AngioGRAFT® cryopreserved vascular allografts are the safe choice for managing vascular reconstruction. [1]. In peripheral bypass surgery, LifeNet Health femoral and saphenous vessel allografts provide an effective clinical option. When bypassing stenosed vascular segments in the treatment of peripheral vascular disease, or in CABG procedures, acceptable native vessels are often not available. LifeNet Health cryopreserved vessels are a natural solution for peripheral bypass procedures and reconstruction. When confronting failing A/V access grafts, consider LifeNet Health allografts as an ideal natural solution for dialysis access and the replacement of infected synthetic dialysis grafts..

Despite advances in surgical technique and postoperative management, including routine administration of ASA, the incidence of early SVG occlusion after CABG surgery remains substantial in a contemporary patient population. The rate of SVG occlusion 6 months after CABG surgery observed in the RIGOR study is consistent with results from several recent studies, including the Project of Ex-vivo Vein Graft Engineering via Transfection 4 trial, which reported an overall SVG occlusion rate of 26% in 2400 patients 12 to 18 months after CABG surgery (19). Among patient- and graft-specific variables associated with SVG occlusion, bypass of small-diameter (≤1.5 mm) target vessels historically has been considered one of the strongest (17,18). In addition to this traditional risk factor, we identified shear-dependent platelet activation, measured by PFA-100 CADP CT, and ASA-insensitive TXA2 generation, measured by UTXB2, as potent novel independent risk factors for early SVG thrombosis. The combination of ...
The Dardik laboratory uses modern molecular techniques to study the diseases and therapeutics that vascular surgeons care for in their patients. As part of Yales Vascular Biology and Therapeutics program, we take advantage of our rich collaborative environment to push our field forward, focusing on basic and translational research that is relevant to our patients.. A major focus of our laboratory is to understand the healing and function of blood vessels and synthetic blood vessel substitutes and patches that are used in vascular reconstruction. We are currently trying to understand the fundamental molecular mechanisms by which vein graft adaptation and arteriovenous fistula maturation result in positive remodeling and successful adaptation to the arterial and fistula environments, yet often proceed, in the long-term, to neointimal hyperplasia and graft failure. We are focusing on the role of vascular identity in controlling the response to vascular intervention; the laboratory made the ...
We previously published that Eph-B4, a determinant of venous identity during embryonic development that persists as a venous marker, decreases expression and immunodetectable protein during vein graft adaptation in both humans and aged rats. We have extended our findings to a mouse model and have found similar results. Based on this work we hypothesize that Eph-B4 is a critical negative regulator of multiple SMC layer development.. We are currently manipulating Eph-B4 in vivo to test our hypothesis that Eph-B4 remains functional during adult life and is a regulator of vein graft identity and adaptation to the arterial environment. We are collaborating with the Sessa laboratory to test the importance of caveolin-1 binding and phosphorylation to Eph-B4 activation. We are collaborating with several other laboratories in the VBT program to assess both vein grafts as well as arteriovenous fistulae (AVF ...
BACKGROUND: Patients with peripheral artery disease have an increased risk of cardiovascular morbidity and mortality. Antiplatelet agents are widely used to reduce these complications. METHODS: This was a multicentre, double-blind, randomised placebo-controlled trial for which patients were recruited at 602 hospitals, clinics, or community practices from 33 countries across six continents. Eligible patients had a history of peripheral artery disease of the lower extremities (previous peripheral bypass surgery or angioplasty, limb or foot amputation, intermittent claudication with objective evidence of peripheral artery disease), of the carotid arteries (previous carotid artery revascularisation or asymptomatic carotid artery stenosis of at least 50%), or coronary artery disease with an ankle-brachial index of less than 0·90. After a 30-day run-in period, patients were randomly assigned (1:1:1) to receive oral rivaroxaban (2·5 mg twice a day) plus aspirin (100 mg once a day), rivaroxaban twice ...
The findings in the present study of SVG calcium are significantly different from previous IVUS reports of native-artery calcification. In the present report, only 133 (40%) of 334 SVGs contained calcium. Calcium was as common in the reference segments as at the lesion site, and calcium was more common in the vein graft wall (66%) than in the plaque (33%). In the largest previous report of native-artery lesions, 841 (73%) of 1155 target lesions contained calcium that was only superficial in 48%, only deep in 28%, and both superficial and deep in 24%. Conversely, 373 (32%) of 1155 native-artery reference segments contained calcium (P,0.0001 compared with target-lesion calcium). When present, reference-segment calcium was only superficial in 78%, only deep in 13%, and both superficial and deep in 9%. Only 44 native vessels (4%) had reference-segment calcium in the absence of target-lesion calcium.14 In the present SVG study, angiography detected calcium in only 16%, whereas in native arteries, ...

Objectives: The mechanisms of early vein graft failure after coronary artery bypass graft (CABG) surgery remains unclear. We hypothesized that insufficiency of DNA repair pathway in human vein graft is related to early graft failure.. Methods: Human internal mammary arteries (IMA) and saphenous veins (SV) samples were obtained from coronary artery bypass grafting surgery. Among 118 SV segments, there was 9% vein grafts had early grafting failure within 7 days which is determined by Multichannel-EKG-gated CT angiography (Philips Medical). In contrast, there was no early graft failure in 28 IMA grafts. Human IMA or SV segments (1 X 1 mm) were incubated in organ culture system in the absence or presence of 1% H2O2 for 24 hours with 20% O2. DNA damage was determined by 8-oxoG staining, and DNA repair pathways were investigated by MYH (DNA mismatch repair) immunohistochemical staining. Apoptotic level was evaluated by TUNEL staining and DNA gel analysis. The positive staining rate was determined by ...
We have shown for the first time to our knowledge that even in the absence of atherosclerosis, the majority of vein graft neointimal and medial cells derive from precursors that are extrinsic to the vein at the time of grafting. We have also provided the first evidence that the arterializing vein graft wall develops largely from focal expansions of progenitor cells, which originate within and outside of the vein graft at the time of implantation. Finally, we have shown that endothelial remodeling of vein grafts is accomplished by the expansion of graft-intrinsic as well as graft-extrinsic cells, and that BM-derived cells participate in this process. Importantly, these novel insights into vein graft biology derive from a murine vein graft system that we have shown to model human vein grafts, with regard to their surgical anastomoses as well as the distribution, composition and extent of neointimal hyperplasia within the grafts.12. Sources of graft-extrinsic neointimal cells in our murine model ...

Based on the finding of elevated levels of CCL3, CCL4, and CCL5, as well as their shared receptor, CCR5, during acute cardiac rejection, Gao et al evaluated the specific role of CCR5 during cardiac allograft rejection.54 Similar to CCR1, they found that CCR5 was expressed on graft infiltrating mononuclear cells. Using either in vivo neutralization studies of CCR5 or CCR5−/− recipient animals, they demonstrated that the allografts had a marked reduction in infiltrating/activated mononuclear cells (ie, cells expressing IL-2 receptor). More importantly, they demonstrated that both strategies of ablating CCR5 signaling could prolong allograft survival from 7 to 20 days. Even more profound results were seen when CsA was given to the CCR5−/− recipients (ie, permanent allograft survival without signs of leukocyte infiltration, interstitial fibrosis, or the development of TV). Interestingly, when individual ligands of CCR5 were depleted, there was no significant prolongation of allograft ...
Cardiovascular disease is the leading cause of death worldwide, accounting for 29% of all global deaths and is set to rise to 23 million deaths a year by 2030 (World Health Organisation, 2012). Arterial bypassing, both peripheral and coronary, is usually performed with autologously harvested vessels. However, the quantity available is often very limited as well as the vessels of elderly patients often suffering from thrombus, aneurysm formation or arthrosclerosis in high pressure arterial sites. The shortcomings of autografts has led to a substantial amount of research being directed towards tissue engineered vascular grafts (TEVGs) (Kakisis et al., 2005). Currently available artificial grafts for small diameter vasculature (mm) suffer from poor patency rates due to thrombosis, aneurysm formation, and a compliance mismatch, which often stems from the inherent properties of synthetic polymers. The primary goal of the research presented in this thesis was to develop a small diameter tissue engineered
