Abstract
IVC filters are indicated for patients with documented DVT and contraindication to anticoagulation and patients with recurrent pulmonary embolism despite being on anticoagulation. IVC filters are not recommended for prophylactic placement, free-floating thrombus or prior to systemic thrombolysis. There are two main types of inferior vena cava (IVC) filters: permanent filters and optional (or retrievable) filters. Permanent filters are implanted in patients who require long-term protection against pulmonary embolism (PE) and are unable to take anticoagulant medication due to absolute contraindications. On the other hand, optional filters are designed to be either retrieved or left in place once the temporary risk of PE or contraindication to anticoagulation has resolved. If retrieved, these devices offer potential advantages over permanent IVC filters, including a reduced likelihood of long-term complications such as an increased risk of subsequent DVT, filter migration or embolization, filter perforation and IVC stenosis or occlusion. Aim of work: To study the feasibility and complications of IVC filter retrieval among AMUH patients in which the indication for filter deployment was temporary.
