Technical and Anatomic Factors Influencing the Success of Inferior Vena Caval Stent Placement for Malignant Obstruction.
To evaluate the outcomes of inferior vena cava (IVC) stent placement for malignant obstruction and to identify anatomic and procedural factors influencing technical and clinical success. ⋯ Stent placement is reliable, rapid, and durable in improving malignant IVC syndrome. Understanding of technical and anatomic factors can improve accuracy and avoid complications of stent misplacement.

Percutaneous Cryoablation for the Treatment of Primary and Metastatic Lung Tumors: Identification of Risk Factors for Recurrence and Major Complications.
To identify risk factors for local recurrence and major complications associated with percutaneous cryoablation of lung tumors. ⋯ Percutaneous cryoablation of lung tumors is technically feasible with a complication rate comparable to other percutaneous ablation techniques. Percutaneous cryoablation is more efficacious and has fewer complications when offered to patients with small, previously untreated lesions.

Randomized Controlled Trial Multicenter Study Comparative StudyProspective, Randomized, Concurrently-Controlled Study of a Stent Graft versus Balloon Angioplasty for Treatment of Arteriovenous Access Graft Stenosis: 2-Year Results of the RENOVA Study.
To present final, 2-year data from randomized comparison of an expanded polytetrafluoroethylene stent graft (SG) and percutaneous transluminal angioplasty (PTA) for treatment of arteriovenous graft (AVG) anastomotic stenoses. ⋯ At 2 years, SG use provided a sustained, greater than 2-fold advantage over PTA in treatment area and overall access patency. Time to subsequent intervention was longer in the SG group.

Catheter-Directed Intraarterial Thrombolysis as Part of a Multidisciplinary Management Protocol of Frostbite Injury.
To evaluate intraarterial catheter-directed thrombolysis for prediction and prevention of delayed surgical amputation as part of multidisciplinary management of frostbite injury. ⋯ Intraarterial catheter-directed thrombolysis should be included in initial management of frostbite injury, as it may prevent delayed amputations. The degree of angiographic response to thrombolysis can potentially predict amputation outcomes.

Comparative StudyIndwelling and Retrieval Complications of Denali and Celect Infrarenal Vena Cava Filters.
To compare indwelling and retrieval complications of Denali and Celect filters placed in the infrarenal inferior vena cava (IVC). ⋯ This study suggests that Denali filters are associated with lower incidences of strut penetration and filter tilt as well as shorter fluoroscopy time at retrieval compared with Celect filters when placed in the infrarenal IVC.
