Free-flap breast reconstruction is a type of autologous-tissue breast reconstruction applied after mastectomy for breast cancer, without the emplacement of a breast implant prosthesis.echnically, the harvesting of the TRAM free-flap is relatively easy and fast; because it possesses a robust blood supply, there is a low risk of tissue necrosis, either of the flap or of the adipocyte fat, and the reconstructed breast can tolerate oncologic radiotherapy.

Triangles are just shapes with 3 (straight) sides. They can be big or small and can look somewhat different. Depending on the angles and the sides we can sort the triangles into different types. The simplest way to sort triangles is by their angle size: 1  Acute triangle: An acute triangle is one in which all the angles are acute (less than 90Â°). 2  Obtuse triangle: An obtuse triangle is one in which one of the angles is obtuse (more than 90Â°).
