Percutaneous retrieval of migrated Viabahn stent from a segmental pulmonary artery
1Department of Diagnostic and Interventional Imaging, University of Texas Health Science Center at Houston, McGovern Medical School, 6431 Fannin St, MSB 2.132, Houston, TX 77030 USA.
Background:
With improving and aggressive endovascular venous and dialysis techniques there is increasing use of stent grafts with different platforms available on the market. Inappropriately sized stents may displace and potentially end up in the heart or lungs as potential dangerous foreign bodies. There is single published case of successful viabahn stent graft retrieval from the pulmonary circulation.
Case Presentation:
We present a patient who had successful safe percutaneous retrieval of a migrated Viabahn stent from a segmental Pulmonary artery and describe a different novel safe technique of successful stent graft retrieval from the pulmonary artery with very low risk to potential damage to the cardiac valve complex.
Conclusion:
This case report demonstrates that Viabahn stent grafts can be safely retrieved from the pulmonary arterial system using this endovascular technique that will significantly reduce the risk of damage to the cardiac valve complex therefore avoiding potential complex surgery.
