Medida da pressão e tensão da parede de varizes esofagianas em pacientes com esquistossomose mansônica hepato-esplênica com e sem antecedente de hemorragia digestiva / -

Fabio Kassab 14 April 2005 (has links)
O objetivo desse estudo foi comparar a pressão das varizes (PV), a tensão da parede (TP) e parâmetros endoscópicos, ultra-sonográficos e de Doppler em esquistossomóticos com (grupo I, n=7) e sem (grupo II, n=12) antecedente de sangramento. A PV and a TP no grupo I foi 14,7±3,0 mm Hg e 526,1±234,4, em contraste com 11,0±2,0 and 340,8±103,8 no grupo II (p=0,0053). PV acima de 12 mmHg foi observada em 71% dos casos com sangramento prévio e em 8% daqueles que nunca sangraram (0,0095). A PV correlacionou-se significantemente com a TP (p=0,0022). Nenhum parâmetro endoscópico, ultra-sonográfico ou de Doppler foi capaz de diferenciar os grupos I e II / This study was undertaken to compare variceal pressures (VP), wall tensions (WT), and endoscopic, ultrasound and Doppler parameters in schistosomiasis patients with (group I, n=7) and without (group II, n=12) previous bleeding. The VP and the WT in group I were 14.7±3.0 mm Hg and 526.1±234.4 respectively, in contrast to 11.0±2.0 and 340.8±103.8 in the group II (p=0,0053). VP over 12 mmHg was found in 71% of the patients with previous hemorrhage, compared with 8% of patients who had never bled (0,0095). VP significantly correlated with WT (p=0,0022). No endoscopic, ultrasound or Doppler parameters were shown to be different in patients with and without previous bleeding
