Factors influencing the rate of post-catheterization venous thrombosis were studied in 180 infants below one year of age. The initial cardiac catheterization was performed either with cutdown technique or percutaneously. At repeat catheterization on the ipsilateral side presence or absence of thrombosis was noted. The overall thrombosis frequency was higher than previously reported, 15.6 per cent. The rate increased with decreasing weight. An increased rate of thrombosis was also found with indwelling femoral vein catheter left in place for more than 24 hours, and infection. In 6 cases, thrombosis involved only the catheterized side and would have been missed by recatheterization from the contralateral side. It was noteworthy that 9 of the thromboses spared the catheterized vessel and engaged only the vena cava. Among factors not influencing thrombosis rate were age, type of cardiac malformation, cyanosis, early operation, catheterization time or balloon septostomy. Percutaneous or cutdown technique did not influence thrombosis rate.
对180名一岁以下婴儿进行了影响导尿后静脉血栓形成率的因素研究。最初的心脏导管插入术采用切开技术或经皮进行。在同侧重复导管插入术时，记录有无血栓形成。总体血栓形成频率高于先前报道，为15.6%。血栓形成率随体重减轻而增加。留置股静脉导管超过24小时以及感染也会导致血栓形成率增加。在6例中，血栓仅累及插管侧，通过对侧再次插管会漏诊。值得注意的是，9例血栓未累及插管血管，仅累及腔静脉。不影响血栓形成率的因素包括年龄、心脏畸形类型、青紫、早期手术、导管插入时间或球囊房间隔造口术。经皮或切开技术不影响血栓形成率。
