title: Successful removal of a Gunther tulip vena cava filter with wall-embedded hook and migration during a retrieval attempt.
abstract: Retrieval of a Gunther tulip vena cava filter implanted in a patient with inferior vena cava and right common iliac vein thrombosis was attempted by the standard method. Because the filter was tilted, the hook became attached to the vena cava wall and could not be snared. During attempts at removal by an alternative method, the filter migrated toward the right atrium. However, it was finally successfully removed.
