In a skin graft transfer the work 'take' of graft refers to
|A||Healing of graft|
|B||Vascularization of graft|
|C||Dense attachment of graft to surrounding tissue|
|D||Epithelial in growth in the margins|
a. Skin grafts are mainstays for reconstruction of superficial defects or adjuncts to more complex reconstructions.
b. The type of skin graft is based on the thickness of the graft taken.
c. A split-thicknessgraftrequires that a portion of the dermis be taken along with the epidermis.
d. A full-thickness graft is one in which the full portion of the dermis is taken with the superficial epidermis .
e. The grafts will survive transfer based on a defined sequence of events that culminates in vascular independence. These events are
i. Serum imbibition—direct absorption of nutrients from recipient capillary beds that generally takes place in the first 24 hours;
ii. Inosculation—the connecting of donor and recipient vessels that typically begins in the 24- to 72-hour period; and
iii. Angiogenesis—vascular ingrowth of vessels from the recipient bed into the graft that starts after 72 hours.
f. Split-thickness skin grafts are taken from sites depending on the thickness, color, and quality of skin needed.
g. Full-thickness grafts are taken from areas in which primary closure can be accomplished, such as the groin or within redundant skin folds.
h. Skin grafts can be fixed in place with compressive dressings to prevent problems with shear and fluid collection.
