Dislodged Coronary Stents: The Presnaring Technique.

When dislodged stents remain on the coronary wire, the wire can be snared outside of the body (presnaring), and the snare loop advanced over the wire into the body to retrieve the stent. Presnaring may be a valuable technique to retrieve dislodged coronary stents when the stent remains on the coronary wire, as demonstrated in the 2 patients described.

Thoracic Aortic Aneurysm Presenting as Pulmonary Vein Stenosis: A Case Presentation and Review of the Literature.

We present the case of a 66-year-old woman presenting with pulmonary vein stenosis with a large descending thoracic aortic aneurysm. Pulmonary vein stenosis is a rare condition and can be caused by extrinsic compression, as well as by inflammatory diseases, congenital anomalies and related surgical repair, tuberculosis, and pulmonary veno-occlusive disease. With obstruction to pulmonary vein flow, the velocity increases and becomes continuous.
