Cystic Adventitial Disease Management in Vascular Systems

Cystic adventitial disease (CAD) is an uncommon non‐atherosclerotic vascular disorder characterised by mucinous cyst formation within the adventitial layer of medium‐sized arteries and veins. Most frequently affecting the popliteal artery, CAD typically presents in middle‐aged individuals—often male—through intermittent claudication or limb swelling without traditional cardiovascular risk factors. The precise aetiology remains debated, with theories invoking degenerative changes, developmental anomalies or synovial extension. Diagnosis relies on high‐resolution imaging: duplex ultrasonography for initial assessment, computed tomography angiography (CTA) and magnetic resonance imaging (MRI) for detailed anatomy, and in selected centres intravascular ultrasound (IVUS) for wall characterisation. Management strategies span from minimally invasive aspiration to definitive surgical repair. Percutaneous cyst evacuation may yield short‐term symptom relief but carries a high recurrence risk. By contrast, open surgical techniques—ranging from cyst excision with adventitial layer resection and patch angioplasty to segmental arterial resection with interposition grafting—offer durable outcomes. Autologous vein grafting remains the gold‐standard reconstructive option in extensive disease. Increasingly, attention has turned to the role of joint connections in atypical locations and the potential for spontaneous resolution in select cases. A multidisciplinary approach, integrating vascular surgery, radiology and rehabilitation, is essential for optimising limb function and minimising recurrence on a global scale.

Technical terms

Adventitia: The outermost connective‐tissue layer of a blood vessel wall.

Claudication: Exercise‐induced pain or cramp in a limb due to inadequate blood flow.

Cystic adventitial disease (CAD): A condition in which mucinous cysts develop within the adventitia, compressing the vessel lumen.

Computed tomography angiography (CTA): Contrast‐enhanced CT imaging used to visualise blood vessels in detail.

Percutaneous transluminal balloon angioplasty (PTA): An endovascular procedure that dilates a narrowed vessel segment using an inflatable balloon.

Intravascular ultrasound (IVUS): A catheter‐based ultrasound technique for imaging the internal structure of vessel walls.
