In-Vivo Quantitative Mapping of the Perforasomes of Deep Inferior Epigastric Artery Perforators

摘要

Background:There is limited understanding of anatomy of perforator angiosomes, or “perforasomes,” of the deep inferior epigastric artery (DIEA). A perforasome is defined as the territory perfused by a single perforator vessel of a named artery, such as the DIEA. Given the clinical significance of this anatomical concept in microsurgical breast reconstruction, this study is a quantitative investigation of DIEA perforasome characteristics and patterns associated with perforasome size, perforator caliber, location and branching, using computed tomographic (CT) angiography.
