsa S Leki Andrija A Anti Marinko M Zuvela Vitomir I Rankovi Milorad N Petrovi Dragana P obi Vladimir B Obradovi | 2009 | World Journal of Gastroenterology2009，15，26： | 2 |
