Fibromuscular Disease of the External Iliac Artery

Management of peripheral arterial disease: Role of computed tomography angiography and magnetic resonance angiography

“…Usually a typical aspect of string of bead is seen [51]. However, arterial dissection leading to rupture have been reported [52].…”

Fibromuscular Dysplasia: State of the Science and Critical Unanswered Questions

“…77,78 Lesions below the inguinal ligament are uncommon. Patients with external iliac artery FMD are often asymptomatic, but they may experience claudication or rarely acute limb ischemia.…”

“…Acute limb ischemia resulting from iliac FMD generally occurs in the setting of arterial dissection. 77,79 A bruit caused by iliac FMD may be heard in the lower abdomen from the umbilicus to the inguinal region. In the US Registry, among patients who were referred for an imaging study for suspected lower-extremity FMD (eg, for symptoms or femoral or abdominal bruit), 60% were found to have lesions involving the iliac vessels.…”

Symptomatic Fibromuscular Dysplasia of the External Iliac Artery

“…In 1992, Thevenet et al reported 5 cases (male, 2; female, 3; mean age, 45 [range: 29e53] years) of iliac artery FMD with spontaneous dissection. 16 Of these 5 cases, two presented with intermittent claudication, one with lower-limb acute ischemia, one with abdominal pain, and one with iliac fossa pain. The sites of dissection were in right EIA (n ¼ 3), left EIA (n ¼ 1), and bilateral EIA (n ¼ 1).…”
