Case ReportsPercutaneous manual aspiration embolectomy of renal vein thrombosis due to acute pyelonephritis.
We report the case of a 50-year-old man who presented to our institution with septic thrombosis of the renal vein which had not resolved despite several days of antibiotic therapy. Optimal restoration of renal vein flow was obtained by percutaneous manual aspiration embolectomy (PMAE) in this patient with contraindication to fibrinolytic therapy and surgery.

Exclusion of atherosclerotic plaque from the circulation using stent-grafts: alternative to carotid stenting with a protection device?
To retrospectively assess the feasibility, safety, and clinical mid-term outcome of patients undergoing carotid artery stenting with stent-grafts. ⋯ Stent-grafts may prevent microembolic complications during stenting of atherosclerotic carotid lesions in selected cases, offering immediate exclusion of the atherosclerotic lesion from the circulation by pressing the plaque against the vessel wall. Comparative, randomized studies in larger series of patients are needed with carotid-dedicated stent-graft designs.

Case ReportsEndovascular treatment of a bleeding secondary aorto-enteric fistula. A case report with 1-year follow-up.
We report a patient with life-threatening gastrointestinal bleeding caused by a secondary aorto-enteric fistula. Because the patient had several comorbid conditions, we succesfully stopped the bleeding by endovascular placement of a bifurcated aortic stent-graft. The patient developed periaortic infection 4 months later, but he was managed with antibiotics. The patient is well 1 year after the procedure.

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.
