摘要
目的探讨超声造影技术在显示乳腺癌前哨淋巴通道(SLC)及前哨淋巴结(SLN)多样性中的应用价值。方法女性乳腺癌患者26例,术前均接受乳晕及深层腺体内注射超声造影剂行超声造影探查SLC和SLN。术中于乳晕及深层腺体内注射亚甲蓝,术后解剖蓝染的SLC和SLN,并进一步将超声造影探及的SLN及蓝染的SLN送病理检查。结果用超声造影技术,26例患者探及至少1条SLC及1个SLN。探及到3种类型的SLC,分别为浅层前哨淋巴通道(SSLC)、穿支前哨淋巴通道(PSLC)和深层前哨淋巴通道(DSLC)。探及到5种淋巴引流模式(LDP),分别为SSLC、PSLC、SSLC+PSLC、SSLC+DSLC和SSLC+PSLC+DSLC。超声造影探及的LDP与手术LDP相一致的患者为24例(92.31%)。6例患者探及到分叉的SLC;3例患者探及到中断的SLC,且相对应的SLN没有强化;术后病理证实该3例患者腋窝淋巴结均有癌转移。结论超声造影在术前评估乳腺癌SLC和SLN多样性中具有一定的可行性,并且对进一步SLN活检具有指导意义。
Objective To assess the application of contrast-enhanced ultrasonography in showing the variation of sentinel lymphatic channels （SLC） and sentinel lymph nodes（SLN） of breast cancer .Methods The SLC and SLN of 26 women with breast cancer were examined with intradermal and peritumoral injection of contrast microbubbles for ultrasonography before operation .The methylene blue was injected subareolarly and peritumorally during surgery .The SLC and SLN coloured with blue dye were anatomized after operation .The SLN detected by contrast-enhanced ultrasonography and coloured with blue dye were all sent for pathology examination .Results With contrast-enhanced ultrasonography ,at least one SLC and one SLN were detected in all 26 cases .Three types of SLC were detected ,which included superficial sentinel lymphatic channel （SSLC） ,penetrating sentinel lymphatic channel （PSLC ） and deep sentinel lymphatic channel （DSLC ） .Five lymphatic drainage patterns were found ,which included SSLC ,PSLC ,SSLC＋ PSLC ,SSLC＋DSLC and SSLC＋PSLC＋ DSLC .Of 26 cases ,the SLC of 24 cases showed by ultrasonography were consistent with those seen operatively with an accuracy rate of 92.31% .The bifurcated SLC was found in 6 patients . The discontinuous SLC was found by contrast-enhanced ultrasonography in 3 patients ,who had no enhanced SLN and were all confirmed histologically to have axillary lymph node metastasis of breast cancer .Conclusion Contrast-enhanced ultrasonography is feasible in evaluating the variation of SLC and SLN preoperatively in the patients with breast cancer and healpful in guiding the biopsy of the SLN .
