Limitations influencing interventional radiology in Canada: results of a national survey by the Canadian Interventional Radiology Association (CIRA).
To describe the current state and limitations to interventional radiology (IR) in Canada through a large, national survey of Canadian interventional radiologists. ⋯ Interventional radiology in Canada is limited by a number of factors including funding, manpower, and referral support. A concerted effort should be undertaken by individual interventional radiologists and IR organizations to increase training capacity, funding, remuneration, and public exposure to IR in order to help advance the subspecialty.

Follow-up results of 71 patients undergoing metallic stent placement for the treatment of a malignant obstruction of the superior vena cava.
To retrospectively clarify the utility of metallic stent placement for the treatment of the malignant obstruction of the superior vena cava (SVC) in 71 patients with VC syndrome (SVCS) on the basis of long-term follow-up data. ⋯ Stent placement is an effective treatment for SVCS. Further, the utility of S-Z-stent for SVCS, an additional stent for recurrence, unilateral stent for patients with bilateral BCV obstruction, and anticancer therapy after stent placement were verified.

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.
