Abstract: BackgroundProsthetic mesh implants are widely used in hernia surgery. To show long-term mesh-related complications such as shrinkage or adhesions, a precise visualization of meshes and their vicinity in vivo is important. By supplementing mesh fibers with ferro particles, magnetic resonance imaging (MRI) can help to delineate the mesh itself. This study aimed to demonstrate and quantify time-dependent mesh shrinkage in vivo by MRI.MethodsPolyvinylidenfluoride (PVDF) meshes with incorporated superparamagnetic i… Show more

“…For instance, the integration of SPIO into the base material of surgical textile implants has been shown to be a suitable method to visualize Polyvinylidene fluoride (PVDF)-based mesh-implants using MRI (86). The accurate MR assessment allowed for determining the proper operation of the implants and revealed related complications such as shrinkage or adhesions, without additional invasive surgical revision (87) (Figure 6A-C) . Beyond that, gold and silver nanoparticles were also incorporated into a biodegradable polymeric blend of poly(L-lactide)/poly/(4-hydroxybutryrate) to improve image enhancement in X-ray and near-infrared imaging of an absorbable vascular graft (88).…”

“…Being aware of approximately 8% additional shrinkage during ex vivo measurements, these results were in line with the postmortem findings. We could prove a precise visualization of the MR-visible textile implants during MRI and an accurate in vivo assessment of shrinkage (Figure 3) [12].…”

“…While cadaver studies can be generally applied, they often have limitations due to the presence of entrapped air, which can create artifacts similar to those of meshes [24]. Additionally, in order to learn more about the biological stability of this mesh, future experimental studies on live animal models seem useful and are initiated as described by other authors [11,12]. …”

“…Nevertheless, current meshes are hardly visible in magnetic resonance (MR) images besides a few exceptions such as the polyvinylidene fluoride meshes recently described [10,11,12]. The aim of this study is therefore to develop a mesh material for reconstructive surgery of female pelvic organ disorders that uses iron oxides to make it visible on MR.…”
