Current practices in cerebral venous thrombectomy: A national survey among French interventional neuroradiology centers

Abstract

Background

Cerebral venous thrombosis is a rare but potentially severe condition, with limited evidence supporting venous thrombectomy. This study aimed to assess current practices and perspectives on venous thrombectomy among French interventional neuroradiology (INR) centers.

Methods

In July 2024, a 14-question web-based survey was distributed to INR centers in France through the trainee-led research network, Jeunes En Neuroradiologie Interventionnelle-Research Collaborative. Questions covered center activity, indications, techniques, devices, and perceived complications.

Results

Among the 29 responding centers, half reported performing fewer than three venous thrombectomies per year; one-fourth performed none. Indications for venous thrombectomy were heterogeneous: 77% (n = 20) of centers cited clinical deterioration under anticoagulation, and 58% (n = 15) mentioned coma. Operators most frequently used aspiration techniques (96%, n = 24) and stent retrievers (68%, n = 17) and estimated an immediate partial recanalization (90%, n = 18) without procedural complications (78%, n = 18). All centers expressed interest in participating in a randomized clinical trial assessing the efficacy of venous thrombectomy.

Conclusion

This national survey reveals significant variability in indications and techniques for venous thrombectomy, with a low volume of procedures and strong interest in harmonizing practices through prospective studies.
