Retrievable Inferior Vena Cava Filters in Patients with Cancer: Complications and Retrieval Success Rate

الملخص EN

Active cancer (ACa) is strongly associated with venous thromboembolism and bleeding.

Retrievable inferior vena cava filters (RIVCF) are frequently placed in these patients when anticoagulation cannot be continued.

Objectives.

To describe the complications and retrieval rate of inferior vena cava filters in patients with ACa.

Methods.

Retrospective review of 251 consecutive patients with RIVCF in a single institution.

Results.

We included 251 patients with RIVCF with a mean age of 58.1 years and a median follow-up of 5.4 months (164 days, IQR: 34–385).

Of these patients 32% had ACa.

There were no differences in recurrence rate of DVT between patients with ACa and those without ACa (13% versus 17%, p = ns).

Also, there were no differences in major filter complications (11% ACa versus 7% no ACa, p = ns).

The filter retrieval was not different between groups (log-rank = 0.16).

Retrieval rate at 6 months was 49% in ACa patients versus 64% in patients without ACa ( p = ns).

Filter retrieval was less frequent in ACa patients with metastatic disease ( p < 0.01) or a nonsurgical indication for filter placement ( p = 0.04).

Conclusions.

No differences were noted in retrieval rate, recurrent DVT, or filter complications between the two groups.

ACa should not preclude the use of RIVCF.
