RESUMEN
PURPOSE: We aimed to compare duration of uterine artery embolization, radiation exposure, safety and quality of life associated with the procedure in patients undergoing uterine artery embolization using transradial and transfemoral access. METHODS: This randomized controlled trial was conducted from February 2013 to March 2017 in three hospitals. Transradial access was used in 78 patients and transfemoral access in 75 patients. Clinical characteristics of the patients were comparable between the two groups. Patients were evaluated for the success and duration of the procedure, radiation exposure, major and minor complications. Quality of life associated with the procedure was assessed among patients with uterine fibroids. RESULTS: Embolization procedures were successfully performed in all patients in both groups. The duration of uterine artery embolization (32.27±7.99 vs. 39.24±9.72 minutes, P < 0.001), uterine artery catheterization time (12.36±5.73 vs. 19.08±6.06 minutes, P < 0.001) and radiation exposure (0.28±0.14 vs. 0.5±0.21 mZv, P < 0.001) were significantly lower in the transradial access group. The rate of major (0% vs. 2.7%, P = 0.37) and minor (11.53% vs. 17.3%, P = 0.42) complications was comparable between the two groups. Transradial access was associated with a statistically significant improvement in the quality of life associated with the procedure among patients with uterine fibroids. CONCLUSION: Transradial access in uterine artery embolization has the same efficacy and safety compared to transfemoral access. This access reduces radiation exposure and duration of the procedure.

Background Factor VII activating protease (FSAP) is of interest as a marker for vascular inflammation and plaque destabilization. The aim of this study was to analyze the expression profile of FSAP in endarterectomy specimens that were taken from patients with asymptomatic and symptomatic carotid atherosclerotic plaques and to compare them with circulating FSAP levels. Methods and Results Plasma FSAP concentration, activity, and mRNA expression were measured in endarterectomy specimens and in monocytes and platelets. Plaque and plasma FSAP levels were higher in symptomatic patients (n=10) than in asymptomatic patients (n=14). Stronger FSAP immunostaining was observed in advanced symptomatic lesions, in intraplaque hemorrhage-related structures, and in lipid-rich areas within the necrotic core. FSAP was also colocalized with monocytes and macrophages (CD11b/CD68-positive cells) and platelets (CD41-positive cells) of the plaques. Moreover, human platelets expressed FSAP in vitro, at both the mRNA and protein levels. Expression is stimulated by thrombin receptor-activating peptide and ADP and reduced by acetylsalicylic acid. Conclusions Plasma FSAP levels were significantly increased in patients with symptomatic carotid stenosis and thus may be involved in plaque development This plaque-associated FSAP may be produced by platelets or macrophages or may be taken up from the circulation. To establish FSAP's utility as a circulating or plaque biomarker in patients with symptomatic carotid atherosclerotic plaques, further studies are needed.
