“…In addition, the risk factor for the new graft material is difficult to prove due to the diversity of vascular graft infections. Vascularization potential, reduced thrombogenicity, and secure pseudointima growth are key parameters that could affect the successful integration and functionality of prosthetic vascular grafts [ 200 ].…”

This article presents current possibilities of using polyester-based materials in hard and soft tissue engineering, wound dressings, surgical implants, vascular reconstructive surgery, ophthalmology, and other medical applications. The review summarizes the recent literature on the key features of processing methods and potential suitable combinations of polyester-based materials with improved physicochemical and biological properties that meet the specific requirements for selected medical fields. The polyester materials used in multiresistant infection prevention, including during the COVID-19 pandemic, as well as aspects covering environmental concerns, current risks and limitations, and potential future directions are also addressed. Depending on the different features of polyester types, as well as their specific medical applications, it can be generally estimated that 25–50% polyesters are used in the medical field, while an increase of at least 20% has been achieved since the COVID-19 pandemic started. The remaining percentage is provided by other types of natural or synthetic polymers; i.e., 25% polyolefins in personal protection equipment (PPE).

“…The highest care should be taken perioperatively, as most infections are due to the surgical treatment [25]. Therefore, perioperative infection must be prevented, as the consequences for the patient are often severe [26]. A planned glove change could prevent possible unintentional contamination.…”

(1) Background: The sterile latex surgical glove is an important part of protecting both the patient and the surgical team from infections. However, mechanical stress can damage the integrity of the glove material and thus may lead to infections. (2) Method: A total of 896 gloves from 448 surgeries were tested and evaluated by the water tightening test according to EN455 and ASTM D5151-19. (3) Results: From 448 surgeries, 18.8% of the interventions showed glove damage. In vascular surgery, gloves were damaged in 20.8%, in thoracic surgery 9.1%, in laparoscopic interventions 21.7%, in the subgroup hernia surgeries (TAPP) 17.6% and in open interventions 17.6%. A total of 101 damages were found on 896 gloves; one glove could have several damages. During vascular surgery, 60% of the damages were on the subordinated hand of the surgeon, and 73.3% of the damages had a size of 1 mm. In laparoscopic procedures, the subordinated hand was also more frequently affected (61.3%) than the dominant hand; 64.5% of the damages were 1 mm in size. In the hernia surgery subgroup (TAPP), no damage was larger than 1 mm; 66.7% were in the subordinated hand area. The duration of surgery had no influence on the lesion rate. (4) Conclusion: The damage rate in low impact procedures is high and represents an underestimated problem in soft tissue surgery. The use of single gloving can therefore lead to the risk of infection. EN455 and ASTM D5151-19 does not take into consideration the risk of intraoperative lesions. Double gloving and glove change algorithms should be established.

“…However, severe trauma or insufficient blood supply caused by large-scale defects can cause serious consequences, such as claudication, sores, organ dysfunction, necrosis, or even death [ 4 , 5 , 6 ]. At present, vascular grafts are widely used clinically to prevent severe vascular injury, such as polyurethane [ 7 ], polyester [ 8 ], expanded polytetrafluoroethylene (ePTFE) [ 9 ], etc. However, the repair of vascular structures is not a single graft but a complex repair process.…”

Vascular Repair by Grafting Based on Magnetic Nanoparticles

Magnetic nanoparticles (MNPs) have attracted much attention in the past few decades because of their unique magnetic responsiveness. Especially in the diagnosis and treatment of diseases, they are mostly involved in non-invasive ways and have achieved good results. The magnetic responsiveness of MNPs is strictly controlled by the size, crystallinity, uniformity, and surface properties of the synthesized particles. In this review, we summarized the classification of MNPs and their application in vascular repair. MNPs mainly use their unique magnetic properties to participate in vascular repair, including magnetic stimulation, magnetic drive, magnetic resonance imaging, magnetic hyperthermia, magnetic assembly scaffolds, and magnetic targeted drug delivery, which can significantly affect scaffold performance, cell behavior, factor secretion, drug release, etc. Although there are still challenges in the large-scale clinical application of MNPs, its good non-invasive way to participate in vascular repair and the establishment of a continuous detection process is still the future development direction.
