Internal mammary artery and vein supercharge in TRAM flap breast reconstruction.
To improve the blood supply of the pedicled flap we have performed an additional microvascular augmentation to this type of breast reconstruction procedure since 1991. The ipsilateral deep inferior epigastric pedicle is anastomosed to the internal mammary artery and vein (IMAV supercharge). In 19 of 20 patients this technique proved to be feasible. For the venous anastomoses the 3M microvascular anastomosis system facilitated the procedure. In one patient the venous anastomosis failed due to the small calibre of two internal mammary veins. In a majority of the cases rapid improvement of flap perfusion could be observed as the direct result of the supercharging. The IMAV supercharged flap is quite comparable with the free flap as regards to the operative procedure. Disadvantages are a slightly more extensive dissection and less freedom in positioning the flap due to the presence of the superior muscular pedicle. The main advantage is that the supercharge procedure minimises the risk of total flap loss. Further technical improvement may be obtained by the use of a contralateral vascular pedicle dissected with muscle-sparing techniques.
