Extrinsic compression of the inferior vena cava by large abdominal masses may simulate occlusion on supine cavography. Seventeen children with large abdominal masses were evaluated by inferior venacavography. There was either occlusion or severe compression of the IVC on supine cavography in 13 patients; but the decubitus cavagram and subsequent surgery confirmed patency in 12 patients. In four patients only minor indentations or no abnormalities were present. Pseudo-obstruction of the IVC can be accurately differentiated from occlusion due to invasion by a lateral cavagram in the decubitus position.
巨大腹部肿块对下腔静脉的外在压迫在仰卧位腔静脉造影时可能模拟阻塞。对17例有巨大腹部肿块的儿童进行了下腔静脉造影评估。仰卧位腔静脉造影时，13例患者存在下腔静脉阻塞或严重受压；但侧卧腔静脉造影片及随后的手术证实12例患者血管通畅。4例患者仅存在轻微压痕或无异常。通过侧卧位腔静脉造影片可准确区分下腔静脉假性梗阻与肿瘤侵犯所致的阻塞。
