D. Lenen et al., ANATOMICAL BASIS OF A FASCIOCUTANEOUS PEDICLE FLAP BASED ON THE INFERO-LATERAL COLLATERAL ARTERY OF THE LEG, Surgical and radiologic anatomy, 16(1), 1994, pp. 3-9
An anatomical study of 30 cases has been performed on the vascularisat
ion of the distal third of the antero-lateral compartment of the leg,
with particular reference to the relations of the infero-lateral colla
teral artery of the anterior tibial artery, the perforating branch of
the peroneal artery, and the antero-lateral malleolar artery. A fascio
-cutaneous pedicle flap based on the infero-lateral collateral artery
is described noting that the superior, anterior, and posterior limits
are similar to those of the lateral supramalleolar flap of Masquelet.
The interior limit of this new flap is 15 mm distal to the site of eme
rgence of the perforating branch of the peroneal artery. The advantage
s of this flap are; a large surface area for cover. antegrade vascular
isation. and no significant vascular sacrifice. The distal half of the
calf can be covered both medially and posteriorly as well as the prox
imal half of the dorsum of the foot, the medial and lateral arch areas
, the perimalleolar region. and the region behind the Achilles tendon.
The flap requires the presence of the infero-lateral collateral arter
y of the tibialis anterior which can be confirmed either peroperativel
y or preoperatively by angiography.
