[The measurement of vascular diameter to determine stent and balloon size in percutaneous procedures in the pelvic circulation].
OBJECTIVE
Should the sizes of balloons and stents used in the pelvic circulation be determined by the size of the ipsilateral or contralateral vessel?


METHODS
The angiographic findings in 31 patients were analysed; in 10 an occlusion and in 21 a high grade stenosis (greater than 75%) of the common iliac artery had been treated by stenting (26) or simple PTA (5).


RESULTS
In 26 of the 31 patients there was marked reduction in the lumen distal to the lesion up to 40%. In 17 patients this was reversed immediately after the procedure and in five others the lumen increased but a difference between the two sides remained. The changes on the two sides following treatment were statistically significant (external iliac artery: p = 0.00013).


CONCLUSIONS
The results indicate that the "normal" contralateral measurements should be used rather than the distal ipsilateral vessel diameter.
