“…All of these different polymer types might have diverse medical application areas with different properties. For example, PHO-Sy with a high degradation rate can be used for vascular grafts [30,31,32,37] and PHU-Sy samples causing the least inflammatory reaction might be a good candidate for neuronal grafting since they will fasten the neuronal regeneration with much less cellular infiltration to the graft area [25]. Unoxidized PHO-Sy copolyesters can be a vehicle for chemotherapy in cancer treatment causing high fibrosis in tumor tissue as a result of the marked inflammatory response, and a low degradation rate will help the controlled release of drugs [23].…”

“…Somewhat later, fibroblasts will start to envelop the implant while giant cells, formed from macrophages, will try to phagocytose it. All these cells are carried to the implantation site by new vessels (neovascularization); therefore, neovascularization is seen on the chronic phase of inflammation and is an indicator of diffuse inflammation [24,29,32]. Although neovascularization is a major component of the inflammatory response in the foreign body reaction, it was not included in the grading system of the previous in vivo studies of polymers in the literature [23,24,29,37].…”

Biocompatibility studies of the autoxidized and unoxidized unsaturated medium-long chain length (m-lcl) co-poly-3-hydroxyalkanoates (m-lclPHAs) derived from soya oily acids have been reported. Pseudomonas oleovorans was grown on a series of mixtures of octanoic acid (OA) and soya oily acids (Sy) with weight ratios of 20:80, 28:72 and 50:50 in order to obtain unsaturated m-lcl copolyesters coded PHO-Sy-2080, PHO-Sy-2872 and PHO-Sy-5050, respectively. The PHA films were obtained by solvent cast from CHCl(3). They were all originally sticky and waxy except PHO-Sy-5050. Autoxidation of the unsaturated copolyester films was carried out on exposure to air at room temperature in order to obtain crosslinked polymers. They became a highly flexible elastomer after being autoxidized (about 40 days of autoxidation). The in vivo tissue reactions of the autoxidized PHAs were evaluated by subcutaneous implantation in rats. The rats appeared to be healthy throughout the implantation period. No symptom such as necrosis, abscess or tumorigenesis was observed in the vicinity of the implants. Retrieved materials varied in their physical appearance after 6 weeks of implantation. In vivo biocompatibility studies of the medical applications indicated that the microbial copolyesters obtained were all biocompatible and especially the PHOSy series of copolyesters had the highest biocompatibility among them.

“…Synthetic vascular grafts, including expanded poly(ethylene terephthalate) (Dacron®) or poly(tetrafluoroethylene) (ePTFE), have been largely available since the mid-1970s and represent the most widely employed vascular substitutes in the cardiovascular surgery [11]. Their large availability and ease of use have allowed an extensive application of these conduits in a wide spectrum of vascular pathologies, including aneurysms of large vessels and atherosclerosis of peripheral territories [12].…”

Aortic aneurysm (AA) and especially dissecting aneurism (DAA) represent life threatening medical conditions and vascular reconstruction surgery with the insertion of a vascular prosthetic grafts is often required to save patients life. In this paper we debate over the long term outcome of 23 patients who underwent five to eight years ago an aortic reconstruction surgery with insertion of Dacron grafts. They attended, during 2018, the emergency room of the County Emergency Hospital Pius Brinzeu of Timisoara in terms of patency complications of the prosthesis. Despite slight dilatation of the Dacron graft and of the native aorta, presence of mural thrombi and/or progress of aortic regurgitation, their evolution was satisfactory, without severe complications.

“…The porosity of commercially available polyester (Dacron) knitted vascular grafts can be reduced by coating or sealing with a novel ionic urethane, to improve their blood-proof property. The mechanical properties of coated vascular grafts have been found to be comparable with, or superior to, the pre-coated Dacron substrate [23][24][25][26][27][28][29][30][31][32][33].…”

Small diameter Polyurethane vascular graft reinforced by elastic weft-knitted tubular fabric of polyester/spandex

Small diameter vascular grafts were fabricated from pure Polyurethane (PU) as well as PU reinforced with a tubular weft-knitted fabric. The tensile properties of the reinforced composite vascular grafts were compared with that of the tubular fabric itself and the pure PU vascular grafts. The elasticity and strength of the reinforced vascular grafts were improved compared with the tubular fabric. Strength of the reinforced vascular grafts was 5-10 times of the strength of the pure PU vascular grafts. Expanding the tubular fabric to increase the inner diameter of the reinforced vascular graft reduced the graft's strength and initial modulus, but the difference was reduced as the PU content was increased. For grafts of the same inner diameter, increasing the PU content increased the thickness and strength of the graft wall, which led to a general increase in the strength and initial modulus of the composite vascular grafts.
