Risk factors attributed to failure of ultrasound-guided compression for post-cardiac catheterization femoral artery pseudoaneurysms

Background: Femoral pseudoaneurysm is the most important access site complication following cardiac catheterization. Ultrasound-guided compression repair is a safe and effective therapeutic modality with variable failure rates and risk factors. The aim of this study was to investigate which factors were associated with a higher incidence of ultrasound-guided compression repair failure for post-cardiac catheterization femoral pseudoaneurysm. Methods: Data were retrospectively collected from medical records at King Abdullah University Hospital during the period from January 2011 to December 2016. A total of 42 patients with post-cardiac catheterization femoral pseudoaneurysm had attempted ultrasound-guided compression repair. Data regarding patients, procedure and aneurysm-related factors were evaluated by univariate analysis and multivariate logistic regression. Results: Ultrasound-guided compression repair failed in 31% of the patients. Patients with body mass index of ⩾28 kg/m 2 , platelet count of ⩽180,000/L, time lag (age of aneurysm) of >48 h following puncture time, aneurysmal neck diameter of ⩾4 mm and communicating tract length of  48 h (odds ratio = 5.7), body mass index ⩾ 28 kg/m 2 (odds ratio = 7.8), neck diameter > 4 mm (odds ratio = 14.4) and tract length 48 h, body mass index ⩾ 28 kg/m 2 , wide neck diameter > 4 mm and short aneurysmal communication tract < 8 mm

Factors Affecting Pregnancy Rate Following Fallopian Tube Recanalization in Women with Proximal Fallopian Tube Obstruction

Fallopian tube obstruction is a major cause of female infertility. We aimed to evaluate the factors potentially affecting pregnancy rate following fallopian tube recanalization (FTR) in infertile women with proximal fallopian tube obstruction. Data was retrospectively collected for 61 women (25, primary infertility; 36, secondary infertility) who underwent FTR at our institution. Bivariable and multivariable analyses of clinical pregnancy rates in relation to the following factors were performed: primary vs. secondary infertility, duration of infertility, age at the time of FTR, unilateral vs. bilateral obstruction, and previous pelvic interventions. All women who underwent fluoroscopically guided transcervical FTR of one or both proximally obstructed tubes were successfully recanalized (technical success rate, 100%). Within a year after FTR, 41% of women had conceived. None of the studied variables was significantly associated with pregnancy rate on bivariable analysis. Nevertheless, on multivariable analysis, the type and duration of infertility were significantly associated with pregnancy among women aged &lt;35 years at the time of FTR. Our findings regarding pregnancy rates following FTR reflect the diversity of the patient population and suggest the presence of multiple contributing factors. Younger women with secondary infertility for &lt;5 years are highly likely to achieve conception following FTR
