Iatrogenic arteriovenous fistula with a saclike widening

Acta Angiologica 2019;25(1):14-18.


Iatrogenic pseudoaneurysm affects 2–8% of the population undergoing endovascular therapy. Arteriovenous fistula occurs in about 1–1.5% of patients. Ą very rare combination of the arteriovenous fistula with a large widening resembling a pseudoaneurysm is presented. An ultrasound examination performed at 2 months after an electrophysiological study revealed the presence of an abnormal sac over the right superficial femoral artery. Doppler mapping detected the presence of blood flowing into the sac. Simultaneously, a jet of enhanced blood flow was seen between the anomalous sac and the femoral vein. A contrast-enhanced CT angiography revealed the iatrogenic arteriovenous fistula between the right superficial femoral artery and the femoral vein with the saclike widening. Currently, there is no clear and consistent definition of the complication presented. The patient was referred for surgical management and his further recovery was uneventful.
