Abstract:

Objective

To retrospectively analyze the clinical experience and skills of LOOP technique for difficult inferior vena cava (IVC) filter retrievals.

Methods

A retrospective analysis was conducted in 27 patients with difficulty in retrieving IVC filters by LOOP technique from January 2015 to June 2020 in the First People's Hospital of Zhaoqing and the Third Affiliated Hospital of Sun Yat-sen University.

Results

The filter was successfully removed in 17 patients, completely with the success rate was of 63.0%. The average operation time was 96 minutes. The filter was taken out in one piece, the IVC angiography was unobstructed and there was no contrast exosmosis. Of the 10 patients who failed to remove the filter, there were no surgerysurgical-related complications and they need lifelong anticoagulation.27 patients were discharged from hospital smoothly after operation. During follow-up period, no patients developed symptomatic pulmonary embolism.

Conclusions

The LOOP technique applied to cases with difficult recovery of IVC filters has high safety, simple operation, and clinical effectiveness, and it is worthy of clinical promotion
