The issue of spontaneous arteriovenous fistulae after superficial thrombophlebitis, endovenous ablations, and deep vein thrombosis: an unusual but predictable finding.

Spontaneous arteriovenous fistulae develop after the formation of venous thrombi in animals. In patients who have undergone endovenous ablation, angiogenesis occurs. This study was undertaken to examine the clinical presentation, development, and effects of spontaneous arteriovenous fistulae in patients with venous thrombosis.
