  renal artery stenosis
Background: The importance of renal artery stenosis as a cause of refractory hypertension, recurrent pulmonary edema and renal failure is being increasingly recognized.
      
The four patients with critical renal artery stenosis underwent primarily successful PTA and stenting.?Conclusions: Selective renal angiography in the wake of coronary angiography is safe and inexpensive.
      
The diagnostic yield of renal angiography ist not negligible; 2% of patients had critical renal artery stenosis with an unequivocal indication for an interventional procedure.
      
Progression of (as yet) nonsignificant renal artery stenosis is reported in a large number of cases, meaning that early diagnosis may have later therapeutic consequences.
      
Ad hoc PTA and stenting is the treatment of choice for significant renal artery stenosis.

  renal arterial stenosis
All 380 hypertensive patients in the study underwent renal arteriography; 125 had renal arterial stenosis ≥ 70%, and 54 had a technically successful intervention to correct the stenosis.
      
A total of 11 patients had renal arterial stenosis, associated with narrowing of other aortic segments in 10 cases.
      
Isolated renal arterial stenosis was rare, since it was more frequently combined with a narrowed aorta.
      
Since in both of our patients, the renal arterial stenosis was very severely or almost totally occlusive, we could not perform percutaneous transluminal renal artery angioplasty, and therefore nephrectomy was the only option.
      
A case of a young patient with mild coarctation of the thoracic and abdominal aorta associated with bilateral renal arterial stenosis is reported.

  renal artery stenoses
Catheter-dilatation (Percutaneous Transluminal Angioplasty=PTA) of renal artery stenoses can be applied successfully and without major risk even in patients with high operative risks.
      
In 18 (16.4%) patients renal artery stenoses by which the lumen was narrowed for more than 30% and in 2 (1.8%) patients occlusions of one renal artery were found, all of which seemed to be of arteriosclerotic origin.
      
12 (60%) patients with renal artery stenoses or occlusions showed arterial hypertension (RR 171±33/94±16 mmHg) inspite of adequate antihypertensive medication, 8 were normotensive even though renal artery stenoses were found angiographically.
      
On the other hand 30 (33%) of the 90 patients without renal artery stenoses were hypertensive (RR 165±15/93±9 mmHg).
      
These data support the observation that renal artery stenoses must not result in hypertension, but clearly indicate the higher prevalence of hypertension in patients with renal artery stenoses or occlusions.

Four female patients of renal autotransplantation for renal artery stenosis with malignant hypertension had been followed for more than three years,with two of them,for 8 years.Their blood pressure had all returned

对4例因肾动脉狭窄引起恶性高血压妇女的自体肾脏移植进行了3年以上的随访,其中两例已8年之久,血压全部恢复到正常范围,并且排泄性肾盂造影显示了正常功能和解剖形态。2例女青年术后结婚,并且无任何并发病足月生了孩子。2例术后3个月高血压复发,其中1例动脉造影显示动脉吻合处狭窄,可是术后6~8个月血压又全恢复了正常。

From 1980 to 1986, 7 cases of renal vascular hypertension (RVH) were diagnosed and treated. Four cases were renal artery stenosis (RAS) on the right side and 3 cases were RAS on both sides. Right renal transplantation succeeded in all cases. Of the 3 cases of bilateral RAS, their left RAS were cured by percutaneous transluminal angioplasty (PTA) with Gruntzig balloon catheter. Blood pressure returned to normal range in all these 7 cases within 8 days post -operati-yely.These cases were followed up for 10 months...

From 1980 to 1986, 7 cases of renal vascular hypertension (RVH) were diagnosed and treated. Four cases were renal artery stenosis (RAS) on the right side and 3 cases were RAS on both sides. Right renal transplantation succeeded in all cases. Of the 3 cases of bilateral RAS, their left RAS were cured by percutaneous transluminal angioplasty (PTA) with Gruntzig balloon catheter. Blood pressure returned to normal range in all these 7 cases within 8 days post -operati-yely.These cases were followed up for 10 months to 6 years, their blood pressure all remained normal and all of them resumed their original work. One 17-year-old girl was married 2 years after operation, and gave birth to a female baby 2 years later. Both the mother and the baby were in safty and no influence was seen on her blood pressure.

自1980到1986年,我院泌尿外科对4例单纯右侧肾动脉狭窄(RAS)性和3例双侧RAS性高血压病人进行了治疗。7例右侧 RAS皆进行了自体肾移植治疗,其中3例双侧RAS者采用PTA治疗,全部病人术后8天内血压皆恢复正常,随诊10个月到6年,无复发且都恢复工作。1例17岁女孩,术后2年结婚,又2年生一女孩,母女健在血压维持正常。

Rapid-sequence intravenous excretion urography and plasma renin activity (in peripheral and renal venous blood) measurement were performed in 23 patients with renovascular hyperension and 15 patients with essential hypertension demonstrated by renal arteriography. The results showed that rapid-sequence intravenous excretion urography was a safe and useful screening procedure for renovascular hypertention in patients with high blood pressure.

Rapid-sequence intravenous excretion urography and plasma renin activity (in peripheral and renal venous blood) measurement were performed in 23 patients with renovascular hyperension and 15 patients with essential hypertension demonstrated by renal arteriography. The results showed that rapid-sequence intravenous excretion urography was a safe and useful screening procedure for renovascular hypertention in patients with high blood pressure. The criteria used for its diagnosis should be the presence of two or more of the four abnormalities in rapid-sequence intravenous excretion urography. It became useful only when plasma renin activity in peripheral venous blood had no value in screening renovasular hypertention, combined with the renin activity measurement of the blood in the lateral renal vein. In concllusion, rapid-sequence excretion urography is a safe and useful screening procedure for renovascular hypertension in patients with high blood pressure, especially when combined with plasma renin activity measurement.

本文对23例肾动脉狭窄性高血压患者作肾动脉造影,快速静脉尿路造影和血浆肾素活性(包括外周静脉、肾静脉、下腔静脉),并有肾动脉正常的原发性高血压15例进行对比分析,显示快速静脉尿路造影是安全而可靠的筛选检查方法之一,如果以二项或二项以上阳性作标准,则可减少假阳性。血浆肾素活性测定,单项指标阳性意义不大,假阳性与假阴性都很多。若二项或二项以上阳性,则可减少假阳性,因此,如与快速静脉尿路造影结果合并考虑,则诊断意义更大。
