Allo – Same species
Auto – Same person
Xeno – Animal (different species)
An autologous transplant uses a person's own stem cells.
... In a reduced-intensity allogeneic transplant, doctors suppress the
recipient's immune system enough so the donor stem cells can take root, or
“engraft,” there.
An autograft is a bone or tissue that is taken from a
part of a person’s own body and transplanted into another. Often, surgeons will
use a person’s own hamstring tendon to repair a damaged anterior cruciate
ligament. Similarly, an autograft bone may be transplanted from a person’s hip
to aide in a spinal fusion. Patients who undergo autograft procedures may
experience increased postoperative pain from the second surgical (autograft)
site. They may also require longer periods of rehabilitation.
The use of allograft is advantageous because there is no
second procedure required to remove and transfer a portion of the patient’s
native bone or tissue. Surgical time may be minimized, postoperative discomfort
reduced and patients may be back to normal activities more quickly.
No Guesswork. With autograft, graft sizing is a variable
that must be managed adding to the time and potential complexity of each
procedure. Allografts are measured to match specifications requested by a
surgeon for each case; therefore, graft size is known at the time of surgery
Patients that undergo procedures using allograft may experience reduced
surgical time, which may result in reduced operating room costs.
Xenograft: The
transplant of an organ, tissue, or cells to an individual of another species.
Manufactured
Mechanical Valve
These valves are made of strong durable materials. They
are the most long-lasting type of replacement valve, and most of these
manufactured valves will last throughout the remainder of the patients’
lifetime. But there is a catch though!
Patients who receive a manufactured valve will nearly
always require a blood thinning medication throughout the remainder of their
lives. The blood thinner will keep clots from forming, which is critical for
the person with a mechanical valve because clots can lodge in the valve flaps
or hinges and cause a malfunction. Clots can also break off and form into an
embolism (traveling clot), which may move through the bloodstream and lodge
into a vessel where it may eventually lead to problems like heart attack or
stroke.
Donor Valve Implantation
A human donor valve is the least common choice and it’s
most often used for someone who is suffering from an illness that affects the
valve, such as infective endocarditis. A donor valve can be expected to last
10-20 years.
Tissue Valve (sometimes called ‘bioprosthetic’ valves)
Tissue valves are created from animal donors’ valves or
other animal tissue that's strong and flexible. Tissue valves can last 10-20
years, and usually don't require the long-term use of medication. For a young
person with a tissue valve replacement, the need for additional surgery or
another valve replacement later in life is highly likely.
