Reconstruction of large soft tissue defects of the back is a challenging problem. Large defects of the back were reconstructed with multiple random pattern or local pedicled muscle (and skin graft) or musculocutaneous flaps. The clinical use of perforator flaps has demonstrated that harvesting of flaps on a single perforator is possible for reconstruction of large defects. We present a 71-year-old male with a lesion on his left mid back that measured 10 × 10 × 4 cm(3) . Biopsy of the lesion was consistent with dermatofibrosarcoma protruberans. Wide local excision of the lesion with 4 cm margin was performed. The soft tissue defect, ~20 cm in diameter, was reconstructed with a large propeller dorsal intercostal artery perforator (DICAP) flap. The DICAP flap measured 40 × 15 cm(2) based on a single perforator-lateral branch of dorsal rami of the seventh posterior intercostal artery on the right side. The perforator flap was elevated at the subfascial level and transposed 180° into the defect. The donor site on the right side of the back was closed directly. This case illustrates the size of the propeller DICAP flap that could be safely harvested on a single perforator from the dorsal rami of the posterior intercostal artery. To our knowledge this is the largest reported pedicled perforator flap harvested on a single perforator on the posterior trunk.
The retrograde limb of the IMV seems to be a safe alternate recipient vein in DIEAP and muscle sparing free TRAM autologous breast reconstruction. This study does not identify a significant reduction in overall fat necrosis or overall complications when using the 2 venous repair techniques versus the simple venous repair technique.
The vascular anatomy of the internal mammary artery perforators was documented using cadaveric dissections, angiograms, and computed tomographic angiograms analyzed with Materialise's Interactive Medical Imaging Control System. The diameter, point of perforation, course, and relationship to surrounding anatomical structures has been shown using a vascular injection technique and three-dimensional reconstructions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
