作者对10例肾移植患者术后平均5个月发生高血压而药物不能控制及肾功能恶化者进行PTA 治疗。10例共有11根肾动脉狭窄,狭窄呈节段性,位于血管吻合处或紧接吻合口远侧,血管腔缩窄55～85%。PTA 均取对侧股动脉途径。使用7F 胶囊导管。胶囊扩张压力为3～4个大气压,扩张3～4次。5例PTA 成功。血管腔平均狭窄从76%降到34%;血压明显下降。其中2例以后发生慢性排异,但血管造影未发现移植肾动脉狭窄。作者指
The author of 10 cases of kidney transplant patients after an average of 5 months of hypertension, drug control and deterioration of renal function in patients with PTA treatment. A total of 11 cases of renal artery stenosis, stenosis was segmental, located in the vascular anastomosis or immediately anastomosis distal, lumen narrowing 55 ~ 85%. PTA take the contralateral femoral artery approach. Use a 7F capsule catheter. Capsule expansion pressure of 3 to 4 atmospheres, expansion 3 to 4 times. 5 cases of PTA success. The average vessel stenosis decreased from 76% to 34%; blood pressure decreased significantly. Chronic rejection occurred after 2 cases, but angiography did not find renal artery stenosis. Author
