What is a Hemashield patch?
Hemashield Finesse Ultra-Thin Knitted Cardiovascular Patch. Indicated for cardiac and vascular patch grafting. The fabric is recommended for use in patients requiring systemic heparinization prior to, or during, surgery.
Why is Dacron used in surgery?
A polyester graft is used to replace the diseased aortic tissue. The polyester grafts (such as Dacron) are an excellent example of successful substitution of a synthetic material within the human body. Dacron is so completely compatible with the body that rejection and calcification do not occur.
Is a Hemashield graft synthetic?
Considering its easy handling and wide flexibility in length adjustment, we suggest that the Hemashield vascular graft is one of the best prosthetic materials for MHV reconstruction.
What is a patch graft?
Medical Definition of patch graft : a graft of living or synthetic material used to repair a defect in a blood vessel.
What is a vascular patch?
Vascular-Patch. Vascular-Patch is produced from polyester-urethane and is characterized by an excellent biocompatibility and proven long-term mechanical stability. The elastic material ensures minimum suture hole bleeding and a compliance which is unmatched by any other synthetic patch.
How long do Dacron grafts last?
The function of the aortic valve implanted inside a tubular Dacron graft remains normal at 15 years in most patients after this type of aortic valve–sparing operation.
How long does a Hemashield graft last?
The patency rates of the Hemashield-interposed MHV conduits were 88.8% at 3 months, 71.6% at 12 months, and 57.3% at 18 months (Figure 4), and the patency rates in the Hemashield group were found to be superior to those in the Gore-Tex group (p=0.048).
What is scleral patch graft?
Scleral grafting with overlying conjunctival or amniotic membrane graft is an effective and simple measure for preserving globe integrity both structurally and functionally.

What is life expectancy after aortic root replacement?
Conclusions: Based on current evidence the calculated average autograft-related reoperation-free life expectancy is 16 years. The combination of meta-analysis and microsimulation provides a promising and powerful tool for estimating long-term outcome after aortic valve replacement.
