The fate of 106 collaterals was investigated following percutaneous transluminal dilatation of 113 stenoses and occlusions. Following dilatation, 78% of collaterals were unchanged and 22% could no longer be demonstrated. The success of the dilatation had no bearing on the fate of the collaterals. Collaterals beginning or ending in a dilated portion of vessel disappeared more frequently (30%) than the others (11%). Following five dilatations, some vessels were demonstrated in the area of stenosis, which had not been demonstrated previously. Evidently local events, such as displacement of arteriosclerotic plaques may lead to occlusion or reopening of vessels. Remaining collaterals may be of great importance in saving a limb if there is an acute occlusion complicating a dilatation.
在对113处狭窄和闭塞病变进行经皮腔内扩张术后，对106条侧支循环的转归进行了研究。扩张术后，78%的侧支循环未发生变化，22%的侧支循环无法再显示。扩张术的成功与否与侧支循环的转归无关。起始或终止于血管扩张段的侧支循环比其他侧支循环更频繁地消失（30%比11%）。经过5次扩张后，在狭窄区域显示出一些之前未显示的血管。显然，局部事件，如动脉粥样硬化斑块移位，可能导致血管闭塞或再通。如果扩张术并发急性闭塞，剩余的侧支循环对于挽救肢体可能非常重要。
