Abstract

Calcified thrombi in the prerenal (suprarenal) segment of the inferior vena have a characteristic radiographic appearance that permits accurate "plain film" diagnosis. Most have been fortuitously discovered in infants and young children. None of the affected individuals has had clinical evidence of venous obstruction. Vena caval obstruction is usually incomplete. Uncalcified clot caudal to the calcified thrombus caused complete obstruction of the inferior vena cava and renal veins in one of our patients, a healthy infant; since collateral flow was adequate surgery was not advised. We believe that aggressive diagnostic and therapeutic measures are unnecessary in the management of infants and children with calcified thrombi in the inferior vena cava.

摘要

下腔静脉肾前(肾上腺上)段的钙化血栓具有特征性的影像学表现,可进行准确的“平片”诊断。大多数是在婴幼儿中偶然发现的。所有受影响个体均无静脉阻塞的临床证据。腔静脉阻塞通常不完全。在我们的一名健康婴儿患者中,钙化血栓尾侧的未钙化血栓导致下腔静脉和肾静脉完全阻塞;由于侧支血流充足,未建议进行手术。我们认为,对于下腔静脉有钙化血栓的婴幼儿,无需采取积极的诊断和治疗措施。
