目的：评价旋髂深静脉作为早期宫颈癌髂外淋巴结切除术尾侧界限的标志的效用。方法：在对髂外血管远端（尾侧）、前侧（腹侧）进行解剖并结合宫颈癌根治性子宫切除术时，仔细寻找旋髂深静脉。紧邻该静脉上方的淋巴结被发送为邻近淋巴结，静脉尾部的淋巴结被发送为远端。测量从静脉到股管的距离。结果：对 71 名女性进行了 40 个月的研究。 55 人患有鳞状细胞癌，15 人患有腺癌，1 人患有腺鳞癌。旋髂深静脉至股管的平均距离为 16 毫米。 63 名患者在已确定的旋髂深静脉远端进行了解剖，其中 49 名患者 (77%) 切除了远端淋巴结。切除的盆腔淋巴结中位数为 24 个（范围为 9 至 68 个），每侧切除的远端淋巴结中位数为 1.0 个。 13 名女性 (18%) 发现淋巴结转移。一名具有多个肉眼可见阳性淋巴结的受试者有一个阳性远端淋巴结。因此，大多数早期浸润性宫颈癌患者均发现少量远端淋巴结，其中8%的阳性淋巴结受累于该淋巴结组。结论：旋髂深静脉是髂外淋巴结清扫尾部界限的合适标志。 (C) 1999 年，美国妇产科医师学会。
Objective: To evaluate the utility of the deep circumflex iliac vein as a landmark for the caudal limit of external iliac lymphadenectomy for early cervical cancer.Methods: During dissection of the distal (caudal), anterior (ventral) aspect of the external iliac vessels in conjunction with radical hysterectomy for carcinoma of the cervix, a careful search was made for the deep circumflex iliac vein. Lymph nodes immediately above this vein were sent as adjacent and lymph nodes caudal to the vein were sent as distal. The distance from the vein to the femoral canal was measured.Results: Seventy-one women were studied over 40 months. Fifty-five had squamous cell carcinoma, 15 had adenocarcinoma, and one had adenosquamous carcinoma. The mean distance from the deep circumflex iliac vein to the femoral canal was 16 mm. Sixty-three patients had dissections distal to identified deep circumflex iliac veins and 49 (77%) of these had distal lymph nodes removed. The median number of pelvic lymph nodes removed was 24 (range nine to 68), and the median number of distal lymph nodes removed was 1.0 from each side. Lymph node metastases were found in 13 women (18%). One subject with multiple macroscopically positive nodes had a single positive distal lymph node. Thus, a small number of distal lymph nodes were found in most women with early invasive cervical cancer, and 8% of those with positive nodes had involvement of this nodal group.Conclusion: The deep circumflex iliac vein was an appropriate landmark for the caudal limit of external iliac lymphadenectomy.
