Transcatheter Embolization of an Ovarian Artery Pseudoaneurysm: An Elusive Source of Post-hysterectomy Bleeding
AbstractEndovascular management of obstetric and gynecologic hemorrhage has seen the rapid growth of uterine artery embolization for the treatment of symptomatic fibroids, or leiomyomas. However, patients do continue to undergo hysterectomies and are thus prone to the known complications of surgical procedures. We report the case of a 37-year-old woman who underwent a total abdominal hysterectomy for fibroid-related menometrorrhagia. She presented 15 days following this procedure with severe abdominal pain, secondary to a large pseudoaneurysm arising from the right ovarian artery. This was successfully treated with endovascular embolization. This case emphasizes the importance of considering this vessel as a potential source of pelvic hemorrhage following hysterectomy and highlights transcatheter embolization as a suitable management choice
Aortic Arch Morphology and Aortic Length in Patients with Dissection, Traumatic, and Aneurysmal Disease
ObjectivesTo assess aortic arch morphology and aortic length in patients with dissection, traumatic injury, and aneurysm undergoing TEVAR, and to identify characteristics specific to different pathologies.MethodThis was a retrospective analysis of the aortic arch morphology and aortic length of dissection, traumatic injury, and aneurysmal patients. Computed tomography imaging was evaluated of 210 patients (49 dissection, 99 traumatic injury, 62 aneurysm) enrolled in three trials that received the conformable GORE TAG thoracic endoprosthesis. The mean age of trauma patients was 43 ± 19.6 years, 57 ± 11.7 years for dissection and 72 ± 9.6 years for aneurysm patients. A standardized protocol was used to measure aortic arch diameter, length, and take-off angle and clockface orientation of branch vessels. Differences in arch anatomy and length were assessed using ANOVA and independent t tests.ResultsOf the 210 arches evaluated, 22% had arch vessel common trunk configurations. The aortic diameter and the distance from the left main coronary (LMC) to the left common carotid (LCC) were greater in dissection patients than in trauma or aneurysm patients (p < .001). Aortic diameter in aneurysm patients was greater compared with trauma patients (p < .05). The distances from the branch vessels to the celiac artery (CA) were greater in dissection and aneurysm patients than in trauma patients (p < .001). The take-off angle of the innominate (I), LCCA, and left subclavian (LS) were greater, between 19% and 36%, in trauma patients than in dissection and aneurysm patients (p < .001). Clockface orientation of the arch vessels varies between pathologies.ConclusionsArch anatomy has significant morphologic differences when comparing aortic pathologies. Describing these differences in a large sample of patients is beneficial for device designs and patient selection
Development and initial psychometric properties of the WarwickâEdinburgh Mental Wellbeing ScaleâIntellectual Disability version
Background
The WarwickâEdinburgh Mental Wellbeing Scale (WEMWBS; Tennant et al., 2007) is yet to be validated in the intellectual disability (ID) population. The aim of this study was to report the development process and assess the psychometric properties of a newly adapted version of the WEMWBS and the Short WEMWBS for individuals with mild to moderate IDs (WEMWBS-ID/SWEMWBS-ID).
Method
The WEMWBS item wordings and response options were revised by clinicians and researchers expert in the field of ID, and a visual aid was added to the scale. The adapted version was reviewed by 10 individuals with IDs. The measure was administered by researchers online using screenshare, to individuals aged 16+ years with mild to moderate IDs. Data from three UK samples were collated to evaluate the WEMWBS-ID (n = 96). A subsample (n = 22) completed the measure again 1 to 2 weeks later to assess testâretest reliability, and 95 participants additionally completed an adapted version of the adapted Rosenberg Self-Esteem Scale to examine convergent validity. Additional data from a Canadian sample (n = 27) were used to evaluate the SWEMWBS-ID (n = 123).
Results
The WEMWBS-ID demonstrated good internal consistency (Ï = 0.77â0.87), excellent testâretest reliability [intraclass correlation coefficient (ICC) = .88] and good convergent validity with the self-esteem scale (r = .48â.60) across samples. A confirmatory factor analysis for a single factor model demonstrated an adequate fit. The SWEMWBS-ID showed poor to good internal consistency (Ï = 0.36â0.74), moderate testâretest reliability (ICC = .67) and good convergent validity (r = .48â.60) across samples, and a confirmatory factor analysis indicated good model fit for a single factor structure.
Conclusions
The WEMWBS-ID and short version demonstrated promising psychometric properties, when administered virtually by a researcher. Further exploration of the scales with larger, representative samples is warranted

Myocardial fibrosis in asymptomatic and symptomatic chronic severe primary mitral regurgitation and relationship to tissue characterisation and left ventricular function on cardiovascular magnetic resonance
Background: Myocardial fbrosis occurs in end-stage heart failure secondary to mitral regurgitation (MR), but it is not
known whether this is present before onset of symptoms or myocardial dysfunction. This study aimed to characterise
myocardial fbrosis in chronic severe primary MR on histology, compare this to tissue characterisation on cardiovascular magnetic resonance (CMR) imaging, and investigate associations with symptoms, left ventricular (LV) function, and
exercise capacity.
Methods: Patients with class I or IIa indications for surgery underwent CMR and cardiopulmonary exercise testing. LV
biopsies were taken at surgery and the extent of fbrosis was quantifed on histology using collagen volume fraction
(CVFmean) compared to autopsy controls without cardiac pathology.
Results: 120 consecutive patients (64±13 years; 71% male) were recruited; 105 patients underwent MV repair
while 15 chose conservative management. LV biopsies were obtained in 86 patients (234 biopsy samples in total).
MR patients had more fbrosis compared to 8 autopsy controls (median: 14.6% [interquartile range 7.4â20.3] vs. 3.3%
[2.6â6.1], P<0.001); this diference persisted in the asymptomatic patients (CVFmean 13.6% [6.3â18.8], P<0.001), but
severity of fbrosis was not signifcantly higher in NYHA II-III symptomatic MR (CVFmean 15.7% [9.9â23.1] (P=0.083).
Fibrosis was patchy across biopsy sites (intraclass correlation 0.23, 95% CI 0.08â0.39, P=0.001). No signifcant relationships were identifed between CVFmean and CMR tissue characterisation [native T1, extracellular volume (ECV)
or late gadolinium enhancement] or measures of LV function [LV ejection fraction (LVEF), global longitudinal strain
(GLS)]. Although the range of ECV was small (27.3±3.2%), ECV correlated with multiple measures of LV function (LVEF:
Rho=â0.22, P=0.029, GLS: Rho=0.29, P=0.003), as well as NTproBNP (Rho=0.54, P<0.001) and exercise capacity
(%PredVO2max: R=â0.22, P=0.030). Conclusions: Patients with chronic primary MR have increased fbrosis before the onset of symptoms. Due to the
patchy nature of fbrosis, CMR derived ECV may be a better marker of global myocardial status.
