Introduction: Implant-based breast reconstruction is associated with an increased risk of ischemic complications, which may result in implant loss, suboptimal aesthetic outcomes, and delays in adjuvant oncological treatment. Additionally, axillary surgery carries a risk of upper-limb lymphedema. Indocyanine green (ICG) angiography enables more accurate real-time assessment of tissue perfusion than clinical evaluation alone, while axillary reverse mapping (ARM) facilitates the preservation of upper-limb lymphatics. The integration of these techniques reduces complications and improves both functional and aesthetic outcomes. Materials and methods: A total of 208 breast cancer patients who underwent mastectomy followed by immediate implant-based breast reconstruction were enrolled in this case\u2013control study. The prospective intervention group received intraoperative ICG angiography at three time points and underwent ARM with ICG. Conventional surgical techniques were applied in the retrospective control group. Results: ICG angiography showed excellent diagnostic accuracy for predicting postoperative ischemic complications (AUC = 0.93, 95% CI 0.82\u20130.99, p < 0.001). Compared with the control group, patients in the ICG group had significantly lower rates of mastectomy skin flap necrosis (11.5% vs. 30.8%, p = 0.001), seroma (4.8% vs. 14.4%, p = 0.032), hematoma (1.9% vs. 9.6%, p = 0.033), and lymphedema (2.9% vs. 17.3%, p < 0.001). They also experienced shorter hospitalization (6.2 \u00b1 1.9 vs. 8.0 \u00b1 2.8 days, p < 0.001), fewer delays in adjuvant treatment initiation (16.3% vs. 32.7%, p = 0.010), and higher aesthetic satisfaction scores (81.41 \u00b1 10.12 vs. 76.03 \u00b1 9.74, p <0.001). Conclusions: Intraoperative indocyanine green angiography is a valuable tool for predicting ischemic complications in alloplastic breast reconstruction and is associated with reduced morbidity, fewer delays in adjuvant treatment, and improved aesthetic outcomes. Preliminary evidence suggests that axillary reverse mapping is associated with lower rates of upper-limb lymphedema.\n<\/p>\n","protected":false},"author":711744,"featured_media":7504,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[43],"tags":[],"class_list":["post-9068","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-clinical-data"],"acf":[],"yoast_head":"\n
