Treatment of hemodialysis graft pseudoaneurysms with stent grafts: institutional experience and review of the literature.

Hemodialysis access grafts are an important component of the treatment of patients with renal failure. Because access sites are limited, maximizing graft lifespan is of major importance to dialysis patients. Pseudoaneurysm formation is a rare, but important complication potentially limiting the longevity of dialysis grafts.

CT radiographic findings: atrio-esophageal fistula after transcatheter percutaneous ablation of atrial fibrillation.

Introduction: Radio-frequency catheter ablation (RFCA) is an ever increasing modality for treating refractory atrial fibrillation. Radiologists should not only be able to interpret and convey anatomic variations of pulmonary veins and left atrium to referring electrophysiologists, but also should be aware of all the post-RFCA complications and their radiographic findings including this rare, but often fatal complication. This report describes a fatal atrio-esophageal fistula (AEF) involving a normal variant single left common pulmonary vein after transcatheter ablation.
