Massage-induced delayed venous stent migration.

Catheter-directed therapies in chronic deep vein thromboses can help improve leg function by mechanically addressing residual obstruction in lower extremity or pelvic veins, although the reported use of stents in leg veins is relatively unusual. The author reports a case of this type with long-term patency and clinical success, culminating in asymptomatic delayed venous migration of a stent to the right atrium after 3 years. Open heart surgery was required to remove the embedded stent fragments. The attributed mechanism was deep tissue massage of the thigh.
