Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Filtration

Filtration

Filtration is a physical separation process that involves passing a suspension through a porous medium to separate solids from fluids. During filtration, solids collect on the porous medium while liquids, also collectively known as the filtrate, pass through. The filtration medium is selected based on the filtration purpose, quantity, and nature of the precipitate. The general criteria for a suitable filtering medium are that it is inert, mechanically strong, nonabsorbent toward dissolved...

Area of Science:

Biomaterials Science
Vascular Surgery
Medical Device Engineering

Background:

Inferior vena cava filters (IVCFs) are used to prevent pulmonary embolism but carry risks like migration, obstruction, and retrieval complications.
Retrievable IVCFs can lead to adverse events during removal, including adherence to the venous wall and procedural failure, with reported complication rates varying by filter type.
Lifelong anticoagulant therapy is often required with traditional IVCFs.

Purpose of the Study:

To review advancements in biodegradable (absorbable) IVCFs.
To highlight the potential of biodegradable filters as a safer alternative to traditional IVCFs.

Main Methods:

Literature review of preclinical and clinical trial data on biodegradable filters.
Analysis of adverse event rates associated with retrievable IVCF retrieval procedures.

Main Results:

Biodegradable filters have demonstrated proven biocompatibility and therapeutic efficacy in preclinical and clinical studies.
Traditional retrievable IVCF retrieval can have complication rates ranging from 0% to 27% depending on the filter model and retrieval technique.
Specific retrieval challenges include filter adherence to the venous wall and patient-related issues like pain.

Conclusions:

Biodegradable filters represent a significant advancement, offering both safety and efficacy.
These filters show considerable potential for widespread clinical application in preventing pulmonary embolism.
Further research and development in biodegradable filter technology are warranted.
