A 56-year-old female patient, with no significant comorbidities, presented with abnormal breast exam findings. Imaging revealed a 5.4-cm irregular nodule in the left breast, diagnosed as invasive breast carcinoma (NST, Grade 2). Neoadjuvant chemotherapy was initiated, leading to a reduction in lesion size. Surgical intervention included quadrantectomy, sentinel lymph node biopsy, and axillary lymphadenectomy, which revealed residual carcinoma and positive lymph nodes. Postoperatively, chylous drainage through a Portovac drain was observed, prompting reoperation, during which the injured lymphatic duct was identified. Conservative management with medium-chain triglycerides resulted in a progressive reduction of drainage. The patient was discharged on the 13th postoperative day, subsequently underwent adjuvant radiotherapy, and is currently receiving regular outpatient follow-up.
一名56岁女性患者，无明显合并症，因乳房检查结果异常就诊。影像学检查发现左乳有一个5.4厘米的不规则结节，诊断为浸润性乳腺癌（非特殊类型，2级）。开始新辅助化疗，病变大小缩小。手术干预包括象限切除术、前哨淋巴结活检和腋窝淋巴结清扫术，结果显示有残留癌和阳性淋巴结。术后观察到通过Portovac引流管有乳糜引流，促使再次手术，术中发现淋巴管受损。采用中链甘油三酯的保守治疗使引流逐渐减少。患者术后第13天出院，随后接受辅助放疗，目前正在接受定期门诊随访。
