Vascular grafting strategies in coronary intervention

Frontiers in Materials, 2014
With the growing need for coronary revascularizations globally, several strategies to restore blood flow to the heart have been explored. Bypassing the atherosclerotic coronary arteries with autologous grafts, synthetic prostheses and tissue-engineered ...

Endothelialization and smooth muscle cell regeneration capabilities of a bi-layered small diameter vascular graft for blood vessel reconstruction

Materials & Design, 2023
Despite the tremendous advances in the past few decades, the clinical problems associated with low mechanical strength, thrombosis, and inadequate endothelialization still have not been improved in small diameter vascular grafts.

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Transplant arteriosclerosis : an experimental study on risk factors and pathogenetic mechanisms [PDF]

, 2001
In this thesis, we focused on vascular damage inflicted after transplantation, i.e. injury of the graft vasculature as a result of an alloreactive response of the host against the graft, and everal factors in-fluencing this process.

Bioengineered Small-Diameter Vascular Xenografts as an Alternative to Autologous Vascular Grafting for Emergency Revascularization – a Preliminary Study

Journal of Cardiovascular Emergencies, 2023
Autologous vascular arterial or venous graft are not available in 10-40% of patients, due to vascular pathologies, and the utility of decellularized biological scaffolds would be a solution for those cases.

Coxiella burnetii vascular graft infection

IDCases, 2021
Q fever, a zoonotic infection caused by Coxiella burnetii, can present with a wide spectrum of clinical manifestations. The organism is typically transmitted from sheep, goats, or cattle to humans via contaminated aerosols.

Engineered vascularized bone grafts [PDF]

Proceedings of the National Academy of Sciences, 2010
Clinical protocols utilize bone marrow to seed synthetic and decellularized allogeneic bone grafts for enhancement of scaffold remodeling and fusion. Marrow-derived cytokines induce host neovascularization at the graft surface, but hypoxic conditions cause cell death at the core.
