was 36 ± 18 months. There was a strong positive correlation between the age of AV shunts and their prebanding fistula diameter (r ¼ 0.812, p ¼ 0.05). Mean fistula diameter was 12.20 ± 0.1 and 4.80 ± 0.02 mm before and after access banding, respectively. Real-time cardiac output measured during fistulograms had a mean of 6.40 ± 0.07 and 5.20 ± 0.03 L/min before and after banding. Mean cardiac index was 3.40 ± 0.03 and 2.80 ± 0.02 L/min/m 2 before and after banding. Their average follow-up was 9.8 ± 3.5 months, during which time none of the patients had a relapse of their prebanding presentations. Conclusions: Access banding can be used to decrease cardiac output, as demonstrated by real-time right heart catheterization. This strategy may play a role in the management of heart failure in ESRD patients suspected of having high flow access.
Abstract No. 456Assessing the impact of anticoagulant and antiplatelet therapy for patients undergoing tunneled dialysis catheter interventions: a retrospective review
Results: 31 patients underwent repeat embolization 8 to 97 months after initial embolization. Most patients presented with recurrent menorrhagia (n ¼ 17), pelvic pain/discomfort (n ¼ 7), and urinary symptoms (n ¼ 5). There was a single case presentation of anemia, and one of increasing fibroid size. MR imaging studies were available for 22 of 31 patients and these demonstrated 20 patients with incompletely infarcted fibroids post-initial embolization; one patient had interval enlargement of an existing fibroid and one patient continued to have symptoms despite complete infarction. No new fibroids were identified in this study group. During initial embolization, no patient underwent ovarian artery embolization. During repeat embolization, 6 patients required ovarian artery embolization. Conclusions: Repeat UAE prompted by recurrence of symptomatic fibroids, in particular causing menorrhagia, is often secondary to incomplete infarction. Ovarian artery supply may have contributed to the lack of complete fibroid infarction in a portion of patients however this is not true for the majority of cases in this cohort. The data related to ovarian artery supply is consistent with a prior study from 2006 and therefore further investigation may be indicated to determine additional causes for lack of complete infarction, with the most likely cause being early vascular recanalization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
