Case ReportsStrategies for the management of SVC stent migration into the right atrium.
Stent migration into the right atrium is a potentially fatal complication of stenting in the venous system and is most likely to occur during the treatment of superior vena cava obstruction. Endovascular approaches that can salvage this hazardous situation are described and the keys to successful treatment are highlighted. ⋯ We conclude that prompt management of right atrial stent migration is essential and can be successfully achieved by a variety of "bale-out" techniques which are within the technical range of most interventional radiologists.

Case ReportsEndovascular exclusion of an external carotid artery pseudoaneurysm using a covered stent.
Aneurysmal lesions of the external carotid artery are extremely rare. A case is presented of a 3.8 cm right external carotid artery pseudoaneurysm treated by transluminal exclusion using an endovascular stent-graft. Following stent-graft placement, complete occlusion of the aneurysmal sac and main vessel lumen patency was successfully demonstrated. This report demonstrates the technical feasibility of utilizing stent-grafts to treat aneurysmal lesions involving the external carotid artery.
