Insights
Fibromuscular dysplasia (FMD) is frequently associated with recurrent cervical artery dissection (CAD). Patients with FMD experienced a 1% annual rate of symptomatic CAD recurrence, often affecting different arteries.
Area of Science:
- Neurology
- Vascular Medicine
- Radiology
Background:
- The relationship between fibromuscular dysplasia (FMD) and cervical artery dissection (CAD) is not well-established.
- Understanding this association is crucial for managing patients at risk of recurrent cerebrovascular events.
Purpose of the Study:
- To determine the incidence of recurrent CAD (stroke or TIA) in patients with a history of CAD.
- To investigate the association between FMD and the recurrence of CAD.
Main Methods:
- Prospective cohort study of 103 patients admitted for CAD.
- Median follow-up of 4 years.
- CAD diagnosis confirmed by imaging; FMD diagnosed via characteristic "string of beads" pattern on angiography.
Main Results:
- Five patients (4.9%) experienced CAD recurrence, with 60% occurring late.
- Four of the five patients with recurrence had FMD.
- Recurrence involved a different cervical artery in four patients.
Conclusions:
- The annual rate of symptomatic CAD recurrence was 1%.
- FMD was frequently associated with recurrent CAD events.
- These findings highlight the importance of screening for FMD in patients with CAD.
Background:
The prevalence of fibromuscular dysplasia (FMD) in patients with cervical artery dissection (CAD) is unknown. Our objectives were to assess the risk of CAD recurring as a stroke or a transient ischemic attack and the association of these events with FMD.
Methods:
We prospectively included and followed 103 consecutive patients who had been admitted for a CAD. The median follow-up was 4 years (range 4 months to 10 years). The main criteria for inclusion were a mural hematoma demonstrated by cervical magnetic resonance imaging and/or signs suggesting CAD on 2 other investigations. FMD was diagnosed on the so-called string of beads pattern by digital subtraction angiography.
Results:
Five patients had CAD recurrence (60% occurred late). Four of these 5 patients had FMD. In 4 patients, CAD recurrence involved another cervical artery.
Conclusion:
The rate of symptomatic CAD recurrence was 1% per year and was often related to FMD.
