The incidence of femoral artery spasm and subsequent thrombosis complicating angiography is greater in children than adults. This study was designed to assess femoral artery spasm and to determine its causes in children. In 100 unselected, consecutive infants and children undergoing left heart angiocardiography by the Seldinger technique, angiography of the femoral artery was performed to include the puncture site after completion of angiocardiography. Arterial spasm was quantified and, with mathematical analysis, related to various clinical and angiographic factors. Some degree of arterial spasm was noted in 62% of all cases; it was more frequent and severe in neonates. Although it was more intense in the infant with a small femoral artery, analysis of the data indicates that patient age, weight, length of catheterization, size of femoral artery, and catheter size have only minimal relative importance in the occurrence and severity of arterial spasm. The most important factor in spasm is the relative size of catheter to artery.
股动脉痉挛以及血管造影并发血栓形成的发生率在儿童中高于成人。本研究旨在评估儿童股动脉痉挛并确定其病因。对100例未经挑选、连续接受经Seldinger技术进行左心造影的婴幼儿及儿童，在完成心血管造影后对股动脉进行造影，包括穿刺部位。对动脉痉挛进行量化，并通过数学分析将其与各种临床和血管造影因素相关联。所有病例中有62%出现了一定程度的动脉痉挛；在新生儿中更频繁且严重。尽管在股动脉较小的婴儿中痉挛更强烈，但数据分析表明，患者年龄、体重、插管时间、股动脉大小和导管尺寸在动脉痉挛的发生和严重程度方面相对重要性极小。痉挛最重要的因素是导管与动脉的相对大小。
