RESUMO
Simon nitinol vena caval filters were placed percutaneously in 20 patients. Follow-up (average, 14 months) data were available for 16 patients, and four patients were lost to follow-up. There were no proved or suspected cases of pulmonary embolism after filter insertion. Complications encountered included caval penetration (n = 5, one acute and four at follow-up), caval thrombus (n = 4, two determined radiologically and two clinically), postplacement deep venous thrombosis (n = 2, one radiologic and one clinical), filter migration (n = 1), and delayed fracture of a filter leg (n = 2). Although no deaths or significant morbidity resulted from any complication, the relatively high complication rate, especially of significant caval penetration (documented in 25% of filter insertions), merits continued short- and long-term assessment of patient status after filter placement.

The atypical appearance of a gas-containing, noninfected, popliteal synovial cyst has been presented. The case again demonstrates the value of plain radiographs, in this instance in distinguishing gas bubbles and calcification, which may not be apparent by MRI and ultrasound. The uniqueness of this case is stressed. The cause of the gas bubbles was not ascertained.

Transluminal angioplasty, particularly of stenoses of the iliofemoral arteries, is an excellent technique with a success rate greater than 90%, an overall complication rate of less than 5%, and a low incidence of major complications. Of these major complications, arterial rupture is one of the most urgent. We have presented a case of external iliac artery rupture during angioplasty that graphically demonstrates the value of balloon tamponade in managing this potentially catastrophic event. The angiographer's sensitivity to the possibility of arterial rupture and prompt management, combined with close collaboration with the vascular surgeon, can lead to a good clinical outcome.

Limb-lengthening procedures are being performed at an increasing rate in the United States. A successful outcome relies heavily on serial radiologic evaluation. Therefore, it is important for radiologists to become familiar with the various techniques, their normal radiologic appearance, and associated complications. Lengthening by the Wagner method, distraction epiphysiolysis, and the Ilizarov technique are illustrated. Chondrodiatasis and callotasis also are discussed.

Chronic renal failure often results in bone changes, collectively known as renal osteodystrophy. These changes include osteitis fibrosa, osteosclerosis, soft tissue calcifications, osteomalacia (in adults) and rickets (in children). Early recognition of renal osteodystrophy allows more aggressive clinical control of serum calcium and phosphate levels. Intervention may spare the patient late complications such as fractures, pain and loss of skeletal function.
