New York IVC Filter Attorneys

What Are IVC Filters?

IVC (inferior vena cava) filters are designed to catch blood clots in patients before they reach the lungs. The IVC or Inferior Vena Cava filter, is a very small device implanted by surgeons to stop migrating blood clots. They're used as a last resort for patients who cannot take blood thinners to reduce the risk of pulmonary embolism.

Newly inserted IVC filters can have crossed, tangled and overlapping legs & arms (also known has limbs, struts and tines). The filter does not expand and instead dangerously migrates to the renal arteries, pulmonary arteries, the right atrium, tricuspid valve, heart, kidney and liver. This requires extra surgeries known as “percutaneous” (through the vein) and “open removal” (surgery through the blood vessel).

IVC filters are spider-like metal devices implanted by catheter through the leg (femoral) or neck (jugular) veins. Filters are constrained in a capsule and pop open in the vein when released from the catheter. However, the packing and design of the filter can result in the filter’s legs and arms crossing, entangling and twisting. Alternatively, inserting doctors may do something incorrectly. Instead of filters opening in place, they travel to other organs.

Examples of IVC Filter Migrations

There are various medical journal reports of IVC filter migration to the heart, lung, kidney and liver. The FDA has also reported cases where the filter did not open and traveled to the heart.

October 2020: Denali IVC Filter FDA Adverse Event Report

MDR Report Key 10852429

  • Event Description: “It was reported that during vena cava filter deployment, the leg of the filter was allegedly twisted and the filter allegedly failed to expand. The filter was migrated into right atrium...”

September 2020: Denali Filter FDA Adverse Event Report

MDR Report Key 10893432

  • Event Description: “It was reported that during a filter placement procedure through the right femoral vein, the filter allegedly migrated to the heart and failed to deploy. It was further reported that the device was allegedly difficult to be removed from the body using a retrieval device.”

August 2018: Denali Filter FDA Adverse Event Report

MDR Report Key 7906123

  • Event Description: “It was reported that during a vena cava (ivc) filter deployment procedure, the filter legs allegedly failed to expand. It was further reported that the filter allegedly migrated toward right ventricular. Reportedly, the health care provider was not able to retrieve the filter which result in transferring the patient to the hospital for possible intervention.”

January 2017: Denali Filter FDA Adverse Event Report

MDR Report Key 6301532

  • Event Description: “It was reported that during deployment of a vena cava filter, the filter allegedly did not expand and migrated to the heart. Reportedly, multiple attempts were made to retrieve the filter but were unsuccessful.”

Retrievable IVC Filter Complications

Permanent IVC filters have been used for decades with few complications. Since 2003, retrievable/temporary IVC filters have been gaining popularity. Unbeknownst to many of the patients installed with these models, there have been many more complications with the temporary retrievable filters as compared to the permanent ones. Complications for the retrievable IVC filters include:

  • Fracture
  • Migration
  • Perforation of internal organs
  • Embedment

The purpose of using a retrievable IVC filter is so that it can be removed once it is no longer needed. The FDA issued a safety statement in May 2014 stating that patients may face an increased risk of complications with IVC filters the longer they remain inserted. The FDA advised doctors that the ideal time for removal is between 29 days and 54 days after implantation. Unfortunately, the retrieval process can cause complications such as device fracture.

Medical Malpractice or Defective Product?

Doctors known as “interventional radiologists” insert IVC filters using various wires and a catheter. From a capsule loaded by the filter manufacturer, the doctor pushes the filter to the implantation site. The covering catheter is slowly pulled back and the filter is released, hopefully to spring open and lodge into the blood vessel.

A doctor’s technique must follow the implantation instructions. Some filter deployment systems should not be twisted or retracted in certain ways. However, if the filter has tangled legs due to poor design or packaging, there is little a skilled doctor can do.

A review of medical records, x-rays, and the venogram (a live x-ray with contrast material injected into the blood vessel) helps investigating the cause of the filter failure. A law firm experienced in medical malpractice and product liability cases, and their hired independent medical experts, can do this.

IVC Filter Design Concerns

Blood vessel walls expand and constrict to keep blood moving. Because of this, IVC filters can migrate up or down due to the vessel expansion and contraction. Filters have barbs know as anchors to impede movement. These barbs face up and down (“caudal” and “cranial”). When compacted into the deployment capsule, these barbs entangle the legs.
