| Summary: | The mechanism for development of schistosomal myelitis has not yet been completely understood. Few publications have tried to establish a link between the general clinical presentation of the illness and its neurological manifestations. Objective: To evaluated the portal blood flow in patients with schistosomal myelitis and controls. Method: Forty-three individuals were evaluated using portal Doppler ultrasound. Group I consisted of 13 patients with the spinal form of schistosomiasis. Group II included 10 patients with intestinal and hepatointestinal forms of schistosomiasis, but no neurological symptoms; while group III involved 20 healthy controls. Results: Portal venous speed and portal venous flow were significantly elevated in group I (p<0.001) compared with the others. Conclusion: Doppler ultrasound demonstrated a situation of high flow within the portal venous system of patients with schistosomal myelitis.<br>A fisiopatogênese da mielopatia esquistossomótica não é completamente entendida, sendo escassas as publicações que tentam inferir a relação entre a forma clínica da esquistossomose e suas manifestações neurológicas. Objetivo: Avaliar o fluxo sanguíneo do sistema porta em pacientes com mielite esquistossomótica, contribuindo no entendimento dos mecanismos que favorecem a chegada dos parasitas e/ou seus derivados ao sistema nervoso. Método: Foram avaliados 43 indivíduos pela Dopplerfluxometria portal. O grupo I constou de 13 pacientes com esquistossomose medular, sendo o grupo II composto por 10 portadores de formas intestinal e hepatointestinal (sem doença neurológica), e o grupo III, por 20 controles sadios. Resultados: A velocidade venosa portal e o fluxo venoso portal foram significativamente elevados (p-valor<0,001) no grupo I. Conclusão: A Dopplerfluxometria demonstrou a presença de estados hiperdinâmicos do leito vascular porta em pacientes com mielite pelo Schistosoma mansoni. |
