ABSTRACT
This is a case report of the breakage of an umbrella filter 2 years after it had been inserted into the inferior vena cava of a young, active woman. The possible causes of the breakage are discussed. The authors feel that metal fatigue of the ribs of the filter was the most likely cause of the breakage. The varying degrees of intracaval pressure resulting from the normal physical activity of this patient could explain the metal fatigue. the potential dangers of this complication, as well as of other complications associated with the use of this type of device, also are discussed. The authors feel that the age and the likely subsequent physical activity of the patient are important factors to be considered when choosing this modality of treatment for pulmonary embolism.

Polytomography is a simple, noninvasive procedure useful in the diagnosis, preoperative assessment, and follow-up examination of dysphagia due to vertebral osteophytosis. It is especially recommended for all elderly patients undergoing endoscopy to evaluate possible difficulties or hazards which may be encountered due to the presence of osteophytosis. Tomographic study of the esophagus is recommended for all lesions producing dysphagia at the level of the inherently narrowed space of the thoracic inlet, where routine radiography and fluoroscopy are inadequate.

The fear of injurious effects has almost completely halted the use of radiotherapy in the cure of warts. Over a period of 24 years, the authors have treated 531 warts with both orthovoltage and superficial radiation equipment without any adverse effects. The selection of superficial or orthovoltage units was not dependent on the size of the lesion and was thought to be completely random.
