Options for revascularization of infrarenal aorta include in situ reconstruction with use of prosthetic graft or homograft
, as well as extra-anatomic bypass and endovascular stent graft [12,21-23].
The ability to remove the antigenic determinants of the cell debris holds great promise, since this would eliminate donor-specific immunoresponse in the case of homografts
and also avoid the wide use of glutaraldehyde for prevention of rejection-related reactions of xenografts.
ossicles still be used in ossiculoplasty?
Pant is soon going to restart homograft
banking facility in the department of Cardiothoracic & Vascular surgery ( CTVS).
Studies on allograft ossiculoplasty dating back to the 1970s demonstrate that allograft ossicles (notched incus homograft
) achieve excellent integration and restoration of hearing .
In Pakistan, due to non-availability of homografts
, BJVC Contegra is a good option.
There is evidence that successful skin transplants on sheep were performed in Milan in the 18th century, and it was claimed that these skin allografts (homografts
) were successful.
, freeze-dried from recently dead donors, in those days usually road-traffic accident cases, were soon replaced by synthetic grafts.
limit infection, reduce protein and electrolyte loss and alleviate pain (1).
The allogenic grafts or homografts
are taken from another individual of the same species and need a lot of preparations before being used not to induce immunologic response; similar is with bone from unhuman species.
(4) The most commonly used reconstruction materials are autografts, homografts
, and synthetic prostheses made of plastic pore, gold, (5,6) ceramic (7-15) and, most recently, titanium.
