Principles of Flap Design and Application Flashcards
he blood supply in a cutaneous flap is
random in nature and located within the subdermal plexus
T
muscle and fasciocutaneous flaps achieve comparable rates of limb salvage and functional recovery
T
important to dissect the perforator through the fascia and free up the
adventitia so that there is no venous kinking
T
Use of vessels outside
the zone of injury during free flap reconstruction leads to increased
rates of lower extremity limb salvage
T
Staged reconstructions are often required for complex defects
T
In a free flap, the arterial insufficiency represents
thrombosis of the new anastomosis until proven otherwise
T
Venous insufficiency of a flap is more common and the onset
more insidious than that ofarterial insufficiency
T
methods have improve flap survival in the case of venous congestion
release insetting sutures
the flap may be pricked with a needle serially to reduce the venous burden
Deepithelialization of a portion of the flap, or removal of the nail plate in the case of a digit with periodic application of heparin solution
Use of Hirudo medicinalis or medicinal leeches
augmenting outflow by cannulation of a vein with an angiocatheter and periodically draining the flap
The dissection extends through the skin, subcutaneous tissue, and
fascia, thus mobilizing the flap to advance into the defect in key stone flap
T
Flap types I, III, and V have the most reliable vascularity
T
prefabrication flap most commonly utilized for head and neck reconstraction
F the prelamination process
Skin and bone flaps are more tolerant of ischemia than muscle flaps
T
Vessels that are septocutaneous perforators are considered to be direct perforators
T
The supraclavicular flap is an axial flap based on
axial blood flow through the supraclavicular artery.42 It is not
considered a random flap
T
Blood flow in the supraclavicular artery is antegrade and not considered a reverse-flow flap
