ObjectiveTo summarize the complications after supraclavicular lymph node dissection for invasive breast cancer patients with ipsilateral supraclavicular lymph node metastasis but without distant metastasis, and to analyze its safty. MethodsA retrospectively clinical analysis of the complications of 98 invasive breast cancer patients with ipsilateral supraclavicular lymph node metastasis but without distant metastasis, who underwent supraclavicular lymph node dissection in our hospital from Jan. 2014 to Dec. 2015 was performed. ResultsThere were 20 cases of lymphedema (20.4%, 20/98), 4 cases of hypaesthesia (4.1%, 4/98), and 4 cases of abduction restriction of shoulder joint (4.1%, 4/98). No other serious complications occurred. There was no shape change of shoulder and upper arm abduction, facial edema, head and neck disorders, pleural effusion or chylothorax happened. The extubation time of drainage tube at axillary and chest wall in 78 cases was in 1 month after the operation, 18 cases was in 1-2 months, and 2 cases was in 2-3 months. There were 14 cases (14.3%) suffered from the ipsilateral axillary or pleural effusion after extubation. The extubation time of supraclavicular drainage tube in 98 cases was 3-7 days after the surgery, with the median of 4.5 days, including 3 cases (3.1%) of chyle leakage. ConclusionThe supraclavicular lymph node dissection has no serious postoperative complications, and is safe to patients with ipsilateral supraclavicular lymph node metastasis but without distant metastasis.
