Use of intravascular ultrasound to determine relationship between renal artery remodeling and renovascular hypertension / 中华超声影像学杂志

ABSTRACT

50%) were divided into two groups,including 10 hypertensive (Group I) and 11 normotensive patients (Group II).Renal artery intravascular ultrasound was performed in all cases to obtain the ultrasound image of renal artery lesion.Renal venous blood of both stenotic and contra lateral sides was collected to measure the levels of renin and renal vein renin rate(RVRR).The results were compared respectively.Results There were no differences in the numbers of adaptive remolding (5 vs 7) and coarctation (5 vs 4) between the two groups.The cross sectional area of external elastic membrane [( 128.3 ? 29.5 )mm 2 vs ( 111.8 ? 30.4 )mm 2],the plaque area [( 94.4 ? 26.2 )mm 2 vs ( 79.6 ? 28.5 )mm 2] and the luminal stenosis ( 73.3 ? 6.7 )% vs ( 67.9% ? 11.2 )% were higher in Group I than those in Group II,but did not achieve statistical significance.The RVRR( 2.79 ? 0.57 vs 1.09 ? 0.28 ) in Group I,however,was significantly higher than that in Group II (P
