摘　　要：　　目的　对亲体肾移植供肾者血管的影像学诊断方法进行了评价。方法　 30例亲体肾移植供肾者中12例行MSCTA, 10例行肾动脉DSA, 4例行非增强MRA, 3例同时行MSCTA和DSA, 1例同时行DSA和非增强MRA。结果　30例供肾者显示肾动脉 68支,其中 1例左肾动脉早期分支。15例CTA检查中, 13例双肾单支动脉供血,其中 1例左肾动脉分支早,且为双肾盂双输尿管畸形; 1例右肾见 1支副肾动脉, 1例左肾见 1支副肾动脉。有 3例同时做了DSA检查,与CTA显示相似,为单支肾动脉。14例DSA检查, 8例双肾均为单支动脉, 4例一侧见副肾动脉,右侧 2例,左侧 2例。5例行非增强MRA检查, 3例双肾均为单支动脉, 1例左肾见 1支副肾动脉,而右侧 1支副肾动脉未能显示清楚,另 1例右侧肾 1支副肾动脉也未能显示清楚。结论　术前对亲体肾移植供体肾血管行MSCTA和DSA检查结果与手术所见相一致,较非增强MRA检查准确。而MSCTA以其快捷、方便、价廉及无创的优势可以取代DSA。Objective To evaluate the various imaging methods for renal arteries of living renal donors.Methods Among 30 cases, multislice spipral computed tomography angiography(MSCTA) was performed in 12 cases,digital substraction angiography (DSA) in 10 cases,non-enhanced magnetic resonance angiography (MRA) in 4 cases,both CTA and DSA in 3 cases,and DSA and non-enhanced MRA in one case.Results 68 renal arteries were displayed in 30 cases.CTA in 15 cases demonstrated bilateral kidney to be all supplied by single artery in 13 patients,of them,one of left renal artery divided early than normal in company with deformity of double renal pelvis and renal duct,another 2 patients had accessory arteries in left renal and right renal respectively,3 cases were undergone DSA simultaneously which showed the similar results as CTA.DSA in 14 cases displayed bilateral renal solitary artery in 8 patients and accessory arteries in 4 patients.MRA showed bilateral renal solitary artery in 3 patients and accessory artery in two cases.Conclusion The appearances of preperative CTA and DSA examination of the renal arteries in renal donors are corresponding to that in surgery and more accurate than that showed on non-enhanced MRA.Moreover,CTA can substitute DSA for its quickness,convience,cheapness and no injury.
