Bases anatomicas y quirúrgicas del colgajo de perforante axilar

and inferior external quadrants; 12 of them, rice from axillar artery as direct branches; 6 of them, rice from collateral arteries: 4 from lateral thoracic artery, and 2 from thoracodorsal artery. Using doppler flowmetry in 30 axilas from volunteer people, we found more arteries at internal-inferior and external-superior localizations Finally, in 7 cases operated on with reconstructive surgery, the dissections rea - ched 3-4 cm length; as a result, we could not observe the origin of the vessels. Conclusions . The CPA is very useful in severe scar sequels due to burns in the chest and upper limb. The dome axillary anatomy respects it to a great extent in these patients, functioning as a donor site present in 90% of cases as an advantage over other flaps. Although it is not necessary to dissect to the origin of the perforator, knowing its origin provides greater security since the burned tissue does not respect normal anatomy. Our study provides greater precision in the marking and finding of perforators to accelerate their dissection, obtain a longer pedicle to reach distant areas and replace a larger tissue surface.
