Catheterization of the aorta via the umbilical artery provides a convenient route for monitoring arterial blood pressure, for obtaining blood specimens for measurement of blood gas tensions and chemistries, and for the infusion of fluids and pharmacologic preparations in sick newborn infants. Use of this technique may be accompanied by a number of complications of which thrombotic phenomena are the most common. Twenty-three of 98 (24%) newborn infants undergoing umbilical artery catheterization were found to have thrombotic complication determined by aortography. No correlation was present between the duration of time that the umbilical artery catheters were in place and the occurrence of thrombotic complications. From paired aortographic or aortographic and autopsy studies in 24 patients, it was concluded that if a thrombotic complication did not occur early, none was likely to occur subsequently. One patient was considered to have died as a direct result of a thrombotic complication. Aortography is a safe, simple, and reliable technique for the early detection of thrombotic complications of umbilical artery catheters. Umbilical artery catheterization is not without risk and careful selection of patients for this procedure is indicated.
经脐动脉进行主动脉插管为监测动脉血压、获取血标本以测量血气张力和化学成分以及为患病新生儿输注液体和药物制剂提供了一条便捷途径。使用该技术可能会伴随多种并发症，其中血栓形成现象最为常见。在98例接受脐动脉插管的新生儿中，经主动脉造影发现23例（24%）有血栓形成并发症。脐动脉导管留置时间与血栓形成并发症的发生之间不存在相关性。通过对24例患者进行的成对主动脉造影或主动脉造影与尸检研究得出结论，如果早期未发生血栓形成并发症，则随后发生的可能性不大。1例患者被认为直接死于血栓形成并发症。主动脉造影是早期检测脐动脉导管血栓形成并发症的一种安全、简单且可靠的技术。脐动脉插管并非没有风险，因此需要谨慎选择适合该操作的患者。
