Congenital anomalies of the inferior vena cava and left renal vein: evaluation with spiral CT.
To determine with spiral computed tomography (CT) the incidence and caval location of left renal vein (LRV) variants that may affect inferior vena cava (IVC) filter placement, spermatic vein embolization, and adrenal or renal venous sampling. ⋯ Detailed knowledge of these anomalies is crucial for IVC filter placement, spermatic vein embolization, and adrenal or renal venous sampling.

Case ReportsMycotic aneurysms of the thoracic aorta: repair with use of endovascular stent-grafts.
Standard therapy of mycotic aneurysms in the descending aorta consists of thoracotomy and in situ graft placement or extraanatomic bypass. The alternative use of endovascular stent-grafts was evaluated for management of infected aneurysms of the thoracic aorta. ⋯ Endovascular stent-grafts combined with antibiotic therapy may be an alternative to conventional thoracotomy in managing mycotic aneurysms of the descending thoracic aorta.

Percutaneous radiofrequency tissue ablation: does perfusion-mediated tissue cooling limit coagulation necrosis?
To determine, by decreasing hepatic perfusion during radiofrequency (RF) ablation, whether perfusion-mediated tissue cooling can explain the reduced coagulation observed in in vivo studies compared to that seen with RF application in ex vivo tissue. ⋯ Perfusion-mediated tissue cooling reduces coagulation necrosis achievable with RF ablation. Reduction of blood flow during RF application increases coagulation in both an animal model and human liver metastases.

Experience with 100 consecutive central venous access arm ports placed by interventional radiologists.
This study reports the authors' experience with long-term follow-up of 100 consecutive peripherally inserted, subcutaneous arm ports for central venous access. ⋯ Subcutaneous arm ports placed by interventional radiologists are effective for central venous access with excellent functionality (93.8% achieved a successful long-term outcome) and a very low procedural complication rate. Although infections were more frequent in HIV-infected individuals, these devices are associated with a very low incidence of both immediate and long-term complications, including infection, for all patients.
