Summary. Flaps represent segments of the skin and subcutaneous tissue, fascia, muscles or bones, with their own vascular net on a particular vascular stalk. For a successful usage of a flap, it is necessary to know its vascular net, as well as the areas supplied by its vascular stalk. The most frequently used flap for covering defects in the groin, lower part of the abdomen, trochanter, gluteal and ischiadicus region is the tensor fasciae latae. The muscle is short and meaty only in its upper third, after which it descends as a broad tough strip entering the iliotibial tract of the iliotibial fascia latae Maissiat tract. The muscle is vascularized by the lateral circumflex femoral artery, that is, by its ascending branch which, as a single dominant branch, enters the muscle through its medial side. The lateral circumflex femoral artery is the lateral branch of the deep femoral artery which is the largest lateral branch of the femoral artery. The dominant vascular stalk enters deep structures 8-10 cm beneath the anterior superior iliac spine. The knowledge of the vascular net and vascular stalk characteristics of the tensor fasciae latae has an exceptional significance in plastic and reconstructive surgery as it can help prevent flap necrosis during its usage for defect reconstruction and covering. Therefore, the knowledge of the lateral circumflex femoral artery origin and its branches is of a great importance in successful planning and clinical application of this flap.
Key words: Flap, tensor fasciae latae, vascularization
ANALIZA VASKULARNE PETELJKE REŽNJA M. TENSOR FASCIAE LATAE
Kratak sadržaj: Režnjevi predstavljaju segmente kože i potkožnog tkiva, fascije, mišića ili kosti, koji imaju svoju vaskularnu mrežu na određenoj vaskularnoj peteljci. Da bi se režanj uspješno koristio neophodno je poznavanje njegove vaskularne mreže, kao i površine koju vaskularizuje vaskularna peteljka. Režanj koji se najčešće koristi u prepokrivanju defekata u preponi, donjoj polovini trbuha, trohanternoj, glutealnoj i ishijadičnoj regiji je mišić zatezač fascije buta (m.tensor fasciae latae). Mišić je kratak i mesnat samo u gornjoj trećini, da bi se dalje nastavio jakom žilastom trakom koja ulazi u sastav bedreno-golenjačnog snopa butne fascije (tractus iliotibialis fasciae latae Maissiati). Vaskularizacija mišića potiče od spoljašnje polukružne butne arterije (a.circumfexa femoris lateralis), odnosno njene ascedentne grane (ramus ascendens), koja kao pojedinačno dominantna grana ulazi kroz medijalnu stranu u mišić. Spoljašnja polukružna butna arterija (a.circumfexa femoris lateralis) je bočna grana duboke butne arterije (a.profunda femoris), koja je najveća bočna grana butne arterije (a.femoralis). Dominantna vaskularna peteljka ulazi u duboke strukture 8-10 cm ispod prednje gornje bedrene bodlje.
Poznavanje vaskularne mreže i karakteristika vaskularne peteljke režnja m.TFL ima izuzetan značaj u plastičnoj i rekonstruktivnoj hirurgiji, a u cilju prevencije nekroze režnja prilikom njegovog korišćenja za rekonstrukcije i prepokrivanje defekata. Stoga je, poznavanje načina nastanka a.CFL i njenih grana, od velikog značaja za uspješno planiranje i kliničku primjenu ovog režnja.
