Initial experience in 115 patients with the retrievable Cook Celect vena cava filter

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Device Evaluation

Background:

• Inferior vena cava (IVC) filters are used to prevent pulmonary embolism.
• Retrievable filters offer the potential for removal after the risk period has passed.
• The Cook Celect IVC filter is a retrievable device requiring evaluation of its clinical performance.

Purpose of the Study:

• To assess the performance of the Cook Celect IVC filter.
• Evaluate insertion success, retrieval efficiency, and complication rates.
• Analyze filter dwell times and reasons for retrieval failure.

Main Methods:

• Retrospective review of 115 patients who underwent Cook Celect IVC filter insertion.
• Data collected on filter insertion, retrieval attempts, dwell times, and complications.
• Analysis of successful and failed retrieval cases.

Main Results:

• Successful filter insertion in all 115 patients.
• Overall successful retrieval rate of 49.6% of inserted filters.
• Successful retrieval rate of 93.4% among attempted retrievals.
• Mean dwell time for retrieved filters was 114.9 days.
• Failed retrievals (n=4) were attributed to vena cava thrombosis and filter endothelialization.

Conclusions:

• The Cook Celect IVC filter demonstrates efficacy with a high successful retrieval rate.
• Low complication rates were observed in this patient cohort.
• Filter hook endothelialization is a significant factor limiting successful retrieval.
• Further research is needed to evaluate long-term outcomes and silent complications.
