Cystic adventitial disease (CAD) is a rare vascular disorder, predominantly seen in young healthy men with minimal cardiovascular risk factors. Cystic adventitial disease can affect both arteries and veins. Patients with arterial CAD present with sudden onset or rapidly progressing claudication symptoms, and those with venous CAD present with limb swelling or very rarely deep vein thrombosis. Diagnosis is confirmed with the aid of imaging techniques such as ultrasonography, computed tomography, or magnetic resonance scan. Surgical resection or evacuation of the lesion is usually the preferred approach, with only mixed results reported for percutaneous endovascular techniques.

BackgroundPercutaneous endovascular aneurysm repair (PEVAR) has been shown to have high success rates, shorter operating times and length of stay compared to open access. However, there exists a lack of long-term follow-up data on these patients, and questions remain regarding longer-term outcomes. This study aims to assess the long-term complications and evolution of accessed vessels post-PEVAR.MethodsSixty-one cases of bilateral PEVAR (122 groins) with > 36 months follow-up were analysed. Vessel diameter, calcification, dissection, lymphocele, pseudoaneurysm and thrombus formation were reviewed at 30th day and at the most recent follow-up CT. Notes were reviewed for groin infections, haematomas and nerve injury. Complications were considered ‘major’ if they required intervention or treatment.ResultsMean follow-up time from procedure to most recent scan was 49.9 months. There were no major short- or long-term complications. The early complication rate was 9.8%, with six pseudoaneurysms, four dissections, one thrombus, one nerve injury and no lymphoceles, haematomas or groin infections. The long-term complication rate was 0.8%, with only one pseudoaneurysm. The remainder of early complications resolved naturally without intervention. Accessed vessel showed significantly (P ≤ 0.05) increased diameter and calcification between 30th day and last follow-up scan.ConclusionThis study provides the largest clinical cohort and the longest mean follow-up time reported in the literature and demonstrates the long-term safety of PEVAR. PEVAR has a very low long-term complication rate, without any major complications in our cohort. The accessed common femoral arteries do not show stenosis or thrombosis. Minor short-term complications appear to gradually resolve without intervention. Larger multi-centre studies are recommended.
