Multicenter StudyPrimary cutting balloon angioplasty for treatment of venous stenoses in native hemodialysis fistulas: long-term results from three centers.
To evaluate the technical success and patency rates following primary cutting balloon angioplasty for venous stenoses in native dialysis fistulas. ⋯ PCB angioplasty has high technical success and low complication rates. The long-term patency rates are favorable for PCB angioplasty and compare favorably with other series.

Case ReportsEmergency stenting of a ruptured infected anastomotic femoral pseudoaneurysm.
A 74-year-old man presented with a ruptured infected anastomotic femoral pseudoaneurysm. Due to severe medical comorbidities he was considered unsuitable for conventional surgical management and underwent an emergency endovascular repair with a balloon-expandable covered stent. ⋯ To our knowledge, emergency endovascular treatment of a free ruptured bleeding femoral artery pseudoaneurysm has not been documented before in the English literature. This case illustrates that endovascular therapy may be a safe and efficient alternative in the emergent management of ruptured infected anastomotic femoral artery pseudoaneurysms when traditional open surgery is contraindicated.

Endovascular treatment of lower limb penetrating arterial traumas.
The purpose of this study was to evaluate the effectiveness of percutaneous arterial embolization in patients with penetrating peripheral arterial trauma. ⋯ We conclude that embolization-particularly n-butyl cyanoacrylate embolization-is technically feasible in patients with penetrating peripheral arterial trauma.

Early results of endovascular treatment of the thoracic aorta using the Valiant endograft.
Endovascular repair of the thoracic aorta has been adopted as the first-line therapy for much pathology. Initial results from the early-generation endografts have highlighted the potential of this technique. Newer-generation endografts have now been introduced into clinical practice and careful assessment of their performance should be mandatory. ⋯ Comparison with a series of earlier-generation grafts demonstrated a significant increase in complexity of procedure as assessed by graft implantation site, number of grafts and patient comorbidity. The data demonstrate acceptable results for a new-generation endograft in series of patients with diverse thoracic aortic pathology. Comparison of clinical outcomes between different endografts poses considerable challenges due to differing case complexity.
