OBJECTIVE, To study the direction, route and num- ber of SLCs and their relationship with SLN after subareolar injection of methylene blue and technetium 99m sulfur colloid （^99m Tc-SC）, and to explore the mechanism of sentinel lymph node biopsies produce false negative results in breast cancer patients and the method to improve the detectable rate, METHODS: ^99m Tc-SC was injected preoperatively, and methylene blue was injected by the same subareo-lar route just after anesthetic induction, and then SLNB was carried out according to SLCs in 93 breast cancer patients.

目的：通过乳晕下联合注射^99m Tc-SC和亚甲蓝，研究前哨淋巴通道的行走方向、途径、数量及其与前哨淋巴结之间的关系，以探讨乳腺癌SLNB出现假阴性的机制，并提出提高其检出率、减少假阴性的方法。

Results 42 of 45 patients had a history of subarachnoid hemorrhage for 1 to 3 times. 23 and 22 cases died separately before and after digital substract angiography. 5 cases of rebleeding was relating to angiography, 24 cases died during the "high risk" period (4 to 10 days after first rupture). Rebleeding accounted for a 7.2% mortality of aneurysms preoperatively in our study. Among them, 71% was attributable directly to rebleeding, whereas 29% to non-neurological complications.

Methods The clinical data of 12 patients from Mar 1993 to Jun 2008 with retrocaval ureter were retrospectively analyzed. All the 12 cases were correctly diagnosed preoperatively via the combination of imaging examinations, such as ultrasonography intravenous pyelography、retrograde pyelography、CT or magnetic resonance urography. Ten patients received conventional open surgery and two received retroperitoneal laparoscopic ureteral replacement and ureteroplasty.
