Case ReportsTraumatic intimal tear of the renal artery treated by insertion of a Palmaz stent.
A renal artery intimal injury induced by blunt trauma in a 23-year-old man was treated by percutaneous placement of a Palmaz endovascular stent. The patient was placed on anticoagulation for 2 months following stent insertion. Nuclide renal scans demonstrated recovery of normal renal function on the affected side at 9 months postprocedure.

Embolization of portal-systemic shunts in cirrhotic patients with chronic recurrent hepatic encephalopathy.
To evaluate the efficacy of embolization of portal-systemic shunts in cirrhotic patients with chronic recurrent hepatic encephalopathy (CRHE). ⋯ Transvascular embolization of shunts improved the outcome in 4 of 7 patients. The most effective embolization was achieved via the percutaneous transhepatic portal vein approach.

Case ReportsRight atrial thrombi: percutaneous mechanical thrombectomy.
The current therapeutic options for right atrial thrombi-surgical embolectomy and thrombolysis-are associated with high mortality and such patients often have contraindications to these therapeutic options. The purpose of this study was to evaluate the feasibility of endovascular right atrial embolectomy. Two patients with contraindications to thrombolysis and surgery were treated by a femoral approach. ⋯ The basket was removed leaving the thrombus below the filter. One patient died immediately after the procedure. In conclusion, endovascular extraction of right atrial thrombi may represent a potential therapeutic alternative, particularly in patients with contraindications to thrombolysis and surgery.

The use of inferior vena cava filters in pediatric patients for pulmonary embolus prophylaxis.
To report our experience with inferior vena cava (IVC) filters in pediatric patients. ⋯ IVC filter placement using available devices for percutaneous delivery is technically feasible, safe, and effective in children.

Transfemoral repositioning of malpositioned central venous catheters.
To determine the efficacy of the transfemoral vein approach to repositioning malpositioned central venous catheters. ⋯ Central venous catheters can be repositioned consistently by the transfemoral route. Pigtail catheters or tip-deflecting wires alone are successful in over 80% of cases.
