- Estudo comparativo entre o uso do antiagregante plaquetário e do anticoagulante oral na profilaxia de trombose em pacientes submetidos à operação cavopulmonar total com tubo extracardíaco: análise ecocardiográfica, angiotomográfica, cintilográfica, laboratorial e clínica Cristiane Felix Ximenes Pessotti Marcelo Biscegli Jatene Ieda Biscegli Jatene Patrícia Marques Oliveira Fabiana Moreira Passos Succi Valeria de Melo Moreira Rafael Willain Lopes Simone Rolim Fernandes Fontes Pedra Medicina aspirin warfarin thrombosis Fontan procedure prospective studies Objective: To compare the efficacy of aspirin and warfarin for prophylaxis of thrombosis in patients undergoing total cavopulmonary anastomosis. Evaluate whether coagulation factors (VII, VIII and protein C), clinical data, fenestration or hemodynamic factors, interfere with postoperative thrombosis. Methods: A prospective, randomized study of 30 patients, randomized into Group I (Warfarin) and Group II (AAS), underwent total cavopulmonary shunt with extracardiac conduit, between 2008 and 2011, with follow-up by clinical visits to evaluate side effects and adhesion. Performed transesophageal echocardiography in post operatory time, 3, 6,12 and 24 months; angiotomography at 6, 12 and 24 months to evaluate changes in the internal tube wall or thrombi and pulmonary scintigraphy to evaluate possible PTE. Results: Two deaths in group I; 33.3% of patients had thrombus (46.7% in Group II). The previous occurrence of thrombus and low levels of coagulation protein C were the only factors that influenced the time free of thrombus (P=0.035 and 0.047). Angiotomographic evaluation: 35.7% in group II presented material accumulation greater than 2 mm (P=0.082). Scintigraphy: two patients had PTE in group II. Five patients had difficulty to comply with the treatment, 4 in group I with INR ranging from 1 to 6.4. Conclusion: The previous occurrence of thrombus is a risk factor for thrombosis in the postoperative period. Patients using AAS tend to deposit material in the tube wall. The small sample size did not allow to conclude which is the most effective drug in the prevention of thrombosis in this population. 2014 artículo científico 0102-7638 https://www.redalyc.org/articulo.oa?id=398941895019 pt http://www.redalyc.org/revista.oa?id=3989 Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery application/pdf Sociedade Brasileira de Cirurgia Cardiovascular Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery (Brasil) Num.4 Vol.29
