A Comparison of Retrievability: Celect versus Option Filter.

Area of Science:

• Vascular Surgery
• Medical Device Technology
• Interventional Radiology

Background:

• Inferior vena cava (IVC) filters are crucial for preventing pulmonary embolism.
• Retrievable IVC filters offer a temporary solution, necessitating effective retrieval methods.
• Device design significantly impacts filter retrieval success and safety.

Purpose of the Study:

• To compare the retrievability of two potentially retrievable IVC filter devices: Celect and Option.
• To evaluate key retrieval metrics including fluoroscopy time, tilt, adjunctive techniques, and complications.

Main Methods:

• Retrospective study of 99 Celect and 86 Option filters over 33 months.
• Data collected on fluoroscopy time, filter tilt, use of adjunctive retrieval techniques, and strut perforation.
• Statistical comparison using Fisher exact test and Mann-Whitney-Wilcoxon test.

Main Results:

• No significant difference in retrieval failure rates between Celect (3.4%) and Option (7.7%) filters.
• Option filters required significantly longer fluoroscopy times (6 min vs. 4.25 min) and more adjunctive techniques (18.3% vs. 5.4%).
• Celect filters demonstrated a significantly higher incidence of strut perforation (43% vs. 0%).

Conclusions:

• Both Celect and Option IVC filters demonstrate comparable retrieval rates.
• The Option filter necessitates increased fluoroscopy and adjunctive techniques for retrieval.
• The Celect filter is associated with a higher risk of strut perforation, a critical safety consideration.
