副肾动脉直径与肾血管性高血压的相关性

Correlation between diameter of accessory renal artery and renovascular hypertension

目的探讨副肾动脉(ARA)直径与肾血管性高血压的关系。方法回顾性分析28例肾血管性高血压伴ARA患者及81例存在ARA但无高血压者,采用MSCTA观察ARA的支数、起源及走行。测量ARA直径,分析ARA直径与肾血管性高血压的关系。结果病例组年龄(30.6±7.5)小于对照组(49.1±13.1),差异有统计学意义(P<0.05)。病例组及对照组共检出133支ARA,其中右侧62支(62/133,46.62%),左侧71支(71/133,53.38%)。89支(89/133,66.92%)ARA主要起源于腹主动脉,41支(41/133,30.83%)为早发分支,另有2支(2/133,1.50%)起源于肠系膜下动脉,1支(1/133,0.75%)起源于肠系膜上动脉。109例中,1支型89例(89/109,81.65%),2支型17例(17/109,15.60%),3支型2例(2/109,1.83%),4支型1例(1/109,0.92%)。病例组ARA直径与同侧肾动脉直径比值(0.87±0.11)大于对照组(0.33±0.13),双侧肾动脉直径比值(0.71±0.17)小于对照组(0.94±0.05),二者差异均有统计学意义(P均<0.05)。结论 MSCTA检查能够清晰显示ARA支数、起源及走行。ARA直径粗大与肾血管性高血压有关。

Objective To explore the correlation between diameter of accessory renal artery（ARA）and renovascular hypertension.Methods Totally 28 renal hypertension patients with ARA and 81 ARA patients without hypertension（hypertension group）were analyzed retrospectively（control group）.The number,origin and the trace were observed by the MSCTA technology.The diameter of ARA was measured and then the relationship between ARA diameter and renovascular hypertension was analyzed.Results The age in hypertension group（30.6±7.5）was younger than that of control group（49.1±13.1,P〈0.05）.A total of 133 ARA were found in hypertension group and control group,including the left ARF 71（71/133,53.38%）and the right ARA 62（62/133,46.62%）.There were 89（89/133,66.92%）ARA mainly originated from the abdominal artery,and 41（41/133,30.83%）ARA originated from the early-onset branch.There were 2（2/133,1.50%）branches originated from the udder mesenteric artery and 1（1/133,0.75%）branch from the upper mesenteric artery.Among the 109 cases,89cases（89/109,81.65%）of one branch type,17（17/109,15.60%）of two branches type,2（2/109,1.83%）of three branches type and 1（1/109,0.92%）of four branches type were found.The diameter ratio between ARA and homolateral renal artery in the hypertension group（0.87±0.11）was more than that of the control group（0.33±0.13,P〈0.05）,the diameter ratio between bilateral renal arteries in the hypertension group（0.71±0.17）was less than that of the control group（0.94±0.05,P〈0.05）.Conclusion The MSCTA technology could be used to show the number,origin and the trace of ARA.The thicker ARA is closely related to the renovascular hypertension.
