“…While patients with FMD have been reported to have aortic aneurysms and dissections, 7 , 8 larger aortic dimensions in the absence of these manifestations have never been identified. The clinical significance of this study’s findings is not yet known but should be investigated in future studies.…”

Background Fibromuscular dysplasia (FMD) is a disease of unknown etiology that causes stenosis, aneurysmal dilatation, and dissection of vascular beds. Known to affect medium‐sized arteries, FMD is not typically considered to affect the aorta. We tested the hypothesis that aortic size in FMD is abnormal compared with age‐ and sex‐matched controls. Methods and Results Medical records and computed tomography angiography images were reviewed in female patients with a diagnosis of FMD who were seen in the vascular medicine clinic at Emory Healthcare. Aortic dimensions were measured at 6 different landmarks. Using 2 sample t tests, the aortic measurements and height‐indexed measurements were compared with published normal values in healthy women of a similar age. A total of 94 female patients were included in the study. The median age was 57 (interquartile range, 50–65). FMD involvement was present most commonly in the extracranial carotid (77.7%) and renal (43.6%) arteries. All 6 aortic segments were found to be larger in both absolute measures and height‐indexed measures in the FMD population ( P <0.001). The largest differences were observed within the absolute measures of the sinotubular junction with mean±SD (mm) (29.9±4.1) versus (27±2.5), ascending aorta (32.7±4.4) versus (30.0±3.5), and descending aorta (24.7±3.0) versus (22.0±2.0) ( P <0.001). Conclusions Aortic diameters in female patients with FMD are larger when compared with published age‐ and sex‐matched normal values. These findings suggest that FMD may also affect the large‐sized arteries.

“… 2 , 7 Case reports describe findings such as aortic aneurysm and/or rupture. 8 Recent data also suggest that patients with FMD have larger common carotid arteries. 9 Thus, the phenotype of FMD is expanding to include vessel tortuosity, aneurysm, and dissection of large vessels as well.…”
