Endovascular Coiling Combined With Tissue Glue Embolism to Treat 20 Cases of Iliac Arteriovenous Fistula Secondary to Deep Vein Thrombosis.

Objective: The objective of this study is to assess the feasibility of endovascular coiling combined with tissue glue embolism for the treatment of iliac arteriovenous fistula (AVF) secondary to deep vein thrombosis (DVT) of the lower extremities. In addition, we aim to summarize the treatment methods and enhance understanding of the disease.

Methods: This research analyzes the clinical data and medical imaging materials of 20 cases with iliac AVF secondary to lower extremity DVT, ranging from December 2014 to December 2020, at our hospital. The patients underwent endovascular coiling and tissue glue embolism during their hospital stay. We collected and summarized the clinical and imaging data, evaluated the efficacy of treatment methods, assessed the incidence of complications, and conducted long-term follow-up observations.

Results: All 20 surgeries were successful. Endovascular coiling combined with tissue glue embolism significantly relieved limb swelling. The diameter difference above the patella in patients before and after treatment was 9.38±3.58 versus 4.13±1.64 cm, <0.001. No serious complications occurred during treatment, and no patients showed signs of AVF recurrence during follow-up after surgery.

Conclusion: Endovascular coiling combined with tissue glue embolism can be used to treat iliac AVF secondary to DVT of the lower extremities, which has high clinical value and is safe.

Clinical Impact: For clinicians, AVF secondary to DVT is a complication that cannot be ignored. It also needs to be treated aggressively to improve patients' quality of life. We presented a minimally invasive method to treat iliac arteriovenous fistula secondary to deep vein thrombosis of lower extremities, which is also an innovative intervention technique. Endovascular coiling combined with tissue glue embolism can achieve better embolic blockade in this type of iliac arteriovenous fistula. This will move the management of postoperative complications in the direction of minimally invasive.
