When harvesting a vascularized lymph node groin flap (VGLNF) one of the major concerns is the potential risk of iatrogenic lymphedema of the donor\u2010site. This article helps understanding of the lymph node distribution of the groin in order to minimize this risk.<\/jats:p><jats:p>Materials and Methods: Fifty consecutive patients undergoing abdominal mapping by multi\u2010detector CT scanner were included and 100 groins analyzed. The groin was divided in three zones (of which zone II is the safe zone) and lymph nodes were counted and mapped with their distances to anatomic landmarks. Further node units were plotted and counted.<\/jats:p><jats:p>Results: The average age was 48 years. A mean number of nodes of 6.5\/groin was found. In zone II, which is our zone of interest a mean of 3.1 nodes were counted with a mean size of 7.8\u2009mm. In three patients no nodes were found in zone II. In five patients nodes were seen in zone II but were not sufficient in size or number to be considered a lymph node unit. On average the lymph node unit in zone II was found to be 48.3\u2009mm from the pubic tubercle when projected on a line from the pubic tubercle to the anterior superior iliac spine, 16.0\u2009mm caudal to this line, and 20.4\u2009mm above the groin crease. On average the lymph node unit was a mean of 41.7\u2009mm lateral to the SCIV\u2010SIEV confluence.<\/jats:p><jats:p>Conclusion: This study provides increased understanding of the lymphatic anatomy in zone II of the groin flap and suggests a refined technique for designing the VGLNF. As with any flap there is a degree of individual patient variability. However, having information on the most common anatomy and flap design is of great value.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jso.24682","type":"journal-article","created":{"date-parts":[[2017,5,25]],"date-time":"2017-05-25T20:22:40Z","timestamp":1495743760000},"page":"378-383","source":"Crossref","is-referenced-by-count":22,"title":["The vascularized groin lymph node flap (VGLN): Anatomical study and flap planning using multi\u2010detector CT scanner.
