RESUMO
Background and Objectives: This study was aimed at determining our experience with occluder devices over last 5 years. The objective of this study is to compare the complication rates and efficacy of different devices used for the closure of PDA. Methods: A cross-sectional retrospective study in which a review of the records of all children who had PDA surgery in a paediatric cardiac center, Innova Childrens’ Heart Hospital, Hyderabad, India over a five year period (June 2007 and July 2011) was undertaken. The hospital records showed that from June 2007 to July 2011, a total of 456 children aged 9 months to 18 years had trans-catheter closure over the study period, of these, 159 underwent trans-catheter device closure of PDA. A team of experienced paediatric cardiologist performed all the procedures. Results: Out of the 159 cases, 134 (84.2%) were successful while 25 (15.7%) were complicated. Five (5) {20.0%} cases had temporary residual leak, 3 (12.0%) had failure of the procedure that required surgical intervention, 9 (36.0%) had protrusion of the device into the aorta without significant Doppler pressure gradient. There exist a relation between success, complication and device used for the procedure.The type of occluder device used for the procedure significantly affect the outcome (χ2 = 16.37; p = 0.02) Chinese occlude devise had the highest success rate. Twenty five (25.0) {15.7%} patients had complications in all. The commonest complication (protrusion of the device into the aorta) was seen in 3 (1.8%) cases with Chinese duct occluder, 3(1.8%) with Sear Heart R and 3 (1.8%) cases with ADOs. Non died from the procedure. Conclusion: The commonest complication is (protrusion of the device into the aorta) with Chinese occludes devise showing the highest success rate. The learning curve and accumulating experience play an indispensable role in choosing the proper device and its size.
RESUMO
Objective : To determine if there is a correlation between blood pressure and anthropometry in children of Igbo ethnicity.Subjects, Materials and Methods: One thousand, six hundred and thirty-four boys and 1669 girls were studied. Their ages ranged from 6 to 14 years. Their blood pressures, weights and heights were measured. The Quetelet's indices were determined and the correlation coefficients, r, found.Results:For boys, weight correlated (r=0.3205) more than height (r=o.2585) with systolic blood pressures. These values were nonetheless statistically significant. For their diastolic blood pressures, it was observed that all the variables showed weak correlation; weight (r=0.1785), height (r=0.1504), Quetelet's index (r=0.0828)The values for the girls showed moderate correlation of all the variables with their systolic blood pressure; weight (r=0.4249), height (r=0.3972), Quetelet's index (r=0.3915). Their diastolic blood pressures showed statistically. significant though weak correlation with the variables; height and Quetelet/'s index (r=0.1667) each, weight (r=0.1656).Conclusion: This study shows that in the Nigerian children examined, blood pressure is affected by anthropometry, and of all the anthropometric values, weight affected blood pressures most. Anthropometry influenced systolic blood pressure more than diastolic blood pressure
