While surgical options exist to treat lymphedema after axillary lymph node dissection (ALND), the lymphatic microsurgical preventive healing approach (LYMPHA) has been introduced as a preventive measure performed during the primary surgery, thus avoiding the morbidity associated with lymphedema. Here, we highlight details of our operative technique and review postoperative outcomes. For our patients, limb measurements and body composition analyses were performed pre- and postoperatively. Intraoperatively, axillary reverse lymphatic mapping was performed with indocyanine green (ICG) and lymphazurin. SPY-PHI imaging was used to visualize the ICG uptake into axillary lymphatics. Cut lymphatics from excised nodes were preserved for lymphaticovenous anastomosis (LVA). At the completion of the microanastomosis, ICG was visualized draining from the lymphatic through the recipient vein. A retrospective review identified nineteen patients who underwent complete or partial mastectomy with ALND and subsequent LYMPHA over 19 months. The number of LVAs performed per patient ranged between 1–4 per axilla. The operating time ranged from 32–95 min. There were no surgical complications, and thus far one patient developed mild lymphedema with an average follow up of 10 months. At the clinic follow up, ICG and SPY angiography were used to confirm intact lymphatic conduits with an uptake of ICG across the axilla. This study supports LYMPHA as a feasible and effective method for lymphedema prevention.
Background: Staged expander-based breast reconstruction represents the most common reconstructive modality in the United States. The introduction of a novel tissue expander with an integrated drain (Sientra AlloX2) holds promise to further improve clinical outcomes. Methods: Patients who underwent immediate expander-based pre-pectoral breast reconstruction were identified. Two cohorts were created, that is, patients who underwent placement of a conventional tissue expander [133MX (Allergan)] (Group 1) versus AlloX2 (Sientra) (Group 2). The study endpoint was successful completion of expansion with the objective being to investigate differences in outcome following expander placement. Results: Fifty-eight patients underwent 99 breast reconstructions [Group 1: N = 24 (40 breasts) versus Group 2: N = 34 (59 breast)]. No differences were noted for age (P = 0.586), BMI (P = 0.109), history of radiation (P = 0.377), adjuvant radiotherapy (P = 1.00), and overall complication rate (P = 0.141). A significantly longer time to drain removal was noted in Group 1 (P < 0.001). All patients with postoperative infection in Group 1 required surgical treatment versus successful washout of the peri-prosthetic space via the AlloX2 drain port in 3 of 5 patients in Group 2 (P = 0.196). Furthermore, both cases of seroma in Group 1 required image-guided drainage versus in-office drainage via the AlloX2 drain port in 1 patient in Group 2 (P =0.333). Conclusion: The unique feature of the AlloX2 provides surgeons easy access to the peri-prosthetic space without altering any of the other characteristics of a tissue expander. This resulted in a reduced time to drain removal and facilitated management of postoperative seroma and infection.
Background: Nipple-sparing mastectomy is associated with greater patient satisfaction than non–nipple-sparing approaches. Although various nipple-sparing mastectomy incisions have been described, the authors hypothesized that incision location would impact the rate and location of ischemic complications to the mastectomy skin flap. Methods: A prospectively maintained database was queried to identify patients who underwent nipple-sparing mastectomy with immediate microsurgical reconstruction with a minimum postoperative follow-up of 12 months. The impact of incision location on postoperative ischemic complications was investigated. Major complications were defined as those that required reexploration in the operating room or inpatient management; minor complications were amenable to outpatient management. Multivariable logistic and linear regression were performed to investigate risk factors for postoperative complications following breast reconstruction. Results: Eighty-seven patients met inclusion criteria. The following nipple-sparing mastectomy incisions were used: radial with a periareolar extension (39 percent), inframammary fold (31 percent), vertical with a periareolar extension (22 percent), vertical (6 percent), and radial (2 percent). Seven patients (8 percent) had major complications, whereas twenty-six patients (29.9 percent) developed minor postoperative complications. Inframammary fold incisions were associated with significantly greater rates of mastectomy skin flap necrosis (p = 0.002), whereas periareolar incisions were associated with significantly greater rates of postoperative nipple-areola complex necrosis (p = 0.04). Conclusions: The authors report a significant association between incision location and ischemic complications to the breast skin envelope in microsurgical breast reconstruction. The authors observed a significant association of inframammary fold and periareolar incisions with mastectomy skin flap and nipple-areola complex necrosis, respectively. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
