The Mobin-Uddin inferior vena cava umbrella-filter is an ingeniously engineered device for the prevention of further pulmonary embolism in critically ill patients having embolism after anticoagulant therapy or in whom anticoagulants are contraindicated. The clear advantage of this method over the direct operative application of a serrated external clip is that local anesthesia can be used and the cardiovascular-pulmonary effects of general anesthesia avoided in very ill patients.
Mobin-Uddin recently reported the preliminary results of a cooperative series of 400 patients in whom his method had been used.1 Untoward results to date included recurrent embolism (eight), filter migration to the right auricle or pulmonary artery (five), implantation of the filter into the renal vein (three), implantation of the filter into an iliac vein (four), retroperitoneal hematoma (two), and duodenal perforation (one). In 116 personal cases, Mobin-Uddin noted recurrent embolism in four, iliac vein placement in one, and inability to
