Transvenous devices for the management of pulmonary embolism.

When anticoagulant treatment of pulmonary embolism is contraindicated or fails, interruption of blood flow through the inferior vena cava offers an alternative method for preventing further embolic episodes. In the past this required abdominal surgery, but currently several clot-capturing devices have been designed for insertion into the human inferior vena cava indirectly via a jugular or femoral venotomy. Another device is being developed for percutaneous delivery through a standard angiographic catheter. In addition to variations in the delivery methods, the form, mechanical effectiveness, and complications of these differ markedly. A suction-cup device is also available for the transvenous removal of pulmonary emboli.

Postoperative percutaneous kidney stone extraction.

Retained stones may be found in patients who have undergone operations for multiple renal calculi. These stones often produce morbidity and must be removed. The authors describe a technique using a nephrostomy tube, placed during the initial operation, to extract stones percutaneously.

A closed irrigation and drainage system for use with percutaneous abscess drainage: technical note.

A closed irrigation and drainage system has been used in 50 consecutive patients to assess its effectiveness in maintaining catheter patency and draining fluid collections. It consists of an irrigation fluid source, flushing syringe, drainage bag, and tubing to connect the components, and is assembled when the initial drainage procedure is performed. The system emphasizes the use of the siphon effect to maintain constant suction and a closed irrigation and drainage configuration that prevents spread of infection to others and minimizes contamination of the drained cavity. This method of irrigation and drainage also makes patient care considerably easier, and ensures catheter patency.

A nonoperative technique for establishment of a gastrostomy in the dog.

Gastrostomies have been performed nonoperatively under local anaesthesia using a simultaneous percutaneous and endoscopic approach. This technique has been modified to be done under fluoroscopy without the need for endoscopy. The technique and results in five dogs are described.

A comparison of Hexabrix and Renografin 60 in peripheral arteriography.

Fifty-one patients were analyzed after a randomized double-blind study comparing Hexabrix and Renografin 60 in peripheral arteriography. The arteriographic studies and the volumes of contrast material used in both groups were similar. Hexabrix caused significantly less pain and discomfort than Renografin 60, and the diagnostic quality of the radiographs was comparable. A slightly higher incidence of minor side effects was noted in the Hexabrix group, mostly nausea and vomiting and urinary retention.
