Why the study?
What is the incidence and clinical presentation of thrombosed Greenfield filters in patients contraindicated for postoperative anticoagulation?
What is the incidence and clinical presentation of thrombosed Greenfield filters in patients contraindicated for postoperative anticoagulation?
Brain tumor patients with Greenfield filters have a high incidence of caval thrombosis, which frequently presents clinically as recurrent deep vein thrombosis.
No takes yet. Share an insight, caveat, or question.
High occlusion rates suggest monitoring for recurrent DVT in brain tumor patients; hypothesis-generating for filter strategies without anticoagulation.
Kolachalam et al. (1990) studied this question.
