“…The optimal graft type for lower extremity bypass continues to be an area of discussion, with autologous generally being the preferred choice when available, and bovine carotid, an acceptable substitute, that does not markedly compromise limb salvage or patency in urgent situations where minimal dissection and surgical time are imperative. [24][25][26][27] Antiplatelet therapy with femoropopliteal grafting is another point of consideration in this case; no standard protocol is currently accepted. 24,28 Approximately 10% of the femoropopliteal and femorodistal grafts fail within 1 month postoperatively while most of the grafts (80%) fail between 1 month and 2 years, requiring surgical reintervention.…”

Acute Femoropopliteal Bypass Graft Occlusion After Knee Manipulation Under Anesthesia: A Case Report and Review of Current Literature

2022

Bilateral tibiofemoral knee dislocations are a relatively rare injury, and there is a scarcity of literature on its appropriate evaluation and treatment. Even less knee dislocations with concomitant popliteal artery injury have been described. Postoperative graft occlusion accounts for approximately half of the overall complication rate, occurring in up to 18% of the patients undergoing femoropopliteal bypass grafting. Furthermore, anticoagulation and antiplatelet therapy after graft placement is a point of contention. Here, we describe a case of a knee dislocation with associated popliteal artery transection treated initially with successful knee-spanning external fixation and arterial grafting, respectively. At 6 weeks after injury, the patient underwent external fixation removal and closed manipulation of the knee for arthrofibrosis. After manipulation, yet still under anesthesia, distal pulses were acutely diminished and subsequent CTA demonstrated femoropopliteal graft thrombosis. This case demonstrates successful recognition, thrombectomy, and restoration of arterial blood flow, which has since been maintained. Written consent by the patient involved in this case report was obtained.T ibiofemoral knee dislocations (KDs) are rare, so recognition and treatment of associated arterial injury can be difficult. [1][2][3][4] In addition, no gold standard for treating these concomitant orthopaedic and arterial injuries has been defined. 5 KDs are reported as less than 0.02% of all orthopaedic injuries. 6 Although there have been reported cases of bilateral KDs, there have been even fewer KDs with a concomitant popliteal artery injury. [1][2][3][4] In 2018, Moura et al 6 described a case of bilateral KDs with associated bilateral popliteal artery injuries, which was the first reported case at the time. A case series of two patients who required popliteal artery grafts after unilateral KDs reported limb survival; in their literature review, they found both a lower proportion of concomitant vascular injury with KDs and an even lower proportion that undergo surgical treatment than previously reported. 7 Zachary W.

“…Beyond hemodialysis, xenografts have also been utilized for vascular repair with satisfactory patency and long-term performance, 67,68 even when compared with autologous grafts. 69,70 Not all vascular applications of xenograft ECM have shown desirable efficacy, however. While some successes have been documented, 71,72 implementation of xenografts to repair cardiac defects and damage have produced higher rates of reintervention and failure in both neonatal/pediatric populations, [73][74][75] as well as adults.…”

Cardiovascular defects, injuries, and degenerative diseases often require surgical intervention and the use of implantable replacement material and conduits. Traditional vascular grafts made of synthetic polymers, animal and cadaveric tissues, or autologous vasculature have been utilized for almost a century with well-characterized outcomes, leaving areas of unmet need for the patients in terms of durability and long-term patency, susceptibility to infection, immunogenicity associated with the risk of rejection, and inflammation and mechanical failure. Research to address these limitations is exploring avenues as diverse as gene therapy, cell therapy, cell reprogramming, and bioengineering of human tissue and replacement organs. Tissue-engineered vascular conduits, either with viable autologous cells or decellularized, are the forefront of technology in cardiovascular reconstruction and offer many benefits over traditional graft materials, particularly in the potential for the implanted material to be adopted and remodeled into host tissue and thus offer safer, more durable performance. This review discusses the key advances and future directions in the field of surgical vascular repair, replacement, and reconstruction, with a focus on the challenges and expected benefits of bioengineering human tissues and blood vessels.

“…Allograft and xenograft vessels prepared by cryopreservation or decellularization to reduce immunogenicity have been used as an alternative to autologous vessels but generally suffer from lower patency. This has attributed to increased thrombogenicity, host immune response, and increased calcification [13][14][15][16]. Synthetic grafts composed of expanded polytetrafluoroethylene (ePTFE) and poly-ethyleneterephthalate (Dacron) have been used clinically since the 1950s for the replacement of medium to large diameter vessels.…”

Due to the prevalence of cardiovascular diseases, there is a large need for small diameter vascular grafts that cannot be fulfilled using autologous vessels. Although medium to large diameter synthetic vessels are in use, no suitable small diameter vascular graft has been developed due to the unique dynamic environment that exists in small vessels. To achieve long term patency, a successful tissue engineered vascular graft would need to closely match the mechanical properties of native tissue, be non-thrombotic and non-immunogenic, and elicit the proper healing response and undergo remodeling to incorporate into the native vasculature. Electrospinning presents a promising approach to the development of a suitable tissue engineered vascular graft. This review provides a comprehensive overview of the different polymers, techniques, and functionalization approaches that have been used to develop an electrospun tissue engineered vascular graft.
