The Influence of Subfascial Transaxillary Breast Augmentation in Axillary Lymphatic Drainage Patterns and Sentinel Lymph Node Detection

“…4 -11 From an epidemiologic point of view, as this patient population ages, an increasing number of breast cancer cases among women with previous transaxillary augmented breasts can be estimated. [12][13][14] More recently, sentinel lymph node (SLN) detection through preoperative lymphoscintigraphy (LSG) and biopsy has been indicated as an alternative to axillary lymph node dissection in patients with negative lymph nodes. [15][16][17][18][19][20][21][22] Given the use of SLN biopsy, some surgeons may be cautious in proposing a transaxillary approach for fear of disturbing the normal lymphatic drainage.…”

[12][13][14]24,25 In spite of the absence of controlled studies, some authors suggest that previous axillary surgery may hypothetically compromise the lymphatic drainage to the axilla.…”

“…22,25 Our previous observation has demonstrated that the axillary lymphatic channels can be preserved and that SLN mapping is feasible with this technique. 13,14 However, prospective controlled studies and larger clinical series are not available to analyze the accuracy of the procedure in patients with previous TBA. 14 Additionally, to date no information is offered evaluating the effect of LSG drainage patterns and SLN detection in patients with TBA.…”

“…13,14 However, prospective controlled studies and larger clinical series are not available to analyze the accuracy of the procedure in patients with previous TBA. 14 Additionally, to date no information is offered evaluating the effect of LSG drainage patterns and SLN detection in patients with TBA. The aim of this study is to present the early results of a prospective controlled cohort study analyzing SLN detection and lymphatic drainage patterns through comparative pre-and postoperative LSG (Po10 days-LSG) in patients submitted to TBA.…”
