Tensor Fasciae Latae Perforator Flap: Minimizing Donor-Site Morbidity in the Treatment of Trochanteric Pressure Sores

Abstract

This flap is an alternative to myocutaneous flaps, as it preserves local musculature without functional sequelae in patients who walk. It also preserves the local musculature in the event of recurrence, as is usually seen in paralytic patients with pressure sores.

Significance of anatomical variations of the lateral circumflex femoral artery for the tensor fasciae latae flapping

“…Knowledge of the characteristics of the vascular stalk of the TFL muscle, and especially the anatomical variances, has an extraordinary significance in planning and successful using of the TFL flap, transpositional ones, as well as free flaps [1,10,15,18]. Transposistional TFL flap sufrace is larger than the free flap surface, which is due to the vascularisation of the TFL muscle both by the LCFA and the superior gluteal artery as an accessory vascular branch [8,19,32,39].…”

“…It inclines between the anterior and the posterior division of the femoral nerve, posterior to the sartorius and the rectus femoris muscles, then ends by dividing into the ascending, transverse and descending branches. The ascending branch runs under the TFL muscle and anastomosis with the superior gluteal and the deep circumflex iliac arteries and supplies the greater trochanter, the head and the neck of femur [13,15,28,29,31]. Some authors describe that LCFA gives only the ascending and the descending branch, while the transverse one is the branch of the ascending one [17,26].…”

“…The blood supply of the TFL flap has been described as being through the lateral circumflex artery (LCFA) of the profunda femoris artery (PFA) [13,15,28]. LCFA is routinely a lateral branch of PFA, near the root.…”

Reconstruções pelveperineais com uso de retalhos cutâneos baseados em vasos perfurantes: experiência clínica com 22 casos

“…The flaps were planned and the isolation and dissection of the perforators were based on the anatomic repairs described 6 . In sacral ulcers (15 cases, 62.2%), a superior gluteal artery perforator flap was used 7 ; ischial ulcers (3 cases, 13.6%) were repaired using an inferior gluteal artery perforator flap 8 with V-Y advancement flaps; and trochanteric ulcers (2 cases, 9.1%) were treated with a skin flap based on the transverse branch of the lateral femoral circumflex artery 9 . The gluteofemoral fasciocutaneous flap 10 based on the descending branch of the inferior gluteal artery was the choice for reconstruction in a patient with a perineal injury associated with Fournier syndrome and in 1 patient after resection of perineal hidradenitis ( Table 1).…”
