Fibromuscular Dysplasia with Renal or Visceral Artery Dissection
Fibromuscular dysplasia (FMD) can be complicated by dissection of the renal or visceral arteries — a presentation that requires specific antithrombotic management distinct from uncomplicated FMD.
Clinical Scenario
Renal or visceral artery dissection occurring in the context of fibromuscular dysplasia. This complication may be asymptomatic or may manifest as distal thromboembolic events, such as renal or splenic infarction — a finding that directly influences the treatment approach.
Treatment Approach (Partial Overview)
Management centres on antithrombotic therapy; the choice between antiplatelet agents and short-term anticoagulation depends on specific clinical features of the dissection.

Renal or visceral artery dissection may be asymptomatic or present with distal thromboembolic events (e.g. renal or splenic infarct).
If a renal or visceral artery dissection is detected, short-term (e.g. 3–6 months) anticoagulation may be prescribed empirically, particularly in the setting of distal thromboembolic lesions, followed by long-term antiplatelet therapy.
Others prefer antiplatelet therapy (i.e. aspirin alone or in combination with clopidogrel) for initial treatment of renal or visceral artery dissection.
