During the bidirectional Glenn shunt procedure in small infants, the standard right-angle venous cannula is frequently placed in the innominate vein for establishing the temporary veno-atrial bypass without cardiopulmonary bypass, but it should be small enough to allow flow to pass around it from the internal jugular vein opposite to the side the cannula is directed. Small cannula may induce the inadequacy of venous drainage. We developed a modified right-angle venous cannula and placed it within the innominate vein for sufficient venous drainage. The standard right-angle venous cannula was simply modified by an oval open on the top of the external curvature. Our initial application demonstrated that this modified venous cannula provides better venous drainage during the bidirectional Glenn shunt procedure without cardiopulmonary bypass in small infants.
在小婴儿进行双向格林分流手术时，标准直角静脉插管常置于无名静脉以建立无体外循环的临时腔静脉 - 心房旁路，但它应足够小，以便血流能从与插管指向相反一侧的颈内静脉绕过它通过。小插管可能导致静脉引流不足。我们研发了一种改良的直角静脉插管，并将其置于无名静脉内以实现充分的静脉引流。标准直角静脉插管仅通过在外部弯曲顶部开一个椭圆形开口进行改良。我们的初步应用表明，这种改良的静脉插管在小婴儿无体外循环的双向格林分流手术中能提供更好的静脉引流。
