Inferior Vena Cava Retrievable Filters: Spanish Register

Study Overview
=================
Brief Summary
-----------------
Spanish registry of retrievable vena cava filters. This registry is sponsored by the Spanish Society of Vascular and Interventional Radiology (SERVEI) and conducted by the Research Group GITMI (Group of Research in Minimally Invasive Techniques) of the University of Zaragoza (Spain). A software tool hosted on the official website of SERVEI and the journal Intervencionismo will be used for data collection a(https://estudios.watsoncme.com).

Detailed Description
-----------------
This is an prospective observational study of patients that have been implanted a inferior vena cava filter with intention to be retrieved. Patients are recruited when the filter is implanted, and the investigators observe when is it finally retrieved (dwell time), if retrieval is possible or not, and if there is any complication at the retrieval of the filter.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Success of retrieval | The primary outcome of this study is to verify if the filter can be retrieved on the scheduled day of retrieval (yes/no). | 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dwell time | Final dwell time of the filter (number of days from implantation to retrieval). It will be compared to the expected dwell time at the time of implantation. | 12 months | 
| Complications in retrieval | Difficulties in retrieval and complications at the time of retrieval will be specifically recorded. | 12 months | 
| Overall adverse events | Registry of adverse events from filter implantation until retrieval. | 12 months |
