| Abstract |
Purpose: Un-healing and centrally located defect on back area, it is sometimes a challenge for the reconstructive surgeon. Although skin grafts are considered as the first choice for reconstruction of large skin defect on the back region, it is not always helpful but vascularized flaps provide a superior functional and aesthetic outcome. The present study was designed to investigate the clinical anatomy of the lumbar artery perforator flap to reconstruct back ulcer.
Materials and Methods: Clinical anatomy study was undertaken using computed tomographic angiographic analysis. We identified the courses of lumbar arteries and its perforators, measured pedicle length by layers. The location of the perforator vessel was charted against anatomical landmarks.
Results: The pedicle lengths of the third and fourth lumbar artery perforator reached a mean of 27.8 mm and 37.1 mm respectively from superficial fascia to deep fascia. The fourth perforator was more laterally located than the third perforator and less than 1 cm above the iliac crest. A case in which the fourth lumbar artery perforator was used as flap pedicle is described.
Conclusion: For the reconstruction of central defect on the back area, the lumbar artery perforator flap coverage may be a good alternative option. Computed tomographic angiography can easily identify the course and location of lumbar artery perforators and can be helpful to elevate the flap successfully. |
