PRESERVE: Outcomes at 12 months

Design:
Cohort
Participants:
1429 consenting participants; 1421 received filters.
Finding:
Prespecified safety and effectiveness goals were met, with adverse events also recorded, including a death during attempted retrieval.
Main limitation
Prospective nonrandomized study, varied follow-up and many removed filters; no randomized untreated comparison or lifetime model-specific risk estimate. Original author abstract read; full paper and funding/conflicts not reviewed.

The short answer

What condition can these symptoms point to?
A clot in a leg vein or the lungs can cause symptoms. The signs alone cannot tell whether your IVC filter is involved. [9]
Which signs need a prompt doctor call?
Call a healthcare provider right away for suspected clot symptoms. A swollen tender leg or pain and shortness of breath can matter. [9]
How are the symptoms diagnosed and treated?
The care team uses your history, exam and selected tests. Ask which cause the findings support and what care is needed. [10]
What does the research say about filter symptoms?
The filter study recorded clot events and other harms. It does not let this page diagnose the cause of one person’s symptoms. [11]

The process

What happens next

  1. 01

    You answer a few questions

    About two minutes. Nothing is sent until you agree on the last step and press submit.

  2. 02

    A lawyer looks at it

    A lawyer at the firm reads your answers and checks them against the current case criteria.

  3. 03

    The firm decides and gets in touch

    If the firm takes your case, you get the terms in writing to read before you sign. You can always say no.

When it fits this case

  • These suggestions help you prepare for a claim check. They are not a firm's acceptance rules.
  • For a check, gather the filter brand/model and implant date if known.
  • Describe the harm and later care in your own words.
  • Ask a lawyer which claim, court and time limit apply.

A painful swollen leg, shortness of breath or pain when breathing may be a clot sign. Contact a healthcare provider right away. Symptoms do not identify a filter defect.

What condition can these symptoms point to?

A clot in a leg vein or the lungs can cause symptoms. The signs alone cannot tell whether your IVC filter is involved.

The filter is meant to catch clots before they reach the lungs. It does not make every later symptom a device failure. Tell the clinician that you have a filter and why it was placed, if you know.

Which signs need a prompt doctor call?

Call a healthcare provider right away for suspected clot symptoms. A swollen tender leg or pain and shortness of breath can matter.

NHLBI says symptoms are not the same for everyone; serious complications can develop without earlier warning signs. Describe what you feel, when it started and how it changed. Do not use the absence of pain as a personal safety test.

How are the symptoms diagnosed and treated?

The care team uses your history, exam and selected tests. Ask which cause the findings support and what care is needed.

The clot guide describes blood tests and imaging chosen for the patient's situation. A test for a lung clot is not automatically a finding about broken filter parts. A retrieval decision needs a separate discussion of device need and procedural risks.

What does the research say about filter symptoms?

The filter study recorded clot events and other harms. It does not let this page diagnose the cause of one person’s symptoms.

The original abstract describes 1421 implants in a prospective study at 54 sites. Many devices were removed and follow-up varied. A group result is not a symptom checklist that proves your filter caused an illness.

Who may have a claim to check?

A lawyer needs actual care findings, device records and dates. A symptom report alone does not decide legal cause or a filing limit.

For a claim conversation, separate what you noticed from what a clinician diagnosed. Ask which legal rule applies rather than treating the first painful day as a universal filing trigger. Care can proceed while legal questions are checked.

What symptom and care records should I save?

Keep dated symptom notes beside the clinical reports. Ask for the implant and follow-up records, noting which copies are missing.

As a preparation step, include the place and date of each urgent visit and any scan findings you were given. Federal access rights cover specified health records with exceptions. Do not turn an uncertain recollection into a confirmed diagnosis.
