[Portal venous flow as a prognostic factor in biliary atresia. A preliminary study].

Early prognosis factors determination is an important objective after Kasai's operation for biliary atresia repair. Serologic test, postoperative biliary flow, histologic studies and clinical manifestations provides adjunctive information. Hemodynamic patterns in biliary atresia where described in 80's before liver transplantation. This preliminary report evaluates portal flow velocity, hepatic arterial resistance and portal calibre in these patients. A prospective sonographic investigation was performed in ten children with biliary atresia. Hemodynamic findings and hepatobiliary function were compared in order to establish prognosis. All our patients with good prognosis had hepatopedal portal flow greater than 14 cm/sg, and arterial resistance between 0.68-0.78. Four patients with poor prognosis had hepatopedal flow lesser than 14 cm/sg or hepatopedal flow an resistance in hepatic artery was greater than 0.80.

A selective ventilation distribution circuit (S.V.D.C).

A circuit for selective ventilation distribution (S.V.D.C.) is described. The use of the circuit is illustrated with five cases in which it was used. S.V.D.C. allowed: 1) Measurement of individual lung tidal volumes and pressures during the respiratory cycle. 2) Adjustment of the tidal volumes of both lungs in the most appropriate way for the patient. 3) Application of different degrees of PEEP to each lung. The circuit is easily built and managed, the patient is connected to it by a double lumen endotracheal tube (Carlens tube); the circuit requires only one respirator.
