ABSTRACT

Objective:

To evaluate the impact of renal artery stenting techniques upon anatomical correlation of abdominal aorta and renal artery.

Methods:

A total of 182 patients with unilateral atherosclerotic renal stenosis and received renal artery stenting in our hospital from 2012-01 to 2013-12 were retrospective studied. Based on the angle of infrarenal abdominal aorta and renal artery, the patients were divided into 3 groups Group A (91-120)°, n=20, Group B (61-90)°, n=125 and Group C, (30-60)°, n=37. According to the tortuosity of infrarenal abdominal aorta and/or iliac artery, the patients were divided into 2 groups Non-tortuosity group, n=146 and Tortuosity group, n=36. Operative techniques included in ①wire anchoring alone, ②wire anchoring+balloon rod assisting and③anchoring with wire and balloon. The ratio of upper extremity artery approaching (brachial or radial artery), X-ray exposure time, operation time, contrast dosage and relevant complications were compared among different groups upon stent placing.

Results:

Compared with Group A and Group B, the following parameters were increased in Group C ratios for using technique ② + ③ (100.0% vs 20.0%, 31.2%), for extremity artery approaching (10.8% vs 0.0%, 1.6%); X-ray exposure time (9.2±3.8) min vs (5.2±3.1) min, (5.3±2.8) min, operation time (27.4±6.5) min vs (18.6±5.7) min, (20.5±6.1) min; contrast dosage (59.3±8.4) ml vs (44.8±7.2) ml, (48.4±7.3) ml and the incidences of relevant complications (8.1% vs 0.0%, 0.8%), all P<0.05. The above parameter were similar between Group A and Group B. Compared with Non-tortuosity group, the following parameters were elevated in Tortuosity group ratios for using technique ②+③ (72.2% vs 11.6%), for extremity artery approaching (11.1% vs 1.4%), the total incidences of X-ray exposure time, operation time, contrast dosage and relevant complications (8.3% vs 0.7%), all P<0.05.

Conclusion:

The acute angle of infrarenal abdominal aorta and renal artery as well as the tortuosity of infrarenal abdominal aorta may increase the difficulty in renal artery interventional therapy .
