  • As previously described, the majority of the perforators were located in a circular area 3cm diameter centred on the mid-point of a line between the anterior-superior iliac spine and the upper lateral border of the patella.

    1. 1. Microvascular abdominal flap reconstruction Stephen McCulley Consultant Plastic and Oncoplastic Breast Surgeon Nottingham
    2. 2. Advantages of abdominal autologous reconstruction <ul><li>“ Alive” and natural </li></ul><ul><li>Changes and ages with patient </li></ul><ul><li>Lower abdominal fat and skin ideal replacement </li></ul><ul><li>Large quantity tissue available </li></ul><ul><li>Potential for an improved abdomen (only flap with this potential) </li></ul><ul><li>Potential for an improved abdomen (only flap with this potential) </li></ul>
    3. 3. Bilateral DIEP Surgery ‘Optimal breast’ ‘Optimal abdomen’
    4. 4. Nottingham Breast Unit <ul><li> IMPLANT LD DIEP/ Free TRAM </li></ul><ul><li>Reconstruction </li></ul><ul><li>Primary 33% 42% 25% </li></ul><ul><li>Secondary 3% 27% 67% </li></ul>
    5. 6. Superior Epigastric Artery Pedicled TRAM Deep Inferior Epigastric Artery Free TRAM DIEA – DIEP flap Superficial Inferior Epigastric artery – SIEA flap
    6. 7. DIEP flap
    7. 8. Free TRAM or MS-TRAM
    8. 9. SIEA flap <ul><li>Advantages </li></ul><ul><ul><li>No impact on abdominal wall </li></ul></ul><ul><ul><li>Quicker to raise </li></ul></ul><ul><li>Disadvantages </li></ul><ul><ul><li>Smaller vessels making microsurgery more difficult </li></ul></ul><ul><ul><li>Vascular territory smaller so smaller flaps available </li></ul></ul>
    9. 10. SIEA flap pedicle
    10. 11. DIEP flap <ul><li>Advantages </li></ul><ul><ul><li>Minimal impact on abdominal wall </li></ul></ul><ul><ul><li>Quicker recovery </li></ul></ul><ul><li>Disadvantages </li></ul><ul><ul><li>Question over venous return and hence fat necrosis rate </li></ul></ul><ul><ul><li>Takes longer to do </li></ul></ul>
    11. 12. If the perforators are difficult do a TRAM or MS-TRAM <ul><li>DIEP trends are better strength, quicker recovery, less pain, lower abdominal complications </li></ul><ul><li>However the more perforators needed the higher complications so probably an inferior flap to TRAM </li></ul>
    12. 13. My use abdominal flaps <ul><li>DIEP flaps 70% </li></ul><ul><li>TRAM flaps 20% </li></ul><ul><li>MS-TRAM 5% </li></ul><ul><li>SIEA 5% </li></ul>

    15. 16. Impact on abdominal wall <ul><li>Pedicled TRAM Takes whole rectus WORST </li></ul><ul><li>Free TRAM Takes block of full width muscle </li></ul><ul><li>MS-TRAM Takes window of muscle </li></ul><ul><li>DIEP Takes no muscle but muscle split (nerve preserving) </li></ul><ul><li>SIEA Does not enter abdominal wall BEST </li></ul>
