Time trends regarding the etiology of renal artery stenosis: 18 years’ experience from the China Center for Cardiovascular Disease

The time trends regarding the etiology of renal artery stenosis (RAS) are changing, but few investigations have focused on these issues. This study aimed to analyze the time trends regarding the etiology of RAS in a large patient sample from the China Center for Cardiovascular Disease. Consecutive inpatients with RAS from January 1999 to December 2016 were enrolled in this study. The etiologic diagnosis of RAS was based on established criteria. We retrospectively analyzed the time trends regarding the etiology of RAS during an 18‐year period. A total of 2905 patients with RAS were enrolled. There were 2393 (82.4%) patients with atherosclerosis (AS), 345 (11.9%) with Takayasu arteritis (TA), 126 (4.3%) with fibromuscular dysplasia (FMD), and 41 (1.4%) with other causes. Among all patients (n = 2905), patients aged ≤ 40 years (n = 450), patients aged >40 years (n = 2455), female patients (n = 1097), male patients (n = 1808), female patients aged >40 years (n = 808), and male patients aged >40 years (n = 1647), there were a gradual increase in the proportion of atherosclerotic RAS (P < 0.05), a gradual decrease in the proportion of RAS caused by TA (P < 0.05), and almost no change in the proportion of RAS caused by FMD during the 18‐year period (P > 0.05). The data show that the primary causes of RAS are AS, TA, and FMD. The proportion of RAS caused by AS and TA gradually increased and decreased, respectively, over time, and the proportion of RAS caused by FMD showed no significant change.

The efficacy of renal artery stent combined with optimal medical therapy in patients with severe atherosclerotic renal artery stenosis

Abstract Objective: To evaluate the efficacy of renal artery stent combined with optimal medical therapy as treatment for renal artery stenosis. Research design and methods: A prospective cohort study was conducted. Patients with severe atherosclerotic renal artery stenosis received percutaneous renal artery stent because of poorly controlled hypertension or preservation of renal function. The patients also received optimal medical therapy to achieve the blood pressure, lipid and blood glucose targets. Main outcome measures: All patients underwent a 12 month follow-up to observe the effect of the procedure on blood pressure control, number of antihypertensive medications and creatinine level. Results: Stents were placed in 185 renal arteries of 149 patients. Mean stenosis was 83.1 ± 7.0%. The success rate of renal artery stent was 99.3%. At 12 months, estimated glomerular filtration rate increased significantly compared with baseline (84.1 ± 28.8 vs. 76.5 ± 22.50 ml/min ×1.73 m2, p < 0.05). Both office blood pressure and 24 hour blood pressure significantly decreased compared with baseline (from 153/83 mmHg to 134/73 mmHg and from 143/80 mmHg to 124/69 mmHg, respectively; p < 0.05), and less antihypertensive medication was taken compared with baseline (1.5 ± 0.8 vs. 2.2 ± 0.9; p < 0.05). Conclusions: Renal artery stent combined with optimal medical therapy as a treatment has a beneficial effect on blood pressure control and estimated glomerular filtration rate in selected patients with atherosclerotic renal artery stenosis. Larger studies with a longer follow-up appear necessary to further confirm these intriguing findings.

Os 35-07 A Novel Method For Adrenal Vein Sampling Via Median Cubital Vein

Objective: Adrenal venous sampling (AVS) is recommended by clinical guidelines to distinguish surgically curable types of primary aldosteronism, but remains widespread underused mainly due to difficulty in successful sampling. When considering that the right adrenal vein is angled caudally, AVS through upper extremity approach may be more appropriate. The purpose of this study was to establish the technique ofAVS via median cubital vein (MCV), and evaluate its safety and feasibility. Design and Method: From January 2012 to June 2015, 194 consecutive patients diagnosed as primary aldosteronism underwent AVS via MCV at the Fuwai Hospital. Patients were assigned to 2 main groups: usual catheterization for bilateral adrenal cannulations (group I, case 1–29), whereas in group2, catheter speicification with MPA1 catheter used for right adrenal vein cannulationand TIG catheter was used for left adrenal vein was done (group II, case 30–194). Group II was further divided into 3 sequential subgroups (group IIa, case 30–84; group IIb, case 85–139; group IIc, case 140–194). Successful sampling was defined by high selectivity index (cortisol in the adrenal vein/cortisol in inferior vena cava ≥ 2). Results: 170 (87.6%) of 194 patients were successful sampled bilaterally. The success rate increased from 79.3% in groupI to 89.1% in group II (P = 0.215) and the three procedure related parameters (the mean time of the procedure, mean fluoroscopy time, and mean dosage of contrast) decreased significantly (all P < 0.001). The successful sampling rate was gradually increased with time in group II (group IIa:87.3%;group IIb:89.1%;group IIc:90.9%), although this did not reach statistical significance. Compared with group IIa, the three parameters were significantly lower in group IIb and IIc (P < 0.05). There was no significant difference between group IIb and IIc (P > 0.05). The incidence of adrenal hematoma and intima injury was 1.0% (2/194) and 1.0% (2/194). Conclusions: This first-in-man study showed AVS via MCV was safe and feasible, with a high rate of successful sampling.
