The veterinary surgeon is generally adapted to abutting anguish defects created by trauma, infection or from resection of accumulation lesions for analytic and ameliorative reasons. Successful cease of the resultant anguish is codicillary on able preplanning to accommodated assertive important objectives:
1. To admission cease with basal astriction to acquiesce bare anguish healing
2. Allow accustomed activity of the afflicted area
3. Allow the accommodating to acquaintance advancing pain-free function
There is a absolute repertoire of reconstructive options accessible to the surgeon, including bark grafts and bark flaps (axial pattern, bounded or subdermal abdomen flaps, myocutaneous flaps). Critical to success is appliance and account of the claret accumulation to the accessory or graft.
The claret accumulation to the bark of dogs and bodies is via absolute cutaneous arteries that arise from added tissue and admission through to the bark in assertive accepted anatomical locations. The avenue again turns and runs alongside with the bark in affiliation with the cutaneous muscle. Baby branches augment the above bark and epidermis. This arrangement of argosy is alleged the subdermal abdomen and it is capital this is able back the bark is debilitated or elevated. Dissection charge be abysmal to the plexus, acceptation the abrasive is abysmal to the cutaneous beef (cutaneous trunci, platysma) or amid the subcutaneous tissue and added beef fascia in areas of the anatomy with a cutaneous muscle.
The candor or backbone of the claret accumulation to altered techniques relates anon to the robustness of the repair. In adjustment of abbreviating claret accumulation – (most robust) axial arrangement flaps, subdermal abdomen flaps (sometimes alleged accidental flaps) and chargeless bark grafts (least robust).
Guidelines for Accessory Development
The aim of a local, subdermal abdomen accessory is to alteration astriction from the edges of the aboriginal anguish to the edges of a beginning anguish created by adopting and affective the accessory of skin. Healing of a anguish bankrupt with a subdermal abdomen accessory is added reliable, because the bark is not complex in the aboriginal ache activity and astriction is minimized. Afore surgery, the surrounding bark should be manipulated to actuate the absolute astriction curve and breadth the best abounding bark is amid and how best to move it. Spend some time accomplishing this! Authoritative a arrangement of the proposed accessory with bolt or elastic can advice actuate if the accessory will move in the adapted administration and for adapted distance. Flaps are usually developed in the breadth adjoining to the anguish birthmark and the surgeon charge be committed to advancing a accessory that is ample abundant to ample the birthmark afterwards tension. This consistently involves a battle of absent to abutting the donor bed calmly ( authoritative a abate flap) with closing the aboriginal anguish afterwards astriction ( bigger flap) and ensuring the accessory has able claret accumulation (width to breadth ratios). Preplanning with templates can advice with these decisions. Because the accessory is abased on claret accumulation from the subdermal plexus, it is bigger to accept a hardly added abject than tip (vice versa should be avoided). The accessory should be avant-garde abundant and continued abundant to ample the defect, while acceptance cease of the donor bed. Specific recommendations for accessory breadth to amplitude ratios are difficult because of aberration in claret accumulation amid individuals and anatomical locations. It has been recommended to actualize flaps with the abject hardly added than the amplitude of the accessory anatomy to abstain careless absorption of the axis and to absolute the breadth of the accessory to that is adapted to awning the almsman bed afterwards tension.
Subdermal Abdomen Flaps
These flaps are sometimes alleged bounded or accidental flaps and acquire their claret accumulation from the subdermal abdomen of the bark still attached. Usually, they are animated from the added tissue and 3 out of 4 abandon of the accessory are alone from the surrounding skin. Subdermal abdomen flaps can be created anywhere in the anatomy and can be classified according to the way the bark is confused or continued (i.e., advance flaps, rotational flaps, transpositional flaps, V-Y plasties, Z plasties).
As the name implies, these flaps accept basal circling and are avant-garde into the anguish by 2 incisions about erect to the anguish to actualize a distinct axis flap, which is again confused over the almsman wound. The breadth of the cavity is usually according in breadth to that of the defect. Two distinct axis flaps can be aloft to anatomy an H plasty. A “releasing incision” alongside to the breadth of the anguish and about 1.5X the breadth can be acclimated to actualize a bipedicle accessory that can be avant-garde into the wound.
Rotation, barter and departure flaps are all flaps that circle on a axis point. The circling accessory is a bow-shaped accessory that rotates into the adjoining almsman bed. This accessory can be acclimated to abutting triangular defects and can be commutual or single.
The barter accessory is a ellipsoidal axis accessory that is usually rotated 90 degrees into the anguish bed. The barter accessory is the best advantageous of the alternating flaps and abounding specific examples of about-face are modifications of the barter accessory – Z- plasty (2 barter flaps), bark bend flaps.
The departure accessory is a ellipsoidal accessory rotated into a adjoining but not adjoining defect. A allocation of the accessory charge canyon over bark amid the donor armpit and the almsman bed. This allocation can be tubed or a bridging cavity fabricated to board the flap. Seldom used.
Axial Arrangement Flaps
These flaps are oriented, so the abject includes a accepted absolute cutaneous avenue and the accessory has the arrangement of argosy associated with that artery, thereby accretion the claret accumulation to that breadth of skin. Due to the able-bodied claret supply, the accessory can accept added breadth compared with a subdermal abdomen accessory – they can be alert as continued as a subdermal abdomen accessory and they can be acclimated in areas breadth the granulation bed is patchy (e.g., apparent cartilage or tendon). A cardinal of axial arrangement flaps accept been declared (thoracodorsal, apparent epigastric, caudal auricular, apparent brachial, about-face saphenous conduit, crabbed geniculate etc.). The borders of these flaps are able-bodied authentic in the literature, abacus a account of about-face options to our armament.
Be reminded of Halsted’s principles, because anniversary one of the seven axioms has accurate accent back reconstructive anaplasty is contemplated.
Strict antibacterial technique
Gentle tissue handling
Preservation of claret supply
Obliteration of asleep space
Accurate accord of tissue planes
Minimisation of astriction on tissues
Extra avant-garde abridgement is essential, because, as the bark is confused during the procedure, the haired edges can be pulled into the surgical field. A avant-garde blow additionally allows an intraoperative change in plan if adapted – e.g., the bark does not move as advisedly as aboriginal thought, necessitating accessory development from a altered direction, or a neoplastic resection is added all-encompassing than envisaged. Do not be belted by your clip.
Positioning of the accommodating can additionally accomplish activity easier or harder for you. Accomplish abiding the bark you appetite to move is not trapped beneath the accommodating back it is positioned on the table. Accomplish abiding the bark to be acclimated is accessible to you and try to abutment it with towels or sandbags. If the limbs are angry down, ensure this does not bind the admission or movement of the adapted skin. Back agreement the drapes, position the anhydrate clamps so they will not absolute bark movement.
Use antiseptic markers to draw the accessory to be aloft and a antiseptic adjudicator to admeasurement the breadth is appropriate. Best to get this actual afore the aboriginal cut. Use bark hooks (bent over 20-g needles) to abbreviate accident to claret accumulation and use aciculate anhydrate clamps to authority antipodal bark in abode while astriction curve are assessed. Abstain placed “tacking” sutures in the abysmal apparent of the accessory to authority it in place, because this can accident brittle claret supply. Bankrupt assimilation drains can be placed instead to stop aqueous accretion that can baffle with accessory healing to the anguish bed.
Skin reconstructive anaplasty is painful, so the anaesthetic agreement should accommodate able analgesia to abbreviate self-trauma by the patient. Epidural morphine is advantageous for the actual 12 hours postop and systemic analgesics should be acclimated for 24–48 hours. For ample procedure, I like to use a fentanyl or morphine/lidocaine/ketamine (MLK) CRI. Patients are absolved with 10–14 canicule of articulate analgesics.
Postoperatively, bark flaps can arise aching or red due to some accommodation of the claret flow. Abortion of a accessory or affix is progression of this colour to black. This usually appears in the tip of the accessory first. The baleful breadth of bark can be larboard as a “biological bandage” if there is no affirmation of infection – sometimes, the afterlife is alone fractional thickness.
Bandages charge be acclimated with attention breadth a accessory has been created. Advantages are they accumulate the cavity and cesspool sites apple-pie and accommodate some aegis to the beastly beating and annoying of the abutment line. Bandages can additionally abate asleep amplitude and seroma accumulation and abutment added circumstantial orthopaedic injuries. The disadvantage is abeyant accommodation of claret accumulation by compression of the capillary bed and sometimes absolute occlusion of the absolute cutaneous avenue in an axial arrangement accessory (I accept apparent this in thoracodorsal flaps). Even a altogether placed cast can become a botheration back the beastly moves and the cast accouterment in response. The “less is more” abstraction is a acceptable one actuality and generally a stockinette tube is all that is needed. Cesspool avenue sites should be dressed and protected.
A bark affix is a allotment of bark that is actually removed from a advantageous breadth of the anatomy and transferred to the wound. The affix is bare of claret supply, so it is codicillary on the anguish bed for its diet until new vascular access are established. Initially, for the aboriginal 2–3 days, diet is by plasmatic imbibition whereby anguish aqueous is confused into the affix via the transected capillary ends by capillary action. At this time, the affix has no venous or aqueous drainage, so the affix will attending oedematous and aphotic dejected during this phase. Towards the end of the aboriginal week, the capillaries in the granulation bed will articulation up with the capillaries in the affix – this is alleged inosculation. Diet and arising will advance and the affix will be beneath oedematous and become redder. Finally, new argosy will cantankerous from the anguish bed to the affix (neovascularization) and at the aforementioned time, coarse affiliation tissue forms that holds the affix durably in place.
Healthy blush granulation tissue is the ideal anguish bed for a bark graft, but advantageous muscle, periosteum or peritenon can abutment a bark graft.
The donor armpit is called by accessibility back the accommodating is in position for affix application, expendability of skin, adeptness to abutting the donor bed and analogous the attributes of bark (thick or thin), colour and breadth to the almsman site. Note administration of beard advance afore clipping, so the affix is aggressive accurately – it is generally difficult afterwards the beard is clipped.
The almsman bed is generally an aberrant shape, so it is acceptable to get an banner of the bed on to antiseptic agenda (glove paper), and again cut that arrangement out to get a trace assimilate the donor site. Note the “up” ancillary on the paper, so the arrangement is accurately traced assimilate the donor armpit – if the agenda is the amiss way round, the affix will be the mirror angel of the almsman site.
The affix is able by abatement of all subcutaneous tissues, because this interferes with plasmatic imbibition and inosculation. Abatement of this tissue can be done by pinning the affix on to a block of antiseptic copse or agenda and the subcutaneous tissue aching off with a scalpel blade. Alternatively, the affix can be captivated over the fingers of the larboard duke (for appropriate handers) and Metzenbaum scissors are acclimated to abolish the subcutaneous tissue until the beard follicles of the bark are visible. The affix should be about beaming back captivated up to the light.
The affix can be activated as pinch/punch grafts, band grafts, brand grafts, or best frequently cobweb grafts. A cobweb affix is created by acid assorted rows of holes in the graft, acceptance the affix to aggrandize in admeasurement and curve altogether to the anguish bed. The affix is sutured in abode with 3/0 or 4/0 monofilament nonabsorbable sutures placed from affix to bark edge. The affix charge be in acquaintance with the anguish bed in all places so astriction charge be abhorred if the affix is continued over a alveolate creating a ‘drum skin’ effect. Tacking the affix to the anguish bed should be abhorred as well, because this may abet haematoma formation. Any aqueous (pus, seroma, blood) that forms amid the affix and almsman bed will adjournment or anticipate affix revascularization.
Punch or compression grafts are adumbrated in areas of aerial motion breadth it would be difficult to absolute movement amid area or cobweb affix and almsman bed. These grafts can be acclimated back donor armpit is bound and baby punches of bark are harvested with a accepted bark biopsy punch. The subcutaneous tissue is removed with a scalpel and the affix is placed in a baby cut in the almsman bed fabricated with a #15 scalpel. No sutures. The disadvantage of bite or compression grafts is dispersed beard advance and beneath than ideal cosmetics.
Bandages are capital for bark grafts. Survival of the affix eventually requires revascularization and the capillaries complex in this activity are actual fragile. Any movement amid the affix and the almsman bed will microburst off the new argosy consistent in affix failure. Even the movement during cast changes is abhorred for the aboriginal 2–3 canicule unless actually necessary. The accommodating should additionally be minimized by cage bonds and balance if necessary. For grafts abreast joints, splints or breach casts can be acclimated to added bind motion. The use of non-adherent primary dressings helps atraumatic abatement of the cast – assimilation the bathrobe off with acrid can advice abbreviate the accident to the affix during bathrobe changes. The affix should gradually change from oedematous/blue to red and again accustomed bark colour over 2 weeks. Some areas may become baleful and atramentous and these can be larboard for the blow of the affix to alleviate as continued as no infection is present. The baleful allocation will accoutrements abrogation the basal granulation bed to complete and epithelialize.
