Abstract:

Objective To 3D reconstruct the angiosomes of the deep inferior epigastric artery (DIEA)using Mimics and CT supporting workstations, in order to provide morphological evidence for clinical application of different types of tissue flaps with the DIEA as the vascular pedicle. Methods The systemic arteriography using the mixture of lead oxide-gelatin or oxide-latex was performed on five fresh adult cadavers. ① Data serially scanned by 64 slice spiral CT were 3D modeled and analyzed in Mimics and CT supporting workstations respectively. ② The anterior abdominal walls of the five cadavers were sectioned, observed by layers dissection combined with X-ray examination. Results The DIEA distributed into musculoperitoneal branches, muscular branches, lateral branches and musculocutaneous perforators. 3 musculoperitoneal branches with the diameter≥0.5 mm, which had the same vascular pedicle with muscular branches and musculocutaneous perforators, respectively. Conclusions  Different types of tissue flaps with the DIEA as the vascular pedicle, such as the musculoperitoneal flap, muscle flap, cutaneous flap and composite flap, can be harvested to reconstruct complicated defects of different parts and of various types, especially for the through and through defects reconstruction in oromaxillo-facial region.
