RESUMO
Heterodigital pedicle flaps have 2 possible patters of vascularization: anterograde flow (Littler) or reverse flow (Adani). The Adani's flap uses the Y-V pedicle lengthening principle. The flap is raised from the adjacent uninjured finger based on the digital artery. The common digital artery is ligated and a long pedicle is formed from the 2 converging digital arteries to supply a reverse flow flap. Four patients with severe fingertips injuries were submitted to surgical treatment with the Adani's flap. All flaps integrated and provided skin coverage. The Adani's flap has a long vascular pedicle that allows a wide arch of transposition. An easier vascular dissection in a site distant from the trauma which evolves a higher diameter digital artery and proximal interphalangeal arterial system promotes a high survival rate and good functional results. Adani's flap is a reliable technique for severe fingertip injuries.

Breast radiotherapy during childhood may cause unpredictable outcomes in soft tissue growth and may be responsible for most iatrogenic-related breast hypoplasias. Poor local skin quality and subcutaneous atrophy poses a difficult problem for the use of alloplastic tissues. Clinical use of a deep inferior epigastric perforator flap (DIEP) in oncological breast surgery is a common practice; however few studies have described its application in benign situations and no previous report addressed this subject. The authors indicate the use of the DIEP flap to correct severe hypomastia after previous childhood radiotherapy for hemangioma treatment, followed by unsuccessful alloplastic tissue reconstruction. For selected patients the DIEP flap may constitute a new alternative for complications of radiotherapy treatment due to the possibility of large tissue transfer with minimal donor area morbidity. The quantity of flap tissue necessary to restore the breast mound, the perforator vessel size, and the quality of suitable recipient vessels should be carefully evaluated. However, the need for microsurgical training as well as the extended surgical time are the main limiting factors for the use of this flap.
